T-Motor VZ38x15 VTOL 38 Zoll Carbon Propeller 1x CW 1x CCW

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

Blade Root Optimization:
Safety Redundancy Design

The blade root thickness is optimized to provide structural redundancy while reducing loads on the connecting bolts
