THROWN BODY SPEED MEASUREMENT DEVICE Russian patent published in 2009 - IPC G01P3/66 

FIELD: instrument engineering.

SUBSTANCE: invention refers to indicators responding to thrown body passing, for example a bullet, a shell, etc. Device consists of electric contacts closing an electric circuit, which are installed on flexible plates and on which there borne are flexible blades installed at the interfaces of base to apex and interacting with flexible plates of contacts and closing them when the thrown body influences them. Electric contacts are connected with OR element the output whereof is connected with shift register input. The first, the third and the fifth shift register outputs are connected with inputs of three AND elements the second inputs of which are connected with impulse generator output, and outputs - with counters' inputs.

EFFECT: improving informativity of the device owing to measurement both of thrown body speed and air and ground wave velocity.
