Product overview
The T-MOTOR AUZ 21*16 is a one-piece carbon-fiber propeller for electric fixed-wing UAVs, including conventional, flying-wing and VTOL layouts. Its 21-inch (533.4mm) diameter and 16-inch (406.4mm) pitch support applications spanning logistics delivery, surveying and exploration, power-line inspection, agricultural crop protection, emergency rescue and security monitoring. A dedicated airfoil is designed to improve aerodynamic efficiency and reduce noise. Recommended motor combinations pair the AUZ21*16 with an AT5230, AT7215 or AT7224, and mounting uses center locking on a Ø10mm motor shaft.
The matte-finished propeller combines a resin-based carbon-fiber composite with a PMI sandwich core and weighs an average of 60 g per propeller. Prepreg compression molding forms the structure as one piece, with porosity below 1%. Its layup uses optimized fiber directions and proportions to resist bending and torsion. The operating temperature range is -30°C to 60°C. Recommended maximum rotational speed is 8440 RPM, with a limit speed of 9700 RPM; recommended maximum thrust is 20.8 kg, with a limit thrust of 26 kg.
