Overview
The goal of this project is to observe and recreate an airfoil based on its NACA number. Then we will test the model in a simulated condition in order to see if it matches with the known characteristics.
AT-401 Facts
The AT-401B is a 400-gallon workhorse powered by the Pratt & Whitney R-1340 radial engine. It has all the rugged durability, safety features, clean aerodynamics and flying ease for which Air Tractor aircraft are famous – with the economical price of a piston engine plane. The AT-401B delivers unsurpassed value – economically, efficiently and productively.
Airfoil Simulation
The NASA FoilSim determines the lift of the selected airfoil based on the given coordinates and wing geometry. The first number of the chosen NACA number represents the camber and the last two digits represent the thickness of the camber. The flight conditions are set at 60 mph and the altitude is at 0. The data is recorded with the Angle of Attack is set to -20 and the Final Angle of Attack to 20 and the Angle of Attack Step to 5 degrees. Complete Foilsim Excel chart is below the image of the simulator.
