“…There are several sub-types of burn wires including actuated cable, where a polymer cable is pulled in tension across a hot element, actuated element, where the hot metal cutting element is actuated through the cable, and finally static, where the burn wire and cable are aligned closed to each other and held static 53 . Very commonly used materials are nichrome wires wound around severable nylon or vectran cables 53,54 . This method can also be combined with other restraint mechanisms 55 .…”

Because of the miniaturization of small satellites, most of them have deployables to expand effective areas. However, Small Satellites are not only required to miniaturize systems, but often have a reduced budget, timeline, and employ teams with less experience. The goal of this paper is to provide a starting point for those new to deloyables, and working on small satellites, to understand the approaches available for deployable mechanisms and provide design practices which can improve success rates. To do so, this paper develops a framework for small satellite deployable structures, categorizing them into distinct deployment stages. It investigates the approaches that can be utilized for each stage, focusing on the stow, restrain, actuate, and locate stages. This review paper discusses the advantages and disadvantages of each approach, supported by examples provided in the references. It then highlights best practices for deployable mechanisms, and describes key challenges and future directions. By offering a comprehensive analysis of small deployable systems, this paper aims to guide engineers and researchers in implementing successful design practices for small satellite deployable structures.

The paper focuses on the design of the deployment mechanism for a nanosatellite with a fusible element. The main requirements for this mechanism were: relative simplicity of design, reliability, as well as simplification of the ground testing procedure. Using the principle of fixation on fusible elements, Rose’s alloy in particular, we designed a laboratory prototype of the antenna feed deployment mechanism for CubeSats. Furthermore, we developed a technology of flap deployment control by measuring the conductivity of the fusible element. We carried out a set of tests of the created laboratory prototype on a vibration stand and in a thermal vacuum chamber, as well as a series of functional tests. Comparison of the created prototype with the closest commercial analogs showed that a significant gain in the dimensions of the structure was achieved, as well as the number of elements of the mechanism itself was reduced, which positively affect reliability.
