Fixed wing aircraft.
A kind of fixed wing aircraft with flapping wing, including fuselage, empennage, left wing, right flank, power set, left flapping wing device and
Right flapping wing device.Empennage is located at afterbody；Left wing and right flank are arranged symmetrically in the left and right sides of fuselage；It is equal in left wing and right flank
Equipped with an aperture；Power set are located at front end or left wing and each arrangement one of right flank of fuselage, provide and fly for fixed wing aircraft
Action edge.It is furnished with flying control equipment, airborne equipment and power-supply device in fuselage, flying control equipment carries out flight attitude control to aircraft
System, airborne equipment include various flight instrumentation instrument, capture apparatus and navigation equipments.Left flapping wing device and right flapping wing device structure
It is identical, in left wing and the aperture of right flank that they are symmetrically distributed in.
Right flapping wing device includes fixed frame, engine, main shaft, gear wheel, pivoted arm, the first small pulley, the second small pulley, the
One big belt wheel, the second big belt wheel, the first belt, the second belt, the first axis of traction, the second axis of traction, the first fixed frame, second are consolidated
Determine frame, the first blade and the second blade.Fixed frame is installed on the wing at the aperture position of right flank；Main shaft is installed on by bearing
On fixed frame；Gear wheel is installed on main shaft；It is fixed in the middle part of pivoted arm on main shaft；The power of engine is passed by gear structure
It is sent to gear wheel, main shaft drives pivoted arm to rotate during bull gear drive；First small pulley and the second small band wheel construction are identical；First is small
Belt wheel and the second small pulley are installed on main shaft by bearing, and the first small pulley and the second small pulley do not rotate together with main shaft；
First axis of traction and the second traction axle construction are identical, they are separately mounted to the both ends of pivoted arm by bearing；First big belt wheel and
Second largest pulley structure is identical；First big belt wheel be installed on the first axis of traction on, the first big belt wheel rotate when the first axis of traction with
Rotation；Second big belt wheel is installed on the second axis of traction, and the second axis of traction is with rotation when the second big belt wheel rotates；First skin
