Abstract

The utility model relates to an air-bag type movement aircraft which is composed of an air bag, a power motor, rotary wings and a driving rod, wherein the two rotary wings of the movement aircraft are driven by the same driving rod and the rotary wings have equal rotary speed and opposite directions. Generated inverse torsional force moments are counteracted with each other, and the mechanical energy of the motor is converted into lifting force fully. As the movement aircraft is designed by low gravity center, after the movement aircraft takes off, the utility model can balance any disturbance from the transverse side and the utility model has good pneumatic performance. Simultaneously, the normal work of the motor, a battery and the rotary wings can not be influenced by the leakage of the air bag. Thereby, the flying stability and the safety of a user are guaranteed.

Description

Gasbag-type motion aircraft

The utility model relates to a kind of model plane gasbag-type motion aircraft

At present, model helicopter is a power with internal combustion engine and motor, produce lift by main rotor, same with the anti-torsional moment that tail slurry comes the balance main rotor to be produced, and control its heading, control the pitching of main rotor in operation with remote controller, the pitch of main rotor, the power output of motor, the pitch of tail-rotor is made helicopter and is hovered, rise, descend, various motions such as spiral, because the cost height of helicopter, the site requirements strictness, huge rotor rotates the danger that is brought at a high speed and can not be ignored, at the deficiency that exists in the present model plane, and in conjunction with the characteristics of model plane, the utility model has designed a kind of gasbag-type motion aircraft on the basis of ZL00258825.0.

The utility model purpose is, designed a kind of gasbag-type motion aircraft, it is made up of air bag, power motor, rotor, drive link etc., rotor in this motion aircraft is one group by two and forms, its rotating speed is identical, direction is opposite, and the anti-torsional moment that is produced is cancelled out each other, and the mechanical energy of motor all is converted into lift.In order to solve power motor thrust-weight ratio problem of smaller, the utility model designs at the speed reducing ratio of travelling gear, satisfied ceiling altitude respectively, requirement when the longest flight time and motion flying saucer ground proximity are imitated flight with carrying out makes power motor and battery bring into play maximum usefulness.But this motion aircraft balance is from any disturbance of horizontal side and have good pneumatic property, can not influence simultaneously the operate as normal of motor and rotor because of the accidental gas leakage of air bag, thereby the stability of flight and user's security have been guaranteed, this motion aircraft is easy to assembly, cost is low, the safety coefficient height can be done vertical lifting, decline, motions such as straight line or curve.

A kind of gasbag-type motion aircraft described in the utility model, it is made up of air bag, power motor, rotor, drive link etc., and this aircraft includes two air flue aircraft or four air flue aircraft; Air flue middle gear case (9) in air bag (1) is connected with drive link (10) in the drum (7) by sleeve pipe (8), drive link (10) is connected with travelling gear (11), drum (7) bucket wall is close to air bag (1) inwall, gear in the gear-box (9) is fixing with rotor or propeller (6) by axle, power motor (16) fixing in the drum (7) is connected with battery case (15), does not have automatic power-off switch (14) on battery case; Gear (12) on the power motor (16) and travelling gear (11) interlock mutually are provided with rotary switch (13) and undercarriage (17) on battery case (15).Air flue in the air bag (1) can be two, also can be four, and therefore fixing rotor or propeller can also can be four for two on each air flue.Air bag in this aircraft (1) can adopt the high-strength polyethylene material to make, and can also adopt the light plastic material substitution.

Gasbag-type motion aircraft described in the utility model, it is made up of air bag, power motor, rotor, drive link etc., and this aircraft comprises two air flue aircraft or four air flue aircraft; In the gasbag-type motion aircraft of two rotors or propeller, air flue (2) in air bag (1), (3) middle gear case (9) are connected with drive link (10) in the drum (7) by sleeve pipe (8), drum (7) bucket wall is close to air bag (1) inwall, gear in the gear-box (9) is fixing with rotor or propeller (6) by axle, the bottom of drum (7) is fixed with battery case (15), power motor (16) fixing in its barrel is connected with battery case (15), is provided with automatic power-off switch (14) on battery case; Gear (11) on the power motor (16) and travelling gear (12) interlock mutually, travelling gear (12) is fixed on the drive link (17), because two rotors or propeller gasbag-type aircraft are by same drive link transmission, rotating speed is identical, direction is opposite, the anti-torsional moment that is produced is cancelled out each other, and the mechanical energy of motor all is converted into lift.In the gasbag-type motion aircraft of four rotors or propeller, air flue (2) in air bag (1), (3), (4), (5) middle gear case (9) is connected by the interior drive link (10) of sleeve pipe (8) and drum (7), drum (7) bucket wall is close to air bag (1) inwall, gear in the gear-box (9) is fixing by axle and rotor (6), the bottom of drum (7) is fixed with battery case (15), power motor (16) fixing in its barrel is connected with battery case (15), on battery case (15), be provided with automatic power-off switch (14), air flue (2), (5) two rotors in or propeller are by same drive link transmission, rotating speed is identical, direction is identical, air flue (3), (4) two rotors in or propeller are by same drive link transmission, rotating speed is identical, direction is identical, air flue (2), (5) two rotors in or propeller rotation direction and air flue (3), (4) two rotors in or propeller direction of rotation, two rotors that per like this two rotation directions are identical or the anti-torsional moment that propeller produced form a rotating torque in the center, the direction of these two rotating torques is opposite, when these two rotating torque sizes are identical, cancel out each other, the mechanical energy of motor all is converted into lift, the motion aircraft does not rotate, when two rotating torques size is unequal, then most of mechanical energy of motor is converted into lift, has only the sub-fraction moment that rotates that the operation aircraft is rotated.

In use, at first air bag is inflated, the regulating tooth roller box, change the yawing moment of rotor or propeller, open rotary switch, power motor is started working, because the power motor gear drives the both sides rotor with the interlock of travelling gear or propeller is rotated with opposite direction, 3-4 after second the motion aircraft produce enough lift and can take off, according to predefined action flight, along with after electric energy exhausts the flight that the motion aircraft carries out certain hour, slowly drop to ground, because this motion aircraft is the centre of gravity design, after the motion aircraft takeoff, but balance is from any disturbance of horizontal side, and has good pneumatic property, can not influence motor because of air bag gas leakage simultaneously, battery, the operate as normal of rotor.Thereby the stability of its flight and user's security have been guaranteed.
