DEVICE AND METHOD FOR MEASURING ACCELERATION ON AN OPTICAL DISCHARGE WITH LASER IGNITION Russian patent published in 2022 - IPC G01P15/00 

FIELD: instrumentation.

SUBSTANCE: inventions group relates to the field of instrumentation. The device for measuring acceleration on an optical discharge with laser ignition consists of a spherical chamber, transparent to laser radiation, filled with a gas mixture; one or more lasers located outside the spherical chamber, the radiation of which is focused in the center of the spherical chamber, while the entire inner surface of the spherical chamber, free from laser radiation of one or more lasers, has heat flux sensors, while the number of heat flux sensors that fall entirely into the thermal spot of the heat flux of the gas heated from the optical discharge on the inner surface of the spherical chamber must be greater than or equal to three in any of two mutually perpendicular directions.

EFFECT: expansion of the measurement range of accelerations and improvement of performance.
