抄録

This paper presents some additional numerical results to our previous papers, concerning about a new computation method for unsteady subsonic lifting surfaces, BIS (Box-in-Strip). It consists of two parts. The one is comparisons between BIS and PCKFM (Piecewise Continuous Kernel-Function Method), which seems to be appreciated as an excellent method in USA. The other is comparisons between BIS and analytical solutions for circular and/or elliptic planform wings in steady incompressible flow. As a result, it is found that PCKFM yields fairly close results to BIS in the case of the rectangular wing with AR=10 and that correlation between BIS and analytical solutions is much more excellent than VLM. Thus we confirmed again the superiority of BIS over VLM.
