Description
Technical field
The utility model relates to a kind of aeromodelling airplane, particularly relates to a kind of aeromodelling airplane adopting wing flap to improve lift-drag ratio, belongs to model plane technical field.
Background technology
The model of an airplane also claims model plane, is to be made up of fuselage, wing, empennage and remote operation parts, and how as scientific research, amusement, toy articles for use, the dark concern by people and hobby, become the novel commodity that a class has certain market scale.Existing aeromodelling airplane wing does not generally all have wing flap, and wing moulding is simple, but lift when taking off is smaller, and the departure time is long, and power consumption is large, and when landing the landing time long, coasting distance is far away.In addition, the most wheel of the glider below the undercarriage of aeromodelling airplane, so larger to the environmental requirement of taking off and land, especially northerly winter, once there is accumulated snow on road surface, then aeromodelling airplane takes off and is just restricted, and take-off run wheel is also not suitable for taking off on meadow.Moreover the flight time of aeromodelling airplane is by day mostly, because the light in evening is bad, can not differentiate the flight attitude of aeromodelling airplane, to such an extent as to be difficult to control aeromodelling airplane, which limits the flight time of aeromodelling airplane.
Utility model content
The utility model in order to the lift solved when existing aeromodelling airplane takes off little, the departure time is long, and power consumption is large, and when landing the landing time long, the problem that coasting distance is far away, and then a kind of aeromodelling airplane adopting wing flap raising lift-drag ratio is provided.
The utility model in order to solve the problems of the technologies described above taked technical scheme is:
Employing wing flap of the present utility model improves the aeromodelling airplane of lift-drag ratio, comprises fuselage, wing, empennage, electric propeller, nose-gear, rear undercarriage, front glider and rear glider; Wing is installed at the middle part of described fuselage, and the afterbody of fuselage installs empennage, and the head of fuselage installs electric propeller, and be provided with nose-gear and rear undercarriage before and after the bottom of fuselage, front glider is arranged on nose-gear, and rear glider is arranged on rear undercarriage; The aeromodelling airplane that described employing wing flap improves lift-drag ratio also comprises wing flap, steering wheel and connecting rod, the base angle of described wing flap is hinged on trailing edge base angle, the bottom of wing is provided with steering wheel, the pull bar of steering wheel and one end of connecting rod hinged, the other end and the wing flap of connecting rod are hinged.
Preferred: the aeromodelling airplane that described employing wing flap improves lift-drag ratio also comprises winglet, and the left and right sides wing tip of wing is provided with winglet.When aeromodelling airplane maintains normal flight, required lift produces by the pressure differential of wing upper and lower surface, due to the existence of upper and lower surface pressure reduction, near wing tip, wing lower surface air can stream upper surface, form wingtip vortex, cause the pressure reduction of wing tip near zone wing upper and lower surface to reduce, thus the lift causing this region to produce reduce.Thisly the impact of phenomenon on lift is streamed in order to weaken, aeromodelling airplane of the present utility model has installed winglet on wing tip, stream in order to hinder the air of upper and lower surface, reduce the lift induced drag because wingtip vortex causes, reduce the destruction of streaming lift, improve lift-drag ratio, reach the object increasing lift; For model plane, also can reduce power consumption, increase the flight time.
Preferred: described front glider and rear glider are sled or wheel body.Setting like this, when glider is sled, is particluarly suitable for taking off in snowfield or meadow or landing, has broken away from the restriction of flight environment of vehicle.
Preferred: the leading edge of described wing and trailing edge, and LED winglet being provided with different colours.So just can be judged the flight attitude of aeromodelling airplane by the relative position of observation lamp, thus control the flight of aeromodelling airplane, especially be applicable to the navigation at night of light difference.
Preferred: described connecting rod is by being fixed on rudder angle on wing flap and wing flap connects.Setting like this, it is more convenient to install.
Preferred: the base angle of described wing flap is hinged on trailing edge base angle by hinge.Setting like this, be convenient to connect, cost is low.
Preferred: the aerofoil profile of wing adopts round end fine stern aerofoil profile.Setting like this, improves lift coefficient, extends cruising time.
The utility model compared with prior art has following effect: the utility model improves lift when model plane take off by increase wing flap, reduce the departure time, increase landing resistance simultaneously, reduce coasting time and coasting distance, and the speed of the angular dimension control aeromodelling airplane that wing flap opens can be controlled aloft during flight, thus be conducive to carrying out tasks such as dropping and take photo by plane.In addition, reduce induced drag when aeromodelling airplane flies by increase winglet, reduce power consumption, increase the flight time.Moreover, by increasing snowfield take-off and landing device, can be implemented in and snowfield or meadow take off and lands, having broken away from the restriction of flight environment of vehicle.Finally, by mounted LED lamp, navigation at night can be realized.
