Novel Control Technologies for Guidance of High-Spin Stabilized Munitions

The objective of this project is to develop a number of novel guidance and control technology concepts for flight trajectory correction of guided spinning munitions in general and high-spin rounds in particular. The proposed efforts include the development of the required major components, including a number of novel pulsed actuation with very narrow actuation pulse and precision timing and quasi-continuous control surface actuation and direct roll angle sensor concepts with better than sub-degree precision, and the corresponding guidance and control algorithms. The proposed actuation devices can provide impulses equivalent to 10 N-sec to 140 N-sec for up to 2 milliseconds or better. The components of the proposed novel guidance and control actuation concepts are low-volume, consume very small amount of electrical energy, provide high dynamic response control action and are suitable for high-spin rounds with 200 Hz or higher spin rates. The design of these novel pulsed actuation devices and sensors allows them to be readily protected against very high firing setback shock loading of over 50 KG and harsh firing environment and provide shelf life of over 20 years while being capable of operating in the require temperature range of 65 to 165 degrees F.
