Jet air chimney pipe

We took a short drive to Rome, NY, to visit Griffiss Air Force Base Technology Park. Planes, especially military planes, just don’t float my boat. Real snoozers. But I have two sons who are crazy about machinery. Aren’t all boys? So this is for them.

Griffiss was an AFB for decades before the Clinton Administration downsized it. The city of Rome developed it into a technology park, and, among other things, also hosted a debauched rerun of Woodstock in 1999 here. The AFB was named for the first U.S. airman killed in action during WWII, Townsend Griffiss.

For most of its operation, the base was equipped with B-52 stratofortresses. All are gone except the “Mohawk Valley.”

An air door or air curtain is a device used to prevent air or contaminants from moving from one open space to another. The most common use is a downward-facing blower fan mounted over an entrance to a building , or an opening between two spaces conditioned at different temperatures.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines an air door as follows: "In its simplest application, an air curtain is a continuous broad stream of air circulated across a doorway of a conditioned space. It reduces penetration of insects and unconditioned air into a conditioned space by forcing an air stream over the entire entrance. The air stream layer moves with a velocity and angle such that any air that tries to penetrate the curtain is entrained. Air curtain effectiveness in preventing infiltration through an entrance generally ranges from 60 to 80%". [1]

The Air Movement and Control Association defines an air curtain as: "A directionally-controlled airstream, moving across the entire height and width of an opening, which reduces the infiltration or transfer of air from one side of the opening to the other and/or inhibits flying insects, dust or debris from passing through".
