The modelling of the nonlinear lift and pitching moment characteristics of 60 degree delta wings and wing-bodies is addressed. Using experimentally measured lift data of a 60 degree delta wing, the applicability of mathematical models proposed in the literature for sharp-edged delta wings is examined and an alternate simple model structure is proposed. Based on this, models for the lift and pitching moment characteristics of a 60 degree delta wing-body are developed using experimental data. This lift model structure is extended to incorporate the effect of trailing edge control surfaces and models fitted to the experimental data of a 60 degree delta wing-body with trailing edge control surface. The proposed model structure is able to characterize quite accurately the nonlinear lift and pitching moment characteristics of 60 degree delta wing/wing-body and simplifies to a classical derivative model at low angles of attack.
