A turbine is similar to a windmill; it is a very tall tower with two or three blades (叶片) at the top.

The Volt is a twin-engine concept with a hybrid propulsion system that combines gas turbine and battery technology, a tube-shaped body and a truss-braced wing mounted to the top of the aircraft.

To realize high precision control of top pressure, the dynamic mathematical model of top gas pressure recovery turbine (TRT) system was researched.
