    Why haven’t we made blow up wings to fly with them

    Just wondering because if wings are too heavy for humans to fly couldn’t we just use rip stop nylon (the material we use for hang gliders, paragliders etc) and inflate them and then we would have wings light enough for humans to flap and fly with I don’t know why humans haven’t done this?

    So who here has tried to make a homemade wind tunnel? My first attempt

    Hello all, i posted this on another forum but didn't get much response, I had an 18” centrifugal fan around around and wanted to see if I can push some real air to make a wind tunnel. I'm just a hobbyist, and like to build and modify cars, figured this would be something to look into. Looks...

    When a bird flaps it's wings up, doesn't the pressure drop below?

    I am trying to understand how birds fly. If you consider a plane, using it's engine & streamline shape of the wings, it can create a low pressure region above the wings and high pressure region below and this makes it fly and the upward force is proportional to the speed. Birds seem to flap its...

    I Can a microscopic insect fly by flapping rigid wings?

    While in quarantine, I've been reading a lot about some millimeter-scale flying robots, like DARPA's Nano Hummingbird and others.

    Aerodynamics - why wings create lift - current vs historical discussions

    My son and i were discussing aerodynamics and he brought up a paper from https://phys.org/news/2012-01-wings.html It seems that the latest discussions seem to completely discount the differential velocity of air flow as a cause of differential pressure, but point to a differential pressure...

    Airplane wings -- How do they work and why do they change shape?

    I just went on a Japan trip. In the airplane, besides throwing up my ball and phone, I was doing a little bit of studying. While the plane was in takeoff, in the middle of flying, and landing, I noticed how the wing positions changed. I already know how takeoff works. It works when the plane...

    Can surface roughness on wings improve performance

    How does AAW work? (Active Aeroelastic Wings)

    For a conventional wings, at high speed or fast roll, the leading edge of the wings will bend downwards. This will decrease angle of attack and subsequently lift. How does AAW make the wings bend the other way round? Is it due to the materials or the shape of the wings that is designed? If such...

    Automotive Spoilers vs Wings: A Car-Lover's Debate

    Can an airplane fly without wings?

    Yes it can, and surprisingly well. Conventional wings tend to be typically: 1. Large (lots of area) 2. Thin (thickness/chord < 15%) 3. High aspect ratio (span/chord > 6) A common example of a wingless airplane would be a lifting body. Benefits of wingless airplanes: 1. Compact (encloses...

    Is there just one correct way to calculate wing lift?

    Wings generate lift because of the curved shape of the top wing air flow faster over the top and sucked up the plane. This would be bad for a fighter jet flying upside down. Wright brothers plane wings are flat so the wing must be deflected down. So curved wings are just aerodynamic. Soo which...

    Car Wing Design for Downforce: Efficiency Explored

    Can a Wingless Plane Achieve Lift?

    In a large passenger plane wings used to create lifting force. But in order to create lifting force, body of a plane could be used as well. In order to create as much as possible lifting force you need to have as much as possible difference between upper and down streams of air. In order to slow...

    Effects of Wings in a closed environment

    Simple explanation - wings in an aeroplane
