摘要:
The gravity control apparatus (1) comprises: a first rotating body (10) that rotates along a first shaft (11a) as a result of being driven by a first driving device; a second rotating body (20) that rotates along a second shaft that is orthogonal to the first shaft (11a) within the region of rotation of the first rotating body (10) as a result of being driven by a second driving device; an accelerometer (40) that is set at any position on the second rotating body (20) and detects acceleration; and a control device (50) that controls driving by the first driving device and the second driving device. The control device (50) controls driving by the first driving device and the second driving device on the basis of acceleration data detected by the accelerometer (40).

L'invention concerne un banc (1) de test d'un senseur stellaire, caractérisé en ce qu'il comprend : - un senseur (2) stellaire comprenant un baffle (3) de protection, - un collimateur (7) monté sur une extrémité du baffle (3) de protection, - un écran (5) apte à afficher une portion défilante du ciel, l'écran (5) étant disposé à distance de focalisation du collimateur (7), de sorte à projeter vers une surface (15) sensible du senseur (2) stellaire une image collimatée de la portion défilante du ciel.
摘要:
Eine Lageranordnung (4) zum Abstützen von Zugkräften, insbesondere zur hängenden Lagerung einer Masse, um in einem Gravitationsfeld deren Schwerelosigkeit zu simulieren, weist ein erstes, zumindest einen Magneten (18) umfassendes Lagerelement (14) und ein zweites, metallenes Lagerelement (16) auf, an das sich das erste Lagerelement magnetisch anzieht. Zumindest eines der Lagerelemente weist in seiner Lagerfläche (20) Gasaustrittsdüsen (22) auf, die von einem Druckgas beaufschlagt sind, so daß ein aus den Gasaustrittsdüsen austretender Gasstrom ein Gaspolster zwischen den aufgrund der Magnetkraft einander anziehenden Lagerelementen bildet, das die Lagerelemente voneinander beabstandet hält. Die magnetische Anziehungskraft zwischen den Lagerelementen ist dabei gleich der Summe aus der von der Masse und dem ersten Lagerelement ausgeübten Zugkraft und der Abstoßungskraft des Gaspolsters. Eine derartige Lageranordnung kann zur schwerkraftkompensierenden Aufhängung einer faltbaren Solarpanel-Anordnung (2) für einen Satelliten in einer Testeinrichtung für eine die Schwerelosigkeit simulierende Erprobung des Entfaltungsvorgangs in einem Gravitationsfeld verwendet werden oder kann allgemein als reibungsarmes Fördersystem dienen.
摘要:
An aircraft piloting method for improving a weightless condition, and a system therefor, wherein instead of being provided with information on the instantaneous position of the free-floating equipment (M), the pilot is provided with advance information on a future position of said equipment. The method is useful in weightlessness studies.
