The exhaust ports of a NK-12 in an outboard nacelle on a Tu-95. 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).
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 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 ...
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]
One XT57 (PT5), a turboprop development of the J57, was installed in the nose of a JC-124C (BuNo 52-1069), and tested in 1956. [3] [4]Rated at 15,000 shaft horsepower (11,000 kW), the XT57 was the most powerful turboprop engine in existence at the time, [5] and it remains the most powerful turboprop ever built in the United States.

The most powerful turboprop engines to enter service on any aircraft, the Kuznetsov NK-12MV, each driving two AV-60H, contra-rotating, four-bladed, reversible-pitch propellers. Lower deck galleys. A dumbwaiter connected the galley to the upper deck; originally, a member of the crew was a chef. Lower deck aircrew rest area.
Exceptional windstorms that could leave some Houston residents without power for weeks were a once-in-a-generation event and the damage left in their wake is comparable to that caused by a ...
In most aircraft installations the PT6 is mounted so that the intake end of the engine is towards the rear of the aircraft, leading to it being known by many as the "back-to-front" engine. [4] This places the power section at the front of the nacelle, where it can drive the propeller directly without the need for a long shaft.
