Description
Technical field
This utility model relates to field of mechanical technique, specifically refers to a kind of light-duty stealthy electromagnetism and unlocks drag parachute housing structure.
Background technology
Drag parachute is also drag parachute, is used to reduce the umbrella instrument of sliding running velocity degree during aircraft landing.Generally by main chute, draw
Pilot chute and umbrella bag etc. form, and are contained in the umbrella cabin of airplane tail group.In the sliding race of aircraft landing, pilot guidance open umbrella hatch door,
First extractor parachute opens, and is pulled out by umbrella bag, opens main chute, and canopy is drawn out after opening and can increase air drag, pulls backward and flies
Machine, is allowed to slow down, and shortens ground run distance.
The throwing umbrella structure of existing aircraft is complex, passes through the frame for movements such as pull bar more and realizes umbrella hatchcover with air pressure driving
Unblock, invisbile plane then use pressurized strut by Pao San mechanism release fuselage surface, pull bar, pressurized strut etc. all take bigger
Space and weight indicator in machine, the manufacture for aircraft provides bigger restriction, when the most existing throwing umbrella structure is safeguarded, needs
Want surface power supply, very inconvenient.
Utility model content
The purpose of this utility model is to provide one can effectively save in weight and machine while possessing stealthy function
Space and the light-duty stealthy electromagnetism being easily maintained unlock drag parachute housing structure.
This utility model is achieved through the following technical solutions: a kind of light-duty stealthy electromagnetism unlocks drag parachute housing structure, including
It is arranged on the sawtooth lid of body, torsion support and the first electromagnetism unlocking device, below described sawtooth lid, is fixedly connected with umbrella cylinder,
The opening of described umbrella cylinder front end is provided with umbrella cover, and described umbrella cover bottom is connected with umbrella cylinder by Torque force hinge joint, umbrella cover top
Be provided with the second latch hook, described sawtooth lid bottom be additionally provided with the first latch hook with the use of the second electromagnetism unlocking device；Described umbrella
Fixing with torsion support at the bottom of the cylinder of tube rear end and be connected, described torsion support is provided with and the first electromagnetism unlocking device with the junction of umbrella cylinder
With the use of the first latch hook.
The operation principle of the technical program is, umbrella cylinder is connected to sawtooth lid inner surface, and uses two electromagnetism to unlock
Device coordinates torsion mechanism to pin umbrella cylinder and umbrella cylinder bonnet respectively so that umbrella cylinder is embedded in body, and drag parachute is pressed in by umbrella cover
In umbrella cylinder.When needs put umbrella, the first electromagnetism unlocking device and the first latch hook unclamp, and umbrella cylinder ejects fuselage under torsion mechanism effect
Surface, afterwards, the second electromagnetism unlocking device and the second latch hook unclamp so that umbrella cabin bonnet is opened, umbrella cylinder internal resistance umbrella ejects, it is achieved
Throw umbrella action.The most just achieve and use the electromagnetism unlocking device that small size, integrated level are high to replace machine more in tradition drag parachute housing
Tool parts.
Original state drag parachute is placed in umbrella cylinder, and umbrella cylinder closes with umbrella cover, and sawtooth lid Guan Bi is hidden in body, turns round
Power support fixes, by acting on, the umbrella cylinder being connected with sawtooth lid, the pull strength outwardly opened provided for sawtooth lid, and
Use the first electromagnetism unlocking device and the first latch hook to lock, limit sawtooth lid and open, keep sawtooth lid to outwardly open
Trend.
The Torque force hinge joint of umbrella cover and umbrella cylinder junction, provides the pull strength opened for umbrella cover, but the second latch hook with
Locking of second electromagnetism unlocking device is restricted, makes umbrella cover closely and the laminating of umbrella cylinder, and umbrella cover is at Torque force hinge joint simultaneously
Under effect, the trend stayed open.
When drag parachute opened by needs, the first electromagnetism unlocking device and the first latch hook are decontroled, and sawtooth lid drives umbrella cylinder outside
Opening, the second electromagnetism unlocking device and the second latch hook are decontroled subsequently, and umbrella cover is opened, and the drag parachute being compressed in umbrella cylinder has ejected
Throw umbrella.
After drag parachute reloads umbrella cylinder, make the second electromagnetism unlocking device and the locking of the second latch hook, i.e. ensure that umbrella cover closes
Close, and make the first electromagnetism unlocking device and the locking of the first latch hook, even sawtooth lid is hidden in body again, complete to safeguard.
For preferably realizing this utility model, further, the inside of described torsion support and Torque force hinge joint is mounted on
Torque spring.
For preferably realizing this utility model, further, the material of described sawtooth lid is aluminium alloy.
For preferably realizing this utility model, further, it is provided with sealing rubber ring between described umbrella cylinder and umbrella cover.
For preferably realizing this utility model, further, described first electromagnetism unlocking device and the second electromagnetism unlocking device are
The electromagnetism unlocking device that model is identical, and it is each equipped with hand switch.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) this utility model assembly in stealthy lid has possessed ejection, has thrown the function of umbrella, and a whole set of structure is all hidden in
In fuselage surface, sawtooth lid is coordinated to meet stealthy requirement；
(2) this utility model drives parts by decreasing the tradition drag parachute housing such as pull bar and pressurized strut, little with volume
The high electromagnetism unlocking device of integrated level coordinates novel structure design to realize throwing umbrella action, and volume is little, lightweight, easy to maintenance and not
Affect aircraft Stealth Fighter；
(3) this utility model uses two same model and can unlock at the electromagnetism of manual unlocking latch hook under powering-off state
Device, power supply, maintenance are conveniently.
