As a result of supercavitating projectiles with high underwater velocity  their structures undergo high longitudinal force. It is necessary to perform structure buckling load interval analysis because the uncertainty of structural own parameters should be considered. Critical buckling load of supercavitating projectiles is calculated by Galerkin method. The partial matrixes of critical buckling load implicit function to each uncertainty variable are deduced  and the interval of structure critical buckling load is calculated by interval analysis and convex model methods. Numerical results show that the nominal value  lower and upper bounds of critical buckling load increase with the increment of the ratio of base diameter to cavitator diameter. And the uncertainty degree of basic variables should be controlled as far as possible in the project for high reliability. 2011 IEEE.

Because the underwater velocity of supercavitating projectile is very high  its structure undergo high longitudinal force. It is necessary to perform structure buckling reliability analysis because the randomicity of structural own parameters and flow parameters should be considered. Critical buckling load of supercavitating projectile is calculated by Galerkin method. The partial matrixes of critical buckling load implicit function to each random variable are deduced  and structural buckling reliability index is calculated by limit step length iteration method. Numerical results show that the critical buckling load and structural buckling reliability index increase with the increase of the ratio of base diameter to cavitator diameter. And structural buckling reliability index increase with the decrease of velocity coefficient. 2011 IEEE.

Corrective force solving is a critical technology of the active optics. A method to solve active optics corrective force is introduced  which is based on Householder transform of Zernike polynomial wave front fitting  this method is different from the traditional least square method and Gram-Schmid orthogonal method  because it does not bring ill-conditioned polynomial without constructing normal equation  so it can avoid calculation error  wave front fitting is precision. Based on the coefficient of the Zernike polynomial and the response function of the each actuator  the stiffness matrix of the primary mirror is built  and then adopting the damp least square method to calculate corrective force. Based on this method  cp400m test mirror is simulated many times  the calculation result approve: if the Householder transform is adopted  wave front fitting is precision  the result is stabilization and corrective effectiveness is better.
