dc.description An invited paper with the results of collaboration between TsAGI, Russia and DMU, UK, funded by DERA/QinetiQ, Bedford UK. The phenomenological approach formulated to nonlinear unsteady aerodynamics modelling is adopted in DLR/Germany (R.V. Jategaonkar jategaonkar@dlr.de), ADA/India (Program Director T. G. Pai tgpai@iitk.ac.in ), presented in “Aircraft System Identification: Theory and Practice” by V.Klein and E.A.Morelli, AIAA Education Series, 2006, pp.484 (see p.59 and 72). The experimental technology for real-time unsteady loads measurements using hot-film sensors has been “...inspired by Goman and Khrabrov’s work…” (see NASA/TM-2004-212854, pp. 3-4, http://www.nasa.gov/centers/dryden/pdf/88785main_H-2568.pdf). en
dc.description.abstract An adequate modelling of nonlinear and unsteady aerodynamics at high incidence flight is important for design of future agile and stealth fighters as well as for improved prediction of high angle of attack dynamics of normal aircraft configurations. The limitations for conventional aerodynamic model based on aerodynamic derivatives concept are analyzed considering the longitudinal motion of a hypothetical aircraft with the 65 degree delta wing and thrust vectoring control. The dynamic unsteady aerodynamic model approximating the vortical and separated flow time lag effects is considered along with the conventional aerodynamic model and their impact on aircraft dynamics and control law design is discussed.
