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.
Design Process: Aileron Types
The size and planform of the ailerons are set by the roll-control power needed to meet flying qualities and maneuvering requirements. Once the designer...
Design Process: Ailerons
Last month we looked at roll control schemes for airplanes where high lift or other requirements do not leave enough room on the wing’s...
AirVenture Hail Shields
With thunderstorms and possible hail predicted for Wednesday night, AirVenture exhibitors and visitors found a new use for bubble wrap and moving blankets.
Thunderstorms did...
Flaperons, Spoilers and Drooping Ailerons
There are some situations where there isn’t enough room on the wing’s trailing edge to split the functions cleanly between an inboard flap and...
Design Process: Roll Control
The primary function of the wing is to generate lift, but it must also incorporate control surfaces to control the airplane in roll.
Design Process: Slots and Slats
Opening a properly shaped slot between the lower and upper surface of the wing near the leading edge can greatly increase the angle of...
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.
In Case You Missed It
Build a Custom Plenum That Will Work
For optimum performance, all it takes is a little bit of math and some fiberglass.
What’s New
