Abstract: Aiming at the problem that currently the fuze turbine structural parameter design mainly depends on expe-
rience and experiment, based on optimization theory, the design flow and method for fuze turbine parameter multivari-
able nonlinear optimization is proposed. The goal is that the turbine speed-projectile velocity curve has the best line
arity; and three parameters are optimized, which are the number of blades N, blade lead La and blade thickness t,. The
model was assembled and water tunnel simulation tests were conducted. The experiment results show that before and
after optimization, the non-linearity coefficients of the turbine speed-projectile velocity curves are 0.992 and 0.996
respectively the optimized turbine has better performance; the proposed optimization design method is feasible and
has an engineering practical application value
