The mainstay of the United Engine Corporation's (UEC) commercial aircraft engine development programme is the development of the 12,500-15,600-kgf PD-14 new-generation turbofan engine - the first one in the advanced 9-18 tonne engine family being developed by a large team of UEC's subsidiaries led by Aviadvigatel JSC. The PD-14 is a two-shaft separateflow engine with the gearless fan drive. All engines of the family have a common core with the eightstage high-pressure compressor, low-emission annular combustor and two-stage high-pressure compressor. The baseline PD-14 will be equipped with a 1,900-mm single-stage fan retaining the diameter of the fan used in the PS-90A engine, a three-stage low-pressure compressor and a sixstage low-pressure turbine.

The kickoff of the flight tests of the advanced Kamov Ka-62 medium multirole helicopter will become an event of the year. The helicopter is being developed by Kamov and manufactured by the Arsenyevbased Progress aircraft company named after N.I. Sazykin (both companies are Russian Helicopters subsidiaries).
