چکیده

Recent advances in computing power and speed allow designers to simulate thousands, if not millions, of design alternatives more cheaply and quickly than ever before. These advancements provide new opportunities to revolutionize trade space exploration for complex dynamic systems in the aerospace industry, among others. In this paper, we demonstrate our multi-dimensional data visualization software, the Applied Research Laboratory (ARL) Trade Space Visualizer (ATSV), to search for optimal impulsive trajectories in a two-burn plane change spacecraft maneuver. This problem is formulated as a multiobjective optimization problem where it is desirable to explore various competing objectives.

Thrust - Limited Optimal Three - Dimensional Spacecraft Trajectories

Several optimal three-dimensional orbital transfer problems are solved for thrust-limited spacecrafts using collocation and nonlinear programming techniques. The solutions for full nonlinear equations of motion are obtained where the integrals of the free Keplerian motion in three dimensions are utilized for coasting arcs. In order to limit the solution space, interior-point constraints are use...

Near-Minimum Time Optimal Control of Flexible Spacecraft during Slewing Maneuver

The rapid growth of space utilization requires extensive construction, and maintenance of space structures and satellites in orbit. This will, in turn, substantiate application of robotic systems in space. In this paper, a near-minimum-time optimal control law is developed for a rigid space platform with flexible links during an orientating maneuver with large angle of rotation. The time opti...

Aas 16-239 Global Optimization of Low-thrust Interplanetary Trajectories Subject to Operational Constraints

Low-thrust interplanetary space missions are highly complex and there can be many locally optimal solutions. While several techniques exist to search for globally optimal solutions to low-thrust trajectory design problems, they are typically limited to unconstrained trajectories. The operational design community in turn has largely avoided using such techniques and has primarily focused on accu...
