| Abstract: | Based on the scheme and principle of first stage servo control loop in an active launch vehicle type,a method for first stage engine automatic return-to-zero after fixing in launch site is provided.Test results indicate that first stage engine nozzles return to zero position quickly without bias after taking automatic return-to-zero effort.The scheme for automatic return-to-zero is proved to be feasible and effective. |
