Abstract
Developing the high attack angle mechanism with good dynamic characteristics is among the key technologies for researching the advanced and highly flexible aircraft weapons. The main test device of the high attack angle mechanism is the pitch mechanism. The pitch mechanism with good dynamic and static characteristics is the key to successful wind tunnel tests. According to the design requirements of the high angle of attack in supersonic tunnel, a new structure and a new working principle of the pitch mechanism are put forward based on the study of the oversea and domestic pitch mechanism. And the error analysis of the pitch mechanism is completed by way of total differentiation method. As a result, the machining accuracy of components is determined after comprehensive analysis. According to the structure and characteristics of the new pitch mechanism in supersonic wind tunnel, the static structure strength and stiffness have been analyzed by using ANSYS system, and so does modal analysis. Computation results show that the pitch mechanism has agreed well with the agreements of the supersonic wind tunnel, and it proves that the structure form of the pitch mechanism is reasonable and reliable.
