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

Aviation Bussiness News

In the high-pressure turbine (HPT), the enhancements include an advanced airfoil design with improved coatings. It is fundamentally more durable, with increased airflow in the core to lower operating temperatures and a state-of-the-art hot section to increase time on wing.

Vintage Aviation News

Davis, who had developed a new wing, whose airfoil had a lower drag co-efficiency than other wing designs of the time, and which had already been used on the company’s Model 31/XP4Y Corregidor flying boat. The company had hired a freelance aeronautical engineer, David R.

Quiz: Basic Aircraft Aerodynamics

Flight Training Central

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. Aircraft power, pitch, bank, and trim. airplane's center line and the relative wind.

Sensenich Introduces New Cessna 172 Propeller

Plane and Pilot

A more modern airfoil helps performance as well. According to the company, the prop at a median pitch setting yielded improved take-off and climb performance with better cruise speeds and fuel flows. Moreover, the new prop and carbon-fiber spinner combination results in a 13-pound reduction over the standard fixed-pitch metal prop.

What Is Bernoulli’s Principle? A Simple Guide for Pilots

Pilot Institute

Airfoils use this principle, with faster airflow over the top creating lower pressure. If lift were entirely due to Bernoulli, a symmetric airfoil (one with equal curvature on top and bottom) wouldnt generate lift – yet it does when given the right angle of attack. In reality, the wing also uses Newtons third law to create lift.

Flight Test Files: Convair XF-92A Dart

Vintage Aviation News

The delta wing’s large area (425 square feet), thin airfoil cross section, low weight, and structural strength made a great combination for a supersonic aircraft. It was built as a test bed for a proposed interceptor that never materialized. The XF-92A was then used to test the delta-wing concept.

Today in Aviation History: First Flight of the Stipa-Caproni

Vintage Aviation News

During these years, he concluded that the inner surface of the venturi tube needed an airfoil shape to achieve the greatest efficiency. The duct, as predicted by Stipa, had a profile similar to that of the airfoil, with a fairly small rudder and elevators mounted on the trailing edge of the duct. The Stipa-Caproni in flight.
