Damping-in-roll calculations for slender swept-back wings and slender wing-body combinations

Harvard Lomax, Max A Heaslet

Abstract

The damping-in-roll parameter C(iota)(p) is calculated theoretically for triangular wings on cylindrical bodies and for a class of wings with sweptback plan forms. The analysis is based on the usual assumptions of linearized compressible-flow theory together with the added restrictions that at the free-stream Mach number M(omicron) the product of lM(omicron)(2) and the streamwise velocity gradient is small.
