Abstract
The utility model discloses a device for balance impact load is experimental with wind -tunnel tail gas, including test module, supporting mechanism and joint, the supporting mechanism is installed and is surpassed the section of expanding in the wind -tunnel, test module passes through connect detachably install in on the supporting mechanism. When the wind -tunnel goes on normally testing, utilize the tail gas in the supersonic speed diffuser, it is experimental to carry the impact load who carries out the balance. Utilize this device can improve wind -tunnel test efficiency, reduce economic cost.
Description
Technical field
The utility model relates to a kind of balance scragging device, mainly this device is installed on wind-tunnel supersonic speed diffuser, while wind-tunnel carries out normal assays, can utilize the tail gas in supersonic speed diffuser, carries the scragging carrying out balance.
Background technology
High-speed wind tunnel balance will carry out scragging, generally under the Mach number M that impact is large, carry out startup and cut-off testing, observe the jitter conditions of balance output signal back to zero and balance, the rigidity of inspection balance when withstanding shocks load and connection, and test the sticking Quality of strainometer and the connection reliability of metering circuit.In addition, before each model carries out wind tunnel test, after balance, model, pole have been equipped with, all need the mechanical connection checking balance under wind tunnel test condition, the temperature effect of assay balance, the reliability of the repeatability that inspection model is tested and balance work and precision.
Balance scragging is originally arranged on the support of wind-tunnel by balance, model, a lever system, completes above-mentioned content of the test in test chamber, and each test needs independent train number to complete, and affect wind tunnel test efficiency, financial cost is higher.Now utilize wind-tunnel existing structure, this device is loaded in the lower wall panels of ultra-expanded section, while other models enter school wind tunnel test, the scragging of balance can have been carried.
Summary of the invention
The utility model relates to a kind of balance scragging device, mainly this device is installed on wind-tunnel supersonic speed diffuser, while wind-tunnel carries out normal assays, can utilize the air-flow in ultra-expanded section, carries the scragging carrying out balance.Research and production efficiency can be improved, reduce financial cost.
The device utilizing wind-tunnel tail gas to carry out balance scragging of the present utility model comprises test module, supporting mechanism and joint, described supporting mechanism is installed on wind-tunnel ultra-expanded section, and described test module is removably installed on described supporting mechanism by described joint.
Preferred described supporting mechanism comprises riser and base plate, both are welded as a whole, described base plate is mounted by means of bolts on wind-tunnel ultra-expanded section, when testing, the described joint being provided with test module is coordinated by post and key is located and is plugged on described riser, and carries out screwed tight at the tail end of described joint by tail bone and fix.
Preferred described test module comprises model, the gentle pole system in sky, and described model is installed on a described lever system via balance, and described lever system is fixed on described joint.
Preferred sky horizontal line draws wind-tunnel by the inner chamber of lever system, described joint and described riser, is connected with TT&C system.
Preferably also comprise inner cone and back shroud, when not testing, described inner cone and described back shroud are installed on described riser.
This device is arranged on wind-tunnel ultra-expanded section, can ensure the carrying out of balance scragging, does not affect again the wind tunnel test carrying out other models in test section.
The utility model has the advantages that: the balance scragging that this device carries out is carried other model wind tunnel tests and carried out, reduce test train number, reduce costs, economic benefit is obvious.
