Acoustic launch vibration is often the critical source of vibration for space telescopes. The large surfaces of membrane optics act as receivers of acoustic energy and can experience significant stresses on launch and significant displacements during laboratory testing. Using the finite element software MSC.NASTRAN, several membrane reflector geometries were analyzed under applied axial tension to the membrane surfaces. The pressure field was applied with a sin (kx)/(kx) spatial correlation. Stress and displacements were found at selected points on the membrane surface. Recommendations regarding membrane launch and laboratory testing states are presented in this paper.
