Abstract
In this paper, it was studied the optimization of the cost of interplanetary missions with emphasis on reducing fuel consumption. To achieve this goal, a genetic algorithm was implemented to optimize the total impulse of orbital transfer. It was implemented a case of sending a space vehicle from Earth to a another planet using a gravity assist maneuver (swing by), in this paper it was chose sending a spacecraft from Earth to Mars with a close approach to the Venus. The method employed can be used for impulsive interplanetary missions in general, and so the solution found can become an initial solution for numerical methods of optimization of low thrust maneuvers.
Highlights
There are many different methods and algorithms in computer science for optimizing numerous problems, such as deterministic methods and other methods such as evolutionary algorithms and neural networks.A genetic algorithm (GA) is a search technique used in computer science to find approximate solutions to optimization and search problems
They are a particular class of evolutionary algorithms that use techniques inspired by evolutionary biology such as heredity, mutation, natural selection, and recombination
When a spacecraft passes close to a celestial body and uses that body’s gravity to change its orbit, we call it a "pure swing-by maneuver" or "standard swing-by maneuver". This change includes modifying the spacecraft’s velocity, energy, and angular momentum. This is a type of maneuver known in the literature, already used in space missions, whose main objective is fuel optimization, considering that swing-by is equivalent to the application of a thrust with zero fuel consumption
Summary
There are many different methods and algorithms in computer science for optimizing numerous problems, such as deterministic methods and other methods such as evolutionary algorithms and neural networks.A genetic algorithm (GA) is a search technique used in computer science to find approximate solutions to optimization and search problems. When a spacecraft passes close to a celestial body and uses that body’s gravity to change its orbit, we call it a "pure swing-by maneuver" or "standard swing-by maneuver". This change includes modifying the spacecraft’s velocity, energy, and angular momentum. This is a type of maneuver known in the literature, already used in space missions, whose main objective is fuel optimization, considering that swing-by is equivalent to the application of a thrust with zero fuel consumption. Considering impulse in this case as the application of a force of infinite magnitude in an infinitesimal period of time, so we have that the consequence of this is the instantaneous variation of the speed of the vehicle
