2. Project Goal Design and build an aerodynamic structure which will improve aircraft performance by implementing plasma actuators and their corresponding efficiency regimes 2 1% reduced drag Boeing 727 = 20,000 gallons of fuel per year = OVER $100,000.00 savings/airplane [Ref. 2]

3. Objectives Improve critical angle of attack by >20% Augment Lift vs. Drag ratio by > 15% Increase Fuel efficiency by 0.5% Quantify system feasibility and effectiveness 3

4. Accomplishments Obtained flow physic’s understanding Designed preliminary actuator set-up Constructed experimental flat plate 4

5. Current Date 5

6. Electronics Backup Circuit Previous proved hard to build Varying Frequency not needed for proof of concept Lack of Results Dependence on Larry Buist

7. 7 Simple Circuit Inexpensive Parts Easy to modify and operate Depend on Larry to build Circuit diagram

8. Changes and future work Overall electric system had to be simplified: Discard variable frequency Build variable high voltage power supply Steady frequency due to circuit constraints Work in progress: Determine a working frequency to be used Acquire high voltage wires Work out wind tunnel electric set-up

9. Future Experiments Test Proof of Concept Achieve Drag Reduction Obtain Relevant Data Develop System Regime Voltage Effects Free-Stream Velocity Effects Frequency Effects 9

10. Thermal Analysis Goal Ensure actuators do not burn/melt Objectives Develop heat model Quantify temperatures and heat transfer rates Determine if temperature values and heat transfer rates are allowable 10

11. Thermal Analysis 11 Approach Analyze entire model Make reasonable assumptions of heat transfer (Assume 1-D) Divide actuator accordingly Reintegrate results into model and repeat approach to optimize model
