Abstract: A side thruster module, comprises: a cavity-type body skin extending in a longitudinal direction; a first thruster arranged in the body skin and extending in a longitudinal direction; and a conversion nozzle arranged in the body skin and extending in a radial direction perpendicular to the longitudinal direction, for converting a direction of a thrust generated from the first thruster in the longitudinal direction into the radial direction. A large number of thrusters can be mounted at the side thruster module thus to generate a high thrust, and the side thruster module can be slim in the radial direction perpendicular to the longitudinal direction.

Abstract: Disclosed is a jet vane thrust vector control (JV-TVC) system. A general system has many problems in design techniques considering actual operation environments, and does not have reliability in component assembly design. The JV-TVC system improves thrust vector control and high angle of attack maneuvering performance of a missile by allowing rotational angles of jet vanes to maximum ±30°, precisely controls the thrust vector of the missile by preventing damages of components for the designated flight time of the missile, and improves precision and reliability in the assembly process by modularization.

Abstract: A method for assembling a rocket propulsion motor including a motor case and a nozzle assembly, wherein the assembling is carried out under vacuum so that air can not be presented between a silicon sealant layer and a first O-ring disposed between the motor case and the nozzle assembly, thereby preventing the generation of air passage and air pocket in a silicon sealant layer coated over the assembled portions of the rocket propulsion motor. The silicon sealant is prepared by mixing a silicon sealant material with a setting agent. The mixing is also carried out under vacuum, so as to prevent the sealant from containing air. For venting air from a space defined the silicon sealant layer and the first O-ring under vacuum, a plurality of spacing bolts are used which serve to space the motor case and the nozzle assembly at a predetermined distance.
