Equations and graphs are provided for<br \/>\npredicting the trailing-vortex drag coefficient of wings with<br \/>\nquarter-chord sweep angles not exceeding 45\u00b0, aspect ratios not<br \/>\nexceeding 12, and linear or simple non-linear spanwise twist<br \/>\nvariations of up to 10\u00b0 wash-in or wash-out. ESDU 10022 is<br \/>\napplicable to both straight-tapered and cranked wing planforms<br \/>\nwhere the section geometry, including camber, either remains<br \/>\nunaltered or varies with spanwise location.<\/p>\n<p>The method is based on a theoretical analysis using inviscid<br \/>\nspanwise loading distributions generated by the Multhopp-Richardson<br \/>\nlifting-surface method, obtained from ESDU 95010. As a result the<br \/>\ntrailing-vortex drag coefficient obtained by the method is the<br \/>\ninviscid component of the total wing drag coefficient in shock-free<br \/>\nattached flow. The viscous drag coefficient, which is predicted<br \/>\nusing ESDU 07002, is the component of the total drag coefficient<br \/>\narising from all viscous effects. Therefore, ESDU 07002 can be used<br \/>\nin conjunction with the method of ESDU 10022 to predict the total<br \/>\nwing drag coefficient at a given value of <i>C<sub>L<\/sub><\/i> in<br \/>\na shock-free flow.<\/p>\n<p>Trailing-vortex drag coefficient data obtained using the Full<br \/>\nPotential (FP) program and a post processing program, both<br \/>\ncontained in ESDU 06016, are compared with data obtained using the<br \/>\nmethod of ESDU 10022.
