PROPOSAL TITLE: Next Generation Design Technology for Micro Rotorcraft

Recent developments have illustrated the tremendous potential of Micro
Rotorcraft (MRCs) for new missions such as remote sensing, surveillance,
and autonomous exploration. To date, little effort has been directed
toward addressing the severe aerodynamic limitations inherent in operating
at low Reynolds number that have greatly constrained MRC performance.
Phase I of this effort saw the development of novel blade configurations
tailored to a range of MRC missions via a combination of advanced
optimization methods for low Re airfoils and application of established
rotor analysis tools. These validated analyses demonstrated the potential
of new configurations to provide double the payload or endurance of current
generation MRCs. Phase II will build on this to yield new, comprehensive
design analysis software to support development of next generation MRC
rotor systems, forming the foundation of a suite of tools enabling
multi-disciplinary optimization of the full range of rotorcraft from MRCs
to full scale vehicles. This will enable a formal design capability for
MRCs, bypassing the prevalent cut-and-try approach. The design analysis
will then be used to perform a complete design of an MRC rotor system for a
free flight vehicle.

The recent rapid expansion of MRC missions in defense applications is being
mirrored by growth in possible civil roles for MRC concepts, including
aerial imaging, inspection, and specialized payload delivery. Important
Phase III goals of this effort would include producing and marketing a
family of rotor systems for next generation MRCs, as well as providing
software for design of autonomous rotorcraft for future missions, including
possible exploration of planetary atmospheres. In addition, through a
collaboration with established industry partners during Phase II, the low
Re design technology to be developed here will be applied both to the
development of improved autonomous helicopters as well as to the design of
high efficiency cooling fans for air treatment applications.
