This invention discloses a parametric design method for a helicopter particle separator. The method first sets control points at key locations and constructs the central body contour of the separator using a cubic Hermite interpolation polynomial with weighted terms. Next, based on the cross-sectional areas of key locations such as the separator inlet, bifurcation, and throat, the outer wall surface of the core region and part of the bifurcation profile are derived. Subsequently, by adding control points again and combining the cubic Hermite interpolation polynomial with weighted terms, a complete outer wall surface contour curve is generated. Simultaneously, the bifurcation curve is designed using circular arcs and tangents. This method not only meets the structural design requirements of the particle separator but also precisely controls the changing trend of its internal pressure gradient and supports flexible adjustment of key geometric parameters, thereby achieving efficient parametric design and optimization of the particle separator.
