Abstract

The invention provides a low burning rate and high energy solid propellant, and belongs to the technical field of solid propellants. The solid propellant comprises the following components in percentage by weight: 17.5 to 22.5% of plasticizer, 6 to 7.5% of adhesive, 6.0 to 8.0% of oxidant, 48.0 to 52.0% of energy containing explosive, 14.0 to 16.0% of metal fuel, and 1.0 to 4.0% of functional additive; wherein the plasticizer comprises a plasticizer A and a plasticizer B, the plasticizer A is composed of nitroglycerin (NG) and butanetrioltrinitrate (BTTN), and the plasticizer B is one or two of butyl nitroxyethyl nitramine (Bu-NENA) and trimethylolethanetrinitrate (TMETN). The provided propellant can solve the problem that low burning rate and high energy cannot be achieved at the same time. The propellant has a low burning rate and high energy, and the standard static burning rate can reach 9 mm / s or lower.

Description

technical field

[0001] The invention relates to a high-energy solid propellant formula for requiring high propellant energy and low burning rate, and belongs to the field of solid propellant. Background technique

[0002] High-energy solid propellant is the power source of advanced strategic and tactical missile engines, and its performance directly affects the combat effectiveness and survivability of missile weapons. Due to the high energy, the high-energy solid propellant generally has the characteristics of high basic burning rate, while the long working time of advanced solid rocket motor requires its propellant to have a lower burning rate. In recent years, advanced solid rocket motors require high energy, high loading, and high mass ratio to require high-energy propellants with high elongation and high modulus. 10mm / s technical requirements.

[0003] GAP / CL-20 high-energy solid propellant uses GAP as a binder and contains CL-20 explosives. The standard measured spec...
