Unmanned lunar ascender launch base stabilizer suitable for complex conditions

Abstract

An unmanned lunar ascender launch base stabilizer suitable for complex conditions comprises a launch base, upper sections and lower sections of supporting legs, trust reversers and supporting feet. The launch base is a platform, and the upper surface of the launch base is provided with a lunar lander upgrader. The lower section of each supporting leg is a T-shaped cylinder sleeved in the upper section of each supporting leg. The upper section of each supporting leg is connected with the lower surface of the launch base. The trust reverser is arranged outside the lower section of each supporting leg. Each supporting foot is connected with the lower section of each supporting leg through a spherical hinge. The trust reversers are four small solid rocket engines and are respectively arranged outside the lower sections of the four supporting legs. Each supporting foot is disc-shaped and connected with the lower portion of each supporting leg through the spherical hinge. By the adoption of the trust reversers and the trust generated from the trust reversers, the launch base is pressed against the lunar surface, so that the defect that the launch base is unstable when the lunar lander upgrader is ignited to take off in bad conditions is overcome, and stability of the lunar lander upgrader when ignited to take off is guaranteed.

Description

technical field [0001] The invention relates to an unmanned lunar surface ascending and launching base stabilization device suitable for complex working conditions, which can ensure that the lunar lander is on the ground under severe landing conditions such as a large slope on the lunar surface at the landing site, uneven lunar surface, or even a landing leg hanging in the air. Upgrading the stability of the launch base during ignition and take-off belongs to the field of aerospace technology. Background technique [0002] my country's lunar exploration is the third milestone in the aerospace industry after artificial satellites and manned spaceflight. Lunar exploration has a very high rate of scientific and technological output. It is an incubator of science and technology and will drive the innovation and development of basic science. Lunar resources have great strategic value and are an important support for the long-term sustainable development of human society; the moon...

AI Technical Summary

Problems solved by technology

First of all, the lunar lander is not manned. Due to the lack of environmental control and life support equipment, the quality is greatly reduced, making it too light, resulting in poor stability in the landing state; secondly, many detailed tasks that should be undertaken by astronauts cannot be completed. If a good landing point cannot be selected, the landing point of the lunar lander is not ideal. It is very likely that the lunar surface of the landing point is uneven such as the slope is greater than 15°, or the lunar surface is rough or even a landing leg is suspended in the air.

Under these conditions, even if the lunar lander can successfully land on the lunar surface, accidents such as overturning are likely to occur due to the complex dynamics of the upgraded engine plume when the lunar lander is upgraded and ignited to take off.
