Wind Tunnel
Don your thinking caps, kids. Its time to learn about the value of nondimensionalized aerodynamic data.
Wind Tunnel
Pilots, especially those in low-powered aircraft, must always know how much energy they have available to maintain flight.
Wind Tunnel
Although we often consider maximizing airflow over the exterior of an aircraft, we sometimes neglect internal airflow design that can cause significant drag.
Mind the Gap
An ill-fitting joint where the wing joins the fuselage doesn't leap to mind as a foremost source of induced drag, but the effects can be significant.
Wind Tunnel
Increasing the weight of an aircraft will affect its performance in all phases of flight.
Wind Tunnel
Sometimes adding accoutrements, paint, interior embellishments and other must-haves can result in a weight penalty that is difficult to overcome.
Wind Tunnel
When the airflow separates from a surface, the result can be unsteady forces or turbulent wake shedding, neither of which is desirable.
Wind Tunnel
This month well look at another complex interaction between aerodynamics and aircraft structures that can cause structures to fail: fabric flutter.
Wind Tunnel
Stall flutter is the result of the elastic axis of a wings surface being aft of the aerodynamic center, resulting in instability. A vicious cycle of lift, twist, stall and lift may ensue.
Wind Tunnel
Barnaby Wainfan offers an explanation of how tail surfaces can be subject to flutter and how to avoid the potentially disastrous result.
In Case You Missed It
What’s New
An Aussie Outback SLSA debuts in the U.S., a floating battery eliminator works with the Lightspeed Zulu headset, and Trio Avionics introduces the Pro Pilot autopilot.
Aero ‘lectrics
When you land your airplane at a fly-in, you want it to look its best while staying safely and securely parked. Making your own coordinated tiedowns, chocks and more is one way to do that.
