波兰科学院空间研究中心与Astronika公司一起开发了一种名为Dragon的轨道布置器，用于弹射波兰科学纳米卫星BRITE-PL Heweliusz(图1)。该装置有三个独特的机构，包括欧空局罗塞塔飞行任务MUPUS仪器采用的和按比例调整的锁定和释放机构。本文讨论了部署器的主要设计限制、独特的设计功能，以及通过测试从开发中吸取的经验教训。BRITE星座是一组科学的纳米卫星，其目的是研究我们银河系中最明亮的恒星(亮度大于+3.5等)的光强振荡。这些观测的精度将至少比地面观测的精度高10倍。由奥地利、加拿大和波兰组成的BRITE(光明目标探测器)任务将向太空发射一个由六个纳米卫星组成的星座，每个国家两个。Brite-PL卫星是基于加拿大SFL/UTIAS(空间飞行实验室/多伦多大学航空航天研究所)的通用纳米卫星总线(GNB)。航天器将使用SFL XPOD(实验推出式展开器)作为分离系统。图1.Dragon Orbary Deployer和BRITE-PL Heweliusz航天器(在保险箱中)*波兰科学院空间研究中心，华沙，波兰
The Space Research Centre of the Polish Academy of Sciences (SRC PAS) together with Astronika company have developed an Orbital Deployer called DRAGON for ejection of the Polish scientific nanosatellite BRITE-PL Heweliusz (Fig. 1). The device has three unique mechanisms including an adopted and scaled lock and release mechanism from the ESA Rosetta mission MUPUS instrument. This paper discusses major design restrictions of the deployer, unique design features, and lessons learned from development through testing. Introduction BRITE Constellation is a group of scientific nanosatellites whose purpose is to study oscillations in the light intensity of the most luminous stars (brighter than magnitude +3.5) in our galaxy. The observations will have a precision at least 10 times better than achievable using ground-based observations. The BRITE (BRight Target Explorer) mission formed by Austria, Canada and Poland will send to space a constellation of six nanosatelites, two from each country. BRITE-PL satellite is based on the Generic Nanosatellite Bus (GNB) from the Canadian SFL/UTIAS (Space Flight Laboratory / University of Toronto, Institute for Aerospace Studies). The spacecraft are to use the SFL XPOD (Experimental Push Out Deployer) as a separation system. Figure 1.
