AeroSpace Laser Jet Engines (LJE)

Laser jet engines (LJE) present a new class of engines suitable for application in design of such vehicles as high-altitude robot planes, carrier rockets and spacecrafts. LJE can be used to transfer a spacecraft from a low near-earth orbit onto a geostationary orbit, to correct the spacecraft orbit and its orientation.

An idea to apply the laser propulsion in aircraft is under development since the early 70th. The main peculiarity and one of the advantages of the laser propulsion as compared to the conventional methods of jet propulsion generation is that it is drawn owing to energy of a distant source. This results in small weight and allows one to increase considerably the useful carrying capacity of a vehicle.

The laser propulsion features a high specific impulse as compared with the conventional jet propulsion at sufficiently high values of propulsion.

An aerospace laser jet engine (ALJE) is under development in FGUP NIIKI OEP. Patent of the RF N2266420 is hold. Experiments on demonstration flight of a vehicle equipped with the aerospace laser jet engine prototype have been successfully carried out.



Demonstration experiments with the prototype with total weight of 150 g moving along an inclined path showed the following performances:

Max propulsion - 1.5 N
Max vehicle speed - 5 m/s
Max vehicle acceleration - 5 m/s2
Max specific recoil momentum - 25 dyn/W at average power of laser radiation of 5 kW


At present the following works are conducted in FGUP NIIKI OEP:

Development of jet nozzles and optical concentrators of laser radiation
Research into physical-chemical processes in interaction between laser radiation and different matters with СНО chemical composition
Studies on gas-dynamic processes of propulsion generation in laser-chemical jet engines

мне нравится эта идея

[5188510]

Можно также использовать луч электронов, это более эффективно, т.к.

- во первых электронные пушки гораздо мощнее лазера;

- во вторых лучом электронов можно управлять при помощи электромагнитов.

[5188510]

дополнение: в принципе можно двигатьяся и навстречу лучу, но тогда нужна немного другая конструкция двигателя

[danilkusm]

лазерный луч толкает ту штуку штоли?!

[5188510]

YES да

[5188510]

идея в том, что-б передать энергию на расстоянии и не брать с собой топливо.

так можно делать космические трассы, где Вы "прыгаете" кораблем на луч и летите себе до пункта назначения, как типа по хайвею (шоссе), а сама питающая электростанция на земле или на другой планете!...

Cool!

[adelle0001]

parang movie lang ah!

[khyron6]

Sounds like Buck Rogers or Flash Gordon spaceships.

[MichaelCox]

So the Russians have been working on this concept too, eh?

Как интересна...

[unambitious]

Interesting... is it a russian project? is it moving laterally or up? Thanks.

[AnselmoFanZero]

Is there a more ineffcient way to propel a dreidel?

[AnselmoFanZero]

Pulslasers are very inefficient...not made for propulsion.

[UndeniableTrue1]

Hot Pursuit is active, everybody will be found, nobody will get away with anything, not even one hair or dna.

Russian. Damn commies.
