Roll Effects on Carryover for Hypersonic Delta Fin Missiles

Abstract

An Euler code is used to predict hypersonic missile flowfields and to determine the carryover factors for the effect of the body on wing lift KW(B) and for the effect of the wing on body lift KB(W). Results are presented for Mach 4, 6, 8, and 10 at an angle of attack of 2 deg. The missile has a conical nose, a cylindrical fuselage with a 1-deg flare angle, and delta fins. Both x and + fin configurations are considered. Results are given for 20- and 30-deg semivertex angles as a function of finspan to body radius (at fin leading edge), S/RLE. The wing-body carryover for x fins is smaller for the top set of fins than it is for the bottom set of fins. The value of KW(B) for the missile with x fins is slightly larger than it is for + fins at Mach 8 and 10. At Mach 4 and 6, KW(B) is independent of fin configuration. KB(W) is larger for x fins than it is for + fins, and it increases as semivertex angle decreases from 30 to 20 deg. KB(W) generally decreases as both Mach number and finspan increase. Equations and tables are presented for the carryover factors.
