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.

Once designers had addressed every other drag-producing aspect of the biplane, they decided to get rid of the struts and wires bracing the wings—and the switch to the monoplane was made.

Today, monoplanes dominate, but biplanes came first. They had their advantages—and for some of today’s missions, they still do.

Nine simple rules, distilled from years of experience (making—and fixing—assorted mistakes), can help any aircraft designer avoid disaster.
Wind Tunnel
It’s all about lift, and knowing your airplane’s lift margin at a given airspeed tells you what the airplane is capable of.
Wind Tunnel
Contrary to popular belief, the frontal area of an airplane is not the most important determinant of drag.
Vortex Generators and STOL Performance
One way to solve the problem of flow separation—and stall—is by installing vortex generators on your kit aircraft.

While two-control airplanes were designed to make a pilot’s life simpler, they come with significant compromises.

Certain situations and configurations just call out for a ducted-fan installation. Barnaby Wainfan explains the benefits and drawbacks.
Wind Tunnel
Seemingly inconsequential alterations—even mounting an inflight camera on the airframe—can result in big changes to an aircraft’s handling and performance.

Builders are often in a rush to prove the airworthiness of their homebuilt projects, but thorough flight-testing is essential.
