俄脉冲爆震发动机测试成功 能让飞机以10倍音速飞行

【俄脉冲爆震发动机测试成功 能让飞机以10倍音速飞行】俄塔社27日报道,俄罗斯率先成功进行新一代脉冲爆震发动机测试,这种革命性的发动机在燃烧室内直接利用爆震燃烧产生的爆震波来压缩气体进而产生动力,具有结构简单、推重比高、成本低廉等特点,也被认为是21世纪最有潜力的空天动力项目。发动机不仅适用于航天领域,也能装载在飞机上,理论上可以让飞机的最大速度达到10倍音速。

Scientists with the Russian Advanced Research Foundation (FPI) conducted tests through July and August, RT reports, and has now revealed their achievements on the group’s website.

According to the FPI, this marks ‘the world’s first full-size pulse-detonation rocket engine demonstrator.’
This type of system uses detonation waves to combust the fuel and oxidizer, and the researchers say it would rely on clean fuel – an oxygen-kerosene pairing.

‘We took up the challenge – to prove the possibility to create a detonation in oxygen-kerosene rocket engines,’ Igor Denisov, the FPI’s deputy director said in comments on the successful tests, RT reports.
‘And now we can firmly say that this is possible, and we know how to do it.’
The project was launched in 2014, backed by Energomash.
And, Russia isn’t the only country that has been interested in this type of technology.

According to RT, the US is involved in developing pulse-detonation engines as well.
The US tested a pulse-detonation engine in a plane back in January 2008 through the US Air Force Research Laboratory.
The FPI claims the liquid fuel engines used by rockets today have reached their full potential, and the new system could push capabilities much farther.
‘The experimental studies have clearly confirmed the theoretical possibility of creating a national PDRE for a new generation of missile technology,’ said Boris Satovsky, the chief of the project, RT reports.
‘Many leading countries are involve in the development of detonation engines, but no one has so far yielded any serious results.’
