Abstract
The utility model relates to an emergency parachute device for helicopters, which is provided with a rectification cover arranged above a propeller, wherein the cover is divided into a left and a right compartments by a baffle plate which is vertically arranged in the cover; a parachute wing is arranged in the left compartment, a parachute wing controller, an electromagnetic lock for controlling covers of the compartments, an accumulator for supplying an electrical source and a wireless receiver are arranged in the right compartment, the parachute wing controller is formed by connecting a motor with a winch via a worm wheel and worm drive mechanism, and the wireless receiver is used with a wireless remote control transmitter in a driving chamber. The utility model provides an aerial flight salvation device for the helicopters, and the safe landing of the helicopters in the state of aerial loss of control can be realized.
Description
The utility model relates to a kind of helicopter escape chute falling unit, is arranged on helicopter propeller propeller hub top, is used for the emergency safety landing after the helicopter flight process is got into danger.
Present helicopter in case break down or round outside destroy, loses flight and hover capabilities, will fall at once and cause fatal crass's tragedy.Although occurred the technology that chaufeur launches escape, only be confined to military attack helicopter.Moreover the price of helicopter itself is very expensive, adds when body crashes and may even chaufeur can be survived, also cause heavy losses to the destruction of surface facility generation.The safety measure of most existing helicopters mainly is to strengthen the anti-crash ability of alighting gear, chassis and seat passively, but can only play a role when low-latitude flying.And significantly increase body weight, and will reduce load-carrying ability, have a strong impact on airworthiness.Therefore, helicopter to reach body light, safe, increase the purpose of cost not significantly again, be to need a significant problem solving at present.
The purpose of this utility model is exactly the problems referred to above that exist at existing helicopter, is started by chaufeur and provide a kind of, opens umbrella wing slip Xiang automatically, and the helicopter escape chute falling unit of ground safe falling is selected in control.
The technical scheme that realizes above-mentioned purpose is: a kind of helicopter escape chute falling unit, has the fairing that is arranged at the screw propeller top by strut bar, there is the perpendicular dividing plate of putting to be divided into left and right two cabins in this cover, pack in its left cabin through umbrella wing rope with the fairing bonded assembly umbrella wing, be provided with in its right cabin through worm and worm wheel and make the electrical motor that cooperates and capstan winch, the electromagnetic lock formed by electromagnet and retracing spring and dead bolt, the storage battery of electric energy be provided and be serially connected with radio receiver and source switch in the control circuit for electrical motor and electromagnet; On capstan winch, oppositely twine two umbrella wing tricing line mutually, dispose pull switch with source switch and shake hands and be combined with the radio telecommand emitter to be arranged in the operator's compartment of helicopter with radio receiver; On fairing, be provided with through left side elasticity folding bonded assembly hatchcover, be provided with the lock frame in this hatchcover below the right side and match with the dead bolt of electromagnetic lock.
The utility model has remedied existing helicopter does not have the initiatively defective of safety measure, can realize the helicopter safe falling of unpowered state aloft, has solved the safety control problem of helicopter substantially.
Accompanying drawing is this helicopter escape chute falling unit structural representation.
The utility model is described in further detail below in conjunction with drawings and Examples.
Provide as accompanying drawing, radio telecommand emitter 1 of this device and switch handle 2 are arranged in the operator's compartment; Strut bar 3 is suspended in the hollow space of propeller hub, and the lower end is connected with body, upper end fixed pedestal fairing 9; Cover body is divided into umbrella cabin and control cabinet, separates with the perpendicular dividing plate of putting 6, is connected with fairing with the end of elasticity folding 11 with hatchcover 12, is provided with a lock frame 13 at the hatchcover other end; To dead bolt be in and the cooresponding position of lock frame by the electromagnetic lock 18 that electromagnet, retracing spring and dead bolt the are assembled into control cabinet of packing into; Cooperate with the worm gear 17 of capstan winch 16 input shaft ends by the worm screw 5 of electrical motor 4 output axle heads and to be assembled into umbrella wing controller, the control cabinet of packing into; With radio receiver 8, source switch 7, storage battery 19 other position of control cabinet of packing into; Umbrella cabin on the left of the umbrella wing 10 is packed into, its umbrella wing rope 14 is fixedly connected in the fairing, and two umbrella wing tricing line 15 oppositely are wound in two grooves of capstan winch 16 mutually; To pass the power supply input socket that source switch 7 inserts radio receiver 8 by the power lead that storage battery 19 is drawn, the forward and backward power lead of the power lead of electromagnetic lock 18 and electrical motor 4 is inserted three power supply output sockets of radio receiver 8 respectively, fairing 9 is passed in the backguy of source switch 7 to be entered operator's compartment and switch handle 2 along strut bar 3 and is connected, rotation hatchcover 12, with dead bolt the lock frame is pinned, hatchcover is fixed.
The working process of this device is: before helicopter took off, chaufeur Drawing switch handle 2 turned on the power switch 7, and radio receiver 8 is ready; Chaufeur is held radio telecommand emitter 1 and is sent enabled instruction when in danger, after receiver 8 is received signal, connect electromagnet and attract the dead bolt retraction, hatchcover 12 is opened under the effect of elasticity folding 11, drives the umbrella wing 10 and pops up, wait the umbrella wing to launch fully after, chaufeur can be by handling radio telecommand emitter 1 telemotor 4 forward or reverse, drive capstan winch 16 and rotate, extraction parachute wing tricing line 15 is handled umbrella wing slip Xiang, and the control helicopter is selected the ground safe landing.
