Long-Endurance UAV Propulsion Solution

Extend Useful Flight Time for Industrial UAV Missions

IPET I Series and IV Series combine efficient motor design, integrated or matched ESC architecture, and optimized propeller sizing for multirotor and VTOL platforms that need to cover more distance, remain on station longer, or reduce battery-change interruptions. Configuration is selected around practical hover or cruise load rather than maximum-thrust figures alone.

Longer Endurance Means More Work per Flight

Endurance is the result of aircraft weight, propeller loading, battery platform, propulsion efficiency, and mission profile. IPET focuses on system efficiency at practical operating points so teams can extend route coverage and on-station time without trading away thermal margin or control stability.

Power Grid and Transmission Line Inspection

Mission Challenge

Long transmission corridors, mountainous terrain, and limited landing zones make repeated battery changes costly. Short flight time divides one inspection route into multiple sorties, increasing setup time, route gaps, and the number of takeoff and landing cycles.

IPET Design Response

I Series is designed for efficient multirotor operation at practical hover and route loads. In demonstrated aircraft configurations, I7 supported more than 120 minutes of flight and I8 more than 300 minutes, providing engineering references for platforms where continuous route coverage matters.

Surveying Mapping and Wide-Area Data Capture

Mission Challenge

Mapping quality depends on stable flight lines, image overlap, speed control, and consistent power output. Limited endurance forces route splitting, additional takeoffs, more landing risk, and extra dataset stitching.

IPET Design Response

I Series supports multirotor mapping platforms that require efficient hover and low-speed route work, while IV Series supports VTOL and fixed-wing aircraft that prioritize efficient cruise across larger areas. Matching the propulsion architecture to the flight mode helps reduce route interruptions and field operations.

I Series: Multirotor Endurance
IV Series: VTOL Cruise Efficiency
Fewer: Route Interruptions

Security Patrol and Persistent Observation

Mission Challenge

Perimeter patrol, public-safety monitoring, and persistent observation require the aircraft to stay airborne at moderate power for extended periods. Frequent battery changes create surveillance gaps, repeated launch cycles, and higher ground-crew workload.

IPET Design Response

IPET helps match propulsion to hover load, patrol speed, payload, and required on-station time. I7 and I8 support endurance-focused multirotors, while IV7 supports VTOL aircraft that transition to efficient cruise for longer patrol routes.

Longer: On-Station Time
Fewer: Battery Changes

Select Long-Endurance Propulsion by Platform and MTOW

Use this matrix to narrow the starting configuration by aircraft type, MTOW, voltage, and propeller size. Final selection should be checked against actual hover or cruise load, payload, airframe clearance, battery capacity, altitude, thermal margin, target flight time, and the relevant bench test data.
