ANALYSIS OF MISSILE LAUNCHERS. PART P. EFFECTS OF RANDOM THRUST
ILLINOIS UNIV URBANA
Pagination or Media Count:
An analysis is presented of the statistical variation of the tip-off angle and angular velocity of a missile due to fluctuations in the thrust force. The single degree of freedom launcher model is employed, and the thrust function is assumed to be the sum of two functions, one of which is of constant form from launch to launch, and the other representing the random time-dependent fluctuations. Under these assumptions two variations in tip-off conditions are present, one due to the change from launch to launch in average value of thrust, and a second due to rapid time-dependent variations. Expressions are derived for the mean values and variances of the tip-off angle and velocity using some techniques of information theory. Author
