In this video, Tyto Robotics tests whether a single-blade propeller is more efficient than a standard two-blade design, using measured thrust, RPM and power data.
The team converts a Mejzlik two-blade propeller into a single-blade configuration with a counterweight, then balances it using the Flight Stand 15 thrust stand. Automated step tests are performed across multiple throttle points to directly compare performance.
Results show that RPM remains nearly identical at the same throttle settings, while the two-blade propeller produces significantly higher thrust. When efficiency is evaluated as thrust per watt, the single-blade propeller performs better at lower thrust levels, but the two-blade configuration becomes more efficient as thrust increases.
The test highlights how propeller configuration affects both thrust generation and efficiency, and demonstrates how theoretical expectations compare with measured performance.
