Experimental Research on Influence of Some Factors on Ejection Height of Cargo Projectile

Some factors influencing the cargo projectile’s ejection height in different conditions were analyzed by using harmonic curve diagram and cluster method.The test results of the ejection height for a certain cargo projectile show that the wind speed and direction are the main influence factors.For given meteorological conditions,the applied environmental stress becomes the main cause,while the launching angle does not influence the ejection height.
