Key Details
Official Description
The Department of Navy (DON) seeks innovative solid-fuel detonation-based propulsion solutions that can deliver superior performance and operational flexibility. The RDE is a promising candidate to replace current constant-pressure combustion systems, due to its high-thermal efficiency, wide-operating Mach range, short combustion time, and small volume. However, to fully realize the benefits of an RDE for naval applications, particularly in the context of ramjet operation, the ability to operate...
