PROBLEM TO BE SOLVED: To provide a pulse detonation device 10 for dividing a pulse detonation shock wave into an primary and control portion to reduce the strength of a propagating shock wave and/or change its direction.;SOLUTION: The device 10 contains a flow separator 14 which directs a portion of the shock wave into itself, thus reducing the shock wave's strength. In one configuration, the control region 16 converges in cross-sectional area so as to accelerate the flow in the control region (16), while the primary region 18 diverges to slow the flow in the primary region 18. The flow in the control region 16 is directed, at an angle, into the flow of the primary region 18 to impede and/or redirect the flow of the primary region 18.;COPYRIGHT: (C)2007,JPO&INPIT
