Wings are
main elements of pomps, water mills, turbines,
compressors, propellers and windmills. It has the function that generates
lifting force, and convert fluid energy into
mechanical energy and vice versa. Wings that have the ends in
the flow, and changes the flow situation along wingspread, are called
three-dimensional wings. The flow pattern is extreme different from the two-dimensional wings that correspond to the wing with a infinite
wingspread .In the present study, the flow around a three-dimensional wing is
analyzed by the vortex lattice method using the spreadsheet under the assuming of
potential flow. As a result, velocity distribution, pressure
distribution and lift force aroud the wing can be
calculated .In spreadsheet, calculation procedure can
be understood easily. So itfs not necessary for users to acquire any program
language.
