Conclusion
- Wind tests successfully demonstrated the Superior Performance of CFJ Airfoil
- CFJ Airfoil Significantly Increase Lift , Stall Margin, and Reduce Drag
- Low Penalty to Propulsion System
- No Large LE and TE Required, Can be used for Thin and Thick Airfoil
- Can be Used for Low and High Speed Aifcraft
- No moving Parts Needed
- Two CFJ Airfoil Tested in Wind Tunnel, CFJ0025-065-196, CFJ0025-131-196
- Smaller Injection Size Perform Better for CLmax, Stall Margin, Power Consumed
- Larger Injection Size Reduce More Drag
- Jet Mass Limit and Jet Instability Observed in Experiment
- Super-Circulation Airfoil Possible
CFJ Airfoil promising for
- Aircraft Required Short Take Off/Land Distance (Aircraft Carrier)
- Personal Aircraft to Have Short Take Off/Land Distance, Compact Wingsize, Small Drag
- Long Range Cruiser to Save Fuel
- Combat Aircraft for Fast Acceleration and High Maneuverability
- Quiet Airplane with Low Noise
- Military Aircraft (UAVs) Need Loitering and Supersonic Dash (suggested by G. Hill, NASA LaRC)
- Increase Supersonic Delta Wing Lift at Subsonic Take off and Landing(suggested by G. Hill, NASA LaRC)
