The phenomenon of jamming occurs in the inlet sliding slot of a wind tunnel flexible nozzle in the process of forming and zero returning. Aiming at the shortcomings of the existing linkage control method, a single node servo control scheme is proposed in the linkage control method to solve this problem. Two solenoid reversing valves were installed in the node branch and the electromagnet action sequence table was compiled according to different working conditions. Thus the aim of single node follow-up was achieved in linkage control, with two solenoid reversing valves working from the table to solve the jamming problem. Results show that the linkage control improvement method can efficiently solve the jam problem, and this method can provide reference for the optimal design of wind tunnel flexible nozzle in linkage control.
