Low-resistance synchronous direct-acting type double-flapping-wing aircraft

The invention relates to the field of flapping wing type aircrafts and flying robots, in particular to a low-resistance synchronous direct-acting type double-flapping-wing aircraft. The double-flapping-wing aircraft comprises flapping wings, slideways, connecting pieces, a first speed reducer, a stepping motor, a transmission mechanism, a second speed reducer, motors and a machine body frame, wherein the two slideways in the vertical direction are symmetrically installed and fixed on two sides of the machine body frame; the two connecting pieces are respectively connected to the two slidewaysin a sliding manner; the two flapping wings are respectively connected to the two connecting pieces and can rotate relatively; the flapping wing comprises a flapping wing frame and a rotatable blade arranged in the flapping wing frame; a torsional spring is also arranged in the flapping wing frame and is used for resetting the blade; the transmission mechanism is connected to the two connecting pieces; the motors arranged
