Finding whether or not your airplane is in balance is all about finding the loaded airplane Center of Gravity or CG. Once you have this, you can compare it to the charts or tables the manufacturer gives you to ensure that it is within acceptable limits. The CG cannot be too far forward ...
Wind force on the sails causes a sailboat to heel. Resistance to heeling, called righting moment (RM),results from the lateral movement of the boat's center of buoyancy away from the center of gravity (CG). Righting arm and righting couple...
This video shows how to use a 2D layout, Geometric relationships and Excel to calculate the Center of Gravity CG and the Mean Aerodynamic Chord M.A.C. for a flying wing / Delta wing aircraft. Share this: Email More Loading... Lewis Ascender – Aircraft of the Month ...
To launch, the pilot must run down a slope to get air moving across the wing at about 15 to 25 miles per hour (24 to 40 kph). This movement of air over the surface of the wing generates lift, the force that counters gravity and keeps the glider aloft. Once aloft, gravity (the we...
The kite climbs into the air when the force of the wind and lift pushing it upwards is greater than the pull of the string and gravity. How to make your kite fly better… The force of the wind will be greater when the kite is on angle to the wind. The force of gravity will be ...
Fish rise and sink in water primarily using a swim bladder, which they inflate or deflate with oxygen to adjust their buoyancy. The swim bladder's volume changes allow the fish to displace different amounts of water, balancing the forces of buoyancy and gravity. Some fish, like sharks and ...
When you deal with massive bodies like the Earth, however, which has a mass of 6 x 1024 kilograms (see How much does planet Earth weigh?), it adds up to a rather powerful gravitational force. That's why you're not floating around in space right now. The force of gravity acting on ...
A skydiver exiting an aircraft will instantly experience the pull of gravity -- the force of weight. If he or she is wearing a wingsuit, then the suit's airfoil will provide lift. However, the airfoil isn't large enough to accumulate enough lift to push the flyer's weight upward through...
The unique design of the radial engine offers advantages in certain applications due to its compactness and efficiency. If you have ever seen a World War II bomber like the B-25 or the B-17, or if you have ever seen or been on an old commercial airplane like a DC-3, then you are ...
to move right, a rear flag with the right foot behind and to the left will shift your center of gravity farther left, thus more in line with your supporting hand and foot. This body position is more stable, and it becomes easier to funnel upward power from your left foot into your ...
