S7 Tango APD-520 Engine: A ‘Russian’ Power plant or Belgian UL520iS Copy?

The Tango aircraft is Russia’s bold attempt at aviation independence—but does it truly break free from Western tech? Developed by Spectra Aircraft under the S7 Group, this four-seat, composite-built plane is undergoing flight tests in 2025, targeting private owners and flight schools. However, its "Russian" APD-520 engine is a near-replica of Belgium’s ULPower UL520i, raising questions about true localization. Despite claims of a domestic breakthrough, serial production is delayed until at least 2027 due to ongoing engine certification. Why did Russia choose a Belgian engine after the 2022 sanctions? The Tango’s prototype first flew with the imported UL520i in 2024—a puzzling choice given geopolitical tensions. While the APD-520 now powers test models, its specs (200 hp, 5.2 L displacement) mirror the Belgian original. Is this reverse engineering or licensed production? Meanwhile, the Tango boasts a 1,100 km range, 245 km/h top speed, and short takeoff capability, making it ideal for training. However, with competitors such as the Yak-152 continuing to depend on foreign engines, is it feasible for Russia's aviation sector to operate independently? The stakes are high for Russia’s aerospace future. The Tango represents a test of whether Moscow can replace Western tech under sanctions. While its composite airframe and modern avionics impress, the engine saga reveals lingering dependencies. Will the Tango become a staple of Russian flight schools or join a list of delayed projects? #TangoAircraft #RussianAviation #AviationIndependence #SpectraAircraft #GeneralAviation #FlightTraining #APD520 #SanctionsTech #AerospaceNews #AviationGeek Be a Member for exclusive privileges -    / @altitudeaddicts   Twitter : https://x.com/AltitudeAddicts Website: https://www.altitudeaddicts.com
