Abstract:
In order to evaluate the firing precision of long range multiple launch rocket systems(LRMLRS),a calculation and evaluation method of firing precision is proposed.The firing precision of LRMLRS with and without considering the system deviation is described distinguishly,and a calculation method is presented.The describition method of firing precision is transformed using the probability integral transition method.The firing precision can be evaluted using the tranditional evaluation method for firing dispersion.The mean square deviation σ' is characteriszed by the object points,the test of whether the system firing precision R satisfies the firing precision index R0 is transformed into the test of whether R corresponding to σ'satisfies R0.The mean square deviation of a non-full loading firing system σ'1 and the mean square deviation of a full loading firing system σ'2 are characteriszed by the object points,the test of whether the firing precision of the two systems is equal is transformed into the test of R1 corresponding to σ'1 and R2 corresponding to σ'2.The χ2 test can be used for testing whether the firing precision satisfies the index.In practical engineering,the evaluation of firing precision is realized,and experimental rockets are decreased by 58%.
