High Strength
Withstands immense centrifugal loads and maneuver-induced alternating loads at high RPM, preventing structural failure
High Stiffness
Ensures safe blade-tip clearance in compact layouts, suppresses aeroelastic deformation, and prevents flutter
Lightweight Design
Reduce the moment of inertia to achieve rapid thrust response and higher attitude control bandwidth for the flight control system
Vertical Takeoff &
Landing Phase
Requiring high thrust and power, demanding maximum lift output from the propeller disk within a limited blade area
Cruise Phase
When the propeller stops rotating, it is necessary to minimize profile drag to reduce power consumption, achieving "stealthy" low-drag efficiency
Unsteady Flow Fields
at High Angle of Attack
The aircraft operates at high angles of attack and low speeds within an extremely complex flow environment
Asymmetric Airflow
Significant angle between incoming flow and the rotation axis causes asymmetric airflow entering the propeller disc
Severe Periodic
Variations
Local forces on the blade fluctuate drastically per rotation, inducing flutter and causing significant thrust fluctuation
Bending & Torsion Resistant Layup Design
Optimized fiber orientation and ratio maximize strength and stiffness
