Abstract

The utility model discloses a light toy airplane with built in self-lifting air sacs, which finds a good technical measure to solve problems in the airplane design. The light toy airplane with built in self-lifting air sacs can reduce the gravity of the airplane effectively and enables the flying of the airplane needs not a too high speed of the running take-off and a too large generator power. The light toy airplane with built in self-lifting air sacs can be especially applied to the toy airplane and can enable the flying to carry out more easier. The light toy airplane with built in self-lifting air sacs can simplify the structure of the airplane and lower the cost of the airplane. The utility model comprises an airplane body, wings, an engine, a control system, a steering system and a counterweight used to regulate the centre of gravity. The utility model is characterized in that self-elevating balloons are filled in the cavity in the airplane body and the wing; light weight gas whose specific weight is smaller than the air is filled in the balloon.

Description

In fill out from rising the air bag aircraft of making light of one's life by commiting suicide

The utility model belongs to the aircraft class, plants remote-control toy aircraft or target drone or manned aircraft specifically.

Existing aircraft or autocontrol target drone have a variety of, in order to realize flight in the sky, the structure complicated design, price is more expensive, wherein main difficult technical is that the power of aero-engine must be very big, and body weight is light as far as possible, not so is difficult to produce the enough lift that overcomes body weight, and need select expensive light material for use in order to reduce body weight, strengthen cost, particularly toy airplane, that can fly is few, the price that can fly is very expensive again, and the effect of flight is undesirable.

The utility model purpose is to disclose fills out in a kind of from rising the air bag aircraft of making light of one's life by commiting suicide, for a difficult problem that solves on the above-mentioned airplane design is sought out a kind of good technical measures, can effectively reduce aircraft gravity, make aircraft flight not need too big sliding running velocity degree and too big generator power, be applied to toy airplane especially, making realize flying and more become easy, simplify aircaft configuration greatly, reduce the aircraft cost, additional other function can increase more entertainment effect.

The utility model technical conceive is, make shell components by suitable lightweight sturdy material and form the aircraft external form, space mounting is filled hydrogen or other proportion air bag light than air in fuselage and/or wing, certainly rise characteristic by this special gas, also on fuselage, settle adjustable counter balance, regulating counterweight is controlled in the airplane ascensional force line scope the overall center of gravity of fuselage, its technical scheme is: the utility model comprises fuselage, wing, driving engine, control system, maneuvering system and the counterweight of regulating center of gravity, it is characterized in that: in fuselage and the cavity place in the wing, be filled with from rising air bag, be filled with the light gas of proportion in the air bag less than air.

Fig. 1 is the utility model embodiment 1 helicopter structure figure;

Fig. 2 is the utility model embodiment 2 fixed wing aircraft constructionals drawing;

As shown in Figure 1, helicopter is by fuselage, propeller, driving engine, control system is after the counterweight of maneuvering system and adjusting center of gravity is formed bulk shape, electrical motor 2 is installed in inner empty cabin, drive propeller 6 rotations, 1 is alighting gear, the 7th, and tail slurry, the 9th, the light gas air bag, the 3rd, adjustable counter balance, the situation regulating control gross weights such as hoisting force total amount that form according to motor speed are in promoting the scope that can rise with joint efforts, and power supply can be installed on the fuselage, also can with maneuvering system together in ground staff's hand, motor is connected by lead with maneuvering system, corresponding remote control also can be installed on fuselage accept system and cooperate with the ground remote control device, is combined into remote control and forms.

As shown in Figure 2, fixed wing aircraft is made parts by suitable material and is formed external form, appropriate location installation propeller is in advance, by motor-driven, there is fixed-wing both sides, load suitable air bag adjusting counterweight at fuselage 8 and wing 5, full machine gross weight is controlled at propeller and rotates when producing pulling force, can make in the scope of taking off, in fuselage, put in the both wings, fuselage is had from lift from rising air bag 9.

The lift that the utility model produces with air bag with a kind of structure that is simple and easy to realize very much, reduce aircraft gravity, make aircraft under very little lift, can be implemented in airflight, toy airplane or target drone cost are reduced, and the engine power and the takeoff speed that require reduce, can make and taking off landing and turn to etc., simplified structure, increase its function,, increase interesting and recreational as the charged sub-acousto-optic of landing waterborne etc.

The utility model aircraft can be made the aircraft that adaptation is risen and fallen on the water, is applied to aerial gunnery target or meteorological telecontrolled aircraft widely, and practicality is more arranged on toy airplane.

Claims

1. fill out in one kind from rising the air bag aircraft of making light of one's life by commiting suicide, comprise fuselage, wing, driving engine, control system, maneuvering system and the counterweight of regulating center of gravity, it is characterized in that: in fuselage and the cavity place in the wing, be filled with from rising air bag, be filled with the light gas of proportion in the air bag less than air.
