A simulated high-speed rotating engine

Abstract

The invention discloses a simulation high-speed rotary engine. The rotary engine comprises a combustion chamber, a plug cover, a rotary shaft sleeve, a fixing sleeve, a firing pin, a spring, two identical copper cylinders and two identical fish ropes; the plug cover is fixed at the inner side of the upper end of the combustion chamber, a spray pipe structure is arranged in the center of the top ofthe plug cover, and the rotary shaft sleeve is arranged in the plug cover; a spring support seat is arranged in the middle of the rotary shaft sleeve, and two earring through holes are symmetricallyformed in the side surface of the lower portion of the rotary shaft sleeve;the fixing sleeve is arranged in the rotary shaft sleeve, and the firing pin and the fixing sleeve are coaxially arranged; the head of the firing pin penetrates through the fixing sleeve to extend into the spraying pipe structure and makes contact with the inner wall of the throat of the spraying pipe structure, and the spring is arranged on the firing pin in a sleeved mode; and the combustion chamber rotates at a high speed and drives the plug cover, the rotary shaft sleeve and the fixing sleeve to rotate, the two copper cylinders do circular motion to generate centrifugal force, and the fish ropes pull the firing pin to generate downward vertical force. According to the rotary engine, the situation of engine explosion in the experiment process is avoided, and the safety coefficient of the test device is improved.

Description

Technical field [0001] The present invention relates to an engine simulation technology, and particularly relates to an analog high speed rotation of the engine. Background technique [0002] In the development of turbo-rocket, projectile BASE BLEED other weapons systems, including ballistic projectile acceleration phase often produce high-speed rotation, high speed rotation since the projectile, the projectile force and secured together by solid rocket motor drive is passive high speed rotation state. High speed rotation will be solid rocket engine thrust, pressure greater impact other performance parameters, such that the combustion characteristics of the solid rocket motor is obviously different from a state of not rotating. [0003] At present, for a variety of test parameters during high-speed rotation of the solid rocket motor is mainly done by the high-speed rotary table test, test engine test are traditional grain filling, grain requires ignition and combustion testing, t...

AI Technical Summary

Problems solved by technology

[0003] At present, the test of various characteristic parameters of the solid rocket motor at high speed is mainly done through the high-speed rotary table test. The traditional test engine is filled with grain, and the test needs to be ignited and the grain is burned. The process is very dangerous and safe. very low coefficient
