This chamber, 160 feet long, 11 feet high and 16 feet wide, holds more than twice as much air as the high-speed corridor and generates winds with a top speed of 23 mph.
A removable floor covers the 250,000-gallon tank, which has a wave maker for the study of offshore structures.
The key to the wind tunnel, the contraction is the nozzle through which air is forced to increase its velocity as it passes into the high-speed corridor.
Eight feet in diameter, the 289-horsepower electric fan sucks air through the test center at a rate of up to 400,000 cubic feet per minute.
Amen Corner, at last
SI's model was tested in this staging area. The rotating floor allowed the wind to hit the model from any direction.
The 704 steel boxes (each two by four inches) can be adjusted to simulate gusts.
This chamber, 128 feet long, 6 feet high and 11 feet wide, can produce winds up to 62 mph.
