Working principle
One pressure sensor is installed respectively on trailing edge leading portion, trailing edge middle section and trailing edge back segment first, when installation should
Pay attention to easily leading to when fractureing if pressure sensor conducting wire turning radius is too small, it should conducting wire one end first be penetrated sensor installation
In through slot below hole, then sensor screwed in into sensor mounting hole；Next elastic trailing edge covers on trailing edge middle section, it should infuse
Elastic trailing edge length of anticipating should be greater than segment length in trailing edge, because both ends need to reserve certain surplus toward backrush on sealing ring, set
A size sealing ring appropriate is inserted in respectively before and after trailing edge middle section after good elasticity trailing edge, and elastic trailing edge both ends are existed toward backrush
On sealing ring, the sealing ring for rolling up elastic trailing edge is pushed into the groove of elastic trailing edge, is rolled up when pushing away；Then three sensors are led
Line is smoothed out with the fingers to be pierced by from trailing edge back segment together, and trailing edge leading portion, trailing edge middle section, trailing edge back segment are linked together with screw, sensor
Piezometric surface upward, three conducting wires pass by linkage section, water hole support construction connection data collecting instrument, computer, air compressor machine, pressure control
After device processed and snorkel connect, snorkel is passed by water hole support construction, linkage section, forms Liang Ge branch with threeway, and one point
Branch is inserted into the venthole in tail skirt middle section inflates for elastic trailing edge, send in another branch insertion main paragraph for head cavitation device
Gas；Main paragraph, three trailing edge sections, linkage sections are linked together with screw finally, entire model is fixed on water hole support knot
On structure.
When model length is larger, it is contemplated that improve support stiffness, reduce head amount of deflection, while accomplishing again anti-under water
The material of main paragraph is selected as aluminium alloy by rust, and trailing edge leading portion, trailing edge middle section, trailing edge back segment, linkage section material be selected as it is stainless
Steel；In view of cavity closure brings greater impact, sensor mounting hole selects fine thread to enhance connective stability；Elastic tail
The material of edge is the preferable butyl rubber of linear degree.
The main paragraph removed except cylindrical section is connected first；Secondly trailing edge section is connected, cylindrical section and trailing edge section
It is connected, is inserted in from the front of linkage section；Then force balance head is fixed on balance adapter, snorkel access elasticity
Trailing edge inside and main body g. slice header；Finally linkage section is covered in the tail portion of force balance, conducting wire is pierced by connection inside linkage section
On data collecting instrument.
It in this specific embodiment, is dynamometry by survey buckling due to measurement function, so some structures are changed,
Corresponding stress condition is also changed.In this specific embodiment, linkage section is longer, and trailing edge section does not stress, so
In view of reducing cantilever beam weight, raising support stiffness reduces head amount of deflection, while accomplishing underwater antirust again, trailing edge section
Material is selected as aluminium alloy, other construction materials are constant.
When on-test, model is installed first, and pressure controller is threaded to closed state, and gas is then full of in air compressor machine
Body can be tested according to working condition requirement.If necessary to generate ventilated supercavitation, then slow rotation pressure controller 8- is needed
1, if necessary to change the deformation state of elastic trailing edge, then slow rotation pressure controller 8-2 is needed, so that elastic trailing edge is slow
It deforms, observation pressure controller registration prevents excessive deformation from causing elastic trailing edge damaged.Observation pressure sensor measures
Pressure data, the drag data that observation force balance measures, analysing elastic trailing edge completely cut off tail portion jet stream, reduce skidding forces, improve
The function of stability.
