Besides working against gravity, an aircraft must work against the resistance of the air. Air always tries to slow down anything that passes through it. This resistance is called drag. The faster an aircraft flies through the air, the more drag there is. Basic science and aerodynamics may help us understand Motorized Paragliding. This particular simple engine may be simple and compound, but it is also an aircraft that allows us the opportunity to fly in very accessible means.
An aircraft fights drag with thrust. Thrust comes from the plane’s engines, which makes the plane move forward in spite of air resistance. Before the invention of jet and rocket engines, propellers provided the thrust for all heavier-than-air craft. A propeller pulls its way through air in the same way that a screw pulls its way through the wood. Each of a propeller’s three blades is shaped like the wing of an airplane. The surface that faces forward is curved; the surface that faces backward is flat. As a blade cuts through the air, air passes over the two sides. The speed of the air is greater when it passes over the curved side at the front, so there the pressure is less. This means that there is less pressure in front of the propeller than behind it. The propeller therefore moves forward, pulling the rest of the plane with it. So much for this illustration, I only wish I knew every detail of it. This is just to give you a hint on the science that I think lies behind Motorized Paragliding.
Motorized Paragliding, just like airplane must have a certain minimum speed of it to stay in the air. Below this speed, you may stall or fall to the ground. Motorized Paragliding also experiences disturbances like turbulence and it may be caused by all kinds of conditions in the atmosphere.
Gliders are aircraft that have no engines- that is when you land you turn off the motor of your paraglider. As a result, they have no thrust. A glider is launched by winching (pulling) it forward mechanically, or catapulting it into the air. But once in the air, glider pilots use the changing currents of air to gain lift. By controlling lift and drag, glider pilots can stay aloft for many hours at a time. But we have to take note that Motorized Paragliding also uses aerodynamic forces; it has paramotor and paraglider that produce thrust and in turn lift while the paraglider forms airfoil through the air pressure entering its vents. Cruising off the ground to soaring above the clouds, you can launch and go anywhere with Motorized Paragliding!
