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.

Use of Reflex Airfoils Ever notice how many tailless aircraft have wings that curve at the trailing edge? This type of design is a reflex airfoil. The reflexed shape of the airfoil usually causes a positive (nose-up) pitching moment coefficient at its aerodynamic center. Flying wings dont have tails or elevators.

Developments in aircraft design and engine technology have allowed us to fly farther, faster, and carry more payload. They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. If we understand it well enough, we can harness this phenomenon to help us even defy gravity.

Another tradeoff that you need to juggle is payload vs range. For the F-111 and many other similar aircraft, the range decreases as the payload gets heavier. According to Robert Gregg, Boeing’s chief aerodynamicist , supercritical airfoils help delay shock waves by managing how pressure waves behave at high speeds.

The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance. This is a Riblett-airfoil airplane with a slow stall speed (we got it down to 42 knots IAS and it didn’t stall) and a cruise speed of 120 knots. lb/sq ft Power loading 10.32
