AUTOMATED INSTALLATION FOR DETERMINATION OF ENERGY-BALLISTIC CHARACTERISTICS OF LIQUID HYDROCARBON COMBUSTIBLES Russian patent published in 2020 - IPC G01N33/22 

FIELD: test technology.

SUBSTANCE: invention relates to testing materials, particularly liquid hydrocarbon fuels for investigating the applicability of liquid hydrocarbon fuels with required characteristics under given conditions. Proposed plant comprises heated working chamber configured to oscillate in the form of cylinder case open at one end, on open end of which there is a membrane or plug, which can replace fuel into working chamber, in which at a fixed distance from each other on the side of the open end pressure sensors are installed, and a fuel-air mixture ignition (blasting) device. Besides, it additionally comprises a unit for continuous supply of hydrocarbon fuel into the working chamber supply channel, a fuel temperature sensor in the fuel injection zone, a flash fixation sensor in the fuel-air mixture firing (blasting) zone, unit for fixation of horizontal, longitudinal and vertical deviations of housing of working chamber at the moment of membrane rupture, unit for creation of rarefaction in housing of working chamber and unit of control of sequence of operations. Pressure control sensors are connected to control unit inputs, fuel temperature sensor in fuel injection zone, unit for fixing horizontal, longitudinal and vertical deviations of working chamber housing, flash fixation sensor, and outputs of this unit are connected to actuators of housing chamber heater, means of ignition (blasting) of fuel-air mixture, unit for supply to working chamber of hydrocarbon fuel and unit of vacuum generation in housing of working chamber.

EFFECT: expansion of the list of determined parameters is achieved with simultaneous increase of accuracy and efficiency of measurement.
