SUMMARY:Thrust Vectoring and After Burner System for Increasing Survivabili
 ty of Micro-Jet UAVs
DESCRIPTION:Lecturer:Dor Shitrit\n Faculty:Department of Aerospace Engineer
 ing\n Institute:Technion – Israel Institute of Technology\n Location:htt
 ps://technion.zoom.us/j/92658464337\n Zoom: \n Abstract: \n Details: \n A 
 major current threat on Unmanned Aerial Vehicles (UAVs) and Air-to-Surface
  Missiles (ASM) is being intercepted by Surface-to-Air Missiles (SAMs) wit
 h maneuvering capabilities. There are many methods to increase the surviva
 bility of such UAV and ASM while the challenge is keeping them cost-effect
 ive and relevant to the modern battlefield.\nOne of the ways to increase s
 urvivability is by improving agility. Agility of an aircraft can be improv
 ed by using thrust vectoring and activation of an after burner. It enables
  the platform to accelerate by operating the aft burner while vectorizing 
 the thrust -thus “breaking lock” from the potential threat.\nThis stud
 y aims to investigate such integration in micro turbo jet UAVs. It include
 s dynamic simulation of the after burner as well as the vectoring nozzle s
 ystems and their effect on the aircraft overall performance. A total of 3 
 engine power configurations (basic with constant nozzle\, adjustable nozzl
 e\, adjustable nozzle with aft burner) and 2 vectoring configurations (wit
 h/without) are examined.\nFor this purpose\, Dornier "DT-45" UAV and "SA7-
 Strella" SAM are chosen as target and interceptor demonstrators. Whole eng
 ine decks are created including designing engine control system to withsta
 nd the engine limitations during the transient state. Drag polar\, stabili
 ty &amp\; control derivations of the target and interceptor main character
 istics are estimated. Evasive maneuver is characterized\, and a dedicated 
 aircraft control system is implemented to support it.  Finally\, a quanti
 tative analysis for the joint contribution of thrust vectoring and after b
 urner to the survivability of the aircraft is introduced by implementation
  of interception simulation.\nZoom meeting
