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...
