KFM has various meanings in the Blade category. Discover the full forms, definitions, and usage contexts of KFM in Blade.
Kline-Fogleman Modified (abbreviated as KFM) refers to a variation of the Kline-Fogleman airfoil design, originally developed for improving lift, stability, and efficiency in aircraft wings, but also adapted for specialized blades such as those used in drones, propellers, and certain industrial fans. The modification typically involves stepped or altered airfoil profiles that enhance aerodynamic performance, reduce drag, or improve control at lower speeds. In blade applications, KFM designs can be customized to meet the unique aerodynamic demands of the device, from model aircraft to UAVs.
The KFM approach is particularly valued in hobbyist aviation and unmanned aerial systems because it allows for simpler manufacturing—often from flat materials—while maintaining solid aerodynamic characteristics. The modified version may incorporate changes in step placement, camber, or thickness to optimize performance for a specific use case, whether that’s higher speed, improved lift, or energy efficiency.
