Abstract

An improved wing for a slow airplane is provided, which essentially comprises an inner wing frame and is characterized in that, on the inner wing frame, a valve layer and a reticulated layer are provided; for the reticulated layer, net holes are formed by a plurality of longitudinal and cross net lines that are intercrossed; the valve layer is provided with a plurality of valves and blades. With the structure, when an airplane encounters into wind cutting while flying above a mountain, the blades in the valves of the wing body will open due to resistance, and can aid the slow falling, so as to ensure the safety of the persons and airplane, hence the utility model is economically practical.

Description

The improved wing of aircraft at a slow speed that is applicable to

Technical field

The utility model relates to a kind of aircraft, and particularly a kind of tool is guaranteed the improved wing of aircraft at a slow speed that is applicable to of man-machine safety.

Background technology

Along with the pay attention to day by day of people to recreation, various stress-relieving activities also just arise, and wherein are engaged in the outdoor activities that aircraft at a slow speed circles in the air, especially the courage and insight challenger go after like a flock of ducks, one of indispensable project.

And take a broad view of various aircrafts at a slow speed at present, as hang gliding, light plane etc., as shown in Figures 1 to 4, its wing-body 10 all is to make with glass fibre or canvas external coating body 101, and be airtight design (as shown in Figure 1), though can enjoy the high with fair wind enjoyment (as shown in Figure 2) that crow is looked down from a height of looking forward or upwards when when weather is good, flying, when the area that runs into that lofty mountains and steep hills, the situation that often causes the basipetal wind of aerial air-flow to cut directly to pass through press wing body 10 is (as Fig. 3, shown in 4), so that wing-body 10 is subjected to overhead sinuous flow resistance, and formation unstable flight state, and be forced to rapid drawdown rapidly, the lucky man can turn danger into safety and arrive safely ground, and unfortunate person often causes injury to personnel because of aircraft crash out of control, even jeopardize life, so how to improve the design of aircraft wing,, exigence arranged in fact with the guarantee that provides another layer of aircraft handling person to concern life safety.

In view of this, this creator is in line with actively probing into, smart diligent cultivation ask spirit, cooperate and be engaged in the expertise that relevant industries accumulate for many years and design and develop practical experience, study intensively with great concentration and study, and have the utility model to produce eventually through actual.

Summary of the invention

The utility model is that a kind of improved wing of aircraft at a slow speed that is applicable to will be provided, and makes it have to produce and auxiliaryly slowly fall function with solution, and guarantees man-machine safe technical matters.

It is such solving the problems of the technologies described above the technical scheme that is adopted:

A kind of improved aircraft wing at a slow speed that is applicable to mainly includes an inner wing frame, it is characterized in that: a valve layer and a lamina reticularis are set on this inner wing frame;

This lamina reticularis is vertically to reach horizontal netting twine and staggered formation mesh for many;

Default a plurality of valve and the blade of being arranged with of this valve layer;

This blade is that cloth or the film after being handled by elasticity is made.

The utility model mainly is to be provided with a valve layer and a lamina reticularis in wing-body, when aircraft when high mountain flight is cut as wind, blade is the unlatching shape because of being subjected to resistance in the valve of wing-body, has the auxiliary slow function of falling, make it have to produce and auxiliaryly slowly fall function thereby solved, and guarantee man-machine safe technical matters.

The utility model is simple in structure, is a kind of wing of aircraft at a slow speed that is applicable to, when aircraft when high mountain flight is cut as wind, blade is the unlatching shape because of being subjected to resistance in the valve of wing-body, have to produce and auxiliaryly slowly fall function, and then reach and guarantee man-machine safety, and the tool practicality.

The specific embodiment

At first, see also shown in Figure 5ly, the utility model is the improved wing of aircraft at a slow speed that is applicable to, this wing-body 1 mainly is made up of an inner wing frame 11, a valve layer 12 and a lamina reticularis 13;

This inner wing frame 11 is for general known support body, so repeat no more;

This valve layer 12 is preset and is arranged with a plurality of valve 121 (as shown in Figure 7) and blade 122, and this blade 122 is to be formed by cloth or film after the elasticity processing;

This lamina reticularis 13 is to have many vertically to reach horizontal netting twine 131 and staggered formation mesh 132;

During combination, see also shown in Figure 7, at first lamina reticularis 13 and valve layer 12 covered and be connected with and be coated on inner wing frame 11 heads, make the upper and lower layer of head all be provided with lamina reticularis 13 and valve layer 12, valve 121 and blade 122 then are located at place, inner wing frame 11 upper and lower end bottom sides.

Use when implementing, see also shown in Figure 6, when aircraft at a slow speed when rising, because wing-body 1 upside lamina reticularis 13 is subjected to air-flow resistance, make air-flow pass mesh 132 and valve 121 forces blade 122 to be opened, to allow air-flow reduce resistance by mesh 132 and valve 121 rapidly; Otherwise when aircraft descended rapidly, at this moment, wing-body 1 bottom side valve layer 12 was because of being subjected to air-flow resistance, and forced blade 122 to be posted by valve 121 places and present closed condition and increase wing-body 1 buoyancy, the danger when slowing down rapid drawdown; In the high mountain area that links to each other, cut as the basipetal wind of air-flow again, at this moment, blade 122 presses down and is the unlatching shape because of being subjected to wind-force, influences the fugitiveness of aircraft flight to slow down sinuous flow, and the energy safe falling.In addition, the utility model is also done aileron applicable to helicopter and is flown, and when main wing (screw propeller) fault, aileron (wing-body) 1 valve 121 blades 122 are promptly suitably opened, and can produce to assist to delay and fall function, and then reach the effect of guaranteeing man-machine safety.

The above only is a preferred embodiment of the present utility model, when can not limiting the scope that the utility model is implemented with it, promptly allly applies for a patent the equalization of being done according to the utility model and changes and modify, and all should still belong in the scope that the utility model patent contains.

In sum, the utility model not only really belongs to innovation on spatial shape, and can promote multinomial effect, should fully meet each important document requirement of utility model patent, so propose utility application in accordance with the law.
