Description
Technical field
The utility model relates to a kind of umbrella wing system that is used for wheeled parasol.
Background technology
Wheeled parasol is to appear at Hesperian a kind of novel aviation aircraft the initial stage eighties, can be used on sporting flight, aviation shooting, aerial wire laying, sows a plurality of fields such as agricultural chemicals and forestry monitoring.Promote rapidly in China in recent years.Have many advantages such as easy to learn, mobility strong, flight be comfortable flexibly, safe and reliable.Wheeled parasol grows up on the gliding parachute basis, parasol adds that a power propeller carries out the power boosting after being actually present bag, go up to the air then in ground taxi, thrust by the generation of motor blade, flight forward, and can utilize to the random change of direction of the manipulation of umbrella rope the lift-off of control motor throttle, flight and landing.The umbrella wing be wheeled parasol can fly basic, it is made of flexible fabric, keeps the wing shape of umbrella and corresponding aerodynamic force is provided by the air inlet of leading edge admission port in the flight course, and can be by it being handled the control of carrying out various flight attitudes.Whether safe and reliable can umbrella wing design-calculated quality be wheeled parasol the basis of flying and fly.
Summary of the invention
In order to satisfy the flight requirement of wheeled parasol, make it have better airworthiness and safety and reliability, the utility model provides a kind of aeroperformance, maneuvering performance and stability all reasonable umbrella wing system that is used for wheeled parasol.
The technical scheme that its technical matters that solves the utility model adopts is: comprise top airfoil, the lower aerofoil of forming the umbrella aerofoil be used to provide lift, the aerofoil that is used for opening an umbrella be shaped about two outside ribs, about rib inboard, two outsides interior rib is arranged.
Outside rib, interior rib are the PD170 air foil shape.
Described top airfoil, lower aerofoil be shaped as rectangle, aspect ratio is 3.
Top airfoil described in the utility model, lower aerofoil and about two outside ribs form the bag shaped structure of a front opening back-end closure, its inner chamber is separated by the interior rib that be arranged in parallel with two outside ribs, interior rib is more than 8.
The bag shaped structure inner chamber lateral arrangement that the outside described in the utility model rib and interior rib are formed along top airfoil and lower aerofoil, and being spaced apart between them is empty, can make air admission.
The leading edge otch a angle of the outside described in the utility model rib, interior rib is 30 degree, has good intake efficiency to guarantee umbrella wing system.
On the rib two small sircle holes are arranged in described in the utility model, to carry out loss of weight.
The utility model also comprises the umbrella rope that connects umbrella aerofoil and operation band, be used for manipulation band that the umbrella wing is controlled, umbrella rope length for exhibition long 60%.To guarantee that umbrella wing system has less resistance and maneuvering characteristics preferably.
The utility model is chosen by suitable parameters, can satisfy wheeled parasol flight characteristics, its beneficial effect is, can provide all reasonable umbrella wing of a kind of aeroperformance, maneuvering performance and stability systems technology scheme, for wheeled parasol provides the system of the umbrella wing with better airworthiness and safety and reliability.Thereby for the development of wheeled parasol with improve and to play certain impetus.
