Adaptive design without service tower and oscillating bar for low-temperature rocket power system

Abstract

The invention relates to adaptive design without a service tower and an oscillating bar for a low-temperature rocket power system. The adaptive design comprises the following steps that all air supply, liquid supply and exhaust ports of the rocket power system are led to the bottom of a rocket; two withdrawing devices are arranged at the two sides of the rocket, a plurality of connectors are arranged and fixed to the withdrawing devices, the connectors are used for being in butt joint with the ports in the rocket testing and launching preparation stage, and air supply, liquid supply and exhaust are conducted on the rocket; and before the rocket is launched, the connectors automatically fall off, the withdrawing devices automatically and quickly withdraw out of the safety distance of the rocket, and the rocket is ignited to take off. The withdrawing devices are remotely controlled and at automatically withdrawn to a safe distance before launching. According to the design of a launching support system, the service tower and the oscillating bar do not need to be built, a ground launching support system is simplified, the design and construction of a launching site are simpler, the rocket launching cost is reduced, meanwhile, due to the fact that the service tower or an umbilical tower is not arranged, transverse drifting of the rocket after takeoff is not limited, and the takeoff safety is improved.

Description

technical field [0001] The invention relates to rocket launch technology, in particular to an adaptive design of a duty-free tower and a swing rod of a low-temperature rocket power system. Background technique [0002] In the field of aerospace, the rocket launch support system should have the functions of filling, gas supply and distribution, and power supply and distribution to meet the launch requirements. [0003] Domestic Long March series cryogenic liquid launch vehicles generally adopt the service tower + pendulum scheme, and the new generation of launch vehicles such as the Long March 5 adopt the service tower + umbilical tower + pendulum scheme to meet the rocket’s gas supply, liquid supply and power supply needs. The gas supply and liquid supply pipeline of the medium power system is connected to the rocket through the connector along the swing rod from the service tower. This kind of support system is relatively complicated, which makes the design and constructio...
