Pratt & Whitney’s GTF Advantage engine achieves FAA type certification

Aviation Bussiness News

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 Role of Newton’s Third Law in Aviation

Pilot Institute

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.

Nothing Small About It

Plane and Pilot

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
