3D Wind Field (3DWF) Model for winds in urban, mountainous and forested terrain
3DWF is being implemented by the Air Force for daily
operational support to the AF/ Army in March 2012 as part of the
Aerostat JUONS effort.
Runs in less than a minute for immediate decisions
Also produces Turbulent Kinetic Energy (TKE) 3D profiles to
warn of shear conditions.
The follow on Atmospheric Boundary Layer Environment (ABLE)
Model will be a full physics forecast model for urban and
mountainous terrain

Corps funded deployment
$4.5M ARL BED SBIR Program in bio-inspired environmental awareness for autonomous systems
Bio-inspired Environmental Awareness
Key Deliverables in FY12:
• 20 MK-2 InstantEye developmental test systems for early deployment
evaluation
• 100 MK-3 systems for deployment using adaptive gust-rejection
techniques developed under this SBIR program
This program currently has active:
• Three Phase I SBIR
• Two Phase II SBIR
• One Phase III deployment SBIR
• Proposals for follow-on FY13 Phase I SBIR
Wind turbulence both inside and outside buildings significantly impacts Micro and
Nano Air Vehicle (MAV/NAV) autonomous hover and navigation through windows and
small openings.
Based on insect and bird awareness sensors and autonomic processing a system is
developed that has total awareness of its own mechanical state, can cope with minor
damage and avoid collisions autonomously, freeing up the operator for attention to
mission.
Future Nano Air Vehicles
will use more responsive adaptive flapping wing controls
