PLANT FOR DETERMINING BURNING RATE OF SOLID PROPELLANT Russian patent published in 2002 - IPC

FIELD: testing facilities. SUBSTANCE: proposed plant for determining burning rate of solid propellant has combustion chamber, solid specimen of rocket propellant, pressure transmitter, cover with mating cone and radiator, with UHF receiving-transmitting transducer butt-jointed at inlet. The following modification is carried out in plant: outlet of radiator is connected with solid propellant specimen holder made in form of cup with inner diameter exceeding diameter of mating cone. Part of space of chamber located opposite to radiator is filled up with asbestos. Combustion chamber is connected with vacuum chamber through pipeline with actuating mechanism to open valve by time relay signal. Invention makes it possible to create high capacity plant for determining burning rate of specimens of any diameter in controlled pressure range, including tests in vacuum. EFFECT: enlarged operating capabilities. 2 cl, 2 dwg
