Recently, the Russian Advanced Research Foundation (FPI) announced that Russia has successfully tested a new generation of liquid fuel pulse detonation engines. This success represents "the future of space travel."
Pulse detonation engine is a new concept engine. The engine uses a detonation wave generated by knocking combustion to compress gas and generate power. Compared with conventional engines, the pulse detonation engine eliminates components such as compressors and turbines. It has the characteristics of simple structure, high thrust-to-weight ratio, and low cost, and is considered to be "the most potential space-power project in the 21st century."
Founded in 2012, FPI is currently the only research organization in Russia that specializes in the research of advanced defense technologies. The said: This test was jointly completed by the Russian liquid pulse detonation engine specialized laboratory, the Russian Academy of Sciences Noval Siberia Lavritiyav fluid dynamics research institute, and the Moscow Aviation Academy. The fuel used for testing was liquid oxygen and kerosene, which uses a high degree of thermal efficiency to allow the spacecraft to perform more powerful functions. This engine can make the rocket more loaded and can reduce the cost of entering the rail load.
According to foreign media RT, the project started in 2014 and was supported by the Russian energy engineering company Energomash. Russian scientists successfully conducted several tests on this new type of engine from July to August. The tests used fuels such as liquid oxygen and kerosene. The project leader Boris Satovsky stated:
The test successfully generated detonation waves of different energies and balanced vibration and shock loads. Experimental studies have clearly demonstrated the technical feasibility of this new engine. Now Russia's task on the data research and simulation phase has ended and the focus of the work shifts to the ignition test phase. Many countries have participated in the research of pulsed engines, but so far, only we have achieved success, which will greatly promote the development of a new generation of launch technology.
Igor Denisov, vice president of FPI, said:
We met the challenge and proved the possibility of creating a pulse detonation engine.
In fact, Russia is not the only country interested in such technology. According to RT reports: The United States also joined the pulse detonation engine early. In January 2008, the U.S. Air Force Research Laboratory tested pulse detonation engines on the back of an aircraft.
The FPI stated that the liquid fuel engine used by the rocket has already exerted its maximum potential. The idea of ​​using a knock combustion mode is the most cost-effective fuel consumption mode from a thermodynamic point of view. It allows the engine's capabilities to be further developed.
It is reported that the engine is not only suitable for the aerospace field, but also can be loaded on the aircraft. Theoretically, the maximum speed of the aircraft can reach 10 times the speed of sound. Scientists all over the world have always dreamed that in the future, aircraft equipped with pulse detonation engines can easily shuttle between heaven and earth. The pulse detonation engine's high combustion efficiency makes it ideal for use as a power source for patrol aircraft, unmanned reconnaissance aircraft, and other long-haul aircraft.
However, according to the "Global Times" report: Although Russia successfully completed this test marks the great progress in the aerospace field, but we only understand the basic principles of pulse detonation engine, to really apply and achieve development is also facing difficulties. For example, when a detonation burns, it will generate strong vibrations and huge noise. If this problem is not solved, the pulse detonation engine will be difficult to use for manned commercial flights. In addition, the research on this kind of revolutionary engine is still in an early stage in various countries. The shape of the engine combustion chamber and the design of the nozzle are still being explored.
