Description
【Technical field】
The present invention relates to a kind of engine, and in particular to a kind of engine that thrust is produced using laser.
【Background technology】
Known, satellite is when space works, due to can gradually be dropped by earth rarefied air drag effects, orbit altitude
It is low, eventually crash into atmosphere and burn.
In order to solve influence of the earth rarefied air resistance to satellite orbit, satellite can use compressed gas as fuel,
Using compressed gas spray caused by thrust maintain satellite orbital altitude.Wherein compressed gas is then needed by high pressure storing
Case is stored, and then causes the drawbacks such as cost height, security difference.Thrust, compressed gas are produced in addition, being sprayed using compressed gas
Body jet velocity is relatively low, therefore fuel utilization efficiency is relatively low, and in the case where fuel mass is certain, the lifetime of satellite can be because of fuel profit
It is low with efficiency and shorten etc..
【The content of the invention】
It is insufficient to overcome present in background technology, the invention provides a kind of engine that thrust is produced using laser,
The present invention without using compressed gas does fuel, eliminates high pressure material storing box, and reliability is higher, the present invention have it is safe, into
The characteristics of this is low, fuel availability is high.
To realize goal of the invention as described above, the present invention uses technical scheme as described below：
It is a kind of using laser produce thrust engine, including power supply, laser generator, engine body, fuel and swash
Light outgoing mirror, the engine body are drum-shaped structure, the lateral surface of engine body blind end be respectively equipped with power supply and
Laser generator, the power supply are provided with fuel in the bucket bottom of engine body, started by cable connection laser generator
The openend of machine body is provided with laser outgoing mirror, and the minute surface of laser outgoing mirror corresponds to fuel, and laser outgoing mirror is connected by optical fiber
Laser generator forms the described engine that thrust is produced using laser.
The described engine that thrust is produced using laser, the fuel are the metal material for having to laser high-absorbility
Material.
The described engine that thrust is produced using laser, the metal material is iron or lead.
The described engine that thrust is produced using laser, the power supply is high-energy-density battery.
The described engine that thrust is produced using laser, the laser generator is optical-fiber laser generator.
Using technical scheme as described above, the present invention has superiority as described below：
A kind of engine that thrust is produced using laser of the present invention, the present invention do fuel without using compressed gas,
High pressure material storing box is eliminated, reliability is higher, and further, the generation of motor power is that laser beam is radiated on fuel, fuel
Gasification is heated in laser-irradiated domain moment, the injection stream of fuel gasification sprays at a high speed from fuel surface, because vaporising fuel from
Fuel surface similar blast when spraying, jet velocity is high, therefore fuel utilization efficiency is higher etc., and the present invention has security
High, the characteristics of cost is low, fuel availability is high.
