As all natural laws, Newtonian dynamics should be governed by Einstein’s Covariance Principle;i.e., being covariant under all coordinate transformations, even time-dependent transformations. But Newton’s Second Law,...
In this paper, the method of reliability test profile construction for air-launched spacecraft is analyzed, in order to effectively carry out air-launched spacecraft flight reliability test. The flight mission profile...
This research paper presents a numerical study on the flow characteristics and performance of a baffled shock two-dimensional vector nozzle. The baffled shock vector nozzle is a type of fluid thrust vectoring nozzle t...
The transmission system is a critical power component of helicopters, playing an indispensable role in power transmission. Among its key elements, the planetary gear system is an essential part of the helicopter trans...
This paper presents an identification of a continuous-time linear aircraft model while considering control surface actuators using the maximal length sequence signal. In the identification with the actuator, the input...
In this note, we estimate the maximum amplitude for the Solar Cycle 25. We use the curvature technique presented for earlier cycles by Verdes and coworkers. We further extrapolate the location of the solar maximum num...
This paper is focused on a higher-level report of a new generation of Unmanned Aerial Vehicle (UAV) technologies. Starting from the structural scalability of civil tiltrotors, design strategy and requirements for UAVs...
This manuscript presents a research proposal to investigate how hazardous attitudes among general aviation pilots influence pilot performance in aviation accidents. General aviation pilots train to maintain safe flyin...
Based on measured astronomical position data of heavenly objects in the Solar System and other planetary systems, all bodies in space seem to move in some kind of elliptical motion with respect to each other. Accordin...
The aviation industry is a sector that is developing, changing and growing every day in terms of technological and legal framework. There are generally three factors that enable airlines to hold on to the market. Thes...
