A group of Chinese researchers have created the world’s first hypersonic detonation wave engine that can propel a plane to Mach 9 (11,113.2 kilometers per hour, approx.). The South China Morning Post (SCMP) reports that the engine underwent a series of tests in the JF-12 Hypersonic Shock Tunnel in Beijing (China), guaranteed successful result,
SCMP notes that the tests were conducted earlier this year, and researchers published technical data on the kerosene engine in a report in the Journal of Experiments in Fluid Mechanics.
Compared to other hypersonic engines, a detonation engine can work effectively with more power, as the blast wave triggers a succession of rapid explosions and release a lot of energy compared to conventional combustion.
With regard to operations, Uses a series of shock waves To propel the aircraft by injecting fuel into a ring-shaped channel, and once ignited, the shock wave creates a cascade of self-propelled explosions, igniting the next round of fuel.
such innovation Uses a jet fuel called ‘RP-3’It required ten times more firing chamber than a hydrogen-powered engine, and unfortunately, the scientists had problems with ignition (it is hard to ignite kerosene at speed and with hot air).
Currently, long-range flights are a mission impossible for hypersonic aircraft, and researchers working on this technology claim that reducing Construction and operating costs remain a major problem.
