Chernogorov’s air propulsion device is designed for passenger airliners as a reliable and efficient propulsion device. It is powered by a powertrain shaft, which may preferably be an aircraft electric engine. It can operate reliably at altitudes up to 50 km from sea level. In terms of developed thrust, it surpasses any turbofan engine of equivalent mass. Significantly more economical than the best turbofan engines. It is structurally simpler than any turbofan engine. Easy to maintain. The higher the airliner’s flight speed, the greater the thrust of an air propulsion system. She is not afraid of getting such birds as gulls, crows, pigeons inside, since the propeller can be periodically blown by a stream of air from a fan at the command of a pilot. In addition to the traction fan, the air propulsion device has a traction rotor, which creates traction along the axis of rotation of a much larger value than the traction fan at the same speed, since both the fan and rotor sit on the same shaft. Such a shaft may be an electric motor shaft with support and thrust bearings common to the electric motor and air propulsion. Not a single designer in the entire 130-year history of aviation development has come up with such an air propulsion device.
