The Aerodynamic Design of the Goldenrod - To Increase Stability, Traction, and Speed 660390
A major consideration for world land speed record automobiles is the influence of aerodynamic design on traction, stability, and speed. The features of the successful Goldenrod are described through preliminary design, wind tunnel testing, modifications, performance calculations, and vehicle tests on the Bonneville Salt Flats. These features include lowest minimum drag coefficient (0.1165); download (negative lift) from the shape of the basic body alone; and high-speed stability without the addition of horizontal or vertical fins, spoilers, or weight (ballast).
Design requirements were achieved by the model in wind tunnel tests and the car performed as predicted by these tests, setting a new world record in third gear. The Goldenrod appears to have sufficient potential to also challenge the world speed record for piston engined aircraft.
