Urban air mobility (UAM) represents a transformative approach to alleviating ground-level congestion by transitioning from two-dimension (2D) to three-dimension (3D) transportation systems. Envisioned as a safe, sustaina...

Abstract Lithium-ion batteries have always been a focus of research on new energy vehicles, however, their internal reactions are complex, and problems such as battery aging and safety have not been fully understood. In ...

Abstract The use of non-smart materials in structural components and kinematic pairs allows for flexible assembly in practical applications and is promising for aerospace applications. However, this approach can result i...

Abstract The assembly process of aerospace products such as satellites and rockets has the characteristics of single- or small-batch production, a long development period, high reliability, and frequent disturbances. How...

Abstract: During the last years, several thrust control systems of aerospace rocket engines have been developed. The fluidic thrust vectoring is one of them; it is simple in design and offers a substantial gain in weigh...

The purpose of this article is to investigate utilization of common-rail turbocharged diesel aero-engines as primary propulsion powerplant for light-to-medium helicopters and airplanes. This article summarizes the result...

ObjectiveThe 15Cr14Co12Mo5Ni alloy represents a new generation of low-carbon, high-alloy steels characterized by exceptional strength, elevated-temperature stability, and superior wear resistance, making it widely applic...

ObjectiveGears are central components of power transmission systems, and their surface integrity fundamentally dictates the reliability and fatigue life of high-end equipment. Ultrasonic vibration-assisted grinding (UVAG...

Abstract This study investigates the influence of graphene nanoparticle (GNP) reinforcement on the fatigue behavior of textile structural composites with unidirectional (UD), two-dimensional (2D) satin, and three-dimensi...

In order to explore how different mass ratio combinations of virgin high-density polyethylene (V-HDPE)/recycled high-density polyethylene (R-HDPE) affect fibre and print quality, this study conducts a series of analyses....

In three-phase unbalanced systems, where the circulation of zero sequence current is necessary, four-leg converters provide a neutral connection for single-phase or other unbalanced loads typically utilized in three-phas...

Ground handling delays at major airports pose significant challenges, impacting operational efficiency, airline schedules, and passenger satisfaction. This study explores the root causes of these delays, including resour...

Aviation around the world has integrated into a global system. As the integration process continues, more aspects and levels of it need to be lead towards the sustainable development of the whole system via advancing str...

Unmanned aerial rotorcraft vehicles have many military, commercial and civil applications. There is a necessity to advance the performance on several ranges of rotorcraft for using these vehicles successfully in the expa...

This paper presents an introductory overview of principles of the three-layer hierarchy of active fault-tolerance, providing, determination of the fault type with as many details as enough to get recoverable fault reason...

On July 23, 2019, the Federal Aviation Administration (FAA) expanded the Low Altitude Authorization and Notification Capability (LAANC)—the system that processes airspace approvals for sUAS operators in controlled airs...

The main objective of this original research article is to understand the short-term dynamic behavior of the transport-category airplane during landing flare elevator control application. Increasing the pitch angle to ar...

Pilot Reports (PIREPs) are an important source of information that aids, other pilots, air traffic control, and operational aviation meteorologists in terms of forecasting and updating weather advisories such as SIGMETs....

The regulatory requirements and guidance for showing compliance with the Federal Aviation Administration anthropometric considerations in aircraft design are widely dispersed in an array of source documents. Consequently...

AI (Artificial intelligence) can automate the process of generating optimized flight routes using real-time data, such as AIRAC (Aeronautical Information Regulation and Control), significantly reducing the time needed fo...

The current slot allocation mechanism in Brazil, based on the International Air Transport Association (IATA) rules, and its supplementary local regulation The National Civil Aviation Agency (ANAC), displays a few issues ...

The purpose of this study was to discover if a relationship existed between the most common safety concerns and the most common UAS accidents with regards to the integration of military unmanned aerial systems (UAS) into...

Radiation from both natural and artificial sources is an inescapable and undeniable reality of human existence. Aside from exposure to radiation from a wide variety of natural sources including background ionizing radiat...

Flying into hazardous weather can be a cause of aviation incidents and accidents. Accidents involving general aviation (GA) pilots who are not instrument rated who fly into instrument meteorological conditions (IMC) are ...
