摘要： Salicylate esters have been found to be suitable blocking agents for polyisocyanates, enabling preparation of hydroxy terminated polybutadiene based polyurethane bound propellant grains having extended pot life. Unblocking occurs readily at normal propellant cure temperatures, allowing normal cure rates.

摘要： Compositions and methods for increasing the storage life of a propellant grain by reducing the rate of decomposition of its nitrate ester components. A nitrate ester stabilizer is placed in a layer adjacent to a nonburning surface of the propellant grain. The stabilizer migrates from the layer into the grain's nonburning surface to provide additional stabilization for the entire grain, especially portions of the grain adjacent to the protected nonburning surface.

摘要： An insensitive high explosive is obtained by using a dicyandiamide (DCDA), ammonium nitrate (AN), guanidine nitrate (GN), ethylene diamine dinitrate (EDDN) eutectic melt binder in combination with ammonium perchlorate (AP) oxidizer, fine RDX (1 .mu.m to 10 .mu.m particle size), and aluminum metal as a fuel. The fine RDX particles improve performance, boosterability, and sensitivity. The inclusion of AP greatly improves air blast by adding oxygen to the reaction and insuring complete combustion of the ingredients. The aluminum extends the pressure pulse. The ratio of materials is formulated to obtain the lowest known processing temperature.

摘要： Process for forming a liner and cast propellant charge in a rocket engine casing without separately precuring the liner, comprising the steps of providing a blocked curable liner composition which is the reaction product of a prepolymer, an isocyanate curing agent, and a blocking agent; applying the liner composition to an internal surface of a rocket casing; preheating the casing and liner assembly to simultaneously prepare the assembly for receiving a propellant, unblock the liner, and precure the liner to a tacky state; casting the propellant change into interfacial contact with the liner; and cocuring the liner and propellant compositions. The blocked, curable liner composition has a very long pot life which is terminated by heating the composition sufficiently to uncouple the blocking agent from the isocyanate curing agent and initiate a rapid cure. The liner composition does not require precuring, as it is unblocked by preheating the liner and rocket casing sufficiently to receive to cast propellant. The blocked liner composition has the following structure. ##STR1##
摘要翻译： 在火箭发动机壳体内形成衬套和铸造推进剂装料的方法，而不单独地预固化衬套，包括提供作为预聚物，异氰酸酯固化剂和封闭剂的反应产物的封闭的可固化衬垫组合物的步骤; 将衬垫组合物施加到火箭套管的内表面; 预热壳体和衬套组件以同时准备用于接收推进剂的组件，解开衬套，并且将衬垫预先固定到发粘状态; 将推进剂变成与衬管的界面接触; 并固化内衬和推进剂组合物。 封闭的可固化衬里组合物具有非常长的适用期，其通过充分加热组合物而终止，从而使封端剂与异氰酸酯固化剂分离并开始快速固化。 衬垫组合物不需要预固化，因为它通过预热衬套和火箭套筒足以接收来铸造推进剂而被阻挡。 封闭的衬垫组合物具有以下结构。 （5）
