Abstract:

A deceleration, orientation and stabilization system for the deployment of the anti-armor mine IRAAM submunition was developed and tested at the Wright-Patterson vertical wind tunnel facility. The system employs a flexible samara airfoil with a tip mass arranged to provide the proper spin rate, descent rate and coning angle. Samara wings of KEVLAR material were fabricated using a flat webbing construction and also a construction consisting of KEVLAR cords enclosed in a nylon envelope. Blades varied in both area and planform aspect ratio. Blade spans ranged from 2.5 to 10.0 inches. Blade widths varied from 2 to 4 inches. All of the IRAAM models used for testing were dimensionally full scale. One model of the nominal configuration was full weight. The other two models were half weight. The tip weight varied up to 5 of the model weight. The test program is outlined. All test procedures and equipment are described. The test results are analyzed and recommendations are made for future developmental studies.
