FIELD: fire control equipment of aircraft and spacecraft. SUBSTANCE: gear has combustion chamber connected in series with filter of mechanical admixtures and heat exchanger, igniter with electric spiral at one end of holder and tested specimen placed inside combustion chamber. Salient feature of gear lies in positioning of combustion chamber, heat exchanger and inlet branch pipe of sorbing filters uniaxially along longitudinal axis. Recess made in body of combustion chamber houses igniter and the other end of holder is put on wall of recess with the aid of joint. Igniter is fitted with mechanism for its movement into working zone. Holder comes in the form of cover closing recess. EFFECT: increased quality of flux when process of burning of specimens of non-metal materials is examined. 1 cl, 2 dwg
