Abstract
The present invention is a kind of test section replacing options of continuous way transonic wind tunnel, the method is provided with steering gate (8) and isolating door (9) in the side of load wall, when needing to change test section (1), isolating door (9) is in load wall centre position, now, isolate with continuous way transonic wind tunnel residual circuit in room (2), change test section (1) and need only change in room (2) internal gas.When being tested, steering gate (8) is made in load wall centre position, so, whole closed loop flows back insertion, it is ensured that test is smoothed out.
Description
Technical field
The present invention is a kind of test section replacing options of continuous way transonic wind tunnel, belongs to continuous way transonic wind tunnel hole body
Structure.
Background technology
Continuous way transonic wind tunnel is a closed loop, and whole container reaches 1.5 ten thousand steres, and test section is located in room
It is internal.In room be section be circular tubular shell, be provided with oblong aperture in side in room.Test section is from this hole turnover in room
Outward, this hole needs to be sealed with gate in room.According to different test requirements documents, need to change test section, work as replacing
During test section, need to be vented the gas with pressure in loop, after the completion of to be tested section is changed, need again to whole wind-tunnel
Loop is suppressed, until the pressure that test needs.This process needs to consume a large amount of sources of the gas, and cost is very high.
The content of the invention
The present invention is exactly designed and provides a kind of continuous way transonic speed wind for deficiency present in above-mentioned existing apparatus
The test section replacing options in hole, its objective is that solving continuous way transonic wind tunnel gas wastes problem.Loop when realizing test
Insertion, when changing test section, loop isolation.
The purpose of the present invention is realized by following technical measures：
The test section replacing options of this kind of continuous way transonic wind tunnel, the test section (1) of the continuous way transonic wind tunnel
Positioned at continuous way transonic wind tunnel in room (2) inside center, front load wall (3), rear load are respectively arranged with room (2) two ends
Wall (4), has test runner (5) on front load wall (3) and rear load wall (4) respectively, it is characterised in that：In front load wall (3)
Come flow side (6) and rear load wall (4) go flow side (7) and be respectively arranged to the steering gate (8) of water conservancy diversion and isolation for damming
Door (9), steering gate (8) and isolating door (8) on a guide rail (10), when continuous way transonic wind tunnel it is in running order
When, former and later two steering gates (8) are docked with test runner (5) is tested, when test section (1) needs to change experimental piece,
Former and later two isolating doors (9) docks with test runner (5), will in room (2) two ends and other sections of continuous way transonic wind tunnel every
From and the gas pressure that keeps in continuous way transonic wind tunnel other sections.
The inventive method is provided with steering gate (8) and isolating door (9) in the side of load wall in order to save gas, when need
During test section (1) to be changed, isolating door (9) in load wall centre position, now, in room (2) and continuous way transonic wind tunnel
Residual circuit is isolated, and changes test section (1) and need only change in room (2) internal gas.When being tested, steering gate is made
(8) in load wall centre position, so, whole closed loop flows back insertion, it is ensured that test is smoothed out.

Specific embodiment
Technical solution of the present invention is further described below with reference to drawings and Examples：
Referring to shown in accompanying drawing 1～4, the test section replacing options of this kind of continuous way transonic wind tunnel, the continuous way is across sound
The test section 1 of fast wind-tunnel is respectively arranged with front load in 2 two ends of room positioned at continuous way transonic wind tunnel in 2 inside center of room
There is test runner 5 on wall 3, rear load wall 4, front load wall 3 and rear load wall 4 respectively, it is characterised in that：In front load wall 3
Come flow side 6 and rear load wall 4 go flow the steering gate 8 and isolating door 9 for damming that side 7 is respectively arranged to water conservancy diversion, water conservancy diversion
Door 8 and isolating door 9 are arranged on a guide rail 10, when continuous way transonic wind tunnel is in running order, former and later two water conservancy diversion
Door 8 dock and is tested with test runner 5, and when test section 1 needs to change experimental piece, former and later two isolating doors 9 are flowed with testing
Road 5 is docked, will other sections are isolated and keep other portions of continuous way transonic wind tunnel with continuous way transonic wind tunnel in 2 two ends of room
Gas pressure in section.
Forward and backward load wall is all that, by the structure of two ends steel plate and intermediate ribs plate weld, middle test runner 1 is length
It is square, front load wall 3 come flow side 6 and rear load wall 4 go flow side 7 hook structure be set, front load wall 3 flowing 6 He of side
Stream 7 end face of side that goes of load wall 4 arranges air-inflating mechanism afterwards, arranges guide rail 10, for 8 He of steering gate above hook structure
Isolating door 9 improves walking function and guide function, and when trystate, steering gate 8 goes to load wall centre bit along guide rail 10
Put, it is corresponding with test runner 5, now gas-flow closure is inflated, it is ensured that test runner 5 and the gas barrier between room 2, is entered
Row test, when testpieces is changed, steering gate 8 moves to side along guide rail 10, and isolating door 9 is moved to and load wall centre bit
Put, gas-flow closure is inflated, will other sections be isolated with continuous way transonic wind tunnel in room 2, it is ensured that other sections
Gas pressure.
Compared with prior art, this have the advantage that：
1., when changing testpieces, only need to change gas in chamber interior, saved the amount for changing test section gas, section
About cost；
2. isolating door (9) and steering gate (8) change convenient and reliable, it is ensured that experimental flow field is unaffected；
3. will isolate with other sections in room (2), and save deflation and inflationtime, improve work efficiency.
