Abstract:

A concept study including experimental testing was made for a projectile proximity fuze backup system. The system incorporates an impact-actuated electrical switch. The switch consists of a circular plate, clamped to the projectile nose, which plastically deforms upon impact to make electrical contact with a nearby surface. For the case studied, which was that of impact into water at an angle of 90 degrees, operating times were found to be in the range of 30 to 50 microseconds. Author
