Abstract

The invention discloses a plug isolating type dual-pulse engine for experiments. A pulse combustor shell I of the plug isolating type dual-pulse engine for experiments adopts a transparent material; afirst flange is arranged on an outer wall of one end of the pulse combustor shell I; the pulse combustor shell I is fixedly connected with a pulse combustor shell II through the first flange; a switching frame is arranged on the other end of the pulse combustor shell I; and the pulse combustor shell I is fixedly connected with a spray pipe through the switching frame. A groove is formed in any one end face of the switching frame, and is matched with a shape of the pulse combustor shell I; the pulse combustor shell I is fixed into the groove through bolts; and the spray pipe is fixed to the center of the other end face of the switching frame through a screw thread. The plug isolating type dual-pulse engine for experiments provided by the invention solves the problem that visualization cannot be realized on an interstage isolating device opening process and a collision problem of a plug, a wall of a combustor and a convergent section of the spray pipe.

Description

technical field [0001] The invention relates to double-pulse engine technology, in particular to an experimental plug-type double-pulse engine. Background technique [0002] The solid rocket motor is mainly composed of propellant charge, combustion chamber, nozzle and ignition device and other components. Because of its lack of sufficient flexibility in mobility, all countries regard the controllability of solid rocket motors, such as thrust vector control, thrust termination technology and multiple start technology, as important technologies to study. [0003] The double-pulse motor is the latest research achievement of the solid rocket motor. It is mainly composed of the main components such as the II pulse igniter, the II pulse combustion chamber, the interstage isolation device, the I pulse igniter, the I pulse combustion chamber and the nozzle assembly. , each combustion chamber has an independent igniter and is ignited separately. The interstage isolation device is a...
