Description

Air force pilot's bailout digital safety landing control device

Technical field

The utility model relates to a kind of air force pilot's bailout digital safety landing control device, is applicable to the landing of aircrew's emergency escape automatic safe.

Background technology:

At present, after the parachute jumping of air force pilot's emergency escape, its landing modes still adopts not have controls freely descend slowly and lightly mode or the simple landing modes under the pilot guidance.When the landing zone be in topography and geomorphology complicated with cloud, mist, night meteorology; Or be in the hazardous location that can not land in traffic route, power communication line facility, town building, oil depot power station etc.; Or the pilot is when being in injured state, and present pilot to escape landing modes can not adapt to new war fighting requirement.In the air battle, the latter end safety after the pilot to escape parachute jumping realizes that the automatic control of digitizing has become necessary and possibility.

The utility model content:

For solving the deficiency of prior art, the utility model provides a kind of air force pilot's bailout digital safety landing control device, realizes the landing of the aircrew of air force emergency escape automatic safe.

The technical scheme that the utility model adopted is: control device comprises the regional geographical information query of landing, selects landing place, evades the interior explosive area, landing zone and the information processing in selected level point; And servo component is amplified, handled to the signals collecting of the height in parachute and selected level point, azran deviation, computer control assembly, signal; The regulating and controlling digital signal is sent in the calculating of, gun parallax poor to descent altitude and range difference, and signal is through amplifying, drive stepping motor, and stepper motor is controlled rotational angle according to pulse signal, realizes landing-gear control rope is carried out the pulling control of different orientations; After landing-gear landed, emission of open site signal and wigwag showed (night).

The computer control assembly comprises geography information, the regional risk averse of landing and selected level point system, surveys high parts, navigation means and control assembly; When the pilot parachutes escape; The control device self-opening power supply; When sinking speed＜1 meter/100ms, confirm that parachute is opened, promptly triggering system is connected whole power supplys of control device automatically; Start GIS-Geographic Information System, the regional risk averse of landing and selected level point system, signals collecting and computer s operation control, signal amplification, servocontrol mechanism, send the angle of cut, range difference and three groups of digital controlled signals of difference in height respectively.

Servo control mechanism comprises stepper motor, electromagnetic clutch etc., is connected the different azimuth electromagnetic clutch through the input pulse signal that amplifies respectively with the control signal that computer sends, and in conjunction with the rotating of stepper motor, realizes two control of separate unit driven by motor rop exercise work.

Instantly after reduction of speed degree=0/s confirmed to land, location signal transmitter and night lights display unit started automatically, send pilot position wireless signal and night lights shows signal.

The process that is implement device control is: pilot's parachute jumping → measuring height; Confirm parachute-opening → start-up control device → inquiry landing zone; Evade the landing risk area; The angle of cut between selected level point → calculating parachute orientation and the setting level point and range difference → send digital signal → signal amplification → drive stepping motor, dynamically handling parachute heading angle adjustment → pilot lands → emission of open position signal and light display unit, close servocontrol mechanism.

The beneficial effect of the utility model is: through the inquiry to the zone of landing; Evade the dropping zone risk; The negative feedback Automatic Control Theory with the cycle calculations of control datas such as the level point difference in height of setting, gun parallax, range difference, is used in selected level point; Whole operations adjustment controls after the completion parachute-opening; And after landing, send functions such as position signalling and light shows signal automatically, and reach the safe falling escape purpose of pilot under complicated meteorology and geographical environment after the parachute jumping, change the problems such as various harm that present pilot to escape parachuting mode possibly brought.Can realize that high-altitude and hedgehopping person's parachuting controls automatically; Can reach the accurate landing of landing radius＜100 meter; Can accurately land the pilot under abominable weather environment and the complex-terrain geomorphologic conditions, guarantee pilot to escape latter end process safety.
