RANGE EXTENSION FORM RAMJET PROPELLED SHELL

摘要

The present invention relates to a ramjet propelled shell for extending a range which has a ramjet engine of high specific thrust loaded therein and maximizes a high explosive loading amount to improve a firepower support effect. The ramjet propelled shell for extending a range comprises a ramjet engine (20) which sucks air to compress the air, and then combusts solid fuel (22) to spray generated combustion gas through a nozzle (24) on a tail thereof. The solid fuel (22) comprises: first solid fuel (22a) of an annular shape attached to an inner wall of an outer surface (11) of a cylindrical shell; and second solid fuel (22b) of an annular shape which is attached to a center structure of the shell (10), and has an outer diameter smaller than the inner diameter of the first solid fuel (22a). The first solid fuel (22a) and the second solid fuel (22b) are arranged in a dual annular structure.
