Propeller and BLDC Motor Thrust Test Stand

Aero / MechatronicsMedium

Approx. component budget: Rs. 8,000 - 14,000

Objective

Measure thrust, power and efficiency for different propeller sizes and pitches at different throttle settings.

A rigid stand holding a BLDC motor with ESC and propeller on a load cell or lever arm, with a power meter, tachometer and throttle control.

Propulsion basics, drone design, load cell measurement and data analysis.

Load cell + HX711, power meter, tachometer, Excel. Use a strong shield around the propeller and keep clear while it spins.

Built and tested Propeller and BLDC Motor Thrust Test Stand; objective: measure thrust, power and efficiency for different propeller sizes and pitches at different throttle settings.
Measured and analysed thrust vs rpm and thrust per watt; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
