The aircraft operation principle of the present invention is as follows:
Flight control modules pass through driving first according to the current flight parameter of the aircraft that telecommand and sensor obtain Power plant 3, the second power plant 7 and third power plant 8 control the working condition of aircraft.First power plant 3 drives Swing arm 41 is swung clockwise or counterclockwise, when swing arm 41 is swung, drives connecting rod 42 to swing by the first axis pin, connecting rod 42 are rotated synchronously when swinging by 43 drive, two drive shafts 5 of cranking arm.When drive shaft 5 rotates, the support at 5 both ends of drive shaft is driven Ring 61 rotates, and supporting rod 62 and 2 unitary rotation of propeller is driven when support ring 61 rotates, before changing 2 paddle face of propeller Back rake angle.
Second power plant 7 drives supporting rod 62 to rotate, and the rotation of support ring 61 drives 2 unitary rotation of propeller, to change Become 2 paddle face of propeller or so inclination angle.
There are two types of operating modes for the aircraft of the present invention:
1, hovering pattern:It keeps realizing spot hover in propeller plan horizontal direction after changing left and right inclination angle, when hovering flies Device frontal projected area is small, lower by space limited degree for conventional aircraft.
2, offline mode:It keeps realizing rapid flight in aircraft fuselage horizontal direction after changing front and back inclination angle, due to spiral shell Revolving paddle paddle face, there are angles with fuselage, and when aircraft diving flight, angle reduces aircraft windward so that aircraft resistance is significantly Reduce, improves the mobility of aircraft.
3, yaw mode:Change the angle in propeller paddle face and fuselage, generates the thrust towards specific direction, it is more convenient Adjustment flight attitude, adapt to more complicated flight environment of vehicle.
This aircraft flexibility ratio is high, and structure design breaks conventional aircraft design concept, the comprehensive control of 3 D stereo System, greatly improves the flying quality of aircraft, and development prospect is still very extensive.According to reality, aircraft at present Achievable aerial mission range is more narrow, and tasks in areas has limitation, and the aircraft of the present invention can be instead of artificial complete It at more highly difficult and higher risk coefficient task, guarantees personal safety, there is larger application value and development prospect.
Market prospects:Streetscape shooting, adverse circumstances electric inspection process, traffic monitoring, environmental protection, really weighs problem, agriculture at monitoring cruising Industry insurance, express delivery from far-off regions, the shooting of highly difficult movie and television play, Post disaster relief, urban planning, exploitation of mineral resources, forest fire protection Monitoring, frontier defense monitoring, military surveillance and alert fire fighting monitoring, flood-control and drought relief etc..
Economic benefit:It is alternative to be manually easily accomplished time-consuming and laborious work, to improve economic benefit, reduce people Member's waste;Can complete manually can not unlabored work, for example complete the work such as search and rescue, detection of small space.
