The reliability of unsteady inlet e ow computations may be seriously degraded by the lack of experimentally validated compressor-face (outeow) boundary conditions. The commonly imposed oute ow conditions require a e ow variableto beconstant (pressure

The Quiet Spike is a concept developed by Gulfstream Aerospace Corporation that breaks up the sonic boom generated by an aircraft traveling at supersonic speeds. The concept employs a structural boom that extends forward from the fuselage. Spaced alo

The Gulfstream Quiet Spike is a telescoping forward fuselage extension that alters the bow shock of the classic N-wave pressure signature generated by aircraft traveling at supersonic speeds. The bow shock is broken up into sequence of weak shocks th

A morphing concept for a Quiet Supersonic Jet (QSJ) is presented that produces a shaped sonic boom with very low initial overpressure. Morphing of the aircraft involves lengthening the fuselage via an extendable nose spike. The extendable nose spike
