quasiturbine 

The Quasiturbine (Qurbine) is a no crankshaft rotary engine having a 4 faces articulated rotor with a free and accessible centre, rotating without vibration nor dead time, and producing a strong torque at low RPM under a variety of modes and fuels. The Quasiturbine is also an optimization theory for extremely compact and efficient engine concepts.

The Quasiturbine's high power-to-weight ratio makes it exceptionally suitable for aircraft engine and its no-vibration attributes make it suitable for use in, for example: chainsaws, powered parachutes or snowmobiles. Variations on the basic Quasiturbine design also have applications as air compressors and as supercharger.
