“…The immunity of fibre-optic sensors to electromagnetic interference makes them strong candidates for application to the measurement of strain in the barrels of the new generation of electrical guns based upon electromagnetic, electro-thermal and electro-chemical propulsion [1].…”

Fibre Bragg grating (FBG) sensors have been used to monitor the axial and radial strain induced in a 30 mm calibre gun barrel by the passage of a projectile with a muzzle velocity of >1 km s −1 . The performance of the sensors is compared with that of conventional resistive foil strain gauges. The FBG sensors were used to monitor transient strain signatures of duration <100 µs and magnitude up to 10 000 µm m −1 .

The UK is undertaking research into both electromagnetic (EM) and electrothermal-chemical (ETC) propulsion for future weapon systems. In the EM field, efforts have been concentrated in the railgun armature area. Recent work has tried to reduce the parasitic mass of base-push solid armatures, since this leads directly to lower launch energies and greater overall system efficiency. The aim is to understand the many property requirements needed to allow velocities over 2000 ms-' with full mass payloads.
