This is about the same size as a motorcycle engine. I'm assuming of course that the 550 means 550 cubic centimeters which could mean something like a 500 or a 550 motorcycle engine. However, this likely has a different design simply because it only has to land a little over 1000 miles in flying anytime this thing is started up to fly. So, likely there have been many modifications to this engine because the engine doesn't have to last years and years but only as long as it takes to reach it's target of 1000 miles usually or less.
begin quote:
The MD550 is a 50-horsepower,
four-cylinder, two-stroke air-cooled piston engine primarily known for
powering the HESA Shahed-136 "suicide" drone. Often identified as a Chinese-produced or Iranian-made (Mado) clone of the German Limbach L550E engine, it is designed for low-cost, long-range unmanned aerial vehicles (UAVs).
Key Characteristics and Technical Specifications
- Engine Type: Four-cylinder, horizontally opposed, two-stroke gasoline engine.
- Power Output: Approximately 37 kW (50 hp) at 7,500 rpm.
- Displacement: 548 cm³ (33.4 cu in).
- Weight:Approximately 16 kg (35 lb).
- Fuel/Oil Mixture: 90 RON octane unleaded petrol or 100 LL Avgas with a 50:1 (synthetic) or 25:1 (mineral) oil ratio.
- Ignition: Solid-state magneto ignition.
- Application: Used extensively in the Shahed-136 to achieve an estimated 2,500 km range.
Production and Variants
- Origin: While based on the 1980s German Limbach L550 design, the engines utilized in modern drones are often Iranian (Mado brand) or Chinese counterfeits.
- Modifications: Drone variants frequently include an integrated alternator/generator to power onboard avionics.
- Simplified Models: In 2024, Russian-produced versions were simplified by removing components like the starter and flywheel to reduce costs, leading to lower reliability and shorter operational life.
- Reliability: Reports indicate that restoring a single functional MD550 often requires components from at least three different engines.
