Abstract

Aeroelastic systems are complex and aeroelastic design optimization demands accountability for every variable, every metric, and every constraint. Achieving the best aeroelastic design requires the complexity to be accurately contained. Simple geometric models are scalable in complexity. For instance, intrinsic beam theory is scalable to high fidelity solid finite elements.

Examples of aeroelastic system design research of interest to the U.S. Air Force are Flapping Micro Air Vehicles (MAV), High-Altitude Long-Endurance (HALE) vehicles and Long Range Supersonic vehicles. A competitive design of any of these systems must involve an optimized mix of non-linear structural and non-linear aerodynamic analysis.

The joined-wing SensorCraft variant is a transonic high-flyer with geometric non-linear structural mechanics. The joined-wing has provided an opportunity to develop aeroelastic design optimization with new and unexplored physics. The model development starts with simple geometric forms. Dr Blair will introduce SCOOT, the most practical approach in developing machine accurate geometric sensitivities.

An informal coffee & cookie reception will be held prior to the lecture at 2:30 p.m. in the AAE/ARMS undergraduate lounge (directly in front of ARMS 3rd floor elevators).
