With first production engine deliveries expected later in 2025, the GTF Advantage will provide 4-8% more takeoff thrust, enabling higher payload and longer range, unlocking new destinations for airlines. In the high-pressure turbine (HPT), the enhancements include an advanced airfoil design with improved coatings.

The term 'angle of attack' is defined as the angle between the airplane's longitudinal axis and that of the air striking the airfoil. Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface. The four forces acting on an airplane in flight are lift, weight, thrust, and drag.

D-558-2 Skyrocket take off using JATO assist in 1949 NACA engineers improved the rockets performance by adding nozzle extensions to its combustion chambers, reducing exhaust interference with the rudders and increasing thrust at altitude. Both aircraft display early examples of swept-wing airfoils.

Depending on design, airfoils used in general aviation, stall at angles of attack between 16 to 18 degrees. This is because the vertical component of thrust reduces the wing loading, and the propeller slipstream tends to maintain airflow over the center sections of the wings.

The aircraft also participated in studies involving low-altitude flight with asymmetric engine thrust. These glove modifications served to smooth the wing surface and alter the airfoil to achieve specific pressure distributions.

Powered-lift: Heavier-than-air aircraft capable of vertical takeoff, vertical landing, and low speed flight that depends principally on engine-driven lift devices or engine thrust for lift during these flight regimes and on nonrotating airfoil(s) for lift during horizontal flight.

An angle of attack (AOA) indicator can determine the aerodynamic health of the airfoil (wing). More simply, an AOA indicator displays the margin between the current AOA of the airfoil, and the AOA at which the airfoil will stall (critical AOA), providing the pilot with a visual and sometimes audible indication.
