Abstract

With the relentless pressure to drive down the weight of aircraft in the pursuit of increasing fuel efficiency, accurate weight estimation is needed as early as possible in the design cycle. Multidisciplinary design optimization of wings is currently fidelity inconsistent – optimization of the load-bearing structure and aerodynamics are often performed to a high degree of precision with Reynolds-averaged Navier-Stokes solvers and finite element models for the structure. Meanwhile, estimation of non-structural weight including the high-lift system uses low fidelity correlations and rules of thumb. A preliminary estimation tool for high-lift actuation weight and sizing based on aerodynamic loads is demonstrated using two different test cases: an under-development narrow-body airliner and the NASA Common Research Model high-lift configuration.
