5 Most Common Aircraft Flap Types (Explained by a CFI)

Northstar VFR

When flaps extend, they increase the camber (curvature) of the wing, which boosts the amount of lift the wing generates. By increasing the camber (curvature) of the wing, it produces more liftat the cost of additional drag. How Do Flaps Work? Some flap types also increase the surface area of the wing.

What Is Bernoulli’s Principle? A Simple Guide for Pilots

Pilot Institute

Bernoullis principle also applies to how carburetors and jet engine inlets work. Wing Camber Wing camber defines how much more curved the wings upper surface is compared to the lower surface. Jet Engine Inlets Jet engine inlets also rely on Bernoullis principle, although they use it differently than carburetors.

Mach Number Explained: What It Is and Why Pilots Use It

Pilot Institute

Why do jet pilots talk about speed in terms of Mach number? Jet aircraft often fly at speeds close to the speed of sound. For most aircraft with highly cambered wings or thick profiles, airflow accelerates over the top of the wing. Early jet pilots found this out while exploring high-speed jet flight. Here’s why.

Tailless Aircraft: How Airplanes Fly Without a Tail

Pilot Institute

Upward Deflection : Raising both elevons decreases the camber of the wing. Downward Deflection : When the elevons are lowered, the camber increases. This is a jet-powered tailless aircraft with low aerodynamic drag. Lift is reduced, and the nose pitches downward. This creates an increase in lift, and the nose pitches up.

The Role of Newton’s Third Law in Aviation

Pilot Institute

One is the upper wing surfaces curvature compared to the lower surface, called wing camber. High camber generally promotes more airflow deflection, thanks to something called Bernoullis Principle. However, its even possible to generate lift from a wing with symmetrical upper and lower surfaces, that is, without camber.

Everything You Need To Know About Ailerons

Pilot Institute

The asymmetry between the top and bottom surface of the wing is called wing camber. The downward movement of the aileron increases the asymmetry and, therefore, the camber while raising the aileron reduces the wing camber. This type of design is common in delta-winged aircraft such as fighter jets.

The Most Misunderstood Aerodynamic Concepts

Flight Training Central

Looking at the curvature or camber of a typical general aviation wing, the top has more curvature and thus surface area than the bottom of the wing. In a jet airplane, the engine pushes a blast of hot gases backward; the force of equal and opposite reaction pushes against the engine and forces the airplane forward.
