Abstract:
1. A modular apparatus for simulating free fall in air comprising: a base structure that has a first center container and a second center container each of rectangular form with a general square width and height and an elongated length attached along an elongated side of each; a first side container attached to said first center container and a second side container attached to said second center container opposed to a center line of said attached elongated sides; a first inlet port of semicircular shape formed in a top wall of said first center container and a second inlet port of semicircular shape formed in a top wall of said second center container with said first inlet port and said second inlet port positioned to be adjacent along said attached elongated sides; a vertical duct of generally cylindrical form attached at an open bottom end over said first inlet port and said second inlet port wherein said vertical duct has a generally constant diameter cross-section with an open top end; and a fan with a connected power source positioned in each end of each of said first center container and said second center container to receive air from said each end that is open to cause a current of air to flow toward a center of each of said first center container and said second center container to be channeled upwardly to exit through said first inlet port and said second inlet port for air to flow through said vertical duct to exit said open top end.
