Propulsion Science
Abstract
The introduction of small military platforms such as Unmanned Air Vehicles (UAVs), Unmanned Underwater Vehicles (UUVs), micro/nanosatellites, and robots has placed a new demand on small-scale, high-performance propulsion systems (less than 10 horsepower). Current small military platforms are being powered by scaled-down versions of larger military propulsion systems, which are not optimized for smaller power demands or for significantly different mission requirements. Furthermore, these small platforms have the same limitations as their larger counterparts being dependent on a single energy source (most are fossil fuel based), suboptimal efficiency, large acoustic signature, and reliability problems. The Propulsion Science thrust will develop new small-scale propulsion systems (less than 10 horsepower) with increased fuel efficiency, reduced signature, and capable of running on multiple energy sources that are robust, adaptable, and scalable. Adaptability and scalability will allow for smart propulsion systems than can run on multi-energy sources, adjust their performance based on operational demands, and have the ability to self-diagnose problems before they impact operational readiness. For example, biomimetic propulsion approaches could allow for low-signature, high-efficiency propulsion for both UUVs and UAVs at a reduced size and weight.
