This paper aims to describe the methodology used in design and manufacture of a fixed-wing aircraft manufactured using additive techniques together with implementation technology based on solar panels. The main objective is increasing autonomy range UAV’s autonomous missions. Moreover, one targets improve capabilities aeronautical industry towards sustainable aircrafts acquire better mechanical...

The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis...

In the field of aeronautics, shape morphing has been used to identify those aircraft that undergo substantial geometrical changes in their external shape to enhance or adapt to their mission profiles during flight. This creates superior system capabilities not possible without morphing shape changes. The objective of morphing concepts is to develop high performance aircraft with lifting surface...

The replacement of steam catapults with electromagnetic ones is becoming an overwhelming trend in aircraft launch systems. The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent...

The problem of attitude stabilization of a fighter aircraft is investigated in this paper. The practical aspects of a real physical system like existence of external disturbance with unknown upper bound and actuator saturation are considered in the process of controller design of this aircraft. In order to design a robust autopilot in the presence of the actuator saturation, the Composite Nonli...
