PULSE, SPECIAL AND SLIP MODES IN PROBLEMS OF FLIGHT DYNAMICS (IMPULSNYE, OSOBYE I SKOLZYASHCHIE REZHIMY V ZADACHAKH DINAMIKI POLETA),
Abstract
The theory of pulsed, particular, and sliding modes of operation in optimal systems is applied to the study of the following flight dynamics problems: (1) optimization of trajectories of flight vehicles when the angle of attack and the direction of the thrust vector is controlled; (2) optimization of vertical take-off trajectories of an airplane; (3) controlling the thrust of a spacecraft during flight in a central field; (4) the problem of the maximum flight range of an airplane with a simultaneous optimization of the wing area. Under certain simplifying assumptions applied to the flight conditions, the equations of motion are written for all cases, the corresponding variational problems are formulated, and equations for determining extremals are derived. Analyses of pulsed, particular, and sliding modes of operation in the above-defined optimal were made which made it possible in many cases to simplify the solution of these problems. (Author)
