Aerodynamic Propeller Optimization
Redesigned airfoil and load distribution reduce tip vortices and airflow separation, the primary noise source.
City Solution
Silent Urban Operations– Only 67 dB at 5 Meters
Before, drone noise was too loud
once airborne, residents complained, making urban projects impossible. Now, the i-Series quiet propeller design drops noise to just 67dB at 5 meters—quieter than a car—so UAVs can finally serve cities without disturbance.
Multiple Real-World Tests
67dB measured at 5m (ambient 50dB), 10dB quieter than standard props, validated by client field tests.
Low-Vibration Motor Design
High-precision balancing and integrated structure keep vibration below 0.5mm/s, cutting mechanical noise.
Quiet Performance Without Trade-Offs
Delivers lower acoustic signature without sacrificing usable thrust, endurance, or flight stability—making urban UAV operations more practical and commercially viable.
Recommended Low-Noise Products
The i Series brings all-in-one propulsion to urban multirotor platforms with ultra-quiet propeller design for city missions.
Recommended Models
Low-noise i Series propulsion for city, inspection, and public-area missions.
i5
Low-noise motor for city multirotors.
i7
67 dB Low-Noise Performance for Urban Multirotors
Customer Case
Quiet Enough in the Air.
We're an urban traffic patrol service provider, working with traffic authorities to monitor busy intersections during rush hours. Our old motors were too loud—fly low and you disturb the public, fly high and you can't read license plates. Pretty awkward. Since switching to IPET's motors and props, the noise has dropped significantly—hovering above intersections, you barely hear a thing, no disruption to drivers or pedestrians. The footage stays steady, capturing illegal parking and spotting congestion points with clarity. The traffic department appreciates that we can now do our job quietly without complaints rolling in. It just works.
