air stream

It involves breaking the blades down into small pieces and feeding them into a very hot air stream.

“When choosing a central air system, make sure it can mix filtered outdoor air with recirculated air in the recirculated air stream,” he says.

The fixed vanes behind the fan can change pitch so that they almost close together, blocking the air stream and serving as that brake.

“The Kinzhal does not waste energy to ascend. A jet fighter lifts it up to the air stream, up to the upper layers of the atmosphere where the air is thin,” Ihnat said, referring to the lower resistance levels at very high altitudes.

The first enhancement feeds to the jet’s flight computer a third measure of the jet’s angle of attack, the angle between the wing and the oncoming air stream, a key data point used in various control systems.
