Minimum Fuel Horizontal Flightpaths In The Terminal Area

three-dimensional formulations. The various problems differ in the final conditions imposed. From the analysis in each problem, the optimal aerodynamic and thrust controls are obtained and the piloting technique to achieve the minimum time is explained.

For determination of the elastic constants of airplane tires which are required for the numerical calculations of the shimmy properties of nose and tail wheels, deformation measurements were carried out on four different tires. For this purpose, the tires were loaded in each case with a normal load and then with a lateral force, a tangential force, and a moment. Moreover, the weight and the mass moment of inertia about a vertical axis were determined for the various tires.
