The Navy and Marine Corps rely on fixed-wing, rotary-wing, and vertical and short take-off and landing (V/STOL) aircraft to perform a wide variety of missions, such as strike and close air support, air and fleet defense, logistics, expeditionary operations, antisubmarine and anti-mine warfare, and search and rescue. The unique requirements to operate from ships at night, in bad weather, and at high sea states lead to a number of science and technology challenges requiring unique aerodynamic and design attributes.
Research Concentration Areas
Shipboard aircraft are launched and recovered in very confined spaces, and require very agile aerodynamic control to counter wind gusts, ship motions and wakes. Fixed-wing vehicles also require high lift for reduced stall speeds. Overall, naval aircraft require unique design features to support safe operations in densely packed spaces. The Marine Corps depends on fast, agile air vehicles to execute its Ship-to-Objective Maneuver and distributed operations. Achieving all of these requirements while maintaining the ability for long-range force projection calls for advanced aerodynamics and air vehicle designs. This program is soliciting white papers and proposals to conduct basic and applied research addressing unique naval challenges.
