Airfoil Programs

2D/3D Airfoil Models. Precision 2D and 3D airfoil shapes - that is what Pilot3D gives you. These shapes are accurate and smooth enough for direct numerical control.

FREE SPEED PROGRAM File Size: 749KB Instructions: This will unzip two programs into a folder called Speed on C: drive. These files are: msvbvm60.dll speed.exeDouble click on Speed.exe for the program to run. Enter data and click run.The Speed Program will help you determine the maximum speed of an aircraft. You will need to enter the Flat Plate Drag Area, D/q. The table below shows typical values for D/q.

D/q can also be estimated if the wing area is know. Simply multiply the wing area times 0.02 for a very clean, composite aircraft with retracts. Use 0.04 for fixed gear, aluminum airplanes.
