Abstract: A modular constructed, standardized test device for simulating a spin stabilized projectile which is fired from a barrel having rifling grooves, comprised of the bolted together, keyed to transfer spin, modular components of replaceable rotating band, replaceable front end and back end, and filler sections for further simulation of other components. The front end has an interior recessed area which allows for a selective integration of a threaded fuze or an aerodynamic, electronic, or other structure and the rear end has a crimp groove for selective attachment of a cartridge case, and aerodynamic or other structure to mimic the rear geometry of a projectile for testing purposes.

Abstract: A projectile with a payload protection mechanism protects, prior to and during firing, a fragile payload, where the payload must be positioned forward in the nose of the projectile, within a frangible ogive which provides little protection to rough handling, at time of downrange function. The payload protection mechanism allows the payload to move axially within the projectile, and initially slid rearward in the more robust metal body of the projectile. The payload is retained within the body by a locking and release mechanism, until the launching of the projectile triggers (by environmental forces such as setback or spin) the release of a locking and release mechanism. Unlocking the mechanism allows the payload to slide forward within the projectile into the ogive so the payload can function as required.
