History
According to the Pratt & Whitney project, the engine was supposed to be simple in design, which significantly reduced maintenance costs and made it smaller in weight and economical in fuel consumption. Nevertheless, tests showed that early developments with a 5-stage high-pressure compressor did not meet the specified cost-effectiveness requirements. As a result, many of the engine's customers changed their choice to CFM International CFM56 -5. Some customers chose early airbuses. To solve the problem, a 6-stage high-pressure compressor developed by MTU Aero Engines was used to achieve the promised performance. So, the production of high-pressure compressors and low-pressure turbines began the German company.
The engine made its first successful flight lasting 1 hour 20 minutes on a test plane on August 21, 2000 at the Plattsburgh International Airport. Engine assembly is carried out by MTU Aero Engines in the city of Hanover .
On August 15, 2005, LAN Airlines confirmed an order for 34 PW-6000 engines to equip 15 Airbus A318 aircraft (30 for installation and 4 spare). In addition, LAN signed an agreement with Pratt and Whitney to equip an additional 25 aircraft with engines, and if these aircraft appear on the LAN, an order for 56 engines will be confirmed (50 installation and 6 spare).
Prior to this, LAN's Airbus A318 aircraft were powered by CFM56-5 engines, and as of December 2005, out of 84 CFM56-5 engines, only 28 were operating.
