Description
Technical field
It the utility model is related to a kind of for unmanned plane and the wheel brake system of model airplane.
Background technology
At present, in fixed-wing unmanned plane and model airplane type, most of aircraft is all designed to simply
The sliding mode for running landing or catapult-assisted take-off parachute-opening landing.The advantages of running landing is slided in unmanned plane use：Time is short, carrying
Instrument and equipment are few, are advantageous to the input operation procedure that quickly takes off；But the limitation of flying field often to find repeatedly it is suitable
The place of flight landing（2.5 meters of the span, about 40 meters of the unmanned plane takeoff distance that more than 20 kilograms of take-off weight, landing are slided
It is at least reserved 100 meters to run distance）.So being so limited, unmanned plane uses catapult launcher more, and the quality of catapult-assisted take-off is herein
It is not discussed.

Deng various activities project, player is the authenticity of simulation and familiarization flight, and nearly all aircraft is all to run landing using sliding.
There was only the picture prototype of only a few at present（The imitative aircraft of height）Band wheel braking, wheel brake system can effectively shorten what is taken off and land
Ground run distance.At present, the wheel braking of model airplane aircraft of the prior art has two kinds：One kind is pneumatic braking system,
Complicated heaviness, it must be inflated and be forced into an air accumulator with automobile inflator pump before flight, after several landing brakes, air
Pressure is less than setting, brake failure；It must pressurize again.Another is electromagnetic brake system, and it is by one piece of independence
Power supply power supply, by emitter a passage remote control electric pressure regulator export one section of adjustable electric current go adhesive brake armature rub
Pad controls wheel to brake, but practical effect is unsatisfactory.First, to install one piece of independent current source additional, several kilograms are navigated
Empty model aerial vehicle, deadweight is especially undoubtedly added for small-scale workshops unmanned plane, reduce payload；Secondly, electromagnetism
Iron and magnet coil also account for larger quality, and conduction time slightly length will generate heat, and braking effect is bad.It is finally pneumatic braking system
Wheel with electromagnetic brake system is special wheel, and weight is excessive, it is impossible to common foam sponge wheel in the city that changes the outfit（Foaming
Sponge wheel has the characteristics of quality spy is light, wear-resisting, so, the general use of unmanned plane and model airplane）.
