Continuous Sustainable Power Supply: Benthic Microbial Fuel Cell

NRL has developed the benthic microbial fuel cell (BMFC) as a persistent power supply for marine-deployed applications. The BMFC operates on the bottom of marine environments where it oxidizes organic matter residing in sediment with oxygen in overlying water. The NRL BMFC is a maintenance free, non-depleting power supply suitable for a wide range of sensors presently powered by batteries.

Stop-Rotor Rotary Wing Aircraft

NRL has developed a patented system and method of transitioning an aircraft between helicopter and fixed wing flight modes. The stop rotor aircraft is capable of both a helicopter mode vertical takeoff and landing (VTOL) and efficient high speed fixed wing flight by flipping the left wing/rotor blade 180 degrees between flight modes. Conversion between flight modes will take about 1-2 seconds and simulations indicate altitude deviations of less than 50 feet.
