Should invent a kind of rotary flapping wing below drives the state of flight of aircraft to be described further this invention.
Short field take-off: simultaneously start Left Hand Engine 31 and right driving engine 41, drive left flapping wing sheet 38 and right flapping wing sheet 48 is synchronized flutters in the same way, utilize control system to regulate the length of left support bar 311 and right support bar 411 to make left hook 310 and right hook 410 with high, what make that anticlockwise flapping wing device and right rotation flapping wing device produce makes a concerted effort to dead ahead or side slightly on the upper side forwards, when this makes a concerted effort enough large, when the speed that this aircraft slides is forward enough fast, adjust the aileron of port wing 3 and starboard wing 4, this rotary flapping wing drives aircraft as traditional fixed wing aircraft, to go up to the air, but take off distance will shorten greatly.
Cruise: as traditional fixed wing aircraft, the efficiency of the thruster that rotary flapping wing driving aircraft just of the present invention adopts is higher, therefore the cruise time is longer.
Vertical moving flying: simultaneously start Left Hand Engine 31 and right driving engine 41, drive left flapping wing sheet 38 and right flapping wing sheet 48 is synchronized flutters in the same way, utilize control system 4 to regulate the length of left support bar and right support bar to make left hook and right hook with high, and making a concerted effort straight up of making that anticlockwise flapping wing device 3 and right rotation flapping wing device 4 produce, when this makes a concerted effort enough large, while being greater than body weight, this rotary flapping wing drives aircraft vertically to go up to the air.
Hovering: while aloft flight, while utilizing control system 4 to regulate the length of left support bar and right support bar makes that anticlockwise flapping wing device 3 and right rotation flapping wing device 4 produce make a concerted effort straight up and equal body weight, eliminate after flight inertia this rotary flapping wing and drive aircraft will be in hovering position.
Landing: the length of adjusting left support bar and right support bar can be adjusted the direction of anticlockwise flapping wing device and right rotation flapping wing device generation thrust, as long as the direction of thrust is adjusted to front upper place, can produce component vertically upward, can shorten like this distance of landing.If the length adjustment of left support bar and right support bar is arrived to suitable position, make anticlockwise flapping wing device and right rotation flapping wing device produce making a concerted effort vertically upward of thrust and the size of making a concerted effort to be equal to or slightly greater than the weight of body, slowly be adjusted to behind hovering position, the rotating speed that slowly simultaneously reduces Left Hand Engine and right driving engine, this aircraft is by slowly vertical landing.
More than explanation is what under the operating mode that there is no interference in air flow, to make, if there is the existence of interference in air flow, should repair partially according to the direction of air-flow and flow velocity.
