Barnaby Wainfan is a principal aerodynamics engineer 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.

Laminar- vs. Turbulent-Flow Airfoils

Airfoils break down into two general classes based on the behavior of the boundary layer.

Design Process: Airfoils

Once the size and planform of the wing have been determined, it’s time to choose (or design) the airfoil.

Design Process: Stall and Roll Damping

Last time we took a look at the effect of twisting the wing. Wing twist is used to adjust both the spanwise distribution of...

Design Process: Twist Effects

For the last few months, we have been looking at how the planform affects both the distribution of lift and the distribution of lift...

Design Process: Distribution of Lift Coefficient

In the last few months, we have explored how planform and taper affect both the distribution of total lift across the span and the...

Design Process: Planform Effects on Structure and Weight

Last month we took a look at how the planform of the wing affects the spanwise distribution of lift along the wing. The shape...

Design Process: Planform Effects on Span Loading and Drag

Last month we started our discussion of wing planforms with a look at the various planform shapes in use. We now turn our attention...

Design Process: Planform Shape

Last month we took a look at the effects of span and aspect ratio. At this point on the design of the wing, we...

Design Process: Span and Aspect Ratio

At this point in the design process we have determined the wing area. The choice of high- versus low-wing and structural concept of the...

Design Process: Cantilever Wings

Last month we began our discussion of the structural layout of the wing with a look at externally braced wings. We now turn our...
