the directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. the dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank model. ...

Contemporary research is improving techniques to maneuvers control in the area of spacecraft. In the aspect of further development of investigations, a high-performance strategy of maneuvers control is proposed in the present research to be applicable to deal with a class of the aforementioned spacecrafts. In a word, the main subject behind the research is to realize a high-performance three-di...

In this paper, we study the problem of designing optimal coordinated maneuvers for multiple aircraft conflict resolution. We propose an energy function to select among all the conflict-free maneuvers the optimal one. The introduced cost function incorporates a priority mechanism that favors those maneuvers where aircraft with lower priority assume more responsibility in resolving the predicted ...

In this paper a direct method based on a transcription by Finite Elements in Time has been used to design optimal interplanetary trajectories, exploiting a combination of gravity assist maneuvers and low-thrust propulsion. A multiphase parametric approach has been used to introduce swing-bys among thrust and coast arcs. Gravity maneuvers are at first modeled with a link-conic approximation and ...

The candidate maneuvers may involve not o...

In air traffic management, conflict prevention information refers to the guidance maneuvers, which if taken, ensure that an aircraft’s path is conflict-free. These guidance maneuvers take the form of changes to track angle or ground speed. Conflict prevention information may be assembled into prevention bands that advise the crew on maneuvers that should not be taken. Unlike conflict resolution...

In air traffic management, a pairwise conflict is a predicted loss of separation between two aircraft, referred to as the ownship and the intruder. A conflict prevention bands system computes ranges of maneuvers for the ownship that characterize regions in the airspace that are either conflict-free or “don’t go” zones that the ownwhip has to avoid. Conflict prevention bands are surprisingly dif...

U-turn maneuver is a special taxiing behavior on the ground. This paper studied the behavior and aimed to research the problem of position and attitude during the movement. From the perspective of airport tower control simulation, the calculation methods that the aircraft did U-turn maneuver under the nonholonomic constraints were proposed. According to the real geometrical constraints and kine...
