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.

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.

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.

McChord Air Museum Restoring World War II TG-4 Glider

Vintage Aviation News

It will be coupled with a wind tunnel and a few different types of airfoils to demonstrate the effect of airflow at different angles. The airframe itself never flew with the military – being put into storage immediately after being built – but was eventually sold to civilians.

There’s Something Essential in the Bank

Flying Magazine

The majority of the lift generated by an unstalled airfoil is always concentrated near the front, and moving a trailing-edge flap up or down changes the flow conditions at the leading edge.

Hartzell Updates Current Programs And New Prop Offerings

AV Web

For the experimental market, Hartzell has added its Carbon Blended Airfoil propeller (the company has a re-naming contest for this propeller, with a goodie bag for any AirVenture attendee who comes up with a better name) that maintains the same performance gains as its all-metal prop with a savings of 20 pounds in weight.

What Our Members Are Building/Restoring — Missouri Kitfox 7SS

Inspire

He performed a lot of the build himself, including installing the landing gear, airfoils in the tail, and most of the tedious portions of construction. Richard Kampeter, EAA Lifetime 1128617, began constructing his Kitfox approximately four years ago.
