In order to find out rational analytic function empirical formulas of projectile air resistance law and aerial bombs resistance law in 1943 in the whole definition domain to proceed numerical calculation of exterio trajectory and analytical solution by computer programming, using 1stOp mathematical software was used to fit curves of projectile air resistance law in 1943 and aerial bombs resistance law in the whole definition domain. Rational analytic function empirical formulas common to the whole definition domain was got corresponding to the resistance laws. These empirical formulas are no longer segmented. The maximum relative error of empirical formula fitting projectile air resistance law in 1943 was 3. 271%, and the maximum relative error of empirical formula fitting high resistance aerial bomb and low resistance aerial bomb air resistance law were 1.914% and 3.328% respectively.
