Description
Technical field
The utility model is related to a kind of mounting brackets of antispin parachute, belong to field of airplane structure.
Background technology
Antispin parachute system is a kind of emergent safety dress for ensuring new model aircraft stall, spin flight test and carrying out safely
It puts.Aircraft enters stall, spin flight state, when Aviatrix can not be changed with control surface, can enable antispin parachute system,
The power and torque generated using antispin parachute is made rapidly aircraft stop rotating and is restored to regular flight condition from runaway condition.It is existing
Have and the more of helicopter tail rotor is studied in technology, study the less of antispin parachute, study the less of antispin parachute stent.Anti- tail
Umbrella frame is revolved as the bridge between connection antispin parachute and housing construction, should ensure that the load of antispin parachute is smoothly transmitted to
On housing construction, ensure that existing aircraft body structure does not need to larger repacking again.
Utility model content
The purpose of this utility model is to solve problems of the prior art, and providing one kind is ensuring existing airframe
Under the premise of structure does not need to larger repacking, the antispin parachute load of antispin parachute being smoothly transmitted on housing construction is installed
Stent.
In order to achieve the above object, the utility model adopts the following technical solution：A kind of antispin parachute mounting support structure,
Mainly include support connector, umbrella Hold Beam, pull rod and load bearing；The support connector is fixed on rear body by stiffened skin
On, the umbrella Hold Beam front end is connect with rear body end frame, and rear end is connected by load bearing with Pao San mechanisms；The pull rod is symmetrical
The both sides of umbrella Hold Beam are set to, both ends are connect by the rod head being spirally connected therewith with support connector, load bearing respectively.
Further, stent partition board is further included, is connect among the stent partition board by bolt with umbrella Hold Beam, both ends part
It is not connected by stent partition board connector with pull rod.
Further, end frame reinforcing plate is further included, the end frame reinforcing plate is set to umbrella Hold Beam front end, for strengthening umbrella cabin
Beam front end and the connection of rear body end frame.
Further, the end frame connection sheet being set on support connector is further included, the end frame connection sheet is solid for connecting
Fixed end frame.
From above-mentioned connection relation it is found that the X of umbrella to load by umbrella Hold Beam and the pull rod shared of both sides, Z-direction load and
Eccentricity is undertaken by the pull rod of both sides, and Y-direction load is transmitted from intermediate umbrella Hold Beam to rear body end frame, the eccentricity of Y-direction load
It is transmitted respectively to central sill and fuselage skin in the form of tension and compression from umbrella Hold Beam and pull rod, smoothly realizes umbrella load to housing construction
It transmits.
The utility model compared with prior art, has the following advantages that：It may be applicable to carry out anti-tailspin to take a flight test requirement
All kinds of twins（It also can be used for single-engine plane by reequiping）, construction access accessibility is good, can meet structural modification
It is required that it and changes smaller.

Specific embodiment
It should be noted that in the present embodiment, the nouns of locality such as " left and right " are described according to shown in attached drawing, are not
Limitation to the utility model.
1-4 is described further the utility model below in conjunction with the accompanying drawings：As shown in Figs 1-4, antispin parachute supporting structure
By stiffened skin 1, support connector 2, rod head 3, end frame reinforcing plate 4, end frame connection sheet 5, stent partition board 6, load bearing 7,
Umbrella Hold Beam 8, stent partition board connector 9 and pull rod 10 form, and umbrella Hold Beam front end is connect by bolt with rear body end frame 11, passes through end
Frame reinforcing plate 4 is strengthened, and rear end is connected by load bearing 7 with Pao San mechanisms；Fixing end frame connection sheet 5 is installed on support connector 2,
End frame connection sheet 5 is used to connect fixing end frame 11；Pull rod 10 is combined into one with rod head 3 by screw thread（With
1Cr18Ni9Ti-d1.2 fuse is locking）, later both ends pass through the bolt support connector 2 with being fixed on stiffened skin 1 respectively
And load bearing 7 connects；Umbrella cabin（It is not shown in figure）Umbrella cabin mounting bracket is separately fixed at by bolt（It is not shown in figure）And
It on load bearing 7, is connect among stent partition board 6 by bolt with umbrella Hold Beam 8, both ends pass through stent partition board connector 9 and pull rod
10 are connected.
Installation steps：
1）Antispin parachute cord lock hook position of action point according to totally providing determines that pull rod 10 and umbrella Hold Beam 8 install intersection point position
It puts；
2）According to three-dimensional maximum maneuvering load, intensity, rigidity and stability requirement are considered, in umbrella Hold Beam 8 or so two
Side is arranged symmetrically 2 pull rods 10, and 10 both ends of pull rod are handed over by rod head 3 with support connector 2, the single ears of load bearing 7 respectively
Fork connection, support connector 2 is fixed on by the riveting of stiffened skin 1 on rear body, so as to which the load on antispin parachute cabin is smooth
It passes on fuselage；
3）8 structure of umbrella Hold Beam and biography are determined according to distance and three-dimensional maximum maneuvering load between end frame 11 and installation intersection point
Power route, 8 both ends of umbrella Hold Beam are connect respectively by bolt with end frame 11 and load bearing 7；
4）In order to ensure the smooth posting of structure, support connector 2, rod head 3, pull rod 10,7 main load path of load bearing
Should it is most short and pass through umbrella Hold Beam install intersection point.Since pull rod 10 is longer, guarantor is connect with stent partition board 6 by stent partition board connector 9
Demonstrate,prove structure lateral stability；
5）Finally, with bolt by stent partition board connector 9 and stent partition board 6, support connector 2 and rod head 3, rod head
3 fix with load bearing 7, and rear body and antispin parachute mounting bracket are linked to be an entirety, ensure that the load of antispin parachute is suitable
Profit is transmitted to housing construction.
Above-described embodiment is only the preferred embodiment of the utility model, is not the limitation to the utility model, any
The deformation or amplification done on the basis of the utility model, it is within the protection scope of the present utility model.
