The TF-TJ2000A is a micro turbojet from the Chinese firm Telefly, sold on Made-in-China as a model-aircraft engine. Telefly’s listing gives 200 kgf of thrust from an engine weighing 29.24 kg, and notes that its products are “solely for civilian use”.
HUR War & Sanctions found one, serial number 0000000060, in a recovered Geran-5. Euromaidan Press, reporting HUR’s Geran-4 release, says the same engine is fitted to some Geran-4s alongside the older LX-WP-160. In a teardown filmed by Radio Svoboda’s Schemes, a specialist identified a “TJ-2000” from a Geran and said the Chinese maker rates it for 30 hours of running. In October 2026 HUR said the Geran-4’s Telefly engine had been replaced by a Russian-made equivalent produced at Alabuga (Interfax-Ukraine).
