Preferably, described four screw propellers are crossing distribution.

Preferably, described four screw propellers are four engine installations.

Preferably, pipeline is established in described rigidity right-angled crossing support.

Preferably, described master control unit comprises attitude measurement system, motor drive module, main control module, wireless communication module and power module.

Preferably, described four screw propellers can realize the flight of aerial six-freedom degree.

Compared with prior art, the beneficial effects of the utility model are: this four rotor wing unmanned aerial vehicle four screw propellers are little, there is flight safety, control the features such as flexible, and the flight of six-freedom degree can be realized, master control unit comprises the position situation that attitude measurement system, motor drive module, main control module, wireless communication module and power module energy actv. detect four rotor wing unmanned aerial vehicles, realizes long-distance flight, distance control.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1-9, the utility model provides a kind of technical scheme: a kind of four rotor wing unmanned aerial vehicles, at least comprise four screw propellers, rigidity right-angled crossing support and master control unit, described four screw propellers connect firmly by four independently motor drivings on rigidity right-angled crossing bracket institution, and described master control unit organization establishes is in the positive lower end of rigidity right-angled crossing support.

Described four-axle aircraft version as shown in Figure 3, the screw propeller being right-angled crossing by four forms, while screw propeller 1 and screw propeller 3 left-hand revolution, screw propeller 2 and screw propeller 4 clickwise, four-axle aircraft has six-freedom degree in space, can do translation and rotation respectively along X, Y, Z axis.

Described in composition graphs 4: during perpendicular movement, four-axle aircraft is the most also the state of a control the most easily realized, keep the rotating speed of screw propeller 1, screw propeller 2, screw propeller 3, screw propeller 4 identical, the moment of torsion that they produce just can balance mutually, four axles can not rotation in occurred level face, increase the rotating speed of screw propeller gradually, the lift produced when aircraft can overcome self gravity, aircraft just can realize upward vertical movement, when lift is equal with gravity, aircraft realizes hovering, reduce the rotating speed of aircraft, aircraft vertical moves downward, until landing.

Described in composition graphs 5: the rotating speed of screw propeller 1 rises, make the rotating speed of screw propeller 3 decline simultaneously, and the rotating speed of screw propeller 2, screw propeller 4 remains unchanged, in this process, screw propeller 1 and screw propeller 3 knots modification should equal and opposite in directions, when the overbalance moment of torsion that screw propeller 1 and screw propeller 3 produce reaches certain time, aircraft will rotate around y-axis (direction as shown in the figure), in like manner, when the rotating speed of screw propeller 1 declines, the rotating speed of screw propeller 3 rises, and fuselage just rotates to another direction around y-axis, realizes the luffing of aircraft.

Described in composition graphs 6: rolling movement is identical with luffing principle, difference is that one is along Y-axis, and one is along X-axis.

Described in composition graphs 7: two, the screw propeller of four-axle aircraft rotates forward two reversions, when the moment of torsion that their rotating speeds are identical is zero, when four propeller speed are incomplete same, unbalanced reactive torque can cause four rotor wing unmanned aerial vehicles to rotate, when the rotating speed of screw propeller 1 and screw propeller 3 rises, when the rotating speed of screw propeller 2 and screw propeller 4 declines, the reactive torque of screw propeller 1 and screw propeller 3 pairs of fuselages is greater than the reactive torque of screw propeller 2 and screw propeller 4 pairs of fuselages, fuselage just rotates around z-axis under the effect of unnecessary reactive torque, realize the yawing rotation of aircraft, turn to and screw propeller 1, turning to of screw propeller 3 is contrary.

Described in composition graphs 8: increase screw propeller 3 rotating speed, pulling force is increased, corresponding reduction screw propeller 1 rotating speed, pulling force is reduced, keep other two propeller speed constant simultaneously, reactive torque still will keep balance, first have Fig. 5 to know there is inclination to a certain degree in aircraft, thus make rotor thrust produce horizontal component, therefore motion is flown before can realizing aircraft, flight is just in time contrary with flight forward backward, and certainly in Fig. 5 Fig. 6, aircraft also can produce the horizontal motion along x, y-axis while producing pitching, tumbling motion.

Described in composition graphs 9: due to four-axle aircraft symmetrical configuration, tendency is moved and seesawed is that direction is different, and principle is identical.

Described four rotor wing unmanned aerial vehicles can realize the hovering that accuracy rating is 1 meter aloft, can the long-time object observing of actv. dynamic, and manipulation flexibly, this battery module is 10000mAh, can to fly 10km in the flying power be thirty minutes long, maximum speed is 10m/s, the pardon of flying height is 0-1000m, can adaptive temperature scope be-10 °-45 °, its take-off weight 3kg, payload capacity is 1kg, can carry the place that the equipment such as video camera observe the mankind not easily observe in detail.
