摘要:
One aspect of the present invention involves a hold-down and release mechanism ("HDRM") that includes a hold-then-release mechanism configured to hold an element until the hold-then-release mechanism is commanded to release the element; and an integral sensor configured to sense an amount of a parameter of interest associated with the HDRM and to communicate the sensed amount of the parameter of interest to a receiving device. The parameter of interest comprises one of tensile preload, temperature, vibration, shock, and time from application of an HDRM firing current to HDRM release of the element.

A separation device according to the present invention includes: an outer case (110); a pillar-shaped separation member including an engaging portion (101a); a support member (102) including a swinging portion (102b) and an engageable portion (102a), the swinging portion (102b) being swingably supported by the outer case (110), the engageable portion (102a) supporting the separation member; an inner case (103) including a fitting hole (103a) restricting swinging of the support member (102); and an operation-enabling element (111), which supports the inner case (103) and which is fusion-cut when an electric current is applied thereto. When the operation-enabling element (111) is fusion-cut, the inner case (103) is displaced, such that: the engageable portion (102a) of the support member (102) detaches from the fitting hole (103a); the swinging portion (102b) swings; and the engageable portion (102a) moves away from the engaging portion (101 ) to release the separation member.

A spacecraft (10) for removing space debris is disclosed. The spacecraft includes a satellite bus (100), a shield member (110) foldable on an outer side face of the satellite bus and disposed facing towards space debris to reduce a movement speed of the space debris, and a support member (120) configured to support the shield member with respect to the satellite bus, in which the shield member includes a central panel (112) configured to overlap one face of the satellite bus, a plurality of first panels (114) connected to peripheral sides of the central panel and radially extended, and a plurality of second panels (116) located between the first panels.
摘要:
A space-based solar power station, a power generating satellite module and/or a method for collecting solar radiation and transmitting power generated using electrical current produced therefrom is provided. Power transmitters can be coordinated as a phased array and the power generated by the phased array is transmitted to one or more power receivers to achieve remote wireless power generation and delivery. In many embodiments, a reference signal is distributed within the space-based solar power station to coordinate the phased array. In several embodiments, determinations of the relative locations of the antennas in the array are utilized to evaluate the phase shift and/or amplitude modulation to apply the reference signal at each power transmitter.

La présente invention a pour objet un dispositif de motorisation comprenant deux cylindres d'enroulement (1a) sensiblement parallèles, au moins des moyens d'enroulement formant élément de liaison de forme longitudinale, les moyens d'enroulement étant aptes à maintenir une distance prédéterminée entre les cylindres d'enroulement (1a) et étant enroulés autour des cylindres d'enroulement (1 a), et au moins deux pistes flexibles (2a), une piste flexible (2a) étant fixée sur chaque cylindre d'enroulement (1a), les pistes flexibles (2a) étant disposées en vis-à-vis et présentant un point de contact, un effort de précontrainte s'appliquant audit point de contact des pistes flexibles (2a) sous l'effet des moyens d'enroulement, caractérisé en ce que le dispositif de motorisation comprend des moyens élastiques (30) disposés entre chaque cylindre d'enroulement (1a) et la piste flexible correspondante (2a), les moyens élastiques (30) étant configurés de manière à exercer un effort radial de compression sur chaque piste flexible (2a), normal à la surface de la piste flexible (2a) au moins au niveau dudit point de contact.
摘要:
The present invention provides a capture mechanism for capturing and locking onto the Marman flange located on the exterior surfaces of spacecraft/satellites. The capture mechanism achieves its goal of quickly capturing a client spacecraft by splitting the two basic actions involved into two separate mechanisms. One mechanism performs the quick grasp of the target while the other mechanism rigidises that grasp to ensure that the target is held as firmly as desired.
