The invention discloses a double-engine rotary horizontal flapping wing air vehicle belonging to the technical field of aviation. The double-engine rotary horizontal flapping wing air vehicle comprises an air vehicle body, a rear wing, a left rotary horizontal flapping wing device, a right rotary horizontal flapping wing device and an undercarriage, wherein the left rotary horizontal flapping wing device and the right rotary horizontal flapping wing device are same in structure, parameter and working principle and are symmetrically arranged; the rear wing is used for controlling the pitching and steering flight attitudes; the right rotary horizontal flapping wing device comprises a main shaft, a rotating arm, a first wing shaft, a second wing shaft, a first wing blade, a second wing blade, a front synchronous belt driving mechanism and a rear synchronous belt driving mechanism; a front central synchronizing wheel and a rear central synchronizing wheel are coaxially and fixedly arranged; the transmission ratio of the front central synchronizing wheel to a front wing synchronizing wheel is 1:1, and the transmission ratio of the rear central synchronizing wheel to a rear wing synchronizing wheel is also 1:1; the front edges of both the wing blades are always in a horizontal position; and both the wing blades cannot generate components in the spanwise direction in the vertically-flapping process and are relatively high in efficiency. The double-engine rotary horizontal flapping wing air vehicle is used for tasks such as aerial photography, geographic measurement, agricultural and forestry works, military reconnaissance as well as rescue and relief.
