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.

Design Process: Droops and VGs

In general, there are two ways to increase the maximum lift of a wing. The first, as we have been discussing the past couple...

Design Process: Flap Types

Last month we took a look at the trade-offs the designer should consider when defining the flap system for the airplane. The choice comes...

Design Process: Flaps

Flaps change the geometry of the wing to allow the pilot to change the aerodynamic characteristics of the airplane to match the needs of...

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...

In Case You Missed it

Light Stuff

Another European SLSA reaches American shores in the form of Tecnams high-wing, high-style, partially carbon-fiber Tecnam P2008. By Dave Martin.

Flush Rivet Removal

There can be more than 10,000 rivets in an aluminum kit aircraft. Given that many opportunities for errors, you’ll surely need to replace a few.

The Dawn Patrol

When the rains came to Oshkosh, it wasn't enough to get the intrepid Dawn Patrol coterie down. Dick Starks says thanks for the memories.

What’s New

Cub Crafters introduces a Carbon Cub kit, a new study of LSAs may affect insurance rates, and AeroLEDs offers new LED anti-collision/landing lights; edited by Mary Bernard.
