From albatrosses to slimy eels: Aircraft design and concepts inspired by nature 

Aerotime

Winglets and Sharklets Both Airbus and Boeing operate aircraft with wingtip devices that are designed to increase aircraft efficiency by removing drag. The devices would prove to “reduce wingtip drag” and increase “fuel efficiency by 6-7%” but would need be positioned uniquely for each aircraft type.

Wingtip Vortices and Wake Turbulence

Pilot Institute

This is called lift. Wingtip vortices are a byproduct of lift. Once the wing stops producing lift, the vortices dissipate instantly. Wing spoilers drastically reduce the lift generated by the wing. Its important because the lift is always produced perpendicular to the relative wind. Why is this important?

Video tip: The aerodynamics of induced and parasite drag

Flight Training Central

During your flight training, you’ll learn all about the 4 forces acting on the airplane in flight, including lift, thrust, weight and drag. This week’s tip takes a closer look at the aerodynamic forces that cause the rearward force of drag, including a breakdown of parasite vs. induced drag.

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

Pilot Institute

Many explanations on websites, videos, and even some textbooks oversimplify or misrepresent the true mechanics of lift. In reality, lift generation involves both Bernoullis principle and Newtons third law working together. Read on to understand Bernoullis principle and how it relates to lift the right way.

Learning Aeronautical Engineering From Historic Aircraft Designs

Vintage Aviation News

Studying historical aircraft helps students understand the development of flight and learn from early engineers about problems of lift, propulsion, stability, and material constraints. Often touted as the first successful powered aircraft, the Wright Flyer (1903) clearly shows lift, propulsion, and control.

The physics of mobility: an interesting comparison of road, rail, and air travel

Aerotime

Energy is always required for acceleration, to overcome air drag, as well as rolling and friction resistance of wheels on road and rail, and for “lifting work”, i.e., working against gravity. It must be noted that energy to overcome air drag is only required when the movement takes place in an atmospheric environment.

How Do Planes Fly & What Keeps Them In The Air?

Simple Flying

Although the science behind flight may seem complex, it boils down to the balance of four fundamental forces: lift, weight, thrust, and drag. Have you ever watched a plane take off and wondered how that big metal object full of people actually floats in the air?
