The state of flight that should invent a kind of high strength rotary flapping wing aircraft is below described further this invention.
Take off: start main motor, drive anticlockwise flapping wing 5 and right rotation flapping wing 6 to flutter, utilize control system 4 to make tail undercarriage 7 blade plane of rotations neither be tilted to the left and also not be tilted to the right in left and right balance position simultaneously, and adjust the rotating speed of tail undercarriage 7, make making a concerted effort upwards of anticlockwise flapping wing 5, right rotation flapping wing 6 and tail undercarriage 7 generations, when this makes a concerted effort to be greater than body weight, this high strength rotary flapping wing aircraft vertically goes up to the air.
Before fly: after taking off, accelerate the rotating speed of tail undercarriage 7, afterbody raised, suitably improve the rotating speed of main motor simultaneously, can make this aircraft fly forward.
After fly: while flying, suitably improve the rotating speed of main motor aloft, afterbody pressed down, can realize backward flight.
Turning flight: when front flying, the blade plane of rotation of tail undercarriage 7 is adjusted to the rotating speed that is tilted to the left and suitably improves tail undercarriage 7, can makes this aircraft bend to right; The blade plane of rotation of tail undercarriage 7 is adjusted to the rotating speed that is tilted to the right and suitably improves tail undercarriage 7, can makes this aircraft turn left.
Hovering: while aloft flying, the blade plane of rotation of tail undercarriage 7 is adjusted to level attitude, adjust the rotating speed of main motor and tail undercarriage 7, what make that anticlockwise flapping wing 5, right rotation flapping wing 6 and tail undercarriage 7 produce makes a concerted effort vertically upward and equals body weight, by fine setting, eliminates the inertia that flies after this aircraft will be in the position of hovering.
Landing: this aircraft is adjusted to behind hovering position, slowly reduces the rotating speed of main motor and tail undercarriage 7, this aircraft is by slowly vertical landing.
When main electrical fault stall, left wing's sheet 53 and right flank sheet are fixed on simultaneously to the angle of attack equates and within the scope of 4 ° ~ 15 °, this aircraft can be by the mode safe landing of gliding.
More than explanation is what do not have to make under the operating mode of interference in air flow, if there is the existence of interference in air flow, should repair partially according to the direction of air-flow and flow velocity.
The multiple-tasks such as a kind of high strength rotary flapping wing of the present invention aircraft band photographs equipment can be used for taking photo by plane, geographical measurement, traffic duty, military investigation and rescue and relief work.
