Takeoff and Landing Analysis Computer Program (TOLA). Part III. User's Manual,

摘要

TOLA is an acronym for TakeOff and Landing Analysis digital computer program. This part describes the use of the program. The basic program provides six rigid-body degrees of freedom of aerospace vehicle motion over a flat planet and determines the response of the aircraft to control inputs. The dynamics of up to five independent oleo-type struts are included for simulation of symmetrical and nonsymmetrical landings as well as drop tests. A maneuver logic is programmed to provide vehicle guidance in the various phases of the problem;it determines the desired trim and position in the glide slope and provides synthesis and attempted completion of necessary flare dynamics for prescribed touchdown velocity vector. The landing roll includes wheel spinup and braking,thrust reversing,spoiler deployment,and system failure options. The takeoff roll consists of acceleration to takeoff speed,followed by rotation to takeoff angle of attack. (Modified author abstract)
