Abstract
An aircraft may have a fuselage, a left wing extending from the fuselage, a right wing extending from the fuselage, a tail section extending from a rear portion of the fuselage, and a first engine and a second engine operably connected by a common driveshaft, wherein the first and second engines are configured for freewheeling such that if one of the first and second engines loses power the other of the first and second engines continues to power the aircraft.
Claims15
An aircraft comprising:
- a fuselage having a longitudinal axis;
- a left wing extending from said fuselage;
- a right wing extending from said fuselage;
- a tail section extending from a rear portion of said fuselage;
- a first engine disposed in said fuselage;
- a second engine disposed in said fuselage;
- said first and second engines being operably connected to a first common driveshaft traversing through said first and second engines and having an axis of rotation oriented transverse to said longitudinal axis of said fuselage;
- a first propeller rotatably mounted to said left wing and operably connected to said first common driveshaft;
- and
- a second propeller rotatably mounted to said right wing and operably connected to said first common driveshaft;
- wherein said first and second engines are configured for freewheeling such that if one of said first and second engines loses power the other of said first and second engines continues to power said first and second propellers.
