Let’s try to build special gliders with round wings. Will Bernoulli’s Principle allow them to fly like regular gliders?
Who will be able to make the glider travel the greatest distance?
In theory, the parachute should descend slowly and allow the weight to land smoothly. When you drop the parachute, the weight pulls down on the threads. This opens up the large piece of plastic which then uses the air resistance to slowly descend. The larger the area of the plastic, the greater the resistance and the slower the descent of the parachute.
Creating a small hole in the middle of the parachute allows air to pass through it rather than flow from the side; this should help to stabilize the descent of the parachute.
An important concept regarding flight has to do with rapidly displaced air and the consequent reduction of the pressure around it.
If the air pressure is higher underneath a moving object, an upward force is created that will cause it to take off.
The shape of the helicopter that we will try to build can also be found in nature. Many seeds have “wings” so they can glide in the air and have a greater chance of germinating. An example is the seed of the Sycamore tree.
