PROPELLANT FILLING APPARATUS FOR SOLID PROPULSION ENGINE AND PROPELLANT FILLING METHOD USING SAME

摘要

The present invention relates to a propellant filling apparatus for a solid propulsion engine and a propellant filling method using the same. The apparatus comprises: a lower roller (10) provided with a mounting portion (13) on which a lower end of a combustion tube (60) is mounted; a connection body (30) which has one end fixed to the lower roller (10), has an insertion space into which the combustion tube (60) is inserted, and connects the plurality of combustion tubes (60) by inserting the plurality of combustion tubes (60) into the insertion space; an upper roller (20) which is fixed to the other end of the connection body (30), has a mounting portion (23) on which an upper end of the combustion tube (60) is mounted, and has a through opening (22) formed in the center thereof; and a core member (40) inserted into the combustion tube (60) through the through opening (22) of the upper roller (20) to form a filling space (61) in which propellant (70) is filled in the combustion tube (60). According to the present invention, the plurality of combustion tubes of the solid propulsion engine can be filled with propellant at the same time, thereby improving productivity and efficiency of the filling process of the solid propulsion engine.;COPYRIGHT KIPO 2019
