Embodiment Construction

[0020] control figure 1 The realization process of the present invention is described.

[0021] The double-rotor unmanned helicopter includes: fuselage, 2 crossed rotors, rotor main shafts 1 and 5 respectively connected to the two crossed rotors, main shaft gears 2 and 6 respectively connected to the two rotor main shafts 1 and 5, respectively connected to Main shaft gears 2, 6 are connected to the power source, and the intersecting state of the crossed rotors is: when one rotor is perpendicular to the longitudinal direction of the fuselage, and the other rotor is parallel to the longitudinal direction of the fuselage, the two rotors are just vertical; it also includes: a synchronous The device is guaranteed by the fixed meshing of two main shaft gears; the synchronous device structure includes: a pair of spiral bevel teeth 3, 7, connected to two main shaft gears 2, 6; a pair of vertical support plates 4, 8, and vertical support The riser 9 to which the plates 4, 8 are conne...

Abstract

The invention relates to a rotor type unmanned helicopter, and further relates to a two-rotor unmanned helicopter which aims to solve the simultaneous problem of a rotor spindle of the existing two-rotor unmanned helicopter in the process of flying. The technical scheme includes that the two-rotor unmanned helicopter comprises a machine body, two crossed rotors, the rotor spindle, spindle gears and a power source, wherein the spindle gears are respectively connected with the rotor spindle. The crossed state of the crossed rotors is that when a rotor is longitudinally vertical to the machine body and the other rotor is longitudinal parallel to the machine body, the two rotors are perpendicular to each other exactly. The two-rotor unmanned helicopter further comprises a simultaneous device. Compared with the prior art, the two-rotor unmanned helicopter has the advantages that due to the fact that simultaneous device is meshed in a mechanical mode, the coordination of the rotation of the two rotors are ensured, and the two rotors can not collide with each other when working.

Description

technical field [0001] The invention relates to a rotary-wing unmanned helicopter, and further relates to a double-rotor unmanned helicopter. Background technique [0002] as attached Figure 2-6 As shown, the rotor layout of the helicopter mainly includes single-rotor tail rotor type, double-rotor tandem type, double-rotor horizontal type, double-rotor coaxial type, double-rotor crossed type, etc. The layout of the rotor has a great influence on the helicopter. Different layout forms and structures are also different, which will greatly change the performance of the helicopter. The double-rotor cross type is also called "cross type". The "cross type" is the same as the "horizontal type". The two rotors are exactly the same, arranged left and right along the horizontal direction of the body, but their axes are crossed in a "v" shape and rotate in reverse. Its distinctive feature is that the two rotors are not parallel and tilt outward respectively. The biggest advantage o...
