Often pair of described birotor is by the upper motor of rotor in upper rotor, lower rotor, driving, drives the base of the lower motor of lower rotor and the upper motor of connection and lower motor to form.The line of centers of the S. A. of often pair of two-spool upper motor and lower motor point-blank.Often pair of two-spool upper motor becomes an equal angle with rotating shaft center's line of lower motor with the geometric center lines place interplanar of described four hold-down arms, and angle is greater than 0 degree and is less than 90 degree.Adjacent two is contrary to two-spool upper rotor wing rotation direction, and adjacent two is contrary to two-spool lower rotor hand of rotation.On diagonal line, two is coplanar or parallel to the plane of rotation of two-spool upper rotor, on diagonal line two two-spool lower rotor is revolved turn co-planar or parallel.Often pair two-spool upper rotor is parallel with the plane of rotation of lower rotor, hand of rotation is contrary.Rotating shaft center's line of the often pair of two-spool upper motor and lower motor is with to be connected this vertical to the geometric center lines of two-spool hold-down arm.

The beneficial effects of the utility model are:

Compared to prior art, the on-plane surface four arm eight-rotary wing aircraft that the utility model provides, often pair of two-spool upper and lower two rotors are driven by upper and lower motor respectively, control the rotative speed of upper and lower two rotors of each birotor, making that its torque is equal, direction is contrary, is zero to the conjunction moment of torsion of body, in addition, when aircraft flight, two rotors of often pair of birotor positive and negative rotation eliminate the gyroscope interference to body.What the four pairs of two-spool electric machine rotational axis line of centerss were equal with four that the geometric center lines place interplanar of described four hold-down arms becomes be greater than, and 0 degree of angle being less than 90 degree makes to go off course is provided by lift, and solving plane four rotor and coaxial eight rotors needs and the shortcoming of control torque deficiency slow by anti-twisted Torque Control yaw response.

What on-plane surface four arm eight-rotary wing aircraft of the present utility model adopted two-spoolly to be compared with the power system that rotor forms by upper and lower two groups of motors that the power system volume utilization that one group of motor of the plane of the multi-rotor aerocraft of planar structure and rotor form is high, lift density is high, has larger load-carrying ability and longer flight time under equal volume.
