Product Brief Introduction
The SW220Pro micro turbojet UAV gasoline engine is a next‑generation professional‑grade miniature gas‑turbine power solution engineered for medium‑large civilian unmanned aerial vehicles and high‑end recreational RC‑jet platforms. Upgraded from classic B‑series products, this UAV gasoline engine adopts brand‑new V4 intelligent ECU system together with optimized brushless starter assembly and enhanced self‑priming fuel system, bringing faster startup speed, richer diagnostic functions and wider environmental adaptability compared with earlier‑generation models.
With compact integrated mechanical framework, this drone gasoline engine measures 115.5 mm outer diameter, 278.5 mm overall length, with main‑body net dry weight of merely 1800 g. The supporting V4 ECU weighs 353 g. The whole set can work stably within ‑40℃ ~ +50℃ ambient temperature range and takes standard aviation kerosene as fuel with a 3%‑5% turbine lubricant mixing ratio, while peak fuel consumption is controlled under 620 g/min under full‑thrust operating condition.
All R&D, manufacturing and bench‑test specifications are strictly confined to non‑military civilian commercial, educational and hobby‑aviation scenarios. The complete supporting accessory kit is shipped alongside the main engine unit to shorten assembly and commissioning cycles for global buyers.

Core Independent Technical Highlights
V4‑Generation Intelligent ECU Control Unit
This UAV gasoline engine is equipped with upgraded V4‑generation digital ECU, which can read multi‑channel sensor data and precisely regulate fuel delivery volume, ignition timing and brushless starter operation. It supports rapid startup procedure, completing whole startup workflow within 30 seconds for compatible high‑speed civilian power platforms.
The built‑in fault‑diagnosis module records engine runtime error information and stores fault codes inside onboard memory chip; visual alarms will be triggered once abnormal states occur, greatly simplifying post‑incident inspection and maintenance work for technicians. Besides, the ECU dynamically monitors ambient atmospheric pressure and temperature, automatically adjusting operating parameters to adapt to extremely cold or hot field conditions. Firmware upgrade is supported to modify engine performance parameters according to personalized civilian mission requirements. It can also send control instructions and collect feedback data for TCU execution units.
High‑Performance Brushless Starter Motor
The proprietary brushless starting motor matched for this drone gasoline engine removes carbon‑brush components, getting rid of electric‑spark interference generated by traditional brushed motors, which effectively protects onboard wireless remote‑control and telemetry equipment. It delivers broad speed‑regulating range, low steady‑state speed error, high energy efficiency and low power consumption; its power consumption is merely one‑third of comparable brushed starter motors.
Compact lightweight physical dimensions bring high installation flexibility for airframe designers. Without easily‑worn brush parts, the whole starter assembly achieves higher mechanical reliability, smoother running performance and lower operational noise under frequent cold‑start cycles.
Enhanced Self‑Priming Fuel Supply System
The supporting fuel system is fully compatible with SWIWIN mainstream civilian turbojet series including SW190B, SW220B and SW300B. Featuring compact miniaturized layout, it occupies very limited cabin installation space. The pump unit delivers powerful self‑priming performance and maintains stable fuel suction under high‑speed, low‑speed or manual priming conditions.
It can transport medium‑high‑viscosity aviation lubricants and kerosene reliably. The whole fuel assembly runs stably across ‑40℃ to +50℃ wide temperature range with even flow and steady oil pressure. The structure brings low failure rate, convenient disassembly and low‑cost spare‑part replacement for long‑term commercial operation.
High‑Temperature‑Resistant Integrated Turbine Main Body
Turbine rotor, combustion chamber and exhaust nozzle of this UAV gasoline engine are all cast from premium aviation superalloy. These components continuously tolerate 750 ℃ exhaust temperature under full‑load working conditions without structural deformation or power decay. Streamlined outer casing cuts aerodynamic drag during flight. Symmetric standardized mounting lugs are pre‑reserved to fit most mainstream medium‑large‑size civilian fixed‑wing UAV and RC‑jet airframes without custom mechanical modification.
Civilian Commercial Application Scenarios

Factory R&D & Strict Quality Inspection Flow
The manufacturer maintains complete in‑house micro‑turbine R&D laboratories, CNC intelligent manufacturing workshops and full‑function turbine bench‑test facilities. Every finished SW220Pro UAV gasoline engine must complete six critical inspection procedures before factory dispatch:
- Incoming raw‑material verification: material‑composition analysis plus dimensional calibration for high‑temperature‑alloy rotor, V4‑ECU chip, fuel‑pump hardware and all sealing components.
- Ultra‑high‑speed rotor dynamic‑balancing calibration and real‑time vibration‑magnitude detection.
- Three‑hour uninterrupted full‑load bench test; thrust value, rotational speed, exhaust temperature and fuel‑consumption metrics are logged synchronously.
- Wide‑range temperature‑simulation cold‑start testing for startup‑reliability validation under ‑40℃ ~ +50℃ harsh environmental conditions.
- Full‑kit accessory matching inspection plus functional verification covering wiring harnesses, fuel‑system parts, V4‑ECU and GSU data‑display hardware.
- Finished‑unit anti‑rust protection, anti‑static handling and final packaging quality audit.
Each drone gasoline engine receives a unique independent serial number. All bench‑test logs and manufacturing records are permanently archived to deliver traceable quality assurance for global civilian UAV integrators and resellers.
Frequently Asked Questions
FAQ 1 What fuel and lubrication mixing ratio should I use for SW220Pro UAV gasoline engine? What advantages does the upgraded V4 ECU bring compared with V3 version?
Answer: This UAV gasoline engine must utilize pure aviation kerosene blended with dedicated turbine lubricating oil at a mixing ratio of 3%‑5%. Any ethanol‑containing fuel is strictly forbidden. Ethanol will generate heavy carbon accumulation inside combustion chambers, clog fuel‑pump pipelines and inflict permanent damage upon high‑temperature turbine rotors. Please clean the fuel filter before every refueling event to stop particulate matter from obstructing fuel circuits. Perform full‑disassembly maintenance strictly complying with the 25‑flight‑hour service cycle.
Compared with V3 ECU, the V4 version adds complete fault‑code recording, ambient‑environment monitoring and firmware‑upgrade functions. It supports faster 30‑second‑level rapid startup for matched high‑speed platforms and provides richer data feedback for ground‑station monitoring.
FAQ 2 Can the V4 ECU of SW220Pro match third‑party autopilot hardware? How should operators handle engine fault‑code alarms triggered during operation?
Answer: The communication interface of V4 ECU works with mainstream civilian‑grade industrial autopilot products available on global markets; matching communication‑protocol documents are supplied free‑of‑charge. When fault‑code alarms pop‑up on GSU display terminal, please record the exact fault code number first. Then shut down the engine safely and check fuel circuit, wiring harness and sensor connections according to official troubleshooting guidelines. If you cannot locate the root cause, send the fault‑code record to our technical team for remote diagnostic support. Do not repeatedly force startup under alarm status to avoid secondary component damage.
