After an exhaustive review of the present predictive technologies in the relevant fields (airframe, propulsion, propagation, aircraft operations, trajectory optimisation), the paper addresses items for further research and development.
An optimum operation temperature trajectory is obtained by a polynomial fitting method.
During joystick operation, the trajectory of the user's forearm is governed by the motion of the controller, which creates horizontal and vertical movement of the forearm.
The results verify that the optimum operation temperature trajectory with various loads can be tracked by proposed control system and the optimal output performance of PEMFC can be achieved.
Understanding diverse performance trajectories of projects is of interest to operations researchers and practitioners.
Along with designing of descent module systems, including systems of braking in the atmosphere, designing of flight operation sequence and trajectories of motion in the atmosphere is performed.
A launch-assisted, horizontal takeoff, reusable Earth-to-orbit (ETO) vehicle is introduced, described, and its concept of operations, a typical trajectory, its performance, mass and cost estimates are presented.
This operation allowed the trajectories of ejected particles to be visible against the dark background, since the pulse occurred during the evening.
His colleague Gene Kranz described him as "the pioneer leader of trajectory operations, who turned his craft from an art practiced by a few into a pure science".
