Compact Small-Scale Gas Turbine Engine MT-20 (19 kgf) MT-20 is a compact small-scale gas turbine engine (turbojet engine) manufactured by JSC “Motornaya Lavka”, with a thrust of 19 kgf, designed for: • high-speed fixed-wing UAVs; • jet-powered unmanned platforms for special missions; • experimental and relatively small-class jet aircraft; • scientific and test bench jet installations; • target and test aerial drones. The engine is intended for use in lightweight high-speed platforms where high thrust is required with minimal size and weight. Advantages: • domestically produced small-class turbojet engine; • solution for high-speed UAVs; • low weight and compact geometry; • alternative to imported micro turbojet engines in the up-to-20 kg class; • local service support; Technical Specifications (TDS) Main parameters: • Nominal thrust: 19 kgf • Engine diameter: 109.5 mm • Length: 260 mm • Engine weight: 1500 g • ECU weight: at least 60 g • Total weight (with accessories): 1920 g • RPM range: 38,000 – 120,000 rpm • Nominal exhaust temperature: 750 °C • Service life: 20 h Fuel system: • Fuel: aviation kerosene • Oil (fuel additive): 3–5% • Fuel consumption at maximum RPM: 550 g/min Electrical system and start: • Power supply: 3S LiPo battery • Start method: electronic start “single-button” (in accordance with the operating manual) Operating parameters: • Operating temperature range: −40 °C … +50 °C Design and operational features: • Compact axial configuration • High thrust-to-weight ratio (~12.7 kgf/kg) • Electronic Control Unit (ECU) with integrated start system • Automatic adaptation to extended temperature operating conditions • Suitable for use in light and medium-class UAVs Other: • OKPD 2 code: “30/30/12/110” • HS code: “8411 /11 /000 /9” — turbojet engines Foreign analogs (lower cost segment): • JetCat P20-SX (~20 N) — smaller class • JetCat P60 (~60 N) — higher class • AMT (Netherlands) — 18–22 kg segment Asian: • Swiwin SW20/SW30 series • KingTech K20/K25 • Xicoy class 20N–30N
