A theoretical study of the aerodynamics of slender cruciform-wing arrangements and their wakes

John R. Spreiter, Alvin H. Sacks
Jan 1957

A theoretical study is made of the pressures, loadings, forces, and vortex wake associated with certain cruciform wing arrangements. For 45 degree bank, the wake of a cruciform wing is treated numerically with 40 vortices and analytically with 4 vortices. Comparisons are made with water-tank measurements, and the calculation of loads on cruciform tails by reverse flow considered.
