Abstract

PURPOSE: To make it possible to simulate the thermal environment, which is applied to the nozzle of a rocket motor at a high altitude, on the ground, by using a tested material for the nozzle skirt or the nozzle skirt internal layer to form the nozzle and by connecting a diffuser and a gas generating unit to the front and the rear respectively and by forming a low-pressure part in the diffuser.
CONSTITUTION: Cylindrical diffuser 6 is connected to the rear of ultrasonic nozzle assembling material 1, which has nozzle skirt inside layer 2 formed with a tested material, for example, a phenolic plastic material, by flange 8, and gas generating unit 10 is fixed to the front of material 1 by screwing in 12, and assembling material 1 is constituted by fixing nozzle throat 14 consisting of graphite materials and so on and nozzle skirt inside layer 2 to box body 5. The nozzle aperture ratio and L/D of the diffuser are so set that an impulsive wave may be generated in the diffuser and may be moved to the back stream to form a low-pressure region in the diffuser. As a result, the thermal environment applied to the nozzle at a high altitude can be simulated on the ground.
