Authors: Davydov I. A.
Published: September 2022

The given article represents the study of the influence of color, surface finish and shape of dents on the reliability of 3D surface dents visual inspection, which are formed due to damage to epoxy composite materials reinforced with carbon fiber resulted from impacts. This article provides an analysis of the influence of surface color of aircraft structural components made of composite materials on the reliability of a visual inspection. The test results are given. Using these values, it is possible to determine the cross-section profiles of surface defects caused by impacts with energy within the range from 5 J to 80 J. The new designs of aircraft, which have been put into service thus far, feature 50 % and more composite materials of the airframe mass and use monolithic carbon fiber composite panels for the fuselage skin. Carbon fiber composite is particularly sensitive to the post-impact compressive strength reduction, and the operating aircraft environment is characterized by an array of sources of impact damages. Samples of the surface appearance of real composite structures of the aircraft on impact is the confidential information. Currently available literature concerning impact damage to composite materials, focuses on impact testing using hemispherical impact elements of typical diameters Ø 15mm, Ø 20 mm or Ø 25 mm. Testing information regarding larger diameter samples is not provided. There is no published research into impact damages to monolithic, fully finished carbon fiber composites.
Effect of engine failure on aerodynamic characteristics of a light transport aircraft model
Authors: Mikhailov Yu. S.
Published: September 2022

In-flight engine failure has always been a hazardous situation in case of a single-engine aircraft associated with losing altitude and making a landing within the available gliding range. In the event of a multi-engine aircraft, this situation improves markedly due to the potential flight continuation. The necessary conditions to continue a flight are available excess thrust, satisfactory aerodynamic performance, and a fixed-wing control. If the half of engine thrust is lost, which adversely affects a rate of climb, the most critical flight modes are the take-off and go-around procedures performed at low altitudes using the engine asymmetric thrust. Ensuring flight safety in these modes requires extensive experimental studies in wind tunnels to simulate the basic flight envelope with an inoperative engine.

   The aim of studies is the effect of a critical engine failure on the aerodynamiccharacteristics of an aircraft model as well as ensuring the required efficiency of the flight controls to dampen the yaw and roll moments that arise during an asymmetric thrust flight.

   The complexity of solving the problem is determined by the necessity of recovering from the substantial yaw, roll moments and by a significant decrease in the wing lifting efficiency along with an increase in a drag force which limits a climb rate and aircraft control. This article presents an analysis of the effect of critical engine failure on the aerodynamic characteristics of a light twin-engine transport aircraft model in the wing take-off and landing configurations. The aircraft aerodynamic configuration is made according to the classic pattern with the high-mounted tapered wing and deck-type empennage. The high lift devices comprise a double-slot hinged flap with a fixed deflector. The aircraft is equipped with a loading ramp with a relatively short flat rotatable part of the lower fuselage surface. Experimental studies of the longitudinal and lateral characteristics of the model with installed simulators of a power plant were carried out in TsAGI low-speed wind tunnel T-102. The analysis of engine failure effect on the model aerodynamics was executed in changing the load factor within the range B = 0.3…2. The capabilities to dampen the yaw and roll moments, using the primary flight controls (rudder and ailerons), were determined.

Published: September 2022

Objectives: The banking sector has been impacted more negatively by the COVID-19 pandemic. At the same time, bank concentration and capitalization stabilize banking systems during times of crisis. This study evaluated the monthly financial reports of all commercial banks in Indonesia to investigate the joint impact of the COVID-19 pandemic and bank concentration on bank stability. Moreover, this study was conducted to determine whether adequate capitalization could enhance the positive effect of the interaction between COVID-19 and bank concentration during the pandemic. Methods/Analysis: Using 108 commercial banks between March 2020 and May 2021, data were analyzed using the fixed-effects estimator with heteroskedasticity and within-panel serial correlations for robust standard errors. Several robustness checks were performed to ensure that the results were accurate and consistent. Findings: Subsequently, the impact of the pandemic and bank concentration was determined to be significant and adverse, though their interplay was strong enough to promote bank stability. This highlights the importance of adequate capitalization in enhancing the beneficial effects of the interaction between COVID-19 and bank concentration on bank stability. Novelty /Improvement: Hence, these ﬁndings contribute to the literature on bank stability and have important policy implications for the banking sector during this pandemic.JEL Classifications: E51, G20, G21. Doi: 10.28991/esj-2022-SPER-018 Full Text: PDF
El español neutro en el doblaje latino
Authors: Martínez Moreno Enrique
Published: September 2022

El presente trabajo tiene por objeto problematizar, desde los elementos teóricos que ofrece Pierre Bourdieu, el denominado español neutro de los doblajes latinoamericanos. Esto con la finalidad de situarlo como un fenómeno simbólico definitorio de una realidad de consumo audiovisual específica, cuya gestación se ubica en los primeros años de la Guerra Fría y permanece hasta nuestros días. Lejos de pensar la neutralidad con relación a la unidad de la lengua española, este trabajo identifica al español neutro como una variante donde predomina el acento del centro de México y como una estrategia originalmente estadounidense guiada por los intereses de la industria fílmica. A partir de ello, se considera la creación de este español como un proceso violento de imposición en el marco de una disputa simbólica entre agentes tales como productoras, empresas de doblaje, consumidores, etcétera. Por último, el artículo analiza aquellos intereses geopolíticos, económicos y culturales que esconde el español neutro, en un intento por señalar a los principales beneficiarios de su uso.

Menurut survey Demografi Kesehatan Indonesia tahun 2018 ibu yang menyusui secara ekslusif sampai usia 6 bulan sebanyak 56%, salah satu pengaruh dari pemberian ASI Ekslusif adalah kelancaran produksi ASI yang diperngaruhi oleh beberapa faktor salah satunya yaitu status gizi dan paritas tahun 2018 menyebutkan bahwa ibu yang mengalami gangguan produksi ASI atau ASI tidak lancar sebesar 67% dari seluruh ibu menyusui. Tujuan dari penelitian ini adalah ingin mengetahui Hubungan Antara Status Gizi Dan Paritas Dengan Kelancaran Produksi Asi Pada Ibu Post Partum Di Wilayah Kerja Puskesmas Cipanas Kabupaten Garut. Penelitian ini merupakan penelitian analitik korelasi dengan pendekatan Cross Sectional dengan Populasi penelitian adalah ibu nifas hari ke 3-7 sebanyak 44 orang dan sampel 31 orang yang diambil dengan menggunakan teknik Purposive Sampling. Instrumen penelitian berupa kuesioner dan data dianalisis menggunakan Uji Statistik Spearman-Rho. Hasil penelitian didapatkan dari 31 responden, 11 responden (35,5%) merupakan primipara dan ASI tidak lancar, 15 responden (48,4%) status gizi mengalami KEK dan ASI tidak lancar. Ada hubungan antara status gizi dengan kelancaran produksi ASI (Ρ_value 0,004) dan ada hubungan antara paritas dengan kelancaran produksi ASI (Ρ_value 0,001). Kekuatan hubungan dapat dilihat dari nilai OR status gizi 27,429 kali lipat dan Paritas 0,915 kali lipat. Artinya Status gizi 27,429 kali lipat lebih besar pengaruhnya daripada paritas dan selebihnya di pengaruhi oleh faktor lainya. Dapat meminimalis risiko penyebab kelancaran produksi ASI salah satunya yaitu meningkatkan status gizi pada ibu nifas.
