The Kuznetsov NK-12 is a Soviet turboprop engine of the 1950s, designed by the Kuznetsov design bureau. The NK-12 drives two large four-bladed contra-rotating propellers, 5.6 m (18 ft) diameter (NK-12MA), and 6.2 m (20 ft) diameter (NK-12MV). It is the most powerful turboprop engine to enter service.
The Airbus A400M is powered by four Europrop TP400 engines, which are the second most powerful turboprop engines ever produced, after the 11 MW (15,000 hp) Kuznetsov NK-12. In 2017, the most widespread turboprop airliners in service were the ATR 42 / 72 (950 aircraft), Bombardier Q400 (506), De Havilland Canada Dash 8 -100/200/300 (374 ...
However, because of mechanical and aerodynamic problems that Lockheed Martin encountered on its C-130J Super Hercules upgrade, which used new engines and propellers that had half the planned output of the TP400, Airbus retained the option to select the engine configuration and the propeller for itself. The TP400 development schedule, which was ...
The first engine run with propeller took place in 2006, with the first flight of the TP400 aboard a testbed taking place in 2008. The first flight of the A400M took place in 2009. [10] Two years later the TP400 engine received EASA certification. [11] The first engines were delivered in 2012. The French Air Force began using the A400M in 2013. [4]
The two are in one large engine casing with the fan (propeller) at the front and the jet engine behind, with both turbine exhaust and fan-driven air exiting the rear of the engine casing. Turboprop engines are similar, but use an external propeller rather than an internal fan (propeller) inside an engine casing. The hot exhaust gas from a ...
The engine had a split-compressor (also known as "two-spool") design. [6] Intended for use on the Douglas C-132 aircraft, the XT57 turboprop used a Hamilton Standard Model B48P6A propeller with a diameter of 20 feet (6.1 meters), which was the largest diameter propeller to be used in flight at the time.

The higher thrust GE90-110B1 and -115B engines, in combination with the second-generation 777 variants -200LR and -300ER, were primary reasons for 777 sales being greater than those of the rival A330/340 series. [19] Using two engines produces a typical operating cost advantage of around 8–9% for the -300ER over the A340-600. [20]
