For light aircraft Diamond Aircraft, which UZGA produced under license
The Ural Civil Aviation Plant has announced a tender for the supply of two engines E4-A and E4-C with sets of spare parts. The plant is ready to pay up to 232 million rubles for the supply of engines.
Apparently, we are talking about Austro Engine E4 motors. There are two motors in this line: AE300 and AE330. The second is slightly more powerful (180 hp at takeoff versus 168 hp for the AE300). Both run on kerosene and spin the propeller at speeds of up to 2300 rpm.
UZGA plans to install engines on light aircraft Diamond Star and Diamond Twin Star — both are used for training. UZGA produced these aircraft under license from Diamond Aircraft.
