Background technology
Powerful along with country, first aircraft carrier " Liaoning " number is on active service, and China's sea power obtains landmark development.Next will have second successively, the 3rd aircraft carrier is on active service.Aircraft carrier will form powerful fighting capacity, just must carry carrier-borne aircraft.It is crucial for training a collection of high-quality carrier-borne pilot.Usual common fighter-pilot will could perform combat mission by the flight training of 500 ~ 600 hours, and carrier-borne aircraft pilot not only will complete these substances, also needs all difficulties overcoming aircraft carrier landing, and the training time is longer, and risk is larger.
Aircraft-carrier flight deck is due to bad environments, and narrow space, training becomes dangerous, and accident rate is high, so carrier-borne aircraft pilot must train with the special environment adapting to aircraft carrier for a long time.The key of aircraft carrier flight landing is takeoff speed, sinking speed and flight downslide angle.General flight simulator is the six degree of freedom fly simulation training in static state, the impression of carrier-borne aircraft key element of landing on aircraft carrier can not be reflected really, carrier-borne aircraft pilot has to pass through a large amount of real flight training, constantly increases flying experience, could ensure the success ratio of landing.
Summary of the invention
The object of the present invention is to provide ship-board aircraft pilot dynamic simulated training system, the landing flight of real simulation ship-board aircraft on aircraft carrier, make ship-board aircraft pilot experience the impression of carrier-borne aircraft landing on aircraft carrier, solve the problem that ship-board aircraft pilot training cost is high, the flight psychology of pilot is lacked experience.
Ship-board aircraft pilot dynamic simulated training system of the present invention, comprise simulator, its simulator arranges wheel and rotating mechanism, and the wheel of simulator contacts with slide rail; Slide rail arranges low level horizontal segment and high-order horizontal segment, is slope section between low level horizontal segment and high-order horizontal segment; All arrange hoisting mechanism under the low level horizontal segment of slide rail He under high-order horizontal segment, the dragrope in hoisting mechanism twists on windlass; Simulator is connected dragrope by draft arm with draw hook; The control device controlling hoisting mechanism, rotating mechanism and draft arm is set in simulator, in simulator, also clamping device is set.
Move better to make simulator, keep stable in moving process, the present invention also arranges simulator mobile platform further, is settled on a mobile platform by simulator, the rotating mechanism of simulator is arranged between simulator and mobile platform, and wheel and draft arm are all arranged under mobile platform; Under mobile platform, also arrange power supply wheel, power supply wheel contacts with the power cable on slide rail; In simulator, electric device and electric control gear are also set.Here, the power cable on slide rail provides electric energy by power supply wheel to simulator, and electric device can make simulator electricity start and electric drive.
In the present invention, draw hook is connected for linking up with draft arm.Draft arm is made to be convenient to hang up with dragrope or throw off.
In system of the present invention, rail selected by slide rail, and slide rail radical is two or four, and wheel is rubber guide wheel.
Slide rail shape is preferably I shape, and upper and lower two wheels contact the both sides up and down of the upper traverse rod of I shape slide rail respectively.Such structure is equivalent to be snapped in by the upper traverse rod of track between upper and lower two wheels, meanwhile, because there is slide rail both sides, just achieve to simulator up and down four direction location restriction, simulator steadily is moved along slide rail.
In order to simulate the landing flight of ship-board aircraft on aircraft carrier more truly, in system of the present invention, the angle of slope and level is 8 ~ 15 degree, and low level horizontal section length is 100 ~ 120m, and high-order horizontal section length is 100 ~ 120m, and slope section length is 40 ~ 60m.
In order to apply larger damping force when shutting down, the present invention also arranges obstruction device at the low level horizontal segment of slide rail and the end of high-order horizontal segment.During shutdown, draft arm touches this obstruction device, and obstruction device will play Intercepting effects.
In order to apply larger boosting power at block clearance time, obstruction device is preferably adopted spring by the present invention.During shutdown, spring is compressed, and plays Intercepting effects.And when block clearance time is given and draft arm thrust by the spring that compresses, play booster action.
In the present invention, the side of the motor of hoisting mechanism connects flywheel by clutch coupling, and the opposite side of motor connects windlass by another clutch coupling, and flywheel and windlass are connected to brake drum.
Preferably, flywheel diameter is 6 ~ 10 times of shaft diameter.
As the critical component in system, the Main Function of hoisting mechanism makes simulator in a short period of time (100 ~ 120m) in (less than 2 seconds more than 1 second), very short distance, can reach very high speed at block clearance time.The ship-board aircraft start of a race that is virtually reality like reality is taken off, and will, in short 100m, make the speed of simulator reach about 200km/h.Equally, another Main Function of hoisting mechanism makes simulator in a short period of time, in very short distance, reduce to zero from very high speed (about 200km/h).
For this reason, hoisting mechanism of the present invention takes the structure of double clutch, double-brake drum, and takes flywheel and to operate in advance the auxiliary mode accelerated.Simulator needs block clearance time, is first unclamped by the clutch coupling of the windlass side in hoisting mechanism, is closed by the clutch coupling of opposite side; Actuating motor, flywheel will rotate, until reach maximum (top) speed; Then the clutch coupling of flywheel side is unclamped, rear flywheel rotate with very high velocity inertia; Meanwhile closed by the clutch coupling of windlass side, motor drives windlass to rotate, and then drives dragrope to move, and resulting belt dynamic simulated device moves; When simulator motion reaches certain speed (due to the restriction of time, this speed does not reach maximum (top) speed certainly, also certainly low than the rotating speed of flywheel now), again the clutch coupling of flywheel side is closed, the flywheel of inertial rotation just applies boosting power to windlass, further raising windlass rotating speed, makes the movement velocity of simulator greatly accelerate, reaches the speed of regulation in official hour.Now draft arm must be thrown off with dragrope.No matter be in low-level section standby for takeoff, or prepare landing in high-level section, above-mentioned shape is all the same.Only hoisting mechanism is not same set of.Here, because the diameter of flywheel is very large, therefore the inertia of flywheel is also just very large, when flywheel is after motor driving is issued to maximal rate, even if clutch coupling unclamps, motor no longer gives flywheel power, within very short time, flywheel relies on inertia, and its rotating speed would not have too many reduction, still can keep very large.
When simulator needs to shut down, draft arm must hang up again with the dragrope of another set of hoisting mechanism.This set of hoisting mechanism two clutch couplinges are all closed, brake two brake drums simultaneously, by double-brake drum to windlass effect, make dragrope as far as possible motionless, and then give restraining function to simulator, and give effective deceleration to simulator, make it in official hour (less than 2 seconds more than 1 second) and stop.
System of the present invention, has three devices to provide driving force: hoisting mechanism, electric device and obstruction device, so in a short period of time the speed of simulator can be brought up to required degree.Similarly, also three devices are had to provide damping force: the clamping device (clamping device in simulator is for braking the wheel of simulator) in hoisting mechanism, obstruction device and simulator, so in a short period of time the speed of simulator can be reduced to zero from very high.
System of the present invention, is skillfully constructed, and can carry out circulating analog training continuously.The rotating mechanism of simulator is convenient to be turned around by simulator easily after a shutdown, like this, takes off and can start again training landing after stopping trained.Similarly also can take off trained to land and training can be started again after stopping.Obstruction device can also as roll booster in addition.Two cover hoisting mechanisms are exquisite especially, not only can accelerate, can also slow down.And after the start of a race, the draw hook of this set of hoisting mechanism will stop at front end, until simulator turn to later carry out landing shut down time, hook will tangle draft arm in this position, for slow down leave enough distances.
Ship-board aircraft pilot dynamic simulated training system of the present invention, simulate the landing flight of ship-board aircraft on aircraft carrier truly, ship-board aircraft pilot is made to experience the impression of carrier-borne aircraft landing on aircraft carrier, the problem that the flight psychology solving pilot is lacked experience, overcome ship-board aircraft pilot and truly train the defect that danger is large, cost is high, greatly can improve training effect.

See Fig. 1, Fig. 2 and Fig. 3.
Ship-board aircraft pilot dynamic simulated training system of the present invention, comprise simulator 2, simulator 2 arranges rubber wheels 13 and rotating mechanism 11, and the rubber wheels 13 of simulator 2 contacts with slide rail 4; Slide rail 4 arranges low level horizontal segment (left side section of Fig. 1) and high-order horizontal segment (the right section of Fig. 1), is slope section (interlude of Fig. 1) between low level horizontal segment and high-order horizontal segment; Under the low level horizontal segment of slide rail 4 He under high-order horizontal segment, hoisting mechanism (low level hoisting mechanism 6 is all set, with high-order hoisting mechanism 9), the dragrope (low level dragrope 7 and higher traction rope 8) in hoisting mechanism twists on windlass (windlass 25 see Fig. 4); Simulator 2 is connected dragrope (low level dragrope 7 and higher traction rope 8) by draft arm 14 with draw hook (higher traction hook 3 and low level draw hook 15); The control device (in simulator 2, not shown in FIG.) controlling hoisting mechanism, rotating mechanism 11 and draft arm 14 is set in simulator 2, clamping device (in simulator 2, not shown in FIG.) is also set in simulator 2.
Simulator 2 is settled on a mobile platform 10, and the rotating mechanism 11 of simulator 2 is arranged between simulator 2 and mobile platform 10, and rubber wheels 13 and draft arm 14 are all arranged under mobile platform 10; Under mobile platform 10, also arrange power supply wheel 12, power supply wheel 12 contacts with the power cable (not shown in FIG.) on slide rail 4; Electric device and electric control gear (all in simulator 2, not shown in FIG.) are also set in simulator 2.
Draw hook (higher traction hook 3 and low level draw hook 15) is connected for linking up with draft arm 14.
Slide rail 4 is rail, and the radical of slide rail 4 is two.
Slide rail 4 shape is I shape, and upper and lower two rubber wheels 13 contact the both sides up and down of the upper traverse rod of I shape slide rail 4 respectively.
The slope of slide rail 4 and the angle of level are 8 ~ 15 degree, and low level horizontal section length is 100 ~ 120m, and high-order horizontal section length is 100 ~ 120m, and slope section length is 40 ~ 60m.
Arrange low level obstruction device 5 in the end of the low level horizontal segment of slide rail 4, the end of high-order horizontal segment arranges high-order obstruction device 1.
High-order obstruction device 1 and low level obstruction device 5 are spring.
See Fig. 4.
The left clutch 22 that passes on left of the motor 21 of hoisting mechanism connects flywheel 23, and the right side of motor 21 connects windlass 25 by right clutch 24, and flywheel 23 and windlass 25 are connected to brake drum (left brake drum 26 and right brake drum 27).
The diameter of flywheel 23 is 6 ~ 10 times of main shaft 28 diameter.
To take off training:
Simulator 2 is positioned at the end of the low level horizontal segment of slide rail 4, now simulator 2 be connected under low level horizontal segment hoisting mechanism by draft arm 14 and low level draw hook 15 on low level dragrope 7.Low level obstruction device 5 is in the state being pulled arm 14 and compressing.Simulator 2 is in on-position.
Trainer prepares in simulator 2.To be energized work then to low level hoisting mechanism 6, the electric device in simulator 2 and electric control gear start.See Fig. 4.Motor 21 operates, and unclamp left brake drum 26 and right brake drum 27, unclamped by right clutch 24, left clutch 22 closes, and now, motor 21 flywheel driven 23 operates.
When flywheel 23 runs to maximal rate, unclamp left clutch 22, close right clutch 24 simultaneously, unclamps the braking in simulator 2.Windlass 25 in low level hoisting mechanism 6 rotates, and drives low level dragrope 7 to move.Low level dragrope 7 draws simulator 2 by low level draw hook 15 and the draft arm 14 that is hooked together and moves right.Power to the electric device in simulator 2 by the power cable on slide rail 4 and power supply wheel 12, electric device also drives simulator 2 to move right simultaneously.Meanwhile, due to draft arm 14 along with simulator moves right, lifted restrictions by the low level obstruction device 5 compressed, the elastic force of spring also gives 2 one, simulator ejection force to the right.Under the acting in conjunction of tractive force, motor driving force and ejection force, simulator 2 can reach very high speed within very short time.But owing to wanting the takeoff condition of real simulation ship-board aircraft, thus must limit very strict condition, in the time being namely no more than 2 seconds in 100m, make the speed of simulator 2 reach about 200km/h.The effect of above-mentioned three power does not still accomplish this point, because the time is too short, the rotating speed of windlass 25 and motor 21 can not reach maximum speed within the so short time.And flywheel 23 due to diameter very large, so inertia is very large, after being accelerated to maximal rate in advance, still can keep great speed in the extremely short time, the speed that this speed can reach within the extremely short time than motor 21 is large.So now need left clutch 22 again to close, the flywheel 23 run up is allowed to give windlass 25 1 accelerating forces.The translational speed of simulator 2 brings up to setting the most at last.
Afterwards, simulator 2, after low level horizontal segment high speed slide 100m, will be climbed up the slope section that angle is 8 degree, enter takeoff condition.Now trainer needs the connection of disengagement draft arm 14 and low level draw hook 15 and by control device, low level draw hook 15 is rested on to locate near taking off.Give the electric device power-off in simulator 2 simultaneously.Simulator 2 enters inertia and takes off.
When simulator 2 is after slope section high speed slide 40m, enter high-order horizontal segment.Training of now taking off completes, and starts training of stopping.The higher traction hook 3(higher traction hook 3 that draft arm 14 under simulator 2 mounts on higher traction rope 8 stops in place in advance), by the left brake drum 26 in high-order hoisting mechanism 9 and right brake drum 27, give a damping force to simulator 2.Clamping device simultaneously in working train family device 2, brakes rubber wheels 13.When simulator 2 in deceleration to the end of high-order horizontal segment, draft arm 14 touches high-order obstruction device 1, and high-order obstruction device 1 applies resistance to simulator 2 while being compressed.Under the triple role of high-order hoisting mechanism 9, high-order obstruction device 1 and simulator 2 wheel braking, simulator 2 is just reduced to zero from the high speed of 200km/h and is stopped in short 100m.Thus complete training of stopping.
Finally by manipulation, rely on rotating mechanism 11, simulator 2 revolves turnback, can carry out decline training downwards.
Decline training:
Carrying out taking off with simulator 2 trains just the same, and under simulator 2 is subject to the acting in conjunction of the motor driving force in the tractive force of high-order hoisting mechanism 9, the ejection force of high-order obstruction device 1 and simulator 2, simulator 2 can reach very high speed within very short time.The inertial force of the flywheel 23 in addition in high-order hoisting mechanism 9 accelerates, and the translational speed of simulator 2 brings up to setting the most at last.
Afterwards, simulator 2, in high-order horizontal segment end, is thrown off the connection of draft arm 14 and higher traction hook 3 and by control device, higher traction hook 3 is rested near decline place.Give the electric device power-off in simulator 2 simultaneously.The slope section that simulator 2 along angle will be 8 degree, enters decline state.
Afterwards, simulator 2 enters the parking of low level horizontal segment.Draft arm 14 hooks the low level draw hook 15 just having rested on correct position (near taking off place) when taking off, under the triple role of low level hoisting mechanism 6, low level obstruction device 5 and simulator 2 wheel braking, simulator 2 is just reduced to zero from the high speed of 200km/h and is stopped in short 100m.
Finally by manipulation, rely on rotating mechanism 11, simulator 2 revolves turnback, can carry out training of taking off again again.
