Description
Technical field
The present invention relates to a kind of integrated form undercarriage control priority acccess control switch, belong to aircraft system design field.
Background technology
The multifunctional integrated direction of present generation aircraft control design case forward is developed, and the utilization of electromechanical integration technology can realize Various Complex function, but system complexity improves the most accordingly, increases design difficulty, improves manufacture maintenance cost.Aircraft pneumatic system is to various ways such as undercarriage control control, Organic Electricity control, Mechanical course, mechanical-electrical-hydraulic integration controls at present.The complex control forms such as Electromechanical Control, mechanical-electrical-hydraulic integration control, the cable arranged in needing passenger cabin, switch, pipeline arranges valve and has jointly acted on undercarriage control control, take the bigger space of aircraft and weight, control the more complicated reliability in loop poor.
Summary of the invention
In order to overcome drawbacks described above, it is an object of the invention to solve ensure diversified functional while, promote system reliability, which employs purely mechanic control form, complete to control the control of operation of landing gear gas circuit only with a purely mechanic part, volume and weight is less, and simple and reliable, thus provides a kind of integrated form undercarriage control priority acccess control switch.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of integrated form undercarriage control priority acccess control switch, rear deck undercarriage control control switch be divided in receipts, put down, neutral three positions, it is provided with air inlet ozzle and front deck undercarriage control and controls ozzle I that switch is connected, ozzle II, ozzle III, the ozzle IV being connected with undercarriage control pressurized strut, ozzle V.
Above-mentioned air inlet ozzle, ozzle I, ozzle II, ozzle III, ozzle IV, ozzle V gas circuit connect through rear deck undercarriage control and control the housing of switch and internal valve structure connection.Complete undercarriage control and the function of rear deck control front deck.
Control to be provided with locking plate between the handle of switch and housing at rear deck undercarriage control, handle is provided with latch.Locking plate is provided with three draw-in grooves to receivable upper, neutral, extended position, coordinates with latch and handle is fixed on relevant position, prevent landing gear switch upper handle from being touched by mistake.
Rear deck undercarriage control controls to be provided with gas vent on switch.
Rear deck undercarriage controls to switch when neutral position, and nose-gear is controlled switch and directly connects with undercarriage actuating cylinder by this switch internal structure, and the position that front deck undercarriage controls to switch obeyed by undercarriage；Rear deck undercarriage controls switch not when neutral position, internal structure disconnects the connection of nose-gear switch and undercarriage actuating cylinder, being connected with undercarriage actuating cylinder by self ozzle, now the position that rear deck undercarriage controls to switch only obeyed by undercarriage, and it is invalid that front deck undercarriage controls switching manipulation simultaneously.
Beneficial effects of the present invention:
The present invention uses a kind of purely mechanic integrated switch, complete backseat pilot to undercarriage stowage, neutrality, put down the control of three positions, and have safety to prevent from packing up or putting down maloperation, and ensure the backseat pilot preferential front seat man control to undercarriage control.The present invention is only with a purely mechanic integrated and product for band priority control function, both meet aircraft and control the demand of several functions, significantly reduce again the complexity of system, save aircraft installation and safeguard space and manufacturing cost, enhance reliability and the maintainability of aircraft.
Accompanying drawing explanation
Fig. 1 is that in the present invention, rear deck undercarriage control controls switch neutral condition schematic diagram；
Fig. 2 is that in the present invention, rear deck undercarriage control controls to switch non-neutral condition schematic diagram；
Fig. 3 is that in the present invention, rear deck undercarriage control controls switch external structural representation.
Detailed description of the invention
1,2,3 describe the present invention below in conjunction with the accompanying drawings:
A kind of integrated form undercarriage control priority acccess control switch, rear deck undercarriage control control switch 11 be divided in receipts, put down, neutral three positions, it is provided with air inlet ozzle 1 to control with front deck undercarriage control to switch 12 ozzles I 2 being connected, ozzle II 4, ozzle III 6, the ozzle IV 3 being connected with undercarriage control pressurized strut 13, ozzle V 5.
Above-mentioned air inlet ozzle 1, ozzle I 2, ozzle II 4, ozzle III 6, ozzle IV 3, ozzle V 5 gas circuit connect through rear deck undercarriage control and control the housing of switch 11 and internal valve structure connection.
Control to be provided with locking plate 23 between the handle 8 of switch 11 and housing 24 at rear deck undercarriage control, handle 8 is provided with latch 22.
Rear deck undercarriage control controls to be provided with gas vent 7 on switch 11.
Fig. 1 is that rear deck undercarriage controls to switch in neutral position, and front deck undercarriage controls switch at extended position.High pressure cold enters enclosure interior by the air inlet ozzle 1 of housing central section, under the effect of internal shunt valve, cold air enters nose-gear by the ozzle II 4 in the middle of housing side and controls switch, nose-gear controls the cold air of switch output and enters enclosure interior by ozzle I 2 again, ozzle I 2 is connected by internal shunt valve with ozzle IV 3, cold air puts down chamber from ozzle IV 3 entrance undercarriage actuating cylinder, makes gear down；Pressurized strut is received the cold air of epicoele and is entered air through the air vent of ozzle V 5, ozzle III 6 and front deck landing gear switch.
Fig. 2 is that rear deck undercarriage controls to switch at extended position, and front deck undercarriage controls switch in retracted position.Housing interior structure acts on side valve jointly by the ozzle I 2 being connected with front deck undercarriage control switch, ozzle II 4, ozzle closure, is connected with ozzle IV 3 by air inlet ozzle 1, and ozzle V 5 connects with gas vent 7.Cold air enters and puts down chamber through air inlet ozzle 1, ozzle IV 3 in undercarriage control pressurized strut, makes gear down；Folding and unfolding chamber cold air enters air through ozzle V 5, gas vent.The operation that now nose-gear controls in switch receipts is invalid, and undercarriage is only obeyed rear deck undercarriage and controlled the operation of switch.
Fig. 3 is that rear deck landing gear switch handle is locked in neutral position.Locking plate is fixed on housing, handle is inlayed and is mounted with latch.Landing gear operational completes, and is held in after on handle, power is cancelled, and the latch on handle slides axially along handle under the effect of handle inner spring power, just inlays in the groove of locking plate relevant position, by rear deck undercarriage handle lock in relevant position.When carrying out operation of landing gear operation again, need to exert oneself to promote handle vertically to housing direction, latch, under the effect of handle power, overcomes spring force to slide to the groove direction leaving locking plate.Latch leaves the groove of locking plate, and handle just can rotate upwardly and downwardly, and carries out undercarriage control operation.
The present invention has started aircraft cold gas system and the beginning of landing-gear system multifunctional unit priority acccess control mechanical switch, provides example and reference for follow-up aircraft system control design case.
