Concept Development of a Pneumatically Driven, Fixed Root Circulation Controlled Helicopter

Circulation control technologies have been applied to fixed wing aircraft for approximately four decades. During those early tests an increase in lift coefficient of nearly four times the unaltered airfoil was achieved. Applying these or similar technologies, particularly inducing the coanda effect through blowing slots to rotorcraft blades, can enhance the performance of the helicopter. The increase in lift coefficient of the rotor blade provides more options to the designer, including decreasing the rotor diameter, decreasing the rotor speed, increasing the payload capacity, or a combination of all three. By either reducing the diameter and/or the rotor speed the blade tip speed can be reduced, thus allowing a higher forward flight speed. Retreating blade stall can also be reduced by applying circulation control to the leading edge of the rotor blade.

Design of a Standardized Roll-On, Roll-Off Sensor Pallet System for a C-130 Aircraft

The development of a standardized roll-on, roll-off (RoRo) sensor pallet system for a C-130 aircraft was conceived by the National Guard and the Counter Narco-Terrorism Technology Development Office to assist in counterdrug reconnaissance activities within the United States and surveillance and reconnaissance missions worldwide. West Virginia University was contracted to perform the design and development of this system because of their innovative design ideas. Before development, the design parameters were established by these two DoD agencies, their mission requirements and by the limitations of the C-130 aircraft. These limitations include using Commercial off the Shelf (COTS) and Government off the Shelf (GOTS) items when developing the system that must be universal on all C-130 aircrafts variants B thru H. Further design criteria are by the limitations of the C-130 aircraft and its existing mission requirements.
