In the Russian Federation have tested the laser ignition system of the rocket engine

For the first time in the testing complex "Design Bureau of Chemical Automation" (KBKhA, part of NPO "Energomash") successfully tested the laser ignition system of oxygen-hydrogen fuel liquid rocket engine (LRE), reports press office enterprises.

According to the information, 3 was switched on at the booth of the advanced installation РД0176.ЕЭ2, during which the fuel was ignited by a laser ignition system directly in the combustion chamber. The condition of the equipment materiel after the tests is satisfactory.

These tests were conducted in cooperation with the Research Center. Mv Keldysh during the implementation of the ROC "Creating a new generation of rocket engines and the basic elements of propulsion systems promising means of launching."

According to Viktor Gorokhov, Chief Designer of KBKhA, the introduction of a laser ignition system reduces the engine weight, which is very important for rocket technology, and simplifies the cyclogram of its launch. This, in turn, increases the reliability of the LRE.

He recalled that several years ago the enterprise successfully tested a laser ignition of oxygen-kerosene fuel. The current technology on oxygen-hydrogen is a big step towards the creation of a reliable multiple-actuation engine, which will find its application in promising reusable space-rocket systems.

It is noted that the decision to continue the work in this direction will be made after a detailed analysis of the data obtained during the tests.

Now the small thing is to create an analogue of laser ignition for jet engines and internal combustion engines.

[Vadim237]

There already is - plasma ignition.

I don’t think that the mixture of hydrogen-km and the oxygen problem is set on fire, probably reliability is above all, well, maybe you need to set fire in a certain area and prevent burning failure ...

It’s not difficult to set fire. I remember another lesson from the school chemistry course. A mixture of fluorine and hydrogen is collected in a test tube, and a quartz ultraviolet lamp is turned on next to it, directing light to the test tube. Or a pinch of magnesium is set on fire. The mixture explodes. Oxygen, of course, is not fluorine, but a laser will be more powerful than a lamp.

Any gas or liquid can be ignited. Apparently it really needs to be abnormal for this.

Not any. For the sake of experiment, try lighting one of these: helium, neon, argon, krypton, xenon, radon, or oganeson. If possible, you can safely apply for the "Nobel Prize." Just do not need to give an example of nuclear weapons, a nuclear reaction is not combustion.

[Shahno]

Tuta, probably, meant "ignite" - a reaction with the release of energy (this is me in the footsteps of Zeldovich).

[ALEXXX1983]

Well, the article is not about nuclear topics, but about LRE. So we are only talking about a chemical reaction.

Firstly, do not shift your tasks and goals onto me. And secondly, I said any and this does not require proof. If nuclear reactions in their essence and in the hydro-gas-dynamic flow are not a process of high-potential and high-temperature physical processes, then, I'm sorry I'm not talking about the processes of candle burning. We believe that we are talking about combustion and the technology of how to ignite a hydro-gas-dynamic flow at its hyper-high speed and we mean a process that has applied value.
I don’t need to prove to myself what is obvious as a clear day. We are talking about technology, which is the foundation of the future in aviation and other areas of energy. And for this, you just need to understand why modern aircraft engines and rocket engines have also reached the top of their modernization and development. Next, you just need to switch to a new concept of organization and the process of what is happening in the engine, and most importantly, switch to new methods of analyzing such processes

The question is not in the subject matter, but in the level of analysis of what allows both to understand processes and solve applied problems. Therefore, it is analysis at the level of constructing a model of complex and high-potential interactions of magnetic processes that is the basis for solving problems. Magnetic. Power processes is a deeper level than analysis at the level of nuclear processes. And if you believe that in a liquid or gas-dynamic processes there is no dimension and other processes of interaction of the components, then I'm sorry.

[Beltasir matyagu]

Well, artillery has already begun to use microwave detonation instead of an ancient detonator. Now we got to laser ignition

Gridasov. You will forgive, but from topic to topic drag the need for analysis of magnetic processes and other unscientific nonsense, and screw it to this entire dimension to the heap. What dimension are we talking about? Topological? Physical quantities? Fractal?
Well, maybe it’s enough to fool around already, and, Gridasov?
Well, either post links to the mat. apparatus for familiarization. Although what am I talking about ..
