论文摘要
Rexus 29上的Daedalus 2 Mission是一种技术演示器，用于基于自动旋转的高海拔降落的替代下降机制。它由两个探针组成，这些探针从约80 km的高度上从声音的火箭弹出，并仅使用带有俯仰控制的被动转子减速至软着陆。这种自主的科学实验对电子子系统提出了巨大挑战，其中包括机械应力，电力系统可靠性，传感器冗余，子系统通信和开发程序。根据Daedalus收集的数据，开发了多种新方法来满足这些要求，例如冗余通信链接，PCB的机械解耦和容忍故障的电源选择。
The Daedalus 2 mission aboard REXUS 29 is a technology demonstrator for an alternative descent mechanism for very high altitude drops based on auto-rotation. It consists of two probes that are ejected from a sounding rocket at an altitude of about 80 km and decelerate to a soft landing using only a passive rotor with pitch control. This type of autonomous, scientific experiment poses great challenges upon the electronics subsystem, which include mechanical stress, power system reliability, sensor redundancy, subsystem communication, and development procedures. Based on the data gathered in Daedalus 1 multiple new approaches were developed to fulfill these requirements, such as redundant communication links, mechanical decoupling of PCBs and fault-tolerant power source selection.
