Abstract
A head propeller of the flying vehicle compresses incoming flow at a vehicle head inside an upper duct to a lower duct through an air suction channel. A portion of airflow is compressed to the lower duct through the air suction channel under an action of a guide plate and a vehicle body propeller. A bottom propeller of the flying vehicle compresses an airflow into pressure bins of the lower duct at a lower portion through the air suction channel. A sealing state of the pressure bins of the lower duct is destroyed. High-pressure airflow inside the lower duct is jetted out from an air outlet channel to the upper duct. A tail propeller guides the airflow to the tail portion of the vehicle body. The upper duct and the lower duct are constructed inside the pipeline, so a running resistance of the flying vehicle is reduced.
