The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

In a world dominated by pistons, the rotary engine was something different for motorists. It was the vision of German engineer Felix Wankel, built on the belief that the up-and-down motion of pistons ...

A Wankel engine is a type of rotary engine, but not all rotary engines are Wankel engines. Wrapping your mind around this idea will help you to better understand the similarities as well as the ...

The rotary engine is perhaps one of the most polarizing motors to have ever been commercialized. From its checkered past to its intent to live on as a range extender, the small spinning triangle has ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

Chinese firm Dongan Auto revives the Wankel engine, developing a lightweight prototype aimed at next-gen aerial mobility ...

NASA believes the rotating detonation engine could be the future of deep space travel, and it's getting strong results in prototype testing. Combustion engines are tried and true, and however angry ...
