Cal Poly Flutter Club

Design driver: Conduct aeroelasticity and flutter tests in a small-scale wind tunnel

Project Guidelines

• Design, fabricate, and test a gust generation system
• Produce gust frequencies at up to 20 Hz and 300 ft./sec. tunnel speed
• Design and fabricate scaled model of Lockheed X-56A
• Fly model in wind tunnel using 5DOF gimbal
• Design gust generation system to be removed and reinstalled as needed

Results

• Installed and tested early 2013
• Minimal flow disturbance measured at zero degree deflection of gust vanes
• Sinusoidal gusts up to 20 Hz and 200 ft./sec. verified
• Gust generation system videos (copyright Justin Enrique 2013):
  • Gust generation system in action   
  • Gust generation system sensors and walkthrough
