GYROINSTRUMENT Russian patent published in 1997 - IPC

FIELD: precision instrument engineering, in particular, gyro horizon compasses, vertical gyros and other instruments, applicable in navigation equipment. SUBSTANCE: gyroinstrument uses hollow casing 1 with base 2 closed with cover 10, brackets 5 secured in the casing that carry gyroscopic sensing element unit 9, electronic units 4 placed in the casing and positioned in parallel with two lateral faces of the casing, and heaters 3 made in the form of film heaters 8 secured on radiator 7. The novelty is in the fact that three additional heaters are introduced, casing 1 is made in the form of an octahedral right-angle prism, and cover 10 is an octahedral one as well; heaters 3 are placed between electronic units 4 and brackets 5 along four lateral faces of casing 1 and attached to base 2 in a spaced relation to casing 1, and each heater is furnished with heat exchanger 6 made in the form of a ribbed angle-piece facing gyroscopic sensing element unit 9; heat exchanger 6 is rigidly fastened to film heaters 8. EFFECT: enhanced precision of gyroinstrument within a wide range of ambient temperature variation, and enhanced reliability. 2 dwg
