Because the family of countermeasures may require a range of ejection impulses to reduce the pressure stress and shock environment, a variable ejection system is needed to deliver the required impulse based on specific countermeasure properties and launch depth. The current system uses a common fixed output ejection system for all devices to be ejected. The next-generation ejection system will have the capability to automatically select and control the impulse imparted to the ejected device with the impulse being tailored to the weight and desired velocity of the device to be ejected. In the proposed Phase I program, concept feasibility and suitability for optimized countermeasure ejection will be demonstrated through a combination of simulation and experimentation. A simulation capability will be developed that includes the parameters and physical phenomena that are required to properly describe the ejection event. By simulation, the baseline design can be optimized to meet the impulse and countermeasure ejection velocity requirement with a minimum peak acceleration level. Full-scale experimental work will help to validate the simulation capability and demonstrate the critical functions of the ejector concept. Benefits: The proposed program is designed to investigate the feasibility of a programmable, variable ejection system concept for ejecting underwater submarine launched acoustic countermeasures. The specific technologies and concepts to be investigated during the proposed program are of primary interest to military markets; however, variants of the proposed concept are expected to find applications in various commercial markets Several promising commercial applications for the variable impulse gas generator concept are anticipated that include underwater, earth surface, atmospheric and space scenarios. These include but are not restricted to applications involving underwater salvage, underwater oil exploration, rescue operations, terrorist interdiction (Homeland Defense), as well as ejection of material during space operations. To facilitate the commercialization effort, Veritay plans to enlist the services of Marketing Decisions Group, Inc., a company affiliated with the State University of New York at Buffalo and with expertise in the areas of market assessment and development.
