Abstract
The utility model discloses a jet tube assembly of navigation wind tunnel trial equipment, including a throat and several jet tubes connected in sequence, wherein the inner surface of each jet tube is of a parabolic curve shape. According to the utility model, the jet tubes are connected in sequence, construction is convenient and operation is safe, and the jet tube assembly is capable of eliminating air holes, slag blister, cracks and the like in cast steel parts. The inner hole of the jet tube is of a parabolic curve shape, which ensures high speed parallel wind.
Description
Technical field
The utility model relates to a kind of Aero-Space wind tunnel test equipment spout.
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 spout., 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 spout, comprises venturi and the some jet pipes that are connected successively, and the inside surface of described jet pipe is a para-curve.
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 spout.
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 spout, comprise venturi 1 and the some jet pipes 2 that are connected successively, the inside surface 21 of described jet pipe 2 is a para-curve.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.
