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
High Stiffness &
Lightweight Design

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

Superior Aerodynamic Design

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

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

Transition Stability: Resisting Complex Flow Field Interference

The extreme challenges posed by high angle of attack, low speed and unsteady flow field,
coupled with the insufficient strength and poor transition stability of traditional blades,
make this an accident-prone region

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
