Low Noise Propellers for UAV

Propellers and
Propeller Systems

Variable Pitch | Constant Speed Propeller Systems

Variable Pitch Propeller systems have been available for larger aircraft for years, and now small UAVs can benefit from this technology. The NWUAV Variable Pitch System system can be bolted onto any engine that is strong enough to turn it and utilize the benefits of variable pitch. The ability to custom design this system ensures that the customer gets the proper blades with the required length and twist. Optimized engine performance with lower engine speeds, added launch thrust and a decrease in acoustic signature, makes this system an excellent choice for small UAVs
