Project GoalProject 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]
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
AccomplishmentsAccomplishments
• Obtained flow physic’s understanding
• Designed preliminary actuator set-up
• Constructed experimental flat plate

• Simple Circuit• Inexpensive Parts• Easy to modify and operate•Depend on Larry to build
Circuit diagram
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
Future ExperimentsFuture Experiments
• Test Proof of Concept• Achieve Drag Reduction• Obtain Relevant Data
• Develop System Regime• Voltage Effects• Free-Stream Velocity Effects •Frequency Effects

Thermal AnalysisGoal
• 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
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
