Takeoff and Landing Analysis (TOLA) Computer Program. Part II. Problem Formulation

Abstract

A well-defined integration of the various aspects of the aircraft takeoff and landing problem is presented in the form of a generalized computer program. Total aircraft system performance is evaluated during the glide slope, flare, landing roll, and takeoff. The flight dynamics of a generalized, rigid body, aerospace vehicle are formulated in six degrees of freedom; a flat, nonrotating Earth is assumed. The independent equations of motion of up to five oleo-type landing gears are also formulated. A control management formulation is developed to automatically adjust control variables to correct errors in the vehicle's dynamic state. Stability in the small is used to maintain stability in the large. The equations of motion are integrated using a generalized variable- step Runge-Kutta technique.
