SUMMARY:Inlet Flow Distortions as a Source of Performance Degradation in Mi
 cro-Turbojet Engine Investigated through Experimental Quantification
DESCRIPTION:Lecturer:Yakov Paltiel \n Faculty:The Stephen B. Klein Faculty 
 of Aerospace Engineering\n Institute:Technion – Israel Institute of Tech
 nology\n Location:Classroom 240\, 1st floor\, Aerospace Eng. building\n Zo

 nes play a crucial role in various aerospace applications\, especially in 
 small unmanned aerial vehicles (UAVs)\, target drones\, and experimental a
 ircraft. The overall performance of these engines is highly dependent on t
 he efficiency of their air intake systems. The geometry and configuration 
 of the inlet and duct significantly influence pressure recovery\, airflow 
 distortion\, and ultimately\, the engine's thrust and fuel efficiency. Amo
 ng the most critical components affected by these factors is the compresso
 r\, which is designed to operate under steady and uniform flow conditions.
  When subjected to distorted or non-uniform inlet flow\, the compressor ca
 n suffer from performance degradation\, and in severe cases\, encounter in
 stability phenomena such as rotating stall and surge.\n\nThese challenges 
 highlight the importance of accurately quantifying the effects of inlet fl
 ow distortion on engine performance. However\, current predictive tools ar
 e often insufficient\, especially for Micro-Turbojet engines operating in 
 complex or compact airframe environments. There is a clear need for a reli
 able and experimentally validated method to evaluate performance losses re
 sulting from various inlet conditions.\n\nThis seminar presents the develo
 pment of an experimental approach for a small-scale Micro-Turbojet engine 
 to evaluate the effects of inlet distortions on engine performance. The re
 sults aim to support the optimization of air intake design and improve pre
 dictive capabilities for engine integration within specific airframes\, ul
 timately contributing to more efficient propulsion systems.\n Details: \n
