Aircraft propulsion system comprising four engines with pusher propellers
View Patent ↗An aircraft propulsion system includes four engines with pusher propellers. The engines are mounted in pairs on the wings of the aircraft and the respective directions of rotation thereof, when viewing the engines from the rear of the aircraft from left to right, are: (1) the clockwise direction, (2) the counterclockwise direction, (3) the clockwise direction, and (4) the counterclockwise direction.
1. A propulsion system for an aircraft, comprising:
four engines with pusher propellers, the engines being mounted in pairs on the wings of the aircraft and each having a specific direction of rotation, wherein:
the respective direction of rotation of said four engines when viewing said engines from the rear of the aircraft is, from left to right:
the clockwise direction;
the counterclockwise direction;
the clockwise direction; and
the counterclockwise direction,
the engines are mounted in a line along the wings from one side of the aircraft to the other,
the two engines on the left side of the aircraft, viewed from the rear, are contra-rotating and air is concentrated between these two engines so as to guide the air flow in the direction of a tail fin of the aircraft,
the two engines on the right side of the aircraft, viewed from the rear, are contra-rotating and air is concentrated between these two engines so as to guide the air flow in the direction of the tail fin of the aircraft, and
the tail fin is exposed on both sides to a convergent air flow as a result of the pair of contra-rotating engines on each side of the aircraft.
