DEF

A strut or tie running at an angle to both the horizontal and the vertical in a lattice girder.

CONT

A simple truss such as the Howe truss extends between two supports. In this truss, the top chord resists the compression forces, the bottom chord resists the tension forces, and the diagonal web members between the chords resists the shear forces.

Subject field(s)
  • Orbital Stations
CONT

This truss segment, called "P1," is a 46-by-15 foot structure weighing about 32,000 pounds when fully outfitted and ready for launch.

CONT

The P1 Truss, the first port truss segment, was attached to the port side of the S0 truss ... The P1 Truss provides structural support for the Active Thermal Control System, Mobile Transporter and one Crew and Equipment Translation Aid cart. ... The P1 Truss also has mounts for cameras and lights, and antenna support equipment for both UHF [Ultra High Frequency] and S-band communications equipment. The S-band equipment is currently on the P6 Truss.

CONT

The main truss segments-S0, P1, S1, P3, and S3-were designed as rigid hexagonal sections; a six-point structure is more rigid than one with four points. The hexagonal cross section also maximizes the volume that can be used to load equipment onto the truss. A square will not use the available volume as well as a hexagon.... The truss segments are not regular hexagons; the sides are not equal in length. The segments are wider than they are tall to further exploit the Shuttle payload bay area...

OBS

P1 truss; integrated truss structure P1; P1; ITS-P1: terms and abbreviations officially approved by the International Space Station official approval Group (ISSOAG).

[...] l'équipage de STS 113 installeront le troisième segment de l'immense poutrelle qui portera éventuellement les panneaux solaires (générant l'électricité) et les grands radiateurs (évacuateurs de chaleur). Il s'agit de la pièce dite P1, la première portion bâbord (gauche) de la poutrelle. Ce segment est identique au S1 (premier segment tribord, droit) installé en octobre. Au terme de cette opération d'assemblage, la poutrelle mesurera 40,5 mètres (elle fera, à terme, 108 mètres).

The truss segments are not regular hexagons; the sides are not equal in length. The segments are wider than they are tall to further exploit the Shuttle payload bay area... The hexagonal truss segments also contain a robotic manipulator arm that travels along two longerons on one plane of the hexagonal truss. The 55 ft(17 m) long robotic arm being built by the Canadian Space Agency will be launched with the S0 segment and will travel the length of the truss.

Record 7 2001-10-25

Subject field(s)
  • Orbital Stations
CONT

The P6 truss ... houses a deployable radiator. Ammonia coolant lines from the U.S. laboratory module ultimately will be connected through the Z1 truss to the radiator to dissipate heat generated by the lab’s electronic gear. At launch, P6 weighs 17.5 tons and measures 16-by-16-by 49 feet.

CONT

The P6 truss will connect to Z1 to provide auxiliary power for station construction and primary power to the U. S. laboratory that will be attached to the Unity module early in the launch schedule. When the station is nearly fully assembled, P6 will then be removed from the Z1 truss and placed in its final position on the end of the station's main truss. The rectangular coupling where the P6 segment was attached to Z1 will remain unoccupied.

OBS

The P6 truss is a component of the photovoltaic module.

À l'aide du Canadarm, Garneau saisira [...] la poutrelle P6 - une section de la poutrelle principale de la station sur laquelle les panneaux solaires ont été fixés avant le lancement. Garneau amènera ensuite l'ensemble, qui pèse 16 000 kilogrammes et mesure environ 14 mètres de longueur, à quelques centimètres à peine d'une autre section de poutrelle qui fait déjà partie de la station. Appelée Z1, cette section est munie d'un système d'attache en forme de pince qui sera utilisé pour saisir P6 et la maintenir en place.

Subject field(s)
  • Launching and Space Maneuvering
  • Orbital Stations
CONT

The description of the Station's flight attitude(orientation relative to the plane of its orbit) is referenced to local-vertical/local-horizontal(LVLH) axes that are fixed with respect to the Station's near-circular orbit(i. e., not to the physical Station). The LVLH origin is at the Station's center-of-mass; the z-axis points radially toward the Earth's center(or toward the nadir direction), the x-axis points along the orbital velocity vector(the ram direction, with wake being opposite), and the y-axis completes the right-handed triad. The flight attitude of the Station is then described using a second, Station-fixed, coordinate system whose orientation relative to LVLH is specified using the Eulerian angles of yaw, pitch and roll. Several Station-fixed coordination systems are defined. The most widely used is the Space Station Reference Coordinate System,... in thich the positive x-axis points along the axis of the U. S. lab away from the Zarya and Service Modules; the positive y-axis points starboard along the main truss, and positive z completes a right-handed coordinate system.

OBS
