Ramjet Solid Fuel with Ignition Support for Gun-Propelled Ramjet Shell

摘要

In order to extend the range of 105 mm, 155 mm, 8 inch, or 3 inch, 5 inch hammer shells that are launched to support firepower, The present invention relates to a ramjet fuel which is applied to a range-extended gun mounted with a ramjet engine, which allows a ramjet engine to operate quickly by applying an ignition auxiliary means to the fuel, 1. A ramjet solid fuel which is applied to a range extension gun mounted with a ramjet engine so as to extend the range of the cannon and is disposed between the intake port of the ramjet engine and the injection nozzle, comprising: a fuel body 10 of annular solid; An ignition auxiliary material (20) applied to the fuel body (10) to ignite the fuel body, the fuel body (10) comprising 40 to 90 wt% of HTPB fuel; 5-15 wt% AP oxidizer; 5 to 15 wt% of first metal particles made of aluminum (Al) or magnesium (Mg), and at least one metal selected from the group consisting of boron (B), boron carbide (B ₄ C), zirconium (Zr), and zirconium carbide 0 to 30 wt% of the second metal particles; And inevitable impurities.
