Abstract: The invention provides a momentum wheel energy storage device for a spacecraft or satellite. The device has six wheels whose axes of rotation are parallel to edges of a tetrahedron. It thus provides redundancy which makes it possible simultaneously to store energy and to generate an arbitrary net angular momentum, even in the event of one of the wheels failing. The failure of one wheel can be accommodated without degrading operation, with energy storage being optimal regardless of the angular momentum to be generated. The failure of two wheels can be accommodated but operation may then be in degraded mode. The invention makes it possible to limit the number of momentum wheels used in a device that can accommodate failures.
Abstract translation: 本发明提供了一种用于航天器或卫星的动量轮能量存储装置。 该装置具有六个轮,其旋转轴线平行于四面体的边缘。 因此,它提供冗余,这使得可以同时存储能量并产生任意的净角动量,即使在其中一个车轮故障的情况下也是如此。 可以容纳一个车轮的故障,而不会降低操作,而不管所产生的角动量如何,储能都是最佳的。 可以容纳两个轮子的故障,但是操作可能处于退化模式。 本发明使得可以限制可以适应故障的装置中使用的动量轮的数量。
