Abstract: An apparatus for testing failure of a material used in a jet engine, and more particularly to an apparatus that uses one or more miniature jet engine components made from a material used in a full-size jet engine and desired to be tested. The apparatus permits easy removal and disassembly of a jet engine mounted thereon as well as real-time measurements of run-time parameters. The methods and apparatus provide for predicting and analyzing failure by a number of fatigue-related mechanisms including creep, fatigue, crack growth, foreign object damage, fretting, erosion, and stress corrosion. The apparatus also permits testing of a component placed in the exhaust gases of a jet engine mounted therein.

Abstract: A portable spa comprises a reservoir for holding water and an outer wall spaced outwardly from the reservoir. The spa includes an equipment bay located between the reservoir and the outer wall that is accessible from an opening at a top portion of the spa. A cover over the opening to the equipment bay is removable from the top portion of the spa to permit access to the equipment bay. The equipment bay contains substantially all of the equipment necessary for operation of the spa and can be conveniently accessed free of any obstructions around the side of the spa. The spa can be installed either above ground in the manner of a portable spa, or it can be installed directly in the ground in the manner of a permanent in-ground spa. Reinforcing means comprising an internal support framework supports the spa against the lateral external forces generated as a result of in-ground installation.
