摘要： An end-burning grain of a solid gas-generating composition which may be a propellant for use in rocket motors, in which an elongate metal heat conductor is embedded to increase mass burning rate by the effect of heat transferred from the hot combustion gas to the unburned gas-generating composition through the heat conductor. The improvement resides in that the heat conductor is constituted of a plurality of relatively thin wires which are loosely twisted together. This heat conductor can produce greater extent of increase in the burning rate and has a mechanical strength sufficient for embedding in a practical grain.

摘要： The burning rate of a composite solid propellant comprising ammonium perchlorate and a fuel binder such as polysulfide, polyurethane or polybutadiene can remarkably be increased by the addition of a small amount of FeOOH. Considering the mechanical properties of the propellant, the maximum amount of FeOOH is preferably limited to 7 Wt % of the toatal of the fuel binder and ammonium perchlorate. It is possible to jointly use FeOOH and Fe.sub.2 O.sub.3 on condition that the weight ratio of FeOOH to Fe.sub.2 O.sub.3 is at least 10:90 and that the total weight of FeOOH and Fe.sub.2 O.sub.3 is in the range from 0.9 to 7% of the total weight of the fuel binder and ammonium perchlorate.

摘要： A solid material such as an inorganic carbonate, a salt of a strong inorganic acid and a weak base, or a weak inorganic acid cools gas passing therethrough generated from an azide of an alkali or alkaline earth metal. Toxic, molten particles resulting from decomposition of the azide are trapped and reduced to harmless salts by the solid material.

摘要： The present invention is a binder for a polydiene composite propellant comprising a small amount of binder and has as its object the production of the binder, which can provide stable physical properties between production lots and has a long pot life, and consists mainly of a polymer which has a predetermined molecular weight between crosslinks and which is obtained by reacting a combination of a polydiene glycol having a hydroxyl group number of 1.8-2.1 and a number average molecular weight of 1,000-5,000, a trifunctional crosslinking agent, a diisocyanate and a bifunctional chain extender. When a diene polymer having a functional group number of not more than 1 is additionally added to the above described combination, the elongation of the binder is improved and the use of a plasticizer can be reduced or eliminated.
