Continuing high fuel costs and growing environmental pressures could inject new urgency into development of pulse-detonation engine (PDE) technology for wider commercial applications, rather than just ...

Pratt & Whitney’s successful PDE combustor trials could lead to demonstrator getting airborne by 2008 Pratt & Whitney plans to launch a new phase of collaborative research work with NASA and the US ...

An experimental pulse-detonation-powered aircraft should begin test flights next month at Mojave, Calif., now that the FAA has issued it an airworthiness certificate. Powered by a pulse detonation ...

Various forms of unsteady or pulse detonation combustion in the future could feature turbine-based combined cycle (TBCC) engine concepts that form part of NASA’s ongoing studies into highly reliable, ...

Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A team at Tsinghua University in Beijing created a new design known as the ...

Engines that convert chemical energy from fuel into kinetic energy via explosive detonation, rather than slower deflagration combustion as seen in typical internal combustion engines. Categories ...

WEST LAFAYETTE, Ind. – Researchers at Purdue University have developed new combustion technology that can shrink the size of engines and eliminates the need for them to be round in shape. The novel ...

Explosions get you much more bang from your fuel buck than combustion – if your engine can withstand them. NASA believes the rotating detonation engine could be the future of deep space travel, and it ...

A.At the risk of oversimplification, here is the relationship between cylinder pressure conditions and time in a normal combustion process vs. detonation. Note that the rate of pressure rise vs. time ...
