AUTONOMOUS MEASUREMENT OF THE INITIAL VELOCITY OF AN OBJECT THAT CAN BE FIRED

摘要

The invention concerns a process for measuring the initial velocity V0 of an object that can be fired such as a shell or projectile that exits a barrel, said measurement being based on measurement of the force exerted on a sensor device (100) configured inside the object that can be fired, characterized in that the force is measured autonomously inside the object by detection of changes in shape of the sensor device (100) during movement of said object inside the barrel prior to its exit. The invention also concerns a device for measuring the initial velocity V0 of an object that can be fired such as a shell or projectile that exits the barrel of a firing device such as an artillery piece, comprising a force-detecting sensor device (100) configured inside the object that can be fired, characterized in that the force-detecting sensor device (100) is configured so as to detect changes in shape of said sensor device (100) during movement of said object inside the barrel prior to its exit, and in that an included signal-processing unit calculates and determines the initial velocity V0 based on the detected changes in shape. The invention also concerns a device and process for measuring the acceleration forces acting on an object that can be fired during movement of said object inside the barrel prior to its exit.

1. A process for measurement of the initial velocity V0 of an object that can be fired that exits a barrel, said measurement being based on measurement of a force exerted on a sensor device configured inside the object that can be fired, wherein said force is measured internally in the object by detection of physical change in shape of the sensor device during movement of said object inside the barrel prior to its exit, wherein the physical change in shape of the sensor device is measured based on the change in resistance in the sensor device.
