The automated transfer of flight logbook information from aircrafts into aircraft maintenance systems leads to reduced ground and maintenance time and is thus desirable from an economical point of view. Until recently, flight logbooks have not been managed electronically in aircrafts or at least the data transfer from aircraft to ground maintenance system has been executed manually. Latest airc...

The emergence and popularization of various fifth-generation fighter jets with supersonic cruise, super maneuverability, stealth functionalities have raised higher more comprehensive challenges for the tactical performance operational indicators air defense weapon systems. training systems requires simulated targets; however, traditional targets cannot simulate radar cross-section (RCS) distrib...

this paper is a case study of the cause of distress and evaltion of main runway (29 l-ll r) of mahrabad international airport in 1320 , this run way was built (1800 length & 60 width ) from pcc for small aircrafts. later on 1329 and 13 39 the length of this run way was inc reased to 3000 m and 4000m , respectedly was increased to 3000m and 4000m,respectedly .since 1320, this run wa y h a s bee ...

In the real military scenarios and particularly using Unmanned Aerial Vehicles (UAVs) that perform aspecific communication task; it is not desirable to have an antenna that covers a wide angle. Omni directional antenna transmits power into all directions and thus it gives transmitter benefits of increasing the probability of being detected by hostile receivers. This paper addresses the problem ...
