Reverse thrust seat for rocket launching

Abstract

The invention relates to a reverse thrust seat for rocket launching. The reverse thrust seat comprises a bottom (1), a wall (2), a round hole (3) or a sawtooth hole (4), a cavity (5) and a cylinder (7). The wall (2) and the bottom (1) of the cylinder (7) of the reverse thrust seat (11) is hermetically connected to form the cavity (5). The lower end of a rocket (8) is placed in the horizontal reverse thrust seat (11). The rocket (8) is coaxially arranged on the reverse thrust seat (11). Piles, arranged on the lower surface of the reverse thrust seat (11) and fixed to the reverse thrust seat (11), extend into the horizontal ground, and are clung to the ground. A cover seat (13) is arranged at the periphery of the lower end of the rocket, and is used for preventing hot air flow (9) from burning the rocket (8) out. Kinetic energy of the high-pressure hot air flow (9), emitted to the surrounding by the rocket (8) and sprayed horizontally, is collected by the reverse thrust seat (11) with the wall (2), is stored in the cavity (5), and is converted into energy for thrusting the rocket up, so that more energy is saved, and the weight of the rocket can be reduced.

Description

technical field [0001] The invention relates to a thrust reverse seat used for rocket launching. Background technique [0002] The rocket is a jet propulsion device that is ejected backward at a high speed by thermal air flow and uses the reaction force generated to move forward. It carries combustion agents and oxidizers by itself, does not rely on oxygen in the air to support combustion, and can fly in the atmosphere and in outer space. With the consumption of rocket propellant during the flight, the mass of the rocket decreases continuously, and it is a variable-mass flying body. Modern rockets are used as vehicles for sounding, launching artificial satellites, manned spacecraft, space stations, and boosters for other aircraft. Rockets for launching satellites are generally three-stage, the first stage has a large thrust, and the effective speed and height can be obtained in the vertical ascent section. After the existing rocket is initially ignited, the high-pressure t...

Problems solved by technology

Rockets for launching satellites are generally three-stage, the first stage has a large thrust, and the effective speed and height can be obtained in the vertical ascent section. After the existing rocket is initially ignited, the high-pressure thermal airflow ejected by the rocket is sprayed on the horizontal ground In fact, the hot air flow ejected from the rocket nozzle is scattered along the horizontal ground to the surroundings, and a large part of the reaction force of the launch is dispersed to the surroundings. The rocket does not make full use of the maximum vertical upward thrust from the ground. , this kind of flat plate uses the horizontal ground as the reverse thrust seat, which has the disadvantage of radiating and dispersing the reverse thrust to the surroundings, resulting in a large amount of waste of energy in the combustion of combustion agents and oxidizers, and increasing the mass of the rocket
