目前处于设计和研制阶段的空间飞行器,其未来的用户要求并期望空间飞行器能提供七至十年的连续工作寿命。为了使空间飞行器稳定系统能达到这样高的可靠性,Charles StarkDraper 试验室(CSDL)同美国无线电公司宇航电子仪器分部签订了合同——设计并研制Block 5D 和泰罗斯-N 卫星的反作用飞轮组件及美国无线电公司承包的卫星通讯系统(SA-TCOM)的动量飞轮组件的机械部分。本文描述了这些飞轮组件的几个革新特点。该设计不但具有高效能的结构(动量与尺寸和重量之比大),而且还采用一个调谐阻尼器来降低传输速率,以免在发射振动条件下损伤轴承。为了取得长寿命,滚珠轴承采用先进的惯性仪表轴承工艺。在这两种飞轮组件上已取得很好的飞行经验,本文对此亦作了介绍。
Spacecraft, currently in the design and development phase, are required by future users and expect spacecraft to provide a continuous working life of seven to ten years. To achieve such high reliability for spacecraft stability systems, the Charles Stark Draper Laboratory (CSDL) has contracted with the U.S. radio company Aerospace Electronics Division to design and develop the reactive flywheel assembly for Block 5D and TIRES-N satellites And the mechanical part of the Momentum flywheel assembly of the U.S.-owned radio company’s satellite communications system (SA-TCOM). This article describes several innovative features of these flywheel assemblies. The design not only has a high-performance structure (momentum and size and weight ratio), but also uses a tuned damper to reduce the transmission rate, so as not to damage the bearing in the emission vibration conditions. In order to achieve long life, ball bearings using advanced inertial instrument bearing technology. Good flight experience has been achieved on both flywheel components, as described in this article.
