The secret of the PW1000G engine is not the Fan Drive Gear System (FDGS). It’s the game-changing geared turbofan (GTF) architecture enabled by the FDGS, and supported by a family of engines at the highest level of technology readiness. We don’t have to compromise on noise, maintenance, and installation, to get a big improvement in fuel burn. We get much higher efficiency out of every module in the engine.
The most efficient fan in its class:
A large, light-weight fan moves well over 90% of air around the core, delivering a very quiet engine with very low fuel burn.
The most efficient compressor and turbine in their class:
A compact, high-speed low-pressure system accomplishes the same work in fewer stages. That means fewer airfoils, fewer life-limited parts, and ultimately lower maintenance costs.
A really cool core:
The supercharged low-pressure system allows the advanced PurePower engine core – optimized for high-cycle durability – to run cooler than the competition, with fewer stages, and without expensive, exotic materials. That means longer time on wing and lower maintenance costs.
Unlike traditional engine designs, the geared architecture is just getting started. It is the solution for this decade—and the next one. That means the technology you buy today, P&W will build upon tomorrow. And that's the best investment you could make.

What's in a Name?
How we name our engines.
The numbering scheme for each PW1000G engine model follows the same historical Pratt & Whitney pattern; the first number represents the generation - in this case, 1 or 1,000. The second number denotes the customer: 1 for Airbus,
2 for Mitsubishi, 4 for Irkut, and 5 for Bombardier. The last two numbers indicate the thrust class: 24 for 24,000 pounds of thrust, and so forth. And finally, the "G" stands for a geared turbofan engine. Below, the full PW1000G engine
product table is listed in order of thrust.
