Description

Atmosphere breathing type laser engine device

Technical field

The present invention relates to motor and remote-wireless energy transmission field, refer in particular to the optical breakdown that superlaser and air interaction after utilize focusing on cause, the plasma explosive blast of formation as thrust keep engine running the laser engine device.

Background technique

Conventional engines uses fuel due to necessary, so its use is subject to the restriction of fuel.For example aircraft or rocket, the consumption of its fuel is very huge, greatly reduces the load of these launch vehicles.And conventional engines can't work under lowpressure or oxygen-free environment.And the burning of fuel can give off a large amount of harmful gases, is unfavorable for environmental protection.A Kantrowitz [A.Kantrowitz.Propulsion to orbit by ground-based lasers[J] .Astronautics and Aeronautics in 1974, 1972, 10 (5): 74-76 has proposed to utilize Trend of Laser Propulsion Technology to launch the concept of grapefruit satellite, its principle is that propulsion system is installed on grapefruit satellite, the core work parts of this propulsion system are one or one group of parabolic, parabolic is used for focusing on the laser beam from ground, make near the air generation plasma blast of focus, thereby reflective surface is formed a deboost.Do a large amount of fundamental researchs about laser propelling aspect about a lot of researchers afterwards, utilized various types of lasers as the energy.When adopting pulse laser as the energy, the effect of laser beam and working medium can produce very large instantaneous acceleration, its running is not steady, and very difficult controlling party to, and such propulsion system can only produce along the axial reaction thrust of parabolic, so its application can be very limited.Domestic Zhou Xinlong has declared a kind of laser power engine patent, the patent No.: 99206057 in 1999.The principle of this utility model patent is that the air that utilizes laser to light in the firing chamber forms negative pressure, thereby comes pushing piston to do manual work by atmospheric pressure.Can at first, form vacuum after the laser combustion air and yet there are no report both at home and abroad, secondly, the thrust of utilizing barometric pressure to produce be large not concerning motor.The people such as Hua Yinqun have declared a kind of without fuel laser engine patent in 2004, the patent No.: 200410014435, its principle is to utilize the high energy pulse Ear Mucosa Treated by He Ne Laser Irradiation at working medium, makes the working medium plasma, and the plasma blast forms the acting of shock wave pushing piston.

In existing technology, the technology drawback of its existence is:

(1) adopt collimated laser beam, because laser beam does not focus on, produce the plasma detonation wave, its specific power must be enough large;

(2) working medium is sealed in the firing chamber, working medium can be recycled, the plasma temperature that produces due to the laser emission working medium is up to 20000k, requires high to the material of its firing chamber;

(3) pulse laser work can only be adopted, continuous laser work can not be adopted;

(4) adopt the contact-type electronic push-button switch to control laser, to guarantee the normal operation of motor, control the working state of laser owing to adopting the wire mode, therefore, can't realize remote or high-altitude transmission laser energy, not bring into play laser as a kind of advantage of outstanding remote transmission energy.

Summary of the invention

The purpose of this invention is to provide and a kind ofly utilize plasma explosive blast that superlaser after focusing and air interact and form as the motor of thrust.

This motor is by the superlaser generator, and sensing system and connecting rod etc. partly consist of.High energy laser beam is after piston end surface focuses on, interact with air, form the plasma explosive blast, the deboost of generation to piston end surface, pass through connecting rod, the rotation that the axial motion of piston is converted into bent axle makes piston produce axial rotation, thus output torque, and sensing system is used for guaranteeing the lasting high-efficiency operation of motor.

In order to realize that piston end surface is designed to parabolic with high energy collimated laser beam reflect focalization.

The collimated laser beam that the high energy laser generator sends is focused on by the parabolic of piston, makes near the air breakdown of focus, produces the plasma explosive blast, thereby reacts on piston face, and piston is formed deboost.The laser that the high energy pulse laser generator sends can be Long Pulse LASER, also can be short-pulse laser.

Nozzle is arranged at a side of cylinder wall, and the effect of nozzle is to make to maintain a certain amount of air in cylinder, and is used for cooling cylinder.

To start function to continue high-efficiency operation in order making, must to guarantee piston when working stroke, the high energy laser generator is in opening state; And when piston returned, laser was in closed condition.The sensing system that is comprised of He-Ne Lasers sensor and reflector group is controlled the working state of superlaser generator.The reflector group is installed on bent axle, is comprised of two anti-mirrors and Dan Fanjing, and reflective surface of two anti-mirrors and the reflective surface of Dan Fanjing are in same plane.The He-Ne Lasers sensor can be launched two bundle He-Ne Lasers, and its distance is greater than the width of two anti-mirrors and Dan Fanjing, causes to guarantee two bundle He-Ne Lasers can not be radiated at simultaneously on same reflector and sends the erroneous trigger signal.When piston was in top dead center, the reflection direction of reflective surface of two anti-mirrors and the reflective surface of Dan Fanjing all pointed to the He-Ne Lasers sensor, and this moment, sensing system received two bundle reflected light, opened the high energy pulse generating device of laser; When piston movement arrives lower dead center, the reflection direction of another reflective surface of two anti-mirrors points to the He-Ne Lasers sensor, and the non-reflecting surface of Dan Fanjing reflector laser not, at this moment, sensing system sends pulse signal to the high energy laser generating means, and the high energy laser generating means stops Emission Lasers.So circulation, thus make motor can continue high-efficiency operation.

Advantage of the present invention is:

1) need not any fuel, as long as air is arranged in environment, can run well equally under anoxic or environment under low pressure, to environment without any pollution;

2) end thrust can be converted to the thrust of any direction by this motor, and can make the running of motor steady;

3) engine device separates with laser beam emitting device, and its separating distance can reach tens kilometers even hundreds of kilometers, can at a distance laser energy be converted into engine power.；

4) engine device is simple in structure, greatly simplified manufacturing technique.
