Description
Technical field
The invention belongs to aircraft resistance umbrella system, the automatic drag parachute for throwing umbrella function is thrown after specially a kind of band is faulty
Laying mechanism.
Background technology
Drag parachute throwing puts device or does not misplace the throwing umbrella function after umbrella, or in order to realize on existing re-entry space vehicle
It throws umbrella function and increases hatchcover position sensor and corresponding electrical system.Both modes have lost aircraft platforms
Safety or the complexity for considerably increasing the occupied space of drag parachute system, weight and system, have lost aircraft
The performance of platform.
Invention content
The configuration of the present invention is simple is reliable, suitable for rarely needed and to space, weight and the high drag parachute of reliability requirement
In system.
The automatic drag parachute for throwing umbrella function throws laying mechanism after a kind of band is faulty, by blasting bolt (1), electric initiator (2),
Promotional implement (3), non-electrical propagation of explosion component (4), false locking device (5) form, blasting bolt (1) the connection housing construction and drag parachute
Cabin rear cover, false locking device (5) connection body bearing and drag parachute link, the distribution end of promotional implement (3) is by being threadably mounted at vacation
On locking device (5), the output terminal connection blasting bolt (1) of non-electrical propagation of explosion component (4) and the other end of promotional implement (3), non-electrically
Quick-fried component (4) input terminal connection electric initiator (2).
It is that piston adds the body of rod that promotional implement (3) is by promoting (521), promotional implement shell (522) two parts form to promote (521)
Composite structure, promotional implement shell (522) include the piston cylinder structure of gunpowder for one end closing, non-close end set six sides and screw thread with
False lock bolt (501) is assembled in false locking device (5).
False locking device (5) is by vacation lock bolt (501), self-locking nut (502), washer (503), bushing (504), tune gap washer
(505), inner ring (511), axle journal (512) composition；Vacation locks bolt (501) for hollow hexagon-headed bolt, turret head top surface open-blind hole,
There is the internal thread of certain depth in hole for installing promotional implement (3), vacation lock bolt (501) smooth bar part is provided with twice failure by shear
Slot, slot pitch are equal with inner ring (511) width；Bushing (504) is flange bushing, is installed in body bearing Double-ear-hole, at flange
On the inside of ears；Gap washer (505) thickness is adjusted to need to adjust according to assembling, vacation lock bolt (501) and self-locking nut (502), pad
Circle (503), bushing (504) adjust gap washer (505) cooperation that inner ring (511), axle journal (512) are installed on body bearing.
The technical issues of advantage and solution
The present invention is realized by setting false locking device in throwing lid and putting umbrella device：
1st, during aircraft flight in the air, in the case that drag parachute misplaces umbrella because of various factors, false locking device is in drag parachute
The lower automatic throwing umbrella of aerodynamic drag effect, ensures flight safety；
2nd, " vacation lock " change " true lock " when umbrella function is put in execution, drag parachute aerodynamic drag can be normal when ensureing normally to put umbrella
For aircraft.
False locking device only needs to increase parallel firing circuit all the way in traditional nonelectric product, it will be able to realize " therefore
Barrier-safety " function does not need to newly-increased drag parachute housing cover sensor and relevant logic judgment system, and system logic is simple, and institute
The functional priming system system that only relies on can be realized, and save structure space, the weight of sensor and its cable installation.

Specific embodiment
It is as follows that the umbrella device course of work is put in the throwing of this drag parachute：
It is powered first to two electric initiators 2 during normal work, electric initiator 2 works and lights 2 × 4 tunnel non-electrical propagation of explosion groups
Detonation wave is transferred to three blasting bolts 1 and promotional implement 3 by part 4, propagation of explosion component 4, and blasting bolt 1 and promotional implement 3 work asynchronously
Or by delay powder control by program successively work (promotional implement first work blasting bolt then work), promotional implement 3 will promote 521 and be pushed into
In vacation lock bolt 501, false locking device is made to switch to " true lock " state by " vacation is locked " state, false locking device can bear drag parachute at this time
Normal aerodynamic drag load.Three blasting bolt work, drag parachute housing rear cover is dished out, releases drag parachute, drag parachute passes through vacation
Aerodynamic drag is reached body by locking device, is aircraft.
Drag parachute because of various factors is accidentally released and generates pneumatic resistance by drag parachute when malfunction is aircraft flight in the air
Power directly jeopardizes flight safety, and drag parachute throwing at this time puts device and do not light a fire, and false locking device is in " vacation lock " state, when pneumatic resistance
When power is applied to by axle journal 512 and inner ring 511 on false lock bolt 501, the twice failure by shear slot on vacation lock bolt destroys, by
521 push-in vacation of distribution is not locked in bolts 501 in promotional implement 3, vacation lock bolt 501 cannot carry after failure by shear slot destroys, gas
Drag parachute will be pulled away from body by dynamic resistance, and drag parachute throws laying mechanism and performs throwing umbrella function automatically in the case where failure puts umbrella condition,
Realize flight safety.
