ABSTRACT:
Apparatus for preventing a missile's rocket exhaust gases from contacting and adversely affecting, such as by overheating, the launch rails from which a missile may be launched. Such apparatus includes an angled member having first and second leg portions, the end of the first leg portion being pivotably secured to the rail. A member having an angled surface is mounted to the second leg portion. Prior to the launching of said missile, the apparatus is in a first operative position such that it is out of contact with said launch rail. When the exhaust gases are emitted from said missile, a portion of the exhaust is incident upon the angled surface which causes the apparatus to rotatably pivot into contact with the launch rail, whereby portions of two surfaces of the launch rail are protected from the exhaust. In alternative arrangements, springs or counterweights are provided to hold the protective apparatus open to facilitate loading of a missile on the launch rails while permitting the apparatus to close around the rails when the missile is being launched. Other arrangements provide for translation as well as rotation of a pair of angled members in a clam shell configuration for protection of particularly shaped launch rails.
