GP7200 Engines Soar in the Hot Temperatures of the Gulf
All things being equal, does hot weather make an aircraft engine’s job easier or harder during takeoff? What about humid weather? Does humid air make for longer or shorter takeoffs?
It turns out that both high temperatures and high humidity require an engine to work harder during takeoff, since they reduce an engine’s thrust. That’s why the fast-growing airlines of the Gulf region, where the weather is both hot and humid for a large part of the year, are always looking for engines that deliver the best performance in these conditions.
It’s no surprise, then, that like two of its peer airlines in the Middle East, Abu Dhabi’s Etihad Airways has selected the Engine Alliance GP7200 to power its fleets of Airbus A380 aircraft. Airbus took delivery of the eighth GP7200 engine to power the first two Etihad Airways A380 aircraft. Those planes are scheduled for delivery to Etihad in December.
Since going into service in the Middle East in 2008, these engines have shown they can perform extremely well in the region’s hot and sandy environments. This is in part due to the continual enhancements that incorporate GE’s experience operating the GE90 and GEnx engines in the Middle East. GE has brought the lessons from those engines into the steady stream of enhancements to the GP7200. In all, the Engine Alliance has implemented three fuel-burn improvements to the engine.
Airlines operating GP7200 enjoy the quietest, most reliable and most fuel-efficient powerplant for the Airbus A380. The GP7200 engine has delivered an average of 99.9% departure reliability and provided customers with a fuel savings advantage of up to $1 million per aircraft per year. The Engine Alliance is a 50-50 joint venture between GE and Pratt & Whitney.
