The rapid urbanization and population growth we 're witnessing have given rise to new challenges in meeting the escalating demands for cargo transporta tion within densely populated urban areas. Conventional ground-based transportation systems, often hampered by traffic congestion and infrastructure limitations, are pr oving increasingly inadequate to support the burgeoning logistical needs of modern cities. These challenges ha ve underscored the necessity for innovative transportation solutions that are e fficient, sustainable, and capable of navigating the intricacies of urban environments. Companies like Uber have demonstrated their potential in meeting customers' demands for passenger transportation. They operate efficientl y, allowing customers to order rides and make payments through their smartphones. Another di vision of uber company known as uber elevate focused specifically Uber on the development a nd implementation of Urban Air Mobility (UAM) solutions, such as electric vertical takeoff a nd landing (eVTOL) aircraft for passenger and cargo transportation within urban areas. While it is part of the larger Uber orga nization, Uber Elevate has a distinct focus on the aerial mobility sector and aims to provide on-demand air transportation services as an extension of Ub er's existing ground-based ride-sha ring platform. They have defined optimal aircraft performance standards for UAM and emphasize the importance of battery technology advancements. Uber Elevate has iden tified various challenges, including safety, infrastructure, noise, emissions, and public pe rception, and is working to bring together stakeholders from different sectors, includi ng manufacturers, regula tors, and the public, to accelerate UAM development. They are also partne ring with aircraft manu facturers and promoting open-source collaboration to facilitate UAM's grow th and ensure safety (S traubinger et al., 2020). This involvement now serves as a role model for the air tran sportation industry. Fig 1. Uber Elevate Network in Crea ting Urban Air Mobility(Roma, 2020) Moreover, various approaches to achieving sust ainable transportation have been adopted. For instance, in some advanced cities, there has been notable progress in using couriers on bikes or motorcycles to deliver items to different locations within stipulated timeframes. The primary goal of using bikes as a mode of transportation is to bypass traffic and meet delivery expectations. However, this solution has its limitations, includi ng factors such as the reliability of the rider, traffic congestion, and unforeseen incidents or accidents that can aff ect delivery efficiency. While new technology has ignited fresh interest and investment in th e market, aircraft companies, government organizations, universities, and indivi dual researchers are activ ely engaged in urban mobility projects. Their collective aim is to transf orm urban transportation into a tangible reality in the near future. Significant technological develo pment and the increasing importance of comfort (CZECH, 2018) have made meeting the demands of urban transportation a top priority for many, with a focus on providing stress-free, safe, reliable, and time-efficient means of getting around. We have seen initiatives like the one conducted by (Bansal et al., 2016), who conducted an online survey to understand people's opinions on the adoption of new smart car technology, known as autonomous vehicles. Additionally, Anuj Puri (Pur i, 2016) conducted a survey on the use of UAVs for traffic surveillance, with a focus on their ap plication in traffic management. He proposed the use of UAVs as a secondary perspe ctive to provide real-time information for traffic surveillance, road conditions, and emergency response. NASA's research centers are also making dedicated efforts towards the development of sustainable transportation. Various methods of VTOL aircraft design and parts of the design process followed by NASA have been published by Despite transportation still presenting significant challenges, the utilization of urban airspace has emerged as one of the proposed solutions. This co ncept has been in development for several years and it's important to note that pi npointing the exact inception year of this research and intention is challenging because it has evolved over time in tandem with advancements in technology and infrastructure. In recent years, it has gained prominence under the name "Urban Air Mobility" (UAM). UAM envisions a new era of aerial trans portation within cities, significantly harnessing urban airspace. It relies on the c oncept of electric vertical takeo ff and landing (eVTOL) aircraft to provide on-demand, point-to-point air transportati on services within urban and suburban areas. Supporters of Urban Air Mobility (UAM) contend that electric aircraft represent a pivotal technological advancement, offering solutions to numerous challenges encountered by helicopter and small aircraft air taxi services. These electric aircraft are anticipated to surpass conventionally powered counterparts in short-range missions, th anks to their lower power-to-weight ratio, enhanced overall efficiency, and increased inte gration potential within the airframe(Parker D. Vascik, 2017). Furthermore, distributed electric propulsion technologies are being considered as a way to reduce aircraft noise levels and addr ess concerns regarding community acceptance. Additionally, there is a theoretical belief that fu lly electric aircraft might lower direct operating costs by as much as 20% when compared to traditional aircraft. This cost reduction is attributed to improved overall efficiency and decreased ma intenance expenses (Parker D. Vascik, 2017) The use of electricity as an alternative or supplem entary power source for aircraft is not a recent concept. The initial proposals fo r electrical propulsion systems in aviation date back to 1943, with the aim of harnessing the advantag es of distributed propellers and electric motors. In the period spanning from 1983 to 2003, NASA collaborated with AeroVironment to develop and operate four experimental flight test vehi cles. These endeavors were dedi cated to advancing the core technologies essential for fully electric solar-p owered flight. The four test vehicles, named Pathfinder, Pathfinder-Plus, Centurion, and He lios, were unmanned systems employed by NASA to refine concepts related to el ectric propulsion and distributed el ectric propulsion. These projects represented significant milestones in the develo pment of electric pro pulsion technologies for aviation.(Parker D. Vascik, 2017). In addition to these aerospace-specific innovations, progress in electric engine power density and battery technologies ha s been primarily driven by the automotive and heavy industries. The production scale of hybrid and fully electric cars is significantly larger than what electric aviation is expected to achiev e, resulting in substan tial resources devoted to advancing this technology.(Parker D. Vascik, 2017) Nevertheless, despite the developments seen in manned solar vehicles and high-altitude, long- duration solar Unmanned Aircraft Systems (UAS), it is unlikely that cost-effective fully electric regional or long-haul commercial airc raft will become feasible in th e near future due to limitations in energy storage capacity. However, at the sma ller end of the passenger and payload spectrum, electric propulsion, integration, and storage technologies have pr ogressed to the point where they could potentially support economically viable shor t-range aircraft suitable for on-demand mobility (Parker D. Vascik, 2017). Below are the manu facturers proposing to develop and produce On- demand Mobility (ODM) aircraft. Fig 2. On-d emand mobility aircraft manufacturers (Parker D. Vascik, 2017) The goal of Urban Air Mobility (UAM) is to address urban congestion challenges and provide faster, more efficient, and environmentally frie ndly transportation options within cities. Some advanced countries have already initiated its implementation, considering it a step towards building smart cities. However, fully real izing the potential of UAM requires innovative approaches beyond conventional fixed-wing aircraft and helicopters. This is where tiltrotor Unmanned Aerial Vehicles (UAVs) come into play—a cutting-edge technology that combines vertical takeoff and landing (VTOL) capabilities with efficient fi xed-wing flight, offering a unique solution for seamless cargo transpor tation in urban environments. This research embarks on a journey to expl ore the groundbreaking possibilities presented by tiltrotor UAVs in revolutionizing urban cargo transportation. By harnessing the inherent advantages of tiltrotor technology, such as VTOL, hover capabilities, and efficient forward flight, our aim is to usher in a new era of cargo logistic s marked by agility, speed, and sustainability. The significance of this research lies in its potentia l to reshape how we perceive cargo transportation in urban settings. Through an exhaustive review, th is study seeks to illumina te the feasibility and advantages of integrating tiltrotor UAVs into ur ban cargo transportation netw orks. It endeavors to address critical questions concerning operationa l efficiency, safety, a nd economic viability—all while aligning with broader goals of achieving sustainable and efficient urban transportation systems. In the following pages, we delve into the literature review, focu sing on past and present research on UAM and the advancements in this emerging technology. We also explore the intricacies of tiltrotor technology and its potential app lications in the cont ext of urban cargo transportation. By examining the current la ndscape, identifying challenges, and proposing innovative solutions, this research aims to provi de a comprehensive framework for the seamless integration of tiltrotor UAVs into urban air mob ility for cargo transportation. Through meticulous case studies and the lessons learned from the lit erature review, we aim to contribute to the realization of a future where cargo logistics in urban areas are transformed into a seamless, efficient, and sustainable operation. The following section presents the hierarc hy of relevant transportation technology. Fig 3. Hierarchy of new transportatio n technology(Parker D. Vascik, 2017) The timely and efficient delivery of goods is crucial for both businesses and consumers. Urban Air Mobility (UAM) technologies ho ld the promise of alleviati ng urban congestion and reducing delivery times. In this context, Unmanned Aerial Vehicles (UAVs) emerge as a disruptive force capable of reshaping the cargo logistics landscap e. However, the widespread implementation of UAM faces numerous technical, regulatory, and in frastructure challenges that demand attention. Many of these challenges have been thoroughly examined in various literature reviews, and sustainable solutions have been proposed to address them. LITERATURE REVIEW AND PROGRESS MADE. COMBINED REVIEW ON URBAN AIR MOBILITY Systems-Level Analysis of On Demand Mobility for Aviation (Parker D. Vascik, 2017) (Parker D. Vascik, 2017) discusse s a thesis that aims to asse ss the technology maturity of On- demand Mobility services with the goal of enha ncing scalability and profitability within the aviation industry while ensuring customer satisfac tion. The writer's focus is on the utilization of unmanned aerial vehicles (UAVs) and other aircraft to provide on-demand services to individuals. It's emphasized that more than 15 companies, including NASA, are actively developing and building on-demand technologies. Importantly, the thesis takes a comprehensive approach by anticipating aircraft-based On-Demand Mobility (ODM) services without getting into the intricacies of technology development. The primar y objective is to identif y operational constraints and evaluate potential solutions in both the s hort and long term. The analysis adopts a systems- level perspective, considering various interdisci plinary factors that may impact ODM services. These factors encompass restrictions imposed on ODM networks due to air traffic control, integration with ground infrastr ucture, load balancing within the network, interactions with unmanned aircraft, community noise concerns, and more. The research questions are struct ured into three key approaches: 1. Constraints: These encompass various critical factors, such as tec hnological, operational, regulatory, business, or system interfaces, th at could potentially hinder or restrict the implementation of ODM Aviation within the United States. 2. Externalities: These external factors may emerge as a result of the widespread adoption of ODM Aviation networks in the United States. It's essential to examine the potential societal impacts stemming from this prol iferation and how they might, in turn, shape the landscape of ODM Aviation. 3. Mitigation Strategies: This involves identif ying viable technology and policy options, both in the short and long term, to address the lim itations and negative cons equences associated with the implementation of ODM Aviation in the United States. The author has developed a comprehensive system to visualize the concept of ODM (On-Demand Mobility) aviation and to identify potential implem entation challenges in the United States. The methodology employed for the system design wa s straightforward and rooted in a deep understanding of the subject. The system focused on specific U.S. states as case studies and conducted a thorough analysis of their market structure concerning ODM aviation. Factors considered included commuting patterns, income levels, household valuati ons, and the presence of existing charter services. Subsequently, the system outlined a referen ce mission, aligning it with each state's specific aviation requirements. A concept of operation was then delineated, providing a detailed overview of how customers would place orders and use the se rvices to reach their destinations. Finally, a multi-domain analysis was conducted to offer a ho listic perspective on the potential operational challenges that an ODM aviation network might encounter. This approach allowed for a comprehensive examination of ODM aviation's feasib ility and potential obstacles within a specific U.S context. The overall research highlights th e market structure and market demand of ODM aviation. The author also raises concerns that if urban air mobility or on -demand mobility aviation is implemented without diligent and intentional planning, it could result in numerous negative externalities. This may disrupt the equilibrium between cities, unveil pr ivacy concerns due to aircraft flying at low altit udes generating noise unacceptable to society. Moreover, implementing aviation in the wrong way might pose security thr eats, allowing various ai rcraft to fly without authorization in a particular airspace, potentially providing o pportunities for malicious acts. Safety When Flying Unmanned Aerial Vehicles At Transpor t Infrastructure Facilities (Shvetsova & Shvetsov, 2021) In 2021, (Shvetsova & Shvetsov, 2021) analyzes a way to solve the ban on unmanned aerial vehicles over transport facilities in many count ries, especially airports. The ban on unmanned aerial vehicles over airports is due to the potenti al collision risks during the takeoff and landing of aircraft. Additionally, managing unmanned aerial ve hicles would impose an additional workload on airspace management agencies. In this study, factors for the safe use of unma nned aerial vehicles at transport infrastructure facilities are formulated. The study considers thes e factors and introduces a simple air tunnel to facilitate the movement of unmanned aerial vehicl es. This air tunnel is robustly constructed to shield unmanned aerial vehicles from pedestrian pathways. The method is implemented using sheet cellular polycarbona te, optical fiber, aluminum n-shap ed profiles, and aluminum profiled sheets for the creation of the air tunnel, ensuring both strength and lightness of the air tunnel. The author also emphasizes the operating movement of the UAVs inside the ai r tunnel to ensure the safe movement of UAVs and the items they are transporting. Rules are established for the movement from one UAV to another to avoid collis ions. Practical tests of the materials used in creating the air tunnel were condu cted, yielding various results. The results are as follows: the material did not affect the qual ity level of the radi o signal from the UAV to the operator, and it also did not affect the quality of the GPS signal used for UAV navigation. The material's strength was also confirmed through impact testing, where a 3kg metal disk was dro pped onto the material, resulting in damage to the metal disk but not affecting the integrity of the air tunnel. This suggests that items must be packaged secu rely to withstand poten tial incidents and that UAVs must also be protected when they come into contact with the sides of the ai r tunnel. The author provides an alternative way to avoid this damage by equipp ing the propellers of the UAVs with protective covers. However, this solution has drawbacks rela ted to the implementation of the air tunnel. It would require a substantial investment rather than utilizing existing airspa ce and effective mission planning of UAVs from one locatio n to another to avoid collisions. The implementation of the air tunnel is shown below. Fig 4. Designed Air Tunnel (Shvetsova & Shvetsov, 2021) Final Report Urban Air Mobility (UAM) Market Study (NASA, 2018) The Booz Allen Team (NASA, 2018) conducted a study on Urban Air Mobility (UAM) in 2018, focusing on three potential markets: Airport Sh uttle, Air Taxi, and Air Ambulance. They found that the Airport Shuttle and Air Taxi markets had s ubstantial potential, with a total available market value of $500 billion in the U.S. The study iden tified challenges and ba rriers, which can be categorized based on their potential mitigation through technology and market maturity. Challenges include high service costs, weat her impacts, high-density operations, battery limitations, noise and environmental concerns, in frastructure constraints, competition from existing transportation modes, and public safety and perception concerns. Some challenges can be addressed through technological advancements and market maturation, while others require long- term solutions. The team adopted four approaches to understand th e urban air mobility ecosystem, and they are as follows: 1. Scoping: Identifying missions that can be se rved with vertical take-off and landing (VTOL) vehicles. 2. Initial assessment: Focusing on three market analyses which center on preliminary market analysis and evaluating barriers. 3. Interim Assessment: Conducting a comprehensiv e analysis of the initial assessment. 4. Final assessment: Documenting le ssons learned and recommendations. In summary, the study assesses the potential of UAM markets, outlines ex isting challenges, and suggests strategies for overcoming them to realiz e the full potential of UAM in the transportation sector. Moreover, there's a compelling case for co nducting additional research aimed at providing the public with a more realistic grasp of UAM travel. This could be achieved through flight simulations or pilot programs, offering re spondents firsthand expe rience and insights. Additionally, exploring the infl uence of urban congestion on UAM perceptions could yield valuable insights, considering that commute dist ances and attitudes toward congestion vary among respondents. The study has also shed light on the complexities of weather impacts on UAM operations. While it's clear that Instrument Flight Rules (IFR) conditions can significantly affect piloted Visual Flight Rules (VFR) operations, th e impact becomes minima l for fully automated vehicles equipped with sensors for IFR flight. Thes e findings underscore the need for future studies to delve into specific case examples to accura tely capture weather-related barriers and their implications. Furthermore, the assumptions made about technology, operations, and market scenarios throughout this study hi ghlight the importance of regularly updating these assumptions to align with real-world developments. Future studies should closely mon itor technology infusion trends and sustainability factors. Factors Affecting the Adoption and Use Of Urban Air Mobility (Al Haddad et al., 2020) A transportation research was also conducted in the year 2020 which focused on the factors affecting the adoption and use of urban air mob ility(Al Haddad et al., 2020). This paper conducted an online stated preferen ce study involving 221 partic ipants worldwide, incl uding a subset of 97 Munich residents, to evaluate the acceptance and adoption of urban air mobility (UAM). By drawing upon factors commonly associated w ith technology and automation acceptance, particularly in the context of autonomous vehicles, the st udy aimed to generate hypotheses regarding this emerging mobility service. The resu lt of the survey provides valuable insights for policymakers and industry stakeholders , and those insights are as follows: - Safety Concerns: Policymakers should consid er regulations focusing on human control of UAM. - Environmental Concerns: It is necessary for policymakers to regulate environmental hazards produced by the UAVs. This includes regulating allowable noi se levels and flying altitudes of the vehicles to address comm unity acceptance among both users and non-users of urban air mobility. For industry stakeholders, the survey proposed insights for service attributes and social demographics. The service attribut es include meeting customer demands such as time and cost to attract the public, while the social demogra phic attributes emphasi ze targeting various backgrounds and cultural beliefs based on their sp ecific needs. An Overview of Current Research And Developm ents In Urban Air Mobility – Setting The Scene For UAM Introduction (Straubinger et al., 2020) This paper aims to provide a comprehensive ove rview of various research areas within the emerging field of Urban Air Mobili ty (UAM). It seeks to address questions and challenges related to the implementation of UAM, which has the potential to revolutionize passenger transport within and between urban areas. It covers a wide range of topics with in the UAM research community, including aircraft requirements and classificat ions for passenger transp ort within and between cities. It also delves into potential obstacles to the introduction of UAM, including issues related to certification, policy, traffic management, an d ground infrastructure. Additionally, it provides insight into past research and human developm ent in building a standa rd smart city known as UAM. The regulatory section discusses certification, past and current research and development, and expected methods of implementation. It addresse s the significant challe nges associated with ensuring the safety and regulatory compliance of urban air mobility (UAM) operations. Certification standards and regul ations are being developed by av iation authorities such as the European Aviation Safety Agency (EASA) and th e US Federal Aviation Administration (FAA) to govern UAM. EASA's proposed regulations for "Enha nced VTOL" aircraft, intended for urban air transport, are discussed. These regulations set safe ty standards similar to those applied to smaller commercial aircraft, limiting the num ber of passengers to five a nd establishing a maximum take- off mass. Moreover, they require th e design of aircraft to ensure co ntinued safe flight and landing even in the event of a critical propulsion system failure. The certification section also addresses the intr oduction of regulations re lated to airspace for UAM. It mentions the development of airspace ty pes, modalities, and access based on the U-Space concept, which supports unmanned aerial system s' operations. However, it highlights that implementing this concept may add more work fo r airspace management agencies. Furthermore, it emphasizes that certification extends beyond ai rcraft to include vari ous aspects, including training, landing areas (UAM pads), mainte nance regulations, ope rating organization requirements, air traffic management (ATM), a nd air navigation services (ANS). Databases on obstacles and terrain, security regulations for passengers and personnel, and addressing externalities such as noise, air polluti on, and congestion are also essential. The paper suggests that UAM might face regulator y interventions similar to those observed in other transport sectors due to factors like natural monopolies, externalities, and information asymmetry. While predicting regulatory responses is challenging, market-r egulating policies could be introduced to address these concerns in the UAM market. The Ground Infrastructure section di scusses the critical aspects relate d to the infrastructure needed for urban air mobility (UAM) operations, with a specific focus on the ground infrastructure requirements for take-off and landing, referred to as vertiports or vertistops. The paper highlights the lack of extensive research on UAM ground infr astructure despite its importance, especially during the high-risk flight pha ses of take-off and landing, as well as for ensuring vehicle throughput and accessibility. Various options for the placement of UAM ground infrastructure are discussed, including rooft ops, barges over water, inside highway cloverleafs, and on top of existing ground-transport infrastructure. The authors mention th at current research in this area
