| Missile Impact Facility (MIF)
This facility allows a high-speed release of various missiles. Its
main components are: a nitrogen gas powered cannon equipped with a
"poppet valve", a confining tube, and electro-mechanical
set-up to precisely measure the speed of the released missile. A modular
design of MIF makes possible testing employing different
missiles.

For impact studies of tornado-generated missiles, the cannon is
furnished with a long confining tube. This arrangement allows for
precise release of a standard "tornado missile" - a 2
inch by 4 inch, 12 feet long timber plank. The missile speed in excess
of 110 mph is achievable using this arrangement. A tested specimen is
attached to a supporting frame placed at a distance of 6 feet from the
exit of the confining tube. |
