Abstract

The invention provides an integrated structure of a gas conduit for a liquid rocket engine, which includes sequentially connected: a turbine casing, a gas conduit collector, a rectifying grid, and a thrust chamber head inlet; the gas conduit collector is provided with a gas collecting ring, a gas conduit , collection ring and diversion column, gas pipes are symmetrically scattered on both sides of the gas collection ring and dispersion ring, presenting a flat structure. The high-temperature gas enters the thrust chamber head evenly after entering the turbine shell, gas collecting ring, gas pipe, collecting ring, diversion column, rectifying grid and thrust chamber head in sequence. The technical solution adopted in the present invention has a high degree of integration, can significantly improve the compactness of the connection structure, reduce the overall height of the engine, further reduce the height of the engine connection cabin, further reduce the height of the rocket, and reduce the weight of the rocket on the one hand , on the other hand, it reduces the difficulty of rocket control. For engines used in swing, the control torque of the engine servos is also reduced.

Description

technical field [0001] The invention relates to the technical field of rocket engine equipment, in particular to an integrated structure of a liquid rocket engine gas conduit. Background technique [0002] The air intake conduit at the head of the thrust chamber and the exhaust pipe of the turbine of the traditional pump-pressed liquid rocket engine are independent structures, and the two are connected by flanges at the docking position, and a gas sealing structure is set at the connection. After the two are connected, they form a gas Catheter structure. Usually, the inlet duct at the head of the thrust chamber is in the shape of a quarter-circle elbow, which completes the direction conversion of gas from horizontal to vertical. The overall height of the engine, thereby reducing the height of the rocket engine cabin, thereby reducing the height of the entire rocket. On the one hand, the weight of the rocket is reduced, and on the other hand, the difficulty of rocket control...
