Split type omnibearing take-over laser booster

Abstract

The separate omnibearing laser receiving thruster comprises one or two optical systems, thrusting agent storage boxes, one or two burning chambers and spraying tubes, with the optical system at one side of the burning chamber, whose one side opens a transparent laser entrance portal, based on which, the optical system rotating and receiving all the laser beam of XY surfaces, accumulating to the center of the burning chamber through the optical system, with the trusting agent sprayed from the spray tube to generate forward thrusting. Complete separation of the optical system and the thrust system, free from the influence of high temperature and pressure thrust air flow, omnibearingly receiving laser beams from every direction, to adapt to all kinds of track conditions.

Description

technical field [0001] The invention relates to laser propulsion technology in the field of aerospace propulsion technology, in particular to a separate omnidirectional receiving laser thruster. Background technique [0002] In the field of aerospace propulsion technology, how to reduce launch costs and increase payloads has always been a hot spot in research and development. Traditional satellite launches require large-scale chemical launch vehicles. Fuel accounts for a large proportion of the launch weight, and the proportion of payloads in orbit is only about 1.5%. The launch cost is as high as $10,000 / kg, and the pollution is large. Taking my country's first artificial satellite as an example, "Dongfanghong" weighs 173kg. If 1.5% of the payload is used, the actual launch weight is: 11533kg. It can be seen that most of the energy is used to propel the propellant itself, resulting in energy loss. waste. Therefore, scientists have been exploring for a long time, seeking to...

Problems solved by technology

This type of design is shared by the focusing mirror and the nozzle of the thrust chamber, but has the following disadvantages: (1) The laser beam is coaxial with the thruster, and it is difficult to change the incident direction of the laser, which is not conducive to receiving laser beams incident from different azimuths and changing Flight direction; (2) It is difficult to achieve the optimum due to taking into account two points, such as focusing requires a parabolic shape, but as the thrust chamber and nozzle, the parabolic expansion is not necessarily the best; (3) With the temperature rise or pollution of the inner surface of the nozzle , will affect the reflective performance and easily cause the optical mirror to fail;

In order to adjust the laser receiving direction, an external optical receiving system is added in front of the focusing system, but in this way, the laser beam has undergone four reflections, which not only complicates the optical path, but also causes energy loss

Although this type of engine can adjust the direction of receiving the laser beam, its adjustment range is limited
