Description

The aircraft safety resistance gauge

The utility model relates to a kind of resistance gauge, especially can make the aircraft safety resistance gauge of the fast automatic turning of aircraft, tune or urgent deceleration, stopping-down.

Along with the development of modern high and new technology, aircraft generally uses in the world.But at present aircraft exists also that angle of turn is big, tune speed curtain, also will tilt and circle and just can finish through fuselage, can't shortcoming such as promptly dodge to the place ahead obstacle or eddy current.Can only rely on the control throttle in addition or use the belly deceleration to pull deceleration.The deceleration effect not enough, and is and steady, and aircraft also can be flown off the runway sometimes, causes the accident.When external opportunity of combat is landed on aircraft carrier, use a plurality of parachutes to slow down, the deceleration effect is also bad, it is a kind of method of stupid backwardness that its practical parachute slows down, and also has shortcoming, or umbrella Zhang Bukai, can not produce resistance and not have deceleration effort, umbrella is reverse quickly all to be opened vertically with " sampled-current ", produces great resistance and impulsive force suddenly, is a significant slowdown suddenly, neither steady, dangerous again, the resistance size can't be regulated according to the deceleration needs, and umbrella and umbrella rope are not only much but also longer, also can bump and draw together, very dangerous, also to reclaim umbrella, very inconvenient.

The purpose of this utility model: be to provide that a kind of volume is little, in light weight, cost is low, simple in structure, flexible operation, " aircraft safety resistance gauge " device esy to use, safe and reliable.

The purpose of this utility model is achieved in that we are divided into four sides, upper and lower, left and right and four parts to body.Respectively the resistance gauge symmetry is installed in the middle part or the surface, four sides, rear portion of body, opens towards tail direction " forward ".Aircraft awing, as long as use a certain lateral drag device separately, just can produce drag effect immediately, just can rely on resistance, utilize inertia, aircraft self is rotated automatically to this side, when being about to 90 °, the SELF CL resistance gauge, resistance just can disappear immediately automatically, turn to also and can stop automatically immediately, realize the fast automatic turning of aircraft, have angle of turn especially little (look to resemble and turn) like " original place " " right angle ".Tune speed is fast especially, only needs aircraft self to rotate 180 ° and just finishes (estimating that the opportunity of combat tune only needs about 1 second) automatically.Can promptly dodge the place ahead obstacle or eddy current, avoid the generation of accident, make navigation safer.

Aircraft awing or when landing; use symmetrical two sides or four sides resistance gauge simultaneously; just can rely on drag effect, realize that the aircraft curtain slows down, slows down, promptly slows down and emergency braking (brake), the steady purpose of shutdown soon, aircraft also can not be flown off the runway and be caused the accident.

Technical solution of the present utility model is: be made up of parts such as body, support, pipe link, adapter shaft, safety plug, bearing seat, bearing, flexible push rod, resistance gauge, pull back spring, auto locks.

Technical solution of the present utility model: be when aloft moving according to object, air can produce drag effect to mobile, and the speed of object of which movement is fast more, and the resistance of generation is just big more, and sensitivity is just high more, and result of use is just good more.At present, aircraft also is to utilize this principle when taking off, landing or turning.But because different parts, direction, angle and using method that resistance gauge is installed on the body are different, the practical application effect that is produced is also different, and we are exactly around this principle, form in conjunction with machine design.

Safe resistance gauge requires on making: symmetrical two sides resistance gauge (as upper and lower a, left side and right) is made every effort to shape, size, consistent size, the weight of the two sides resistance gauge that special requirement are symmetrical must equate, also have the area of symmetrical two sides resistance gauge also must equate, realize steadily slowing down and steadily stopping in the time of could guaranteeing to use simultaneously symmetrical two sides or four sides resistance gauge like this.

We are divided into body, down, a left side, right four sides and four parts (also can be divided into multiaspect or more parts) (also can be installed in other position or inside to middle part or the rear portion that the resistance gauge symmetry is installed in body in the groove surfaces on four sides respectively, protruding during use), the surface of position of trapezoidal garden arc resistance gauge need be installed at original body, leave and pipe link and same shape of resistance gauge and onesize groove, the degree of depth of groove equates with the thickness of pipe link and resistance gauge, could guarantee like this pipe link and trapezoidal garden arc resistance gauge are installed in the trapezoidal garden of body arc fluting inner close fitting on body, it is the same smooth smooth with original other body surface that its surface still keeps, can not give prominence to, prevent to produce drag effect, look the same with original body, only using " forward " when opening, just resistance gauge can be seen, just drag effect can be produced.

Safe resistance gauge is front end big (towards a heading), and install rear end little (towards the tail direction) " forward ", and " following current " is open.Handle by the people, it is progressively outwards open from 0 °-90 ° of bodies to back down drive resistance gauge small end with hydraulic pressure (or machinery) push rod that will stretch, and resistance also progressively strengthens, and the resistance size can be according to turning to or the needs that slow down are regulated.We also are the resistances that utilizes " incoming flow " to produce, still " forward " open, so do not have great resistance of unexpected generation and impulsive force.Be again to rely on " incoming flow " resistance when resistance gauge does not use, towards the locking of tail " forward " SELF CL, resistance also can disappear immediately automatically, thus use, both very steady, very safe again.Aircraft also can normally use when high-speed flight, can guarantee the aircraft safety navigation, and is both suitable civilian, is more suitable for military.

Safe resistance gauge is also very special in the use, can use separately, also can use simultaneously, divide and turn to button and stop button two parts, during control button, one by promptly opening, one pine is that SELF CL (also can be the same with the use braking automobile with riding) opportunity of combat is when high-speed flight, turn to the button can only be once turning to by promptly putting, press to put again and just reverse end for end, the time of pressing is a little slightly long, opportunity of combat will be aloft up and down somersaults or about the son of turn-taking, so turn to button lighteningly to use, the time length that turns to button to press is to decide according to the needs that the speed of a ship or plane and steering angle and resistance gauge open size.The time length that stop button is pressed also is according to the speed of a ship or plane and resistance gauge stretching degree and curtain slows down, the fast deceleration, and urgent deceleration and emergency braking, the needs that steadily stop decide.

Because adopt such scheme: opportunity of combat is when taking off, as long as clear the runway, use top (back) resistance gauge, just can make the head automatic steering upwards, tail-down is realized fast automatic vertical uplift, can shorten the operating range on runway, reduce the time for lift off, improve the lift-off height, do not need climbing to raise.

Opportunity of combat awing, (not subtracting throttle) uses a certain lateral drag device separately, can realize that opportunity of combat is continuously to each different azimuth, fast automatic random, unexpected, lighteningly changing course turned or tune, or vertical uplift, decline, opportunity of combat is followed one's bent, can improve manoevreability, alerting ability and the safety of opportunity of combat greatly.Has higher and faster aggressiveness and defensive.

Opportunity of combat is used symmetrical two sides or four sides resistance gauge simultaneously when landing, can realize fast deceleration, promptly slows down and hard brake stop, can shorten the coasting distance of opportunity of combat on runway greatly, guarantees can not fly off the runway, and avoids accident.Opportunity of combat is used the four sides resistance gauge aloft simultaneously, open up into 90 ° vertical with " incoming flow ", can realize that the opportunity of combat parallel vertical lands.Use parachute ramp to stop and passenger plane to slow down more convenient, more reliable, more advanced, also safer than external opportunity of combat with the deboost device.It seems with parachute deceleration situation that according to external opportunity of combat at present, the most flourishing most advanced in the world country does not also have this device aboard, has world lead level.
