In recent years, the development of new satellites has accelerated, especially for small satellites like university-class Cubesats, due to low design and manufacturing costs. The preliminary design of these spacecraft requires the utilization of new tools that improve the interrelation among the different subsystems and optimize the design. One of the most suitable approaches is the concurrent design facility, which connects specialists of each subsystem in the same room to facilitate the communication among them. This method provides different preliminary designs for the complete system by an iterative process in a reduced time, taking into account the simultaneity with the designs of the subsystems. One of the main subsystems of a spacecraft is the propulsion system, which plays a key role in the success of a mission by allowing the spacecraft to reach the final destination. Electric propulsion has become an interesting option due to the high value of the specific impulse, which provides the necessary velocity increment with a lower propellant mass compared to the traditional chemical rockets. The purpose of this paper is to present the equations implemented in the propulsion module of the concurrent design facility to obtain optimum designs of ion thrusters, which supposes a novelty compared to the traditional design approach of these systems, where there is no interaction with the design of the rest of subsystems. The objective is to help the designer to select the best options in a fast and easy way and improve the efficiency of the iterative work of the concurrent design facility.

并行设计设施中离子推进器的优化初步设计

近年来,由于设计和制造成本低,新卫星的开发速度加快,尤其是像大学级立方体卫星这样的小卫星。这些航天器的初步设计需要利用新工具来改善不同子系统之间的相互关系并优化设计。最合适的方法之一是并行设计工具,它将同一房间内的每个子系统的专家连接起来,以促进它们之间的交流。该方法通过迭代过程在更短的时间内为整个系统提供不同的初步设计,同时考虑到与子系统设计的同时性。航天器的主要子系统之一是推进系统,通过允许航天器到达最终目的地,它在任务的成功中起着关键作用。由于比冲值高,电推进已成为一个有趣的选择,与传统的化学火箭相比,它以较低的推进剂质量提供必要的速度增量。本文的目的是提出在并行设计设施的推进模块中实现的方程,以获得离子推进器的最佳设计,与这些系统的传统设计方法相比,它具有新颖性,其中没有与设计的交互其余子系统。目标是帮助设计人员以快速简便的方式选择最佳选项,并提高并发设计工具的迭代工作效率。
