SUMMARY:The Hanin Prize Seminar - Harnessing Unsteady Forces to Achieve Pow
 erful Propulsion
DESCRIPTION:Lecturer:Prof. Ephraim (Effie) Gutmark\n Faculty:Department of 
 Aerospace Engineering and Engineering Mechanics\n Institute:University of 
 Cincinnati\n Location:Classroom 165\, ground floor\, Library\, Aerospace E
 ng.\n Zoom: \n Abstract: \n Details: \n Propulsion and combustion scientis
 ts and engineers have been fighting combustion instabilities in solid and 
 liquid rockets and in air-breathing propulsion systems for many decades. 
  This has been recognized as one of the most severe hindrances to the dev
 elopment of these engines because the unsteady pressure forces that are am
 plified under these conditions can result in destruction of the engine. 
   Engines are designed with various control strategies to keep pressure p
 ulsations from reaching excessive levels and often their operation boundar
 ies are set to avoid entering these dangerous zones.   More recently\, i
 nterest has been growing in the propulsion community in developing engines
  that\, by design\, operate in an unsteady manner.  These types of engine
 s are based on concepts such as pressure gain combustion or constant volum
 e combustion.  Though not new\, these technologies have the potential to 
 significantly increase the propulsive efficiency. This seminar will propos
 e an interesting possible link between the new insight gained from recent 
 research in the latter topic to the older problem of combustion instabilit
 ies.
