At these very high vacuums the effect of photon radiation pressure on the vanes can be observed in very sensitive apparatus (see Nichols radiometer ) but this is insufficient to cause rotation. Source: Internet
At high altitude the four B-1A prototypes could achieve up to 2.2 times the speed of sound-assisted by two flexible vanes situated under the nose that help stabilize airflow. Source: Internet
As the rotor orbits, the vanes trap fluid between the rotor and the casing, drawing the fluid through the pump. Source: Internet
Although Lazar saw the aircraft for only a moment through the front of the bus, he described it as being "very large" and having "two huge, square exhausts with vanes in them". Source: Internet
A pair of small vanes mounted near the nose are part of an active vibration damping system that smooths out the otherwise bumpy low-altitude ride. Source: Internet
A wider view of the windmill was rendered on a Leavesden soundstage set with a quarter-scale windmill, complete with rotating vanes, painted sky backdrop and special-effects fire. Source: Internet
