Internal combustion engines are a relatively new development in terms of human history. A lot of people still alive today ...

One of the rotary engine's biggest champions, AIE has been advancing rotary design since 2012. Its latest release shows that Wankel engines can be a perfect fit for compact, power-demanding ...

Wankel also noticed the radial engines that were already used by aviation. These were created by Felix Millet in 1888 and entered production in 1900. But, unfortunately, that type of engine had ...

3W-International exhibited the new 3W-180 SRE hybrid Wankel engine at this year's Xponential early in the summer of 2017. ... This additional power can be drawn upon when starting a helicopter or ...

The Wankel engine never really fulfilled its promises and hopes, though over its history over 25 major automobile, motorcycle, tractor, and aircraft companies, ranging from Suzuki to Rolls-Royce ...

This “inside-out” approach to the Wankel rotary engine is a key differentiator. ... “On a flight, the pilot used the inefficient APU to burn fuel and reduce the aircraft’s weight.

But there is another rotary engine that has a prior claim to the name, and it can be found as the power unit for many early-twentieth-century aircraft. In these rotary engines the cylinders are ...

The engine's main advantage is a greater power density than a Wankel can achieve because a more-balanced design allows the motor to rev higher—so says Peter King, one of two partners at REDA.

The host of this video describes the tiny motor as a "Wankel rotary model aircraft engine," and while it looks very much like a toy, there's nothing toy-like about the classic, rotary-smooth, high ...

The Wankel rotary engine is known for its troubled life in the mainstream automotive industry, its high power-to-weight ratio, and the intoxicating buzz it makes at full tilt. Popular with die-hard… ...

We've written a few times before about the fascinating LiquidPiston rotary engine. It's not a Wankel – indeed, it's closer to an inside-out Wankel – and with only two moving parts, it's able ...

LiquidPiston's X-Engine, which we've covered previously and is helping the Air Force develop vertical takeoff and landing concepts, can now run on hydrogen gas.
