Swing propulsion aircraft. At present, there are two ways of propelling all aircraft in the world, one is propeller, the other is jet. Oscillatory propulsion is a new form of propulsion, based on thebionic principles of birds and fish, which move forward by means of oscillation. This new type of propulsion will greatly reduce production costs and energy consumption, especially in reducing noise,the noise of high-grade automotive engines itself is very small, and the screen is open in the fuselage, can be called the world's aircraft without noise. The swing propulsion aircraft will play an important role in the field of light aircraft.
