Product Overview
LT400 heavy-duty micro turbojet engine is a high-power civil propulsion solution independently developed for large industrial unmanned aircraft, heavy-load fixed-wing drones and giant aeromodelling platforms, acting as a premium high-thrust UAV engine and drone gasoline engine alternative for heavy civil flight equipment.
Our factory specializes in independent R&D and mass manufacturing of miniature turbojet power units and gasoline-electric hybrid propulsion systems. We commit to supplying eco-friendly, energy-saving, intelligent, high-efficiency and cost-effective power solutions for global commercial UAV manufacturers, aeromodelling brands and university aerospace labs.
Unlike small-size light turbojet models such as LT20, LT400 delivers peak 420N stable thrust to match large airframes with heavy survey, spraying and monitoring payloads. It breaks the single-fuel limitation of most traditional UAV gasoline engine, supporting multi-fuel supply to fit diverse global operation regions. All hot-end core components are forged with aerospace-grade heat-resistant alloy materials, passing thousands of hours of continuous aging, vibration and temperature cycle testing to guarantee stable all-day operation for industrial UAV fleets.

In-Depth Performance Feature Analysis
Stable High-Thrust Output & Linear Throttle Response
Equipped with optimized compression and combustion flow channel design, this UAV engine maintains steady 420N thrust under full-load operation. Its linear thrust output at low RPM solves the insufficient takeoff power problem of ordinary drone gasoline engine, perfectly supporting heavy-payload UAV rapid ascent and high-speed cruise missions like large-area aerial mapping and farm plant protection.
Leak-Proof Sealing & Low-Consumption Lubrication System
The unique multi-layer sealing structure completely solves oil dripping issues at low startup RPM. Matching proprietary lubrication formula slashes engine oil usage, lowering long-term operating costs for commercial UAV operators and avoiding extra maintenance caused by oil leakage pollution.
Outstanding Environmental Adaptability & Anti-Damage Performance
Reinforced anti-vibration mounting structure with salt-spray and overload resistance allows stable operation in coastal humid areas, high-temperature open farmlands and cold mountain zones. Strong signal anti-interference design ensures uninterrupted communication between the UAV flight controller and this turbine power unit.
Extended Service Life via Exclusive Cooling & Balancing Tech
Self-developed active cooling system reduces rotor and bearing operating temperature; ultra-precise rotor dynamic balance craft cuts internal vibration loss. Combined, these technologies greatly prolong the continuous flight service cycle of this UAV gasoline engine and lower component replacement frequency.
High Consistency & Easy Daily Maintenance
Standardized mass production ensures identical performance of each engine unit, avoiding inconsistent thrust output across multi-drone fleets. Modular split layout allows users to disassemble, inspect and replace fuel nozzles, ignition electrodes and filter elements without professional dedicated tools, simplifying routine maintenance workflows.
