Description

Fly cover in the dark cabin of cloth-curtain type plane

Technical field: the utility model relates to a kind of Fly cover in the dark cabin of cloth-curtain type plane that aircraft flight instrument when training use that is used for.

Background technology: hidden-cockpit flight-hood is the isolated plant of aircraft instrument flight training.The main effect of this device is to reach blindly effect, also must guarantee flight safety and safe life-saving simultaneously.At present, hidden-cockpit flight-hood can be divided three classes both at home and abroad: a. is installed in the flight cover on aircraft windscreen and the portable cover; B. be placed in pilot's head curtain cover on every side; C. be fixed on aviator's helmet or the flight of the brim of a hat formula on crash helmet cover that the pilot wears.In this flight cover of three types, only the c class is suitable for through canopy ejection lifesaving type, but ejection acceleration is produced when launching nose-down pitching moment, rolling moment can cause certain mechanical damage to the pilot, influence safe life-saving.

Summary of the invention: the purpose of this utility model provides a kind of Fly cover in the dark cabin of cloth-curtain type plane that the pilot is had no mechanical damage that is applicable to through canopy ejection lifesaving type.Technical solution of the present invention is, the guide rail skeleton is corresponding with the arc of passenger cabin front windshield skeleton, opens and closes the mould assembly notch on it, and an end of web member snaps in the notch of skeleton; The lower end of web member articulates the door curtain made of cloth, and lock and Connection Block are welded on the two ends of guide rail skeleton respectively and fix with aircraft cockpit front windshield arc frame; Latch inserts in the through hole of lock, and pocketed springs on the latch, limited bolt insert in the pilot hole of lock and stopper slot and lock by latch connect as one, and brace one end is articulated on the latch by the notch of lock one end, and the other end links to each other with elastic band; Latch inserts in the through hole of Connection Block, pocketed springs on the latch, limited bolt inserts in the pilot hole of Connection Block and stopper slot and Connection Block by latch connect as one, and stator one end is socketed on the latch by the notch of Connection Block one end, and the other end links to each other with elastic band.Web member is made up of connecting link and spheroid, and an end of connecting link is a bulb, and the center of spheroid has stepped hole.

The utility model can be blocked the extravehicular environment sight line of aircraft front windshield transparent region effectively; Do not influence the visual field, pilot dead ahead taking off, folding when landing; Be convenient to quick loading and unloading; When emergency ejection is disembarked, be equipped with mutually, and do not need any additional move with through canopy ejection; Simultaneously yet can not produce extra ejection acceleration and cause damage the pilot.The present invention is simple in structure, flexible operation, safeguard convenient disassembly, do not influence ejection channel, be very suitable for being installed on the windscreen arc frame of through canopy ejection lifesaving type, also be applicable on the windscreen arc frame that is installed in canopy jettison ejection lifesaving type simultaneously, realize the purpose of blind-flying training.

Embodiment:

Guide rail skeleton 1 is corresponding with the arc of passenger cabin front windshield skeleton, opens and closes mould assembly notch 28 on it, and an end of web member 9 snaps in the closo notch 28 of skeleton; The lower end of web member 9 articulates the door curtain made of cloth 5 and 27, and lock 3 and Connection Block 8 are installed in the two ends of guide rail skeleton 1 respectively and fix with aircraft cockpit front windshield arc frame; Latch 10 inserts in the through hole of lock 3, pocketed springs 11 on the latch 10, limited bolt 12 inserts in the pilot hole 16 of locks 3 and the stopper slot 15 by latch 10 connects as one with lock 3, brace 4 one ends are articulated on the latch 10 by the notch 14 of lock 3 one ends, and the other end links to each other with elastic band 6; Latch 17 inserts in the through hole of Connection Block 8, pocketed springs 22 on the latch 17, limited bolt 20 inserts in the pilot hole 23 of Connection Blocks 8 and the stopper slot 21 by latch 17 connects as one with Connection Block 8, stator 7 one ends are socketed on the latch 17 by the notch 18 of Connection Block 8 one ends, and the other end links to each other with elastic band 6.

Web member 9 is made up of connecting link 24 and spheroid 25, and an end of connecting link 24 is a bulb 26, and the center of spheroid 25 has stepped hole.

Adopting the arc pipe fitting of many R combinations according to the feature of aircraft windscreen is guide rail skeleton 1, makes closo notch 28 thereon, and this closo notch is the motion guide rail of the door curtain made of cloth 5,27 when launching and folding.Three auricles 2 of configuration are used for and being connected of aircraft windscreen structure on the guide rail skeleton 1, and the spheroid 25 on the web member 9 enters closo notch 28 by the interior mother rib lateral rotundum of guide rail skeleton 1 one ends, and the door curtain made of cloth 5 and 27 is hung on the guide rail skeleton 1.When carrying out non-instrument flight subject, the guide rail skeleton can stay on aircraft, and 9 of web members can unload preservation expediently from the circular hole of skeleton.

Lock 3, Connection Block 8 are welded on the left and right lower end of guide rail skeleton 1 respectively, limited bolt 12 fuses latch 10, spring 11 with lock 3, one end of latch 10 is shaped on the kidney slot hole, path for limited bolt 12, web member 9 and the door curtain made of cloth 5 and 27 location and locking can be able to be finished the expansion of the door curtain made of cloth 5,27 and the operating function that folds simultaneously.Latch 10 all is quick-release types with the combination and the releasing of the door curtain made of cloth.

The door curtain made of cloth 5,27 adopts double-deck dark textile to make, and profile is similar fan-shaped, and when the door curtain made of cloth 5,27 full expand states, the sight line of blocking windshield glass promptly realizes the effect of blind flight; The door curtain made of cloth 5,27 folds the rear windshield transparent region visual field and recovers, and satisfies the visual field requirement of taking off, landing.Web member 9 is a ball connecting rod coupled structure, web member 9 is made up of connecting link 24 and spheroid 25, one end of connecting link 24 is a bulb 26, the center of spheroid 25 has stepped hole, connecting link 24 is packed in the spheroid 25 and is made bulb 26 fall into the stepped hole of spheroid 25, spheroid is packed in the closo notch 28 of guide rail skeleton 1, and connecting link 24 joins with the door curtain made of cloth 5,27, the expansion of the door curtain made of cloth and fold motion and finished by web member.

When guaranteeing door curtain made of cloth duty, can not arbitrarily wave, also dispose stator 7 on the assembly and spacer 4 is locked.

Tension force when launching for satisfying the door curtain made of cloth and the power when folding are provided with elastic band 6 at stator 7 and 4 of spacers, and elastic band 6 is sewn between the door curtain made of cloth 5 and 27 door curtain made of cloth 5 and 27 is connected as a single entity.

This installs aboard that mounting means is directly to be fixed on the arc frame of aircraft windscreen, and lower limb has been avoided ejection channel like this above instrument panel, and emergency escape does not all have influence under any state.

When flying blind training, web member 9 to left movement, opens the door curtain made of cloth 5,27 along guide rail skeleton 1, thereby realizes the blocking-up front windshield transparent region purpose of sight line out of my cabin; When blind-flying training finishes, spur draw ring 13 and drive latches 10 motions, the door curtain made of cloth 5,27 folds rapidly under the effect of elastic band 6 on the guide rail right side, and recover in the visual field, dead ahead.

This device is installed on the windscreen arc frame, not in ejection channel, in flight training, when the palpus emergency ejection is disembarked, need not worry to the influence of ejection channel, can not produce additional injuries, so this type hidden-cockpit flight-hood and through canopy ejection lifesaving type adapt the pilot.
