Multi-Jack Single-Drive Semi-Flexible Nozzle Mechanism Design and Simulation

Abstract:

In order to reduce the cost of wind tunnel construction, simplify the requirement of control, and increase the security in the operation of nozzle, the multi-jack single-drive semi-flexible nozzle is designed. Based on the planar linkage design theory, the movement of multi-jack semi-flexible nozzle with single drive organ was achieved by using the software of MATLAB. Furthermore, the rigid-flexible coupling kinematics simulation of multi-jack single-drive semi-flexible nozzle is done to testify the rationality of the mechanism design by using the software of ADAMS and PATRAN/NASTRAN. The comparisons of four Mach numbers show that the simulation surfaces have good agreements with the aerodynamics surfaces.
