Abstract
The utility model discloses a spray pipe for aerospace wind tunnel test equipment, which comprises a cylinder body, a reinforcing ring arranged on the external surface of the cylinder body, and the inner surface of the cylinder body is shaped like a parabola. By adopting the technical scheme, the spray pipes are connected sequentially, so the construction is convenient and the use reliability is ensured, and the disadvantages of air pores, slag inclusion and cracks of steel castings are eliminated. The parabola-shaped inner hole of the spray pipe ensures the high-speed parallel wind.
Description
Technical field
The utility model relates to a kind of Aero-Space wind tunnel test equipment jet pipe.
Background technology
Wind-tunnel is a basic equipment that carries out the aerodynamics experiment.Most of aerodynamic force experiment is up to now all finished in wind-tunnel.Because the complicacy of gas flow phenomenon and object (aircraft) geometric shape, many problems in aerodynamic studies and the aircraft pneumatic design all can not rely on theory or numerical simulation to solve merely, and must be by a large amount of experiments, find out its rule or data are provided, and combine research with theoretical the analysis, so just can deal with problems, because wind-tunnel is the basic equipment that carries out the aerodynamic force experiment, so the development of aeronautical technology is just directly relevant with the wind-tunnel development.Before any one aircraft formally designs, finalizes the design, all must be through a large amount of blowing experiments.
Spout is a critical component in the wind-tunnel.Existing spout adopts integral solder, occurs shortcomings such as pore, slag inclusion, crackle easily.
The utility model content
Technical problem to be solved in the utility model provides a kind of Aero-Space wind tunnel test equipment jet pipe.Easy construction is used reliably, has eliminated shortcomings such as the pore in the steel-casting, slag inclusion, crackle.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: Aero-Space wind tunnel test equipment is used jet pipe, comprises cylindrical shell, and the appearance of described cylindrical shell is provided with stiffening ring, and the inside surface of described cylindrical shell is a para-curve.
Described cylindrical shell and the welding of described stiffening ring.
Described jet pipe is a steel-casting.
The utility model is owing to adopted technique scheme, and some jet pipes connect successively, and easy construction is used reliably, has eliminated shortcomings such as the pore in the steel-casting, slag inclusion, crackle.The jet pipe endoporus is a para-curve, has guaranteed high speed parallel wind.
Description of drawings
Fig. 1 is the structural representation of the utility model Aero-Space wind tunnel test equipment with jet pipe.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Figure 1 shows that the utility model Aero-Space wind tunnel test equipment uses jet pipe, comprise cylindrical shell 1, the appearance of described cylindrical shell 1 is provided with stiffening ring 2, and the inside surface 11 of described cylindrical shell 1 is a para-curve.Described cylindrical shell 1 and described stiffening ring 2 welding.Described jet pipe 2 is a steel-casting.
The utility model adopts some jet pipes to connect successively, and easy construction is used reliably, has eliminated shortcomings such as the pore in the steel-casting, slag inclusion, crackle.The jet pipe endoporus is a para-curve, has guaranteed high speed parallel wind.
