Abstract

570,211. Explosives; projectiles; cartridges. TAYLOR, J., OWENS, R. D. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 6, 1942, No. 15689. [Classes 9 (i) and 9 (ii)] A gas-escape reaction-propelled device such as a rocket projectile or aeroplane take-off apparatus comprises a. compact smokeless powder charge 5, which is to generate the propulsive gas, in association with one or more oxidizing charges 6, 7, which are so shaped and positioned that substantially the whole of the surface thereof is swept by the stream of propulsive gases before the stream escapes through the venturi nozzle 2 to the atmosphere. The function of the charges 6, 7 is to supply oxygen to the propulsive gases to burn carbon monoxide and hydrogen contained therein. The charges 6, 7, which may be tubular, as shown, or rodlike, and enclosed in a celluloid container, are made by casting a composition which is pourable at 115‹ C. or less and which comprises (a) ammonium nitrate, (b) an alkali metal or ammonium chromate, bichromate or polychromate (the function of which is to enable the decomposition of the ammonium nitrate to take place at a lower temperature than would otherwise be the case), and (c) a solid non-alkaline non-oxidizable substance which promotes fusion of the ammonium nitrate and which may be anhydrous alkali metal nitrates, perchlorates or chlorides, anhydrous alkaline earth metal nitrates or chlorides, lead nitrate, ammonium perchlorate, anhydrous magnesium sulphate or hydrated alkaline earth metal nitrates or chlorides. The smokeless powder charge may comprise nitroglycerine, nitrocellulose and diethyl-diphenyl urea. A blackpowder igniting charge 8 is disposed between the charge 5 and a seal 4 which separates the combustion chamber 1 from a threaded union À 3 adapted to receive the projectile &c. Grids 10, 11, 12 separate the charge from each other and from the venturi nozzle. The nozzle may have a temporary waterproof closure. Specifications 570,075 and 570,210 are referred to.
