The rapidly fabrication technique for wind-tunnel models of flight vehicle

Based on rapid prototyping, the paper puts forward a rapidly fabrication technique for wind-tunnel models of flight vehicles. The rapidly fabrication technique of integral tap-passage pressure models was developed, deriving from the study of dimensional compensation, taps and passages design and passage configuration design. Focusing on the design and fabrication of structurally similar aeroelastic models, a new method is presented in the paper and validated by modal test. The authors developed a fabrication technique for the fabrication of wind-tunnel models made of metal-resin composite, through the combination of rapid prototyping and electrochemical deposition. The time and cost advantages of the new technique is discussed, too. In summary, overcoming the limitation of traditional fabrication techniques, the rapidly fabrication technique provides a basis of the development of new test techniques.
