METHOD FOR DETERMINATION OF CO-ORDINATES OF TEST OBJECT AT THE INSTANT OF ITS BLASTING Russian patent published in 2006 - IPC F41J5/00 

FIELD: test and measuring equipment, in particular, methods for determination of space co-ordinates of an explosion caused by blasting of the test object.

SUBSTANCE: the method consists in detection of an air shock wave accompanying the blasting of the test object by transducers. The air shock wave is registered by the air shock wave transducers at least in three points of measurement having a survey referencing to the system of space co-ordinated of test area. Besides, at least one light detector and equipment registering the parameters of the undisturbed air medium are installed on the test area. The instant of blasting of the test object is registered by the signal of the light detector, and the moments when the shock wave reaches each test area - by the signals of the air shock wave transducers. On the basis of the obtained data, the distances from the point of blasting to each test area are calculated with due account made for the parameters of the undisturbed air medium. The co-ordinates of actuation of the test object are determined according to the known co-ordinates of the test area and the distances from the blasting point to each test area.

EFFECT: obtained space co-ordinates of the blast, expanded solid angle of determination of co-ordinates to 4π, enhanced precision of determination of co-ordinates.
