Pressure sensing method and apparatus for gun-launched projectile

A method of determining fluid pressure on a gun-launched projectile relies on deformation of a thin layer of a metallic material that comprises the outer layer of a segment of the projectile body. The axial segment of the projectile body that is selected for pressure measurement is altered or replac...

description A method of determining fluid pressure on a gun-launched projectile relies on deformation of a thin layer of a metallic material that comprises the outer layer of a segment of the projectile body. The axial segment of the projectile body that is selected for pressure measurement is altered or replaced with another axial segment. The altered segment has a thin-walled, structural, metallic sleeve that is concentric with an underlying hollow, metallic cylindrical body. The radially outermost surface of the body underlying the sleeve has a plurality of indentations formed thereon. Measurements of the deformations of the thin-walled sleeve into the indentations in the underlying body are correlated with known deformation and pressure data to determine pressure that was applied to the projectile during its ballistic cycle.
