In Class Problem: Wind-Tunnel Data Analysis Linear interpolation is a technique used to estimate values of a function at unknown points, between the values at known points. If a function is known at points a and c, (eg. and are known) then, ) ( a f ) ( c f [] ) ( ) ( ) ( ) ( a f c f a c a b a f b f + = A wind-tunnel is a test chamber built to generate different win speeds, or Mach numbers (which is the wind speed divided by the speed of sound). Accurate scale models of aircraft can be mounted on force-measuring supports in the test chamber, and then measurements of the forces on the model can be made at many different wind speeds and angles. At the end of an extended wind-tunnel test, many sets of data have been collected and can be used to determine the coefficient of lift, drag, and other aerodynamic

Unformatted text preview: performance characteristics of the new aircraft at its various operating speeds and positions. Data collected from a wind-tunnel test are below: Flight-Path Angle (degrees) Coefficient of Lift-4-0.182-2-0.056 0.097 2 0.238 4 0.421 6 0.479 8 0.654 10 0.792 12 0.924 14 1.035 15 1.076 16 1.103 17 1.12 18 1.121 19 1.121 20 1.099 21 1.059 Write a program that uses this information to determine the coefficient of lift for additional flight-path angles that are between -4 degrees and 21 degrees. Allow the user to enter the data for two points and a flight-path angle between those points. The program should then compute the corresponding coefficient of lift....
