Influences of unsteady aerodynamic in conceptual design
(English)Manuscript (preprint) (Other academic)
Integration of unsteady and high-angles aerodyuamics is often done late in aircraft design. An attempt to integrate these aspects in conceptual and preliminary design is presented here. A simple aerodynamic model has been developed and used in conceptual design to study the influences of dynamic effects on platform geometry during high angular rate manoeuvres. In order to include these effects in conceptual design, flight simulation has been coupled with classic sizing and turn rate performance is included in the requirements for conceptual sizing. In one case, the sizing and simulation are performed with static aerodynamics, in the other case dynamic effects are included . The impact of large augular rate and its significance for open loop simulation is presented in the form of a pitch up manoeuver.
