Project GoalProject Goal

Analyze, design and build an aerodynamic structure which will improve performance by implementation of plasma actuators with optimum aerodynamic conditions along with corresponding efficiency regimes.

Objectives

• To improve critical angle of attack by >20%• Augment Lift vs. Drag ratio by > 15%• Increase Fuel efficiency by 0.5%• Optimize weight vs. takeoff and landing

distance ratio• Determine cost-effectiveness of this system

Design

Airfoil with plasma actuators in place. 1.07 mm trip wire located at the leading edge (not visible).

• Picture 1: NACA 0015 at an AOA of 12°, plasma actuators off – Flow separation/Near Critical AOA

• Picture 2: NACA 0015 at an AOA of 12°, electrode voltage V = 3.6 kV @ 4.2 kHz– Flow separation is delayed, causing significant

reductions in drag

1% reduced drag Boeing 727 = 20,000 gallons of fuel per year = OVER $100,000.00 savings/airplane

Updated in MS project

2 – DUGO DF102-P01 Flyback Transformer

Current Progress

Implementation of microprocessor based control of plasma panels:

(ex: 16 bit PIC Microcontroller)

• frequency • # and location of panels operating• Communication between HV systems• One test model with several scenarios

Up to 30K Volts on each Fyyback operating independent systems

FREQUENCY

Optimal : 5Khz (literature)

Our Future Tests: 2,4,5,6 Khz

Cannot be lower than 1Khz = Residual Current

VOLTAGE

Optimal :30kV

Our Performed Tests: 1,3,4,5,10kV 30 kV and other test dependent on equipment availability

Cannot be lower than 1Khz : Residual Current = periodicity loss

TEMPERATURE

Literature experiments:

High Thermal 107K

Low Thermal 2*104K

non Thermal (surfaces) = 300K

Currently we are calculating our own
