Abstract

Described herein are multi-part projectiles that include a high-friction coating as part of an interface between parts of the projectile body. The high-friction coating reduces the probability that projectile parts coupled at the interface would rotate relative as the projectile is launched, thus enhancing the reliability and accuracy of the projectile. In one example, a multi-part projectile includes a projectile body having first and back sections coupled by an interface. The front section has a front land and the back section has a back land. The threaded interface restrains the rotation of the projectile body first and back sections. A high-friction coating is disposed on at least one of the lands of one or both the front and back sections. The high-friction coating has a co-efficient of friction greater than the parent metals against each other alone, without the high-friction coating disposed therebetween.

Abstract

Rocket-assisted artillery rounds and methods for firing the same are described herein. In one example, a rocket-assisted artillery round includes a projectile body, rocket fuel disposed in the projectile body, an ignitor positioned to ignite the rocket fuel, and an ignition control system. The ignition control system includes a controller coupled to first and second sensors. The first sensor is configured to detect a first metric. The first metric is indicative of rotation of the projectile body. The second sensor is configured to detect a second metric. The second metric is indicative of setback of the projectile body. The controller is configured to output an activation signal to the ignitor based on the first metric and the second metric.

Abstract

Embodiments of the present disclosure relate to the field of ammunition rounds for training or tactical purposes. In one or more embodiments, the projectile is equipped to transmit an improved visual signature upon impact, including one or both of flash and smoke signatures. In one example, a projectile includes a projectile body, an ogive coupled to the projectile body, and a boat tail having a degree of transparency coupled to the projectile body. The boat tail having a degree of transparency and the projectile body define a cavity within the boat tail having a degree of transparency and the projectile body. A flash producing material is disposed within the cavity.
