Pratt & Whitney Launches HPC to The Cloud To Push Jet Engine Design

The commercial aviation industry emits million metric tons of carbon dioxide each year. While that represents only about 2 percent of global carbon emissions, there is evidence that the greenhouse gases in jet fuel have a larger effect on the atmosphere because they are released at high altitude. Efforts to introduce biofuels to power jet engines have so far fallen short of their targets, and many in the industry believe the pathway to cleaner jets is through advances in engine technology rather than cleaner fuels. Competitor CFM International, meanwhile, has introduced its own advanced engine, called the Leap , which could achieve similar improvements without such a radical break from existing technology. Turbofan engines use a large-diameter fan to pass air through the engine and have dominated commercial aircraft since the s. Adding the gearbox, however, makes the engines heavier and increases aerodynamic drag.

All commercial aircraft designed in the last 40 years other than aircraft with fewer than a dozen passengers are powered by gas turbine engines, either turbofan or turboprop. Thus, any discussion of reducing carbon emissions from commercial aircraft will need to consider the potential for improvement of gas turbine engines. To that end, this chapter will delineate the current state of the art of aircraft engines, discuss the potential for and constraints on gas turbine improvement over the next three decades, and suggest research directions to achieve such improvement. Unless otherwise noted, the discussion in this chapter refers to gas turbine engines for large commercial aircraft, as discussed in Chapter 1. For this discussion, engine refers to the device that converts the energy in fuel into shaft power and the shaft power into propulsive power.

  1. While airlines would appreciate better fuel efficiency, the promise of quieter flights for passengers and for people on the ground could also allow airlines to land more planes at airports with noise restrictions.
