DESIGN OF SUITABLE ASYMPTOTIC COURSES OF METEO-BALLISTIC WEIGHTING FACTOR FUNCTIONS FOR SENSITIVITY ANALYSIS OF PERTURBED PROJECTILE TRAJECTORIES
Rozehnal O., Čech V.
pages 440 - 443, full text

This paper is a free continuation of the paper at Engineering Mechanics 2014 by Čech, Jevický and Jedlička. In practice, various relationships are used to sensitivity analysis the effect of meteo conditions on the uncontrolled projectile trajectory, all of which are derived from the corresponding Weighting Factor Functions - WFFs. One of the ways to analyze the influence of the trend of meteo conditions on the projectile trajectory is the use of simplified - asymptotic courses of WFFs. Thus, for example, Weighting Factors - WFs for STANAG 4061 were created in this way. In the article, we deal with the analysis of the properties of one group of asymptotic WFFs, which is suitable for surface-to-surface fire and the effect of wind on the projectile trajectory with altitude up to cc. 10 km (range up to cc. 30 km) and virtual temperature up to altitude cc. 6 km (range up to cc. 20 km). From the given WFFs, the corresponding systems of WFs are easily calculated. At the same time, we present the relations for the calculation of the Reference Height of projectile trajectory, which is given in the tabular firing tables according to the Soviet methodology.
