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. The four forces acting on an airplane in flight are lift, weight, thrust, and drag.

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

Vintage Aviation News

The unique cylindrical design of the fuselage allowed for a streamlined profile and reduced drag, increasing the overall efficiency. During these years, he concluded that the inner surface of the venturi tube needed an airfoil shape to achieve the greatest efficiency. The Stipa-Caproni in flight.

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.

The No Longer Invisible Angle of Attack: AOA Indicators

Learn to Fly

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.

Air Facts

The Four Forces of Flight (Lift, Thrust, Drag & Gravity) obey Newton’s Three Laws of Motion. irplane controls work per the Lever Principle, and a wing’s airfoil shape increases lift via the Bernouilli Principle and Coanda Effect. Like Moses and the Ten Commandments, aviation is limited by 10 laws of physics and chemistry.

One of the most revolutionary was the “area rule,” a concept that helped aircraft designers avoid the disruption in airflow and resulting drag caused by the attachment of the wings to the fuselage. The resulting “supercritical airfoil” shape, when integrated with the aircraft wing, significantly improves the aircraft’s cruise efficiency.

And ice doesn’t just make things slippery, it messes with the airflow over the wings, cuts down on lift, and ramps up drag. Remember that wings, propeller blades, and tail surfaces are airfoil-shaped. Ice build-up on the airframe changes the airflow pattern around these airfoils.
