Bruce C. Andrew The ROTOR CODE is a FORTRAN program written to accept input of basic rotor geometric parameters plus a set of airfoils and to output cross-sections obtained by applying a parametric tension spline interpolation technique. A flowchart for ROTOR is given as a list of major subroutines. Each major subroutine is explained and detailed user instructions given. The primary output of ROTOR is XY airfoil coordinates
at specified span-wise stations which can be used to make templates to be used in constructing a mold for rotor fabrication.
