The LOFT Modular Drag Disc Turbine Transducer (MDTT) springs (for range 2, rhoV/sup 2/ = 4900 lbm/ft-sec/sup 2/) were analyzed to determine the static rhoV/sup 2/ load needed to cause a buckling failure. The static load needed to cause elastic buckling was found to be equivalent to a rhoV/sup 2/ value of 431,000 lbm/ft-sec/sup 2/ according to classical buckling theory, but could be as low as rhoV/sup 2/ = 100,000 lbm/ft-sec/sup 2/ due to uncertain end fixity and other spring imperfections.
