Abstract
A kind of telescopic wing, by wing I (7), wing II (8), wing III (9), pulley I (2), pulley II(11), cable wire I (3), cable wire II (10), hydraulic pressure pole socket (4), hydraulic stem (5), hydraulic actuating cylinder (6) form.The effect of wing produces lift, to support that aircraft flies aloft.Identical wing produce the speed of lift and aircraft and height relationships tight.Identical wing, time highly identical, air speed is faster, and lift is larger; When speed is identical, highly higher, lift is less.This telescopic wing, on the high-altitude of rarefaction of air during cruising flight, wing stretches out completely, and the span of ultra-wide makes aircraft only need consume lower fuel, maintains the object that the lower speed of a ship or plane can reach the prolongation hang time; In departure or when making a return voyage, wing shortens completely, thus improve flying speed, the time shortening departure or make a return voyage.
Description
Technical field
The present invention and a kind of wing, particularly relate to a kind of telescopic wing.
Background technology
Along with science and technology, military needs, the flying height of high altitude reconnaissance plane is more and more higher, and the cruising altitude as China " Xiang dragon " has reached 18000 meters, and the cruising altitude of " global hawk " of the U.S. has reached 19800 meters, exceed 16000 meters, convective zone, reach stratospheric height.Due to highly higher, air is thinner, the aircraft flown in the high-altitude of rarefaction of air, in order to keep enough lift, or improves flying speed, or widens the span of aircraft.Must increasing fuel consumption owing to improving flying speed, shorten the time that aircraft is detained aloft.Therefore, in order to reach the object extending the residence time aloft, the span of high altitude reconnaissance plane all very wide.As " the Xiang dragon " of China, the span 25 meters, " global hawk " span of the U.S. reaches 35.4 meters.But the span of aircraft is too wide, the flying speed of aircraft when sailing or make a return voyage can be reduced again, simultaneously the consumption of increasing fuel.
Summary of the invention
The object of the invention is can not solve above-mentioned contradictory problems for existing background technology, propose a kind of telescopic wing.This telescopic wing, time cruising in the high-altitude of rarefaction of air, wing stretches out completely, and the span of ultra-wide makes aircraft only need consume lower fuel, maintains the object that the lower speed of a ship or plane can reach the prolongation hang time; In departure or when making a return voyage, wing shortens completely, thus improve flying speed, the time shortening departure or make a return voyage.
A kind of telescopic wing, is made up of wing I7, wing II8, wing III9, pulley I2, pulley II11, cable wire I3, cable wire II10, hydraulic pressure pole socket 4, hydraulic stem 5, hydraulic actuating cylinder 6.It is characterized in that: wing I7 installs on the fuselage 1, wing II8 sliding sleeve is arranged in wing I7, wing III9 sliding sleeve is arranged in wing II8, hydraulic pressure pole socket 4 is fixing on the fuselage 1, hydraulic stem 5 one end is hinged on hydraulic pressure pole socket 4, the other end coordinates with hydraulic actuating cylinder 6 to be installed, hydraulic actuating cylinder 6 one end is fixed on wing II8, the other end is provided with pulley II11, pulley I2 is fixed on wing II8, cable wire I3 one end is fixed on wing I7, the other end is fixed on wing III9 by what tighten after pulley I2, cable wire II10 one end is fixing on the fuselage 1, the other end is by being fixed on wing III9 of tightening after pulley II11.
The present invention is achieved in that
When stretching wing work: ejected by hydraulic stem 5 after hydraulic actuating cylinder 6 pressurized, hydraulic actuating cylinder 6 drives wing II8, pulley II11, pulley II11 by cable wire II10 drive wing III9, thus makes wing II8 stretch out wing I7, drives wing III9 to stretch out wing II8; When shrinking wing work: shunk by hydraulic stem 5 after hydraulic actuating cylinder 6 pressure release, hydraulic actuating cylinder 6 drives wing II8 retraction wing I7, cable wire II10 drives wing III9 retraction to make wing II8 by pulley I2.
Advantage of the present invention:
This telescopic wing, on the high-altitude of rarefaction of air during cruising flight, wing stretches out completely, and the span of ultra-wide makes aircraft only need consume lower fuel, maintains the object that the lower speed of a ship or plane can reach the prolongation hang time; In departure or when making a return voyage, wing shortens completely, thus improve flying speed, the time shortening departure or make a return voyage.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
1 be fuselage, 2 be pulley I in figure, 3 be cable wire I, 4 be hydraulic stem, 5 be hydraulic stem, 6 be hydraulic actuating cylinder, 7 wing I, 8 are wing II, 9 be wing III, 10 be cable wire II (10), 11 for pulley II.
Detailed description of the invention
A kind of telescopic wing, is made up of wing I7, wing II8, wing III9, pulley I2, pulley II11, cable wire I3, cable wire II10, hydraulic pressure pole socket 4, hydraulic stem 5, hydraulic actuating cylinder 6.It is characterized in that: wing I7 installs on the fuselage 1, wing II8 sliding sleeve is arranged in wing I7, wing III9 sliding sleeve is arranged in wing II8, hydraulic pressure pole socket 4 is fixing on the fuselage 1, hydraulic stem 5 one end is hinged on hydraulic pressure pole socket 4, the other end coordinates with hydraulic actuating cylinder 6 to be installed, hydraulic actuating cylinder 6 one end is fixed on wing II8, the other end is provided with pulley II11, pulley I2 is fixed on wing II8, cable wire I3 one end is fixed on wing I7, the other end is fixed on wing III9 by what tighten after pulley I2, cable wire II10 one end is fixing on the fuselage 1, the other end is by being fixed on wing III9 of tightening after pulley II11.
When stretching wing work: by hydraulic stem 5 after hydraulic actuating cylinder 6 pressurized) eject, hydraulic actuating cylinder 6 drives wing II8, pulley II11, and pulley II11 by cable wire II10 drive wing III9, thus makes wing II8 stretch out wing I7, drives wing III9 to stretch out wing II8; When shrinking wing work: shunk by hydraulic stem 5 after hydraulic actuating cylinder 6 pressure release, hydraulic actuating cylinder 6 drives wing II8 retraction wing I7, cable wire II10 drives wing III9 retraction to make wing II8 by pulley I2.
