Vanes

However, if archers are using fletching made of feather or similar material, they may use same color vanes, as different dyes can give varying stiffness to vanes, resulting in less precision.

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.

The scope of supply includes the runners, guide vanes, turbine covers, shafts and bearings, as well as hydraulic and digital governors.

These guide vanes are just ahead of the fan assembly and prevented the spinner from actually entering the engine which would have caused a more drastic failure.

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".

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.

As the rotor orbits, the vanes trap fluid between the rotor and the casing, drawing the fluid through the pump.

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.

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.

Directly heated glass gives off enough infrared radiation to turn the vanes, but glass blocks much of the far-infrared radiation from a source of warmth not in contact with it.

Four solar panels were attached to the top of the frame with an end-to-end span of 6.88 meters, including solar pressure vanes which extended from the ends.

However, after the trial of these wheels, when the ship was drydocked, the majority of the vanes on each wheel were discovered to have broken off, and so the wheels were removed and the project abandoned.

If a person's hands are placed around the glass without touching it, the vanes will turn slowly or not at all, but if the glass is touched to warm it quickly, they will turn more noticeably.

If light pressure were the cause of the rotation, then the better the vacuum in the bulb, the less air resistance to movement, and the faster the vanes should spin.

If the vanes are made of metal, then the black or white paint can be the insulation.

In a transonic turbine the gas flow becomes supersonic as it exits the nozzle guide vanes, although the downstream velocities normally become subsonic.

In operation the moving vanes take up a physical angle equivalent to the electrical angle between the voltage source and the current source.

Inside the bulb, on a low friction spindle, is a rotor with several (usually four) vertical lightweight metal vanes spaced equally around the axis.

Multi-stage turbines have a set of static (meaning stationary) inlet guide vanes that direct the gas flow onto the rotating rotor blades.
