VZ SERIES-VTOL PROPELLERS

Break through the performance limitations of traditional multi-rotor propellers. VZ series propellers deliver superior power, durability, and lightweight design for VTOL applications.

What Does a VTOL Propeller Need?

  • 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
    Reduces the moment of inertia to achieve rapid thrust response and higher attitude control bandwidth for the flight control system.

Superior Aerodynamic Design

The unique dual operational modes of VTOL—vertical takeoff/landing and cruise—demand new propeller capabilities.

  • Vertical Takeoff & Landing Phase
    Requires 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.

Transition Stability: Resisting Complex Flow Field Interference

  • 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.

To address the challenges of traditional propellers in VTOL (Vertical Takeoff and Landing mode) applications, we introduce the VZ Series Propellers.

Technical Features of the VZ Series Propellers

  • Bending & Torsion Resistant Layup Design
    Optimized fiber orientation and ratio maximize strength and stiffness.
  • Prepreg Compression Molding for Integrated Forming
    Product porosity below 1%, ensuring stable and reliable quality.
  • PMI Foam Core
    Lightweight, high-strength core material effectively increases stiffness while controlling total weight.
  • 30% Flexural Strength
    Significantly enhanced impact resistance and deformation resistance for greater durability in complex operating conditions.
  • 20% Torsional Stiffness
    Optimized power transmission efficiency reduces energy loss during operation.
  • Blade Root Optimization: Safety Redundancy Design
    The blade root thickness is optimized to provide structural redundancy while reducing loads on the connecting bolts.
