Product Overview
This 70N micro turbojet UAV engine is a compact lightweight liquid-fuel drone gasoline engine specially developed for small-size civilian unmanned aerial vehicles and high-end RC jet aircraft. As a miniaturized jet-type UAV gasoline engine, it outputs stable 7kg static thrust while only weighing 850g, perfectly matching compact airframes with limited internal installation space.
Different from heavy piston UAV engines, this turbojet power unit eliminates complicated manual startup equipment and adopts full-automatic ECU fuel ignition control. It supports multiple civilian fuel types including aviation kerosene and diesel, providing flexible fuel selection for global commercial operators. Its ultra-compact dimension of 90mm diameter × 230mm length greatly reduces dead weight of small UAVs and reserves more space for aerial survey sensors, photography equipment and other civilian payloads.
All design, testing and production standards are oriented purely to non-military commercial scenarios, serving aerial mapping, agricultural patrol, educational aerospace research and recreational high-speed RC aviation projects.

Detailed Structural & Technical Features
All-in-One Automatic ECU Ignition System
This UAV gasoline engine integrates a dedicated digital ECU control unit to realize fully automatic startup without external auxiliary power equipment. The ECU dynamically adjusts fuel injection volume, ignition timing and air mixing ratio according to real-time altitude, ambient temperature and throttle signal, ensuring reliable cold start under low-temperature and high-altitude conditions. Short ground preparation time improves the operation efficiency of civilian drone teams.
Leak-Proof Sealing & Low-Consumption Lubrication System
The proprietary composite sealing ring structure eliminates lubricant leakage at low startup RPM, a common defect of ordinary small turbojet UAV engines. The optimized bearing circulation lubrication scheme only requires a 2% oil mixing ratio for repeated long-distance flights, cutting lubricant procurement costs and reducing carbon deposit accumulation inside the combustion chamber. For single short test flights, operators can directly use pure fuel without adding lubricating oil.
High-Efficiency Fuel Atomization & Full Combustion Assembly
Custom micro fuel mixing nozzle enhances fuel atomization uniformity under variable fuel pressure. Complete fuel combustion reduces exhaust residues and lowers hourly fuel cost, complying with global civilian aviation emission standards. Stable atomization performance avoids flameout risks during rapid throttle rise and fall for high-speed small UAV flight.
Miniature Anti-Vibration Compact Body Frame
All connecting fasteners adopt anti-loosening vibration-resistant locking structure, paired with anti-corrosion salt-fog coating on the engine outer shell. The ultra-small streamlined layout reduces flight wind resistance and saves valuable cabin space for civilian payload devices. Standard unified mounting lugs support direct installation for most mainstream small civilian fixed-wing airframes without customized mechanical modification.
Low-Temperature Cooling & Ultra-Balanced Rotor Assembly
Independent surrounding cooling passages wrap the bearing and rotor core components, maintaining much lower operating temperature than traditional micro jet engines and prolonging overhaul intervals. Precision high-speed dynamic balancing processing offsets rotor unbalance vibration under 155000 RPM extreme rotation speed, minimizing vibration interference to onboard aerial survey cameras and data transmission modules.

Factory Strict Quality Control Process
Every finished 70N micro turbojet UAV gasoline engine passes 5 full inspection links before factory delivery:
- Raw material incoming inspection: High-temperature alloy rotor, sealing parts, ECU electronic control module dimensional and material composition testing.
- Ultra-high-speed rotor dynamic balancing calibration and vibration value detection.
- Continuous full-throttle bench test for 2 hours, real-time recording thrust, RPM, fuel consumption and exhaust temperature data.
- Sealing leak test and high-altitude low-temperature cold start simulation test.
- Final appearance anti-rust protection and complete packaging inspection.
Each drone gasoline engine is assigned an exclusive unique serial number, and all bench test data are permanently archived to provide traceable quality guarantee for global civilian UAV integrators and hobby dealers.
Frequently Asked Questions
FAQ 1: What fuel types are allowed for this 70N micro turbojet UAV engine? Are there any forbidden fuel types?
Answer: This UAV gasoline engine supports civilian aviation kerosene, standard diesel and common civilian unleaded gasoline. Any fuel with ethanol content higher than 10% is strictly prohibited. Ethanol will generate massive carbon deposits inside the combustion chamber and block the precision atomization nozzle, causing permanent power attenuation and engine failure. Please filter fuel completely before adding it to the tank, and follow the 2% lubricant mixing ratio for repeated long-duration flight missions.
FAQ 2: Can this small turbojet drone gasoline engine be matched with hybrid VTOL civilian UAVs? What regular maintenance should users perform?
Answer: This UAV engine is primarily optimized for compact small fixed-wing civilian UAVs. It can be installed on mini hybrid VTOL platforms only after consulting our technical team for airframe structural reinforcement suggestions. Standard maintenance cycle: Complete disassembly inspection and replace sealing rings every 50 flight hours; simply clean the fuel nozzle and cooling channel every 10 flight hours to maintain stable 70N thrust output and extend engine service life.
