ELLIPTICAL EQUATIONS FOR FREE FLIGHT: A TREATMENT SHOWING EQUALITY BETWEEN THREE SYSTEMS OF ELLIPTICAL EQUATIONS,
Abstract
At the present time, there exists within Systems Analysis Laboratory three sets of elliptical equations for free flight range and time of flight. The equality that exists between the three sets is shown. The three sets in question are those by Johnston (OML Rpt. 6R7F), Powell (SAL Internal Note) and Wheelon (ARS Journal, Vol. 29, December 1959). The free flight range, , as given by each set, is sshown to be equal for all sets by first equating Johnston and Powell, then Powell and Wheelon. The time of free flight is shown to be equal between Johnston and Powell. Wheelon's equations for time are written for the time from launch to impact, and therefore are not shown here. (Author)
