The application of magneto rheological dampers for controlling recoil dynamics is examined, using a recoil demonstrator that includes a 0.50 caliber gun and a MR damper referred to as recoil demonstrator. Upon providing a brief background on MR dampers and fire out of battery dynamics, we will describe the recoil demonstrator, along with some of the test results from the laboratory and field-testing from the MR damper on the recoil demonstrator. The test results indicate that the MR damper is able to effectively control the recoil dynamics, and provide a different force-stroke curve for different amounts of current supplied to the damper. The current to the damper is used to energize the magneto rheological fluid within the damper and provide different amounts of damping force. Based on the recoil control results achieved by the damper, a technique is suggested for using MR dampers for fire out of battery. The technique, which consists of two stages, is described in detail along with the potential role of MR damper in each stage. Finally, our plans for field-testing the suggested fire out of battery method, using the recoil demonstrator and the MR damper, is briefly discussed.
