Barnaby Wainfan
Barnaby is a Technical Fellow for Northrop Grumman’s Advanced Design organization. A private pilot with single-engine and glider ratings, Barnaby has been involved in the design of unconventional airplanes including canards, joined wings, flying wings and some too strange to fall into any known category.
It Pays To Heed Convention
Barnaby Wainfan looks at unconventional flight-control configurations in the cockpit and why they can throw even a seasoned pilot.
Tail Surfaces and Aerodynamic Effects
Major aspects of tail design and how they affect the performance of an aircraft in flight.
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.
In Case You Missed it

Airplanes are surprisingly flexible, and changes in their shape can affect aerodynamic characteristics. Barnaby Wainfan explains how the two are coupled.
