Hey Everyone, so I have just started Aerodynamics and having completed a number of exercises I'm being asked to design an airfoil. I'm a bit outta my dept as I've transferred into this course from a diff field.
1. Homework Statement
To design an airfoil, using the knowledge you've acquired in XFLR5, according to these criteria:
-2,000m
-0.8 m chord
-80m/s velocity
-Not too thin
-Operates close to stall
-naca 4/5 digit
-For help look at the Lockheed U2 example
Okay so the information is a bit limited, considering I'm dealing with 2D airfoil, how do I know what is required of a high altitude aircraft? I've searched google for ages but info seems limited and the books are similar.
What type of values am I looking for in regard to the coefficients.
I assume that I attain Mach Number and reynolds numbers using the usual equations and so can unput that into xflr. I've already completed exercises examining the effect of mach, reynolds no.,thickness and camber in regards to four digit naca profiles.
Thanks
