Abstract
A kind of design of air speed pipe clamp is the utility model is related to, discloses a kind of static pressure of observable connection reliability/total head one air speed pipe clamp, which is effectively integrated by static pressure/total head air speed pipe clamp, and ensure that static pressure and the isolation test of total head；Whether in place using the bucket wall of glass steel material, fixture installation can be directly observed when mounted.
Description
Technical field
The present invention relates to a kind of design of air speed pipe clamp, more particularly to a kind of static pressure of observable connection reliability/complete
The integral air speed pipe clamp of pressure.
Background technology
Atmosphere data acquisition device of the pitot as machine/missile-borne air data system, is widely used in various aviations and flies
On row device.The static pressure that aircraft is measured according to pitot can calculate the flying height of aircraft itself, and be surveyed according to pitot
The total head obtained can calculate the flying speed of aircraft.Before ground test is carried out to air data system, by pressure altitude mould
Intend the static pressure hole of device and full pressure hole is respectively connected to the static pressure hole and full pressure hole of air speed pipe clamp by gas circuit pipe, then by pitot
Fixture is reliably connected to pitot.During test, pressure altitude simulator simulating atmospheric environment exports corresponding static pressure and complete
Pressure value, is conducted to pitot by gas circuit pipe and air speed pipe clamp, forms the excitation to air data system, to realize to big
The performance verification of gas data system.
Existing air speed pipe clamp generally uses two sections of metal material fixtures, wherein one section is used for the test to static pressure, it is another
Section is used for the test to total head.Not only quality is heavy for such a fixture, it is cumbersome to connect, but also easily occurs sealing ring in connection procedure and block up
The firmly situation of pitot static pressure hole, causes the test crash of manual operation reason.
The content of the invention
The object of the invention：According to the pitot features of shape of certain model, a kind of the quiet of observable connection reliability has been invented
Pressure/total head one air speed pipe clamp.
Technical solution of the present invention：A kind of static pressure of observable connection reliability/total head one air speed pipe clamp, its feature exist
In main body respectively has a pressure hole into tubbiness, front end and side, and wherein side pressure hole is static pressure hole 2, and front end pressure hole is complete
Hole 1 is pressed, isolation elastic tape 3 is installed between static pressure hole 2 and full pressure hole 1, and closing rubber ring 4 is installed in body rear port
Side, dead ring 5 are installed on the outside of body rear port.
The jig main body uses glass steel material.
The isolation elastic tape 3, closing rubber ring 4 are close to the outer wall of tested pitot 6, form total head room 9 and quiet
10 two independent confined spaces of pressure chamber.
Tested pitot full pressure hole 7 and tested pitot static pressure hole 8 on the tested pitot 6 is only positioned at two respectively
Vertical is closed interior.
The side pressure hole is static pressure hole 2, front end pressure hole for full pressure hole 1 respectively with the pressure altitude in test equipment
The static pressure output of simulator is connected with total head efferent duct.
Advantageous effect of the invention
Static pressure/total head air speed pipe clamp is effectively integrated by the invention, and ensure that the isolation of static pressure and total head is surveyed
Examination；Whether in place using the bucket wall of glass steel material, fixture installation can be directly observed when mounted.

Embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, this fixture, main body respectively has a pressure hole into tubbiness, front end and side, and wherein side pressure hole is
Static pressure hole, top pressure hole are full pressure hole, are respectively used to static pressure output and the total head efferent duct of connection pressure altitude simulator.Every
It is installed on from elastic tape 3 between static pressure delivery outlet and total head delivery outlet, closes rubber ring 4 and be installed on the inside of body rear port,
For the aeroseal with air speed tube wall.Dead ring 5 is installed on the outside of body rear port, for by air speed pipe clamp and air speed
Pipe is reliably connected.
As shown in Fig. 2, after air speed pipe clamp is installed to tested pitot, its structure is as shown in Figure 2.Rolling clamp is tight
Gu clamp can be installed on tested pitot by ring 5, isolation elastic tape 3, closing rubber ring 4 are close to tested pitot 6
Outer wall on, form total head room 9 and 10 two independent confined spaces of plenum chamber, and the tested pitot on tested pitot 6
Full pressure hole 7 and tested pitot static pressure hole 8 respectively positioned at two it is independent it is closed in, therefore can accomplish not do mutually between the two
Disturb.
Whether in place in addition, this fixture uses the bucket wall of glass steel material, fixture installation can be directly observed when mounted, no
As for the situation for elastic tape occur and blocking tested pitot static pressure hole.
According to tested pitot features of shape, position and the size of rational fixture length and two elastic tapes are calculated,
It can make to form two independent confined spaces between pitot and fixture after installation, to realize air speed pipe clamp static pressure/total head
Integrated design.
