Abstract: ABSTRACT:In this paper, a design procedure for designing the inflowadapted
foil sections is presented. The design goal is to
design a foil section not only having a satisfactory
performance, but also having consistent performance at
different design conditions, for example, different speeds
or different angles of attack. We define foils designed
based on this design goal is an “inflow-adapted” foil.
Three design algorithms are described in the paper, and
they are design a foil based on the given pressure
distribution, single objective optimization based on the
Lagrange Multiplier method and an extended multiobjective
optimization method. A viscous flow RANS
method is used for the computation, and the cavitation is
also considered in the computations. The optimization
problem described in the paper is to satisfy the lift
requirement by minimizing the drag force, and design
examples of single objective are shown in the paper. A
multi-objective inflow-adapted foil design is also
presented. All the design cases show that the design
method presented in this paper is effective. The foil
sections designed based on the presented procedure are
expected to be used on propellers operated in a large
range of speeds or with the inclined shaft.
