The Generic Transport Model (GTM) has long been investigated in wind-tunnel studies and contributes today to an elaborated aerodynamic model. In this paper, we propose a novel approach for fitting the aerodynamic coefficients of the GTM, namely piece-wise polynomial identification, which considers measurements both of the pre-stall and post-stall region. This method provides a systematic approach to incorporate the full-envelope aerodynamics better than purely polynomial models. As a result, an analysis of the GTM’s full-envelope trim conditions has successfully been applied.
