Title:
MOVABLE NOZZLE OF ROCKET
Document Type and Number:
Japanese Patent JP3666710
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the breakage of a linear actuator when a throwaway ignitor is used by reducing shock load at the throwing time of the ignitor and excessive load due to the oscillation of the nozzle body.
SOLUTION: A nozzle 11 on a rocket tail 1a is swingable around a pitch axis L'p and a yoke axis L'y. A nozzle driving linear actuator 12 is arranged between the rocket tail 1a and the nozzle body 11 in substantially the axial direction L. A buffering mechanism 20 is arranged on the axial center of the linear actuator 12, which is operated to reduce an operating load in the case that a load from the nozzle body 11 to the linear actuator 12 exceeds a maximum operating load.
