Description
Technical field
The present invention relates to aviation air force wind-tunnel technique field is belonged to, it is applied to wind-tunnel the present invention relates to one kind and tries
The model guard system tested.
Background technology
The wind tunnel technique method widely used as aerodynamic studies, it is the development in the fields such as Aeronautics and Astronautics
Necessary guarantee is provided.Supersonic speed tests the important step as wind tunnel test, during supersonic speed experiment, normal shock wave or one
Serial oblique shock wave inswept test section rapidly, it is subjected to significant forces the model in test section and (is mainly manifested in the method for model
To), it is referred to as " startup load ".With the appearance for starting load, there is strong vibration in model.To model, balance, pole design
Bring problems, be generally aided with certain safety coefficient according to the maximum for the startup load estimated during one side Intensity Design
Come ensure the equipment such as model, balance, pole wind-tunnel start cut-off during security, on the other hand according to this situation design or
Its range of the balance of selection often exceeds several times of model steady state loading, or even more than ten times, and this causes to be difficult to obtain satisfactorily
Aerodynamic test data.Therefore must take steps to, which reduces wind-tunnel, starts/cut-offs load.
In summary, there is an urgent need to develop a kind of model protection mechanism, for protecting wind tunnel test starting/cut-offfing process
Impact to model, ensure the accuracy of wind tunnel test data, improve test efficiency and reduce experimentation cost.
The content of the invention
The present invention is directed to the deficiency in existing wind-tunnel technique, there is provided a kind of model suitable for high-speed wind tunnel protects system
System, it can start in wind-tunnel and shutdown phase protects the safety of model in wind tunnel and balance well, while improve experiment number
According to accuracy.
The technical solution adopted in the present invention is：A kind of model guard system suitable for high-speed wind tunnel, including two sets anti-
Protect mechanism, described two sets protection mechanism is upper and lower is symmetrically mounted on outside test chamber, often cover described in protection mechanism include
It is electric cylinder, servomotor, sliding-rail sliding, slide rail mounting seat, slide rail block, model protection pole, model proof rubber head, electronic
Cylinder u shaped connector, inductance type alignment system, target patch and mounting bracket, electric cylinder and slide rail mounting seat are separately fixed at test section
On the floor of outside, described electric cylinder is connected with servomotor, and sliding-rail sliding is arranged in slide rail mounting seat, the installation of slide rail block
In one end of slide rail mounting seat, model protection pole afterbody is connected with sliding-rail sliding, and model protection branch club head protects with model
Rubber end is connected, and head of the electric cylinder u shaped connector respectively with electric cylinder and model protection pole is connected, and inductance type alignment system is led to
Cross mounting bracket to be fixed in slide rail mounting seat, target patch is fixed on model protection pole, and it is played with electric cylinder motion
Position-limiting action, ensure that electric cylinder moves in stroke；Model protection pole can be moved to inside test section, so that upper and lower
The model proof rubber head of protection mechanism contacts with model, clamps model, ensures the safety of the model when experiment starts and cut-off.
The present invention is compact-sized, and installation operation is convenient, can effectively solve model and pacify when wind tunnel test starts and cut-offs
The problem of complete.It can be very good to ensure the safety of model and balance during wind tunnel test, improve the accuracy of wind tunnel test data, machine
Structure is arranged on the outside of test chamber, and wind-tunnel starts and only had when cut-offfing model protection pole and its head rubber head stretches into experiment
Intersegmental part protects the safety of model, treats that steady air current back stay is withdrawn with Rubber end, is integrated with lower wall panels on test section, nothing
Structure jump.
