Description

The separation type omnibearing take-over laser booster
Technical field
The present invention relates to space flight Push Technology field laser Push Technology, particularly a kind of separation type omnibearing take-over laser booster.
Background technology
In space flight Push Technology field, how to reduce launch cost, improve the focus that capacity weight is research and development always.Traditional satellite launching needs large-scale chemical carrier rocket, and fuel has accounted for very big ratio in the throw-weight, and the capacity weight proportion of entering the orbit only is about 1.5%, launch cost up to, and pollute big.First artificial satellite with China is example, " Dongfanghong " number heavy 173kg, if 1.5% to be capacity weight, actual transmission weight is: 11533kg, the visible most energy is used for advancing propellant itself, causes the waste of the energy.So scientists is all being explored all the time, seek to replace the legacy transmission mode with new principle of propeller.
Laser advances (Laser Propulsion) to utilize the antagonistic force of the High Temperature High Pressure plasma flow of superlaser and the generation of working medium mutual action to promote the new ideas Push Technology that aircraft advances.
This imagination is that American scholar Kantrowitz at first proposed in 1972.Laser advances and can reach than high thrust (104N magnitude), can obtain again to be expected to be used for the Single Stage To Orbit of microminiature space vehicle than high specific impulse (more than the 103S), and the space propultion of aircraft or attitude adjustment.Because than leaping high, energy can be from remote ground or the input of space base laser, and self need not carry energy resource system, can improve the load of effectively entering the orbit (reaching more than 15%) of aircraft greatly, cost-cutting (it is estimated and can reduce by 1 more than the order of magnitude), pollution abatement simultaneously.Therefore, laser advances research to obtain the general attention in various countries and develops rapidly.
Typical case's representative of laser thruster is " bareboat (lightcraft) " model that Myrabo proposes, as shown in Figure 1, the bareboat model vertical launch of using the 10kW CO 2 pulse laser device will weigh 50g in 2000 has arrived the height of 71m, and applied for patent (Myrabo L N in 2002, Laser propelled vehicle, US Patent6488233B1,2002), the parabolical tail cone plays reflect focalization and expanding nozzle simultaneously in this model.This class design focus lamp and thrust chamber jet pipe all are shared, but have following shortcoming: (1) laser beam and propelling unit are coaxial, are difficult to change the laser incident direction, are unfavorable for receiving the laser beam and the change of flight direction of different azimuth incident; (2) because of taking into account 2 points, be difficult to accomplish optimum, need paraboloidal, but as thrust chamber and jet pipe, the parabolic type expansion is not necessarily best as focusing; (3) with temperature rise of jet pipe inside face or pollution, will influence reflecting properties, optical mirror plane was lost efficacy;
People such as Russia Ageichik have proposed a kind of " empty day laser propelling motor " (ASLPE, Airspace LaserPropulsion Engine) imagination, as shown in Figure 2, it is by twice rotational symmetry reflect focalization independently, has realized the unify separation of push system of focus optical.In order to regulate the laser pick-off direction, increased the external optical receiving system in focusing system the place ahead, but so, laser beam has passed through 4 secondary reflections, not only the light path complexity has also caused the loss of energy.Though this class driving engine can be regulated the direction that receives laser beam, the scope of its adjusting is limited.
Summary of the invention
Technology of the present invention is dealt with problems: overcome the deficiencies in the prior art, a kind of separation type omnibearing take-over laser booster is provided, the optical system of this thruster is thoroughly separated with push system, optical system is not subjected to High Temperature High Pressure to advance the influence of air-flow, the laser beam of any direction in comprehensive reception space is to adapt to various track conditions; And the tool optical system only focuses on through 2 secondary reflections, and simple in structure, light loss is less
One of technical solution of the present invention: for adopting the separation type omnibearing take-over laser booster of single beam engine structure, it comprises: optical system, propellant tank, combustion chamber and jet pipe, described optical system is positioned at the outer side of combustion chamber, on combustion chamber one side, have the laser incidence window of transparent circle, optical system serves as the axle rotation with the laser incidence window, realize receiving all laser beams in the xz plane, when the laser beam remittance is focused to the combustion chamber center, the propellant that ignition combustion is indoor, from jet pipe, spray, produce thrust forward, reach the purpose of propelling.
Two of technical solution of the present invention: the separation type omnibearing take-over laser booster that adopts dual-beam monomotor structure, it comprises: two optical systems, propellant tank, combustion chamber and jet pipe, described two optical systems symmetry respectively are positioned at the outer both sides of combustion chamber, on the both sides of combustion chamber, have the laser incidence window of transparent circle, two optical systems serve as the axle rotation with the laser incidence window, realize receiving all laser beams in the xz plane, when two laser beams converge in the center of same combustion chamber, the propellant that ignition combustion is indoor, from jet pipe, spray, produce thrust forward, reach the purpose of propelling.
Three of technical solution of the present invention: the separation type omnibearing take-over laser booster that adopts the twin-engined structures of dual-beam, comprise: two optical systems, propellant tank, two combustion chambers and two jet pipes, described two optical systems symmetry respectively are positioned at the outer both sides of two combustion chambers side by side, on a side of two combustion chambers, have the laser incidence window of transparent circle, two optical systems serve as the axle rotation with the laser incidence window, to realize receiving all laser beams in the xz plane, when two laser beams converge in two combustion chambers respectively separately during the center, light the propellant in two combustion chambers respectively, produce plasma, and from jet pipe separately, spray, produce thrust forward, reach the purpose of propelling.
The optical system of above-mentioned three schemes constitutes by the parabolic mirror and the plane mirror that are fixed on the support, plane mirror is placed on the center of parabolic mirror and parabolic reflector mirror foci, at the center of plane mirror is turning cylinder, rotating machine drives turning cylinder and rotates around the y axle, laser beam is assembled back reflection to plane mirror through parabolic mirror, and the center of passing S. A. again after plane mirror is assembled enters combustion chamber.
The position vertical with S. A. at an end of support is provided with bob-weight so that optical system barycenter is constant when rotated.
The present invention's advantage compared with prior art is:
(1) optical system is thoroughly separated with push system, and optical system is not subjected to High Temperature High Pressure to advance the influence of air-flow, and the structure of two systems and selection can be distinguished optimal design.
(2) laser beam that can any direction in comprehensive reception space is to adapt to various track conditions.When receiving dual-beam simultaneously, two bundle laser are as long as coplane needn't be parallel to each other.For laser cloth position, relay etc. are provided convenience.During vertical launch, laser beam needn't upwards shine from the aircraft bottom, can be from side direction incident, shown in Fig. 4,5.
