Abstract : This patent discloses chemical laser nozzle blade support system which incorporates therein at least two continuous flexure member to secure the nozzle blades of the laser to the laser body. The blade and flexure member are formed with a radius, R, and each side of the member is supported by a surface having a radius, R1. Under nonstress conditions the blade and member are subjected to the same pressure and have the same radius of curvature. During operation of the laser, axial deflections occur which cause the blade end of the member to deflect in a radial manner which induces bending in the member. The magnitude of the bending stress is limited by establishing the value of R1 such that the change in radius of curvature cannot exceed a desired value. The resulting blade load is therefore primarily in tension with the only bending being that induced by the structural deflection.
