English

Subject field(s)
  • Bearings and Bearing Systems (Mechanical Components)
  • Electric Rotary Machines
  • Wind Energy
DEF

[An arrangement of] bearings that supports a [wind turbine’s] horizontal shaft.

CONT

Pillow block bearings are a form of mounted bearing used to provide load support for a rotating shaft axis. The bearing housing mounts to a surface parallel to the shaft axis. Selection of the appropriate bearings can be accomplished based on the shaft size and the radial and thrust load requirements. Pillow block bearings are designed to support a shaft : the mounting surface is on a parallel line with the axis of the shaft.

Record 7 2004-05-03

English

Subject field(s)
  • Launchers (Astronautics)
CONT

Magnetoplasmadynamic(MPD) thrusters pass a large current radially outwards through a neutral plasma, from a central cathode to an annular anode. The radial current induces an azimuthal, circular magnetic field. The Lorentz body force acting on ions moving in the discharge current accelerates the plasma along the axis of the electrode structure. MPD thrusters operate at high power levels, kilowatts to megawatts, and provide high thrust with moderate specific impulse. A variant of this design uses an externally applied magnetic field to enable operation at lower power levels. MPD thrusters have been tested in the laboratory and have flown on test and demonstration missions. MPD thrusters are an insufficiently mature technology and consume too much power to be considered as candidates to provide primary propulsion of future out of Earth orbit missions and were not considered for SMART-1.

Record 10 1988-12-22

English

Subject field(s)
  • Joining Elements (Mechanical Components)
DEF

A screw thread whose forward face is perpendicular to the screw axis and whose back face is at an angle to the axis, so that the thread is both efficient in transmitting power and strong.

CONT

The buttress or breech-block thread is designed for transmitting an exceptionally high pressure in one direction only. In its original form the pressure flank was perpendicular to the thread axis, and the trailing flank sloped at 45°. To simplify the cutting of the face, modern practice is to give the pressure flank a 7° slope. This form of thread is applicable for assembled tubular members because of the small radial thrust. Buttress threads are used on breech mechanisms of large guns and for airplane propeller hubs.

Record 11 1986-09-26

English

Subject field(s)
  • Flight Instruments and Equipment (Aeroindustry)
CONT

Several new functions have been integrated with the flight-management computer with the result that it has been renamed the Flight Management Guidance Computer(FMGC). The Flight Management Guidance Computer supplies command signals to the pitch and roll surfaces through the fly-by-wire computers and to the yaw axis through the flight-augmentation computers. Thrust management is vested in the FADEC engine controllers.

French

Domaine(s)
  • Instruments et équipement de bord (Constructions aéronautiques)
CONT

Le calculateur du FMS intègre quelques fonctions nouvelles, ce qui a amené à le rebaptiser FMGC (Flight Management Guidance Computer = calculateur de guidage et de gestion de vol). Le FMGC fournit les ordres de tangage et de roulis au travers des calculateurs des commandes de vol électriques, et contrôle le lacet par l'intermédiaire des calculateurs de stabilisation. La gestion de la poussée est confiée au système FADEC.
