SUMMARY:Experimental and Theoretical Investigation of the Guidance  System 
 of  an Exo-Atmospheric Kill Vehicle
DESCRIPTION:Lecturer:Vladimir Kurovsky\n Faculty:Department of Aerospace En
 gineering\,\n Institute:Technion – Israel Institute of Technology\n Loca
 tion:Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Ab
 stract: \n Details: \n One of the defense methods against ballistic missil
 es threat is to intercept them at the mid-course phase\, which is a part o
 f the ballistic trajectory that lays in space. At high altitude or in spac
 e\, an interceptor missile can be guided by moving the main motor nozzle\,
  known as TVC (Thrust Vector Control) or by reaction jets. Usually\, space
  interceptors are not equipped with explosive warhead\; therefore\, a hit-
 to-kill collision is required.  For this reason\, a TVC control may not b
 e sufficient because of its non-minimum phase feature\, which increases th
 e interceptor time constant. Therefore\, in the last few seconds before th
 e “end-game”\, it is best to maneuver using forward reaction jets guid
 ance or a combination of forward and tail reaction jets.\nThis research pr
 esents a theoretical and an experimental investigation of the solid propel
 lant based reaction jets guidance system for an exo-atmospheric intercepto
 r (kill vehicle). In the first part\, a theoretical model of the system wi
 th a number of interceptor versions and reaction jets system was built and
  solved numerically. The reaction jets and interceptors performance was in
 vestigated using a computer simulation\, integrated in a proportional navi
 gation (PN) guidance loop. In the second part of the research\, an experim
 ental system was designed and built\, whose purpose is to demonstrate the 
 work of the reaction jets system and to measure its thrust\, response time
 \, internal pressure and temperature conditions.
