## 1 Introduction  
A solid propellant rocket motor functions as a pressurized container with a single opening, the nozzle, as shown in Figure 1. Inside this container is a solid block formed by a specific mixture of fuel and oxidizer, the propellant [1]. When the ignitor ignites this mixture, a chemical reaction generates gases under high pressure. Due to the difference between the internal and external atmospheric pressure, these gases are rapidly expelled through the nozzle. The expulsion of gases at high-speed results in a force that moves the rocket forward. This reaction force, known as thrust, is directly proportional to the mass and velocity of the gases expelled through the nozzle [1]. Therefore, the greater the quantity and velocity of the expelled gases, the greater the thrust generated. Besides solid propellant rocket motors, this work focuses on a range of other technologies with similar applications currently being studied. Among them, we can mention liquid propellant, hybrid, gel rocket engines, and their derivatives. The development and optimization of rocket propulsion systems have been at the forefront of aerospace engineering due to their critical role in enabling space exploration and satellite deployment. Solid rocket motors (SRMs) stand out for their simplicity, reliability, and ability to deliver high thrust in compact designs. Recent advancements in solid propulsion technologies have expanded the performance envelope of SRMs by introducing innovative materials, geometries, and control strategies. For instance, as investigated by [PERSON] et al. [2], electric solid propellants offer new avenues for controlled ignition and throttling capabilities, which are essential for multimode propulsion systems. Beyond traditional SRMs, hybrid rocket technologies have also shown significant promise. A recent study by [PERSON] et al. [3] demonstrated how innovative fuel grain geometries, such as star-fractal swirl designs, can enhance combustion efficiency and performance. [PERSON] et al. [4] showcased how machine learning and evolutionary algorithms could produce novel grain configurations tailored to specific performance goals, eliminating the need for traditional empirical approaches. Control strategies play an equally vital role in advancing propulsion systems. A study by [PERSON] and [PERSON] [5] highlighted how innovative control algorithms, including fuzzy PID control and feedback linearization, can improve thrust modulation and pressure stability in variable-thrust SRMs. Figure 1: Cutaway view and operating principle of solid propellant rocket motor. Additionally, the integration of structural health monitoring systems into SRMs, as discussed by [PERSON] et al. [6], introduces new paradigms for ensuring the safety and reliability of propulsion systems through non-invasive diagnostics. In tandem with these advancements, efforts to tune the ballistic performance of solid rocket motors through material innovations have also gained attention. A study by [PERSON] and [PERSON] [7] revealed how embedded metal wires could strategically enhance burn rates and overall motor performance. Technological advancements in rocket engines have been vital for developing new capabilities in dual-use missions. The future of rocket engines points to new technological frontiers, with more powerful, environmentally friendly, and reliable engines, promising to transform space travel and open new possibilities for various applications. Firing static tests is essential to assess technological advancements in rocket engines effectively. They play a critical role in developing and validating propulsion technologies, providing valuable data for ensuring the performance, reliability, and safety of engines before they are used in flight. Static tests are conducted with the rocket motor secured on a test stand, allowing for the measurement and detailed analysis of its performance under controlled conditions.
