Techie Tuesday: What is Lift?

In last week’s Techie Tuesday about De-icing, I wrote that the main reason airplanes get de-iced is so that the wings stay clean in winter weather which allows them to create lift. But what is lift and how does a wing create it? That’s what today’s Techie Tuesday is all about!

Whether the airplane is a tiny two-seat Cessna 152, a massive Boeing 747 or something in between, every airplane takes to the sky because its wings generate lift. The truth is that lift is a fairly straightforward concept to understand. It has everything to do with the shape of the wing, the speed of the air going over and under the wing and the resultant pressure difference that creates.

Of course, it’s easier to understand lift if you can see it, not just read about it, so I’m linking to a really good video on YouTube that is all of 1 minute and 33 seconds. So check it out! If the video doesn’t make lift clear to you, post a comment with your question and I’ll do my best to answer it for you.
