Abstract
1. Способ определения характеристик срабатывания пиротехнических изделий при тепловом воздействии, включающий тепловое воздействие на корпус пиротехнического изделия с заданным темпом нагрева и определение факта его самопроизвольного срабатывания, отличающийся тем, что тепловое воздействие на пиротехническое изделие производят с заданным постоянным темпом нагрева корпуса до момента его самопроизвольного срабатывания и фиксируют температуру корпуса пиротехнического изделия, при которой произошло самопроизвольное срабатывание, повторяют эту операцию поочередно с другими аналогичными пиротехническими изделиями с заданным шагом по темпу нагрева до получения зависимости температуры самопроизвольного срабатывания от времени нагрева корпуса, по которой определяют время самопроизвольного срабатывания пиротехнического изделия при аварийном спуске штатного изделия, используя расчетный темп нагрева корпуса пиротехнического изделия.2. Устройство для определения характеристик срабатывания пиротехнических изделий при тепловых нагрузках, содержащее нагреватель с рабочей камерой, средство измерения температуры, подключенное к регистратору температуры, отличающееся тем, что в него введены изолирующий кожух, источник питания регулируемой мощности, подключенный к нагревателю, который выполнен в виде теплового излучателя и размещен по внешнему контуру рабочей камеры, при этом рабочая камера выполнена из прозрачного электроизолирующего материала и вместе с нагревателем помещена в изолирующий кожух, а средство измерения температуры установлено на корпусе пиротехнического изделия.1. A method for determining the response characteristics of pyrotechnic products when exposed to heat, including the thermal effect on the body of the pyrotechnic product with a given heating rate and determining the fact of its spontaneous operation, characterized in that the thermal effect on the pyrotechnic product is carried out with a given constant heating rate of the case until its spontaneous actuation and fix the temperature of the body of the pyrotechnic product, at which there was a spontaneous operation, p alternately repeats this operation to other similar pyrotechnic articles at a predetermined pitch in the rate of heating until the temperature dependence of the spontaneous response from the body heating time, using which the time accidental triggering of the pyrotechnic articles at regular emergency descent products using the calculated heat rate izdeliya.2 pyrotechnic housing. A device for determining the response characteristics of pyrotechnic products under thermal loads, comprising a heater with a working chamber, a temperature measuring device connected to a temperature recorder, characterized in that an insulating casing is inserted into it, a regulated power supply connected to a heater, which is made in the form of a thermal the emitter and is placed along the external contour of the working chamber, while the working chamber is made of transparent electrically insulating material and together with the heater placed in an insulating casing, and a means of measuring temperature is installed on the body of the pyrotechnic product.
