Abstract
The invention discloses a kind of extraction parachute device for measuring force based on aircraft, including clamping plate（1）, pedestal（2）And limited post（3）, three limited posts（3）Distribution triangular in shape, positioned at clamping plate（1）With pedestal（2）Between, and connecting cleat（1）With pedestal（2）；Pedestal（2）It is interior to be equipped with foil gauge；Rope band passes through three limited posts, one end connection extraction parachute release device of rope band, other end connection extraction parachute.Extraction parachute device for measuring force of the present invention can not only measure and record the force value of extraction parachute system generation in real time, but also not interfere with the release procedure of extraction parachute system, and the extraction parachute dynamometry that product is dropped for the new refitting of subsequent adaptation provides scheme.
Description
Technical field
It is specifically that a kind of simulation extraction parachute traction is empty the invention belongs to implement the technical field of extraction parachute test aboard
Throwing is disembarked process, is realized that extraction parachute system is connected with airplane floor, and is measured the device of force value under extraction parachute working condition.
Background technology
The large transport airplane that the country is newly ground at present, it is empty using ripe traction when product is dropped in adaptation large-tonnage refitting
Throwing technology；And the main technique methods for drawing air-drop technology are to form tractive force using extraction parachute prerequisite activity, pull refitting
Air-drop product is disembarked, and realizes the function of traction air-drop.Extraction parachute system work process can generate the power opposite with vector
Value reduces the flight efficiency of aircraft；And extraction parachute system is put in throwing, parachute-opening, during steady operation, it is easily dry by aircraft turbulent flow
It disturbs, influences aircraft safety.So it is badly in need of a kind of simultaneously measuring the device of force value for testing extraction parachute at present.
The content of the invention
It is an object of the invention on the premise of aircraft is not changed, for the course of work of extraction parachute system, provide one
Easy to use, simple in structure, the safe and reliable device for measuring force of kind can simulate refitting air-drop product using traction air-drop to greatest extent
The operating mode disembarked gathers test data and information, for studying and judging extraction parachute working state of system to aircraft control and stability and using machine
Influence.
Realize the object of the invention technical solution be：A kind of extraction parachute device for measuring force based on aircraft, including clamping plate,
Pedestal and limited post, three limited post distributions triangular in shape, between clamping plate and pedestal, and connecting cleat and pedestal；Pedestal
It is interior to be equipped with foil gauge；Rope band passes through three limited posts, one end connection extraction parachute release device of rope band, other end connection traction
Umbrella.Described foil gauge one end is arranged on base interior, the conducting wire of other end connecting test display device.The clamping plate passes through screw thread knot
Structure is fastened with connector.
Compared with prior art, the present invention its remarkable advantage：（1）Extraction parachute device for measuring force of the present invention both can in real time measure simultaneously
The force value that extraction parachute system generates is recorded, and does not interfere with the release procedure of extraction parachute system, is that the new refitting of subsequent adaptation is empty
The extraction parachute dynamometry of operation product provides scheme.（2）Device for measuring force of the present invention has test frequency height, dynamic response is fast, tested
Journey and release process influence the advantages that small to agent structure.
Description of the drawings

Fig. 2 is extraction parachute device for measuring force external structure schematic diagram of the present invention.
Fig. 3 is the work structure diagram of extraction parachute device for measuring force of the present invention.
Specific embodiment
The present invention can be applied to other fields simultaneously, and the environment for predominantly needing dynamic measurement, force value larger does not destroy soft
Property load-carrying construction body on the premise of, side compression type tension is used to implement the force value that measures needed for high frequency measurement.
In simulation resets the connection structure disembarked of air-drop product traction air-drop, by device for measuring force be connected on release device and
Between extraction parachute system.In extraction parachute experiment is carried out, the function of acquisition tractive force is realized by device for measuring force.
With reference to Figure of description, the invention will be further described.
With reference to Fig. 1, extraction parachute device for measuring force is realized tight with the connection of refitting air-drop product simulation part by helicitic texture
Gu.
With reference to Fig. 2, extraction parachute device for measuring force realizes the washability of installation direction by connecting transition piece.Three limited posts 3
Distribution triangular in shape, between clamping plate 1 and pedestal 2, and connecting cleat 1 and pedestal 2；Foil gauge is equipped in pedestal 2；Rope band is worn
Cross three limited posts, one end connection extraction parachute release device of rope band, other end connection extraction parachute.
It is the three spindle-type stress main bodys that three limited posts make main body with reference to Fig. 3, inside extraction parachute device for measuring force, rope band passes through
Three limited posts, one end connection extraction parachute release device, one end connection extraction parachute.The tension generated on rope band is transferred to three spindle-type
The purpose of dynamometry is realized in stress main body, the deformation that three spindle-type stress main bodys generate by foil gauge.
Device for measuring force has the external test display device of cable, can monitor, read test data, and store in real time.
Device for measuring force of the present invention has fast test frequency height, dynamic response, test process and discharges process to agent structure
Influence the advantages of small.
