Design of a Wing for Formula One Category Airplanes 2019-01-1337
This paper describes the design of an International Formula One (IF1) racing airplane wing. The first step consists on the simulation of the airplane flying on the race track in other to obtain details about the condition in which the wing needs to be design and optimized. The paper describes the details and formulation used to perform this simulation using parametric flight paths and a point model dynamic model. A scheme to analytic obtain the control laws for the simulation using Frenet-Serret frames over the parametric flight path. Two different airplanes, with different power levels, were simulate on a typical IF1 race track in order to determine the range of lift coefficient in which the wing must be designed. Based on this lift coefficient range a set of four new airfoils were designed based on the NLF0414-F airfoil, and their usage over the wing span were determined, using nonlinear lifting line method, in order to assure that during the race the wing will be operating inside the laminar drag bucket. Finally, this paper describes some details of the wing structural design and fabrication, besides some comparisons with predicted performance and actual performance obtained by two pilots during the National Championship Air Races.
