✅ 31 inch | ✅ Max Thrust 21kg | ✅ Impact Buffer Plate for Motor Protection | ✅ Double Anti-loosening Shaft
Industry Pain Points
Structural Failure Risks During Long-Time Operation
Under continuous cyclic load of heavy-lift UAV operation, the prop hub tends to suffer fatigue fracture. Sustained vibration loosens prop clamp threads and brings critical flight safety hazards.
Collision Damage & Insufficient Power Performance
In field collision incidents, impact force transmits directly to the motor, which is likely to burn out the motor and result in high maintenance costs. Conventional folding propellers feature poor aerodynamic efficiency and limit flight endurance & payload capacity.
Functional Features
FOUR HIGHLIGHTS：
1、Blade Tip Aerodynamic Optimization
2、Reinforced Prop Hub
3、Exclusive Buffer Plate
4、Dual-Lock Damping Prop Clamp Assembly | Anti-Loosening & Vibration Damping for High Reliability
1 Blade Tip Aerodynamic Optimization
Downward Winglet Tip Design | Higher Aerodynamic Efficiency & Reduced Tip Vortex
Optimized via multiple rounds of CFD simulation with downward winglet configuration.
Improves tip airflow distribution and suppresses tip vortex.
Boost thrust under the same power consumption, cut induced drag, extend flight endurance and reduce noise.
2 Reinforced Prop Hub
Reinforced Prop Hub | For High Cyclic Load Conditions
Thickened hub structure with upgraded composite material formula.
Greatly improves fatigue life under cyclic load, supports continuous high thrust & coaxial power system.
Reduce risk of hub fracture during heavy-load hovering.
3 Exclusive Buffer Plate
T-MOTOR Exclusive Buffer Plate | Absorb Impact & Protect Motor
The buffer plate acts as an independent shock absorber.
When collision occurs, the plate deforms and shears to dissipate impact energy.
Reduce shock transferred to motor, lower motor failure probability and cut maintenance cost.
4 Dual-Lock Damping Prop
Clamp Assembly | Anti-Loosening & Vibration
Damping for High Reliability
Aluminum shaft reduces blade wear. Dual-lock fasteners resist continuous vibration to prevent thread loosening. Built-in wave spring shims deliver damping, cut vibration transfer and extend service life of the prop assembly.
