Frisbees fly so through the air thanks to their shape and ability to rotate. When you flick your wrist to send a Frisbee flying to a friend, you start the Frisbee spinning rapidly. It acts like a gyroscope, building angular momentum in the process. Angular momentum gives a Frisbee stability in flight.
Like an airplane, a Frisbee flies because of two forces: lift and thrust. Lift comes from air pressure underneath the Frisbee. Because the top of the Frisbee is curved, the air on top travels a greater distance as the Frisbee goes by. So the top air must go faster.
GLIDE 1 TO 7
Glide describes the discs ability to maintain loft during flight. Discs with more glide are best for new players, and for producing maximum distance. Beginners wanting more distance should choose discs with more glide. Discs with less glide are more accurate in high wind situations.
There is a corresponding pressure drop over the left side and that side will produce greater lift, and the disc will try to twist clockwise when viewed from behind. As mentioned above, the gyroscopic inertia acts to counter this, and the greater the spin, the higher the inertia.
The two main physical concepts behind the Frisbee are aerodynamic lift (or the Bernoulli Principle) and gyroscopic inertia . A spinning frisbee can be viewed as a wing in free flight with the Bernoulli Principle being the cause of the lift and the angular momentum of the disc providing its stability.
Spinning the Frisbee helps it fly by supplying angular momentum, which helps keep the Frisbee stable; the faster it spins, the more stable it should be.
The shape of the disc is an airfoil in cross-section which allows it to fly by reducing the drag and increasing lift as it moves through the air, compared to a flat plate.
The center of pressure will move forward-backward depending on the speed of your throw and the angle of attack. In the late stages of a disc's flight, it's flying slower and with a higher angle of attack (because it's falling toward the ground), so it experiences fade.
This is known as “nose angle”, and it is exceptionally important if discs are to fly far. Any amount of nose-up angle results in a lot of drag, which is converted into altitude, and then the disc stalls, and fades hard left, and short.
As you can see the frisbee's edge is slightly curved, just like an airplane wing. That helps a frisbee to generate lift. Lift is a force perpendicular to the direction of the airflow and in the case of the Frisbee lift pushes the Frisbee upwards.
By gluing together two or more layers (laminated construction), you will end up with a stiffer ring or disk, which will fly better. A way to further increase stiffness is to compensate for the "grain" of the paper by rotating the disks relative to the original orientation before gluing them.
UNDERSTABLE – An understable disc has a High Speed Turn number that is greater than its Fade number. For example, a disc with flight numbers 13/5/-3/1 would be considered understable.
The degree to which a disc resists high speed turn determines the disc's stability. Discs that have a lot of high speed turn are understable. Discs that have a moderate amount of high speed turn are stable, and discs that resist turning right even at high speeds are overstable.
Answer: Flying discs (including Frisbees) can be thrown in many ways. All involve spinning the disc to give it gyroscopic stability, and accelerating its mass to a certain velocity. Without spin, a disc will wobble and fall; without velocity, the disc will not go anywhere.
To force a disc to turn right, throw the disc with the outer edge raised, and pull through above your chest. This is called throwing anhyzer. If you do this correctly, the disc will start out turning to the right.
Is disc golf hard to play? Yes, disc golf is a tough sport and it is very hard to play. Trying to throw a small disc hundreds of feet accurately takes tremendous skill and practice. Disc golf is an extremely challenging sport that takes years of practice to master.
Discmania's Flight Ratings. All Discmania discs carry four ratings. These four numbers represent different characteristics of the flight. The four numbers are: speed, glide, turn, fade.
As it loses speed, it decelerates and gravity pulls it toward the ground. Which way it turns is largely dictated by the stability of the disc itself. The gyroscopic spin of an overstable disc like a Firebird or Destroyer will ultimately force it to go left at the end of a right-hand backhand throw.
Stand with your dominant foot pointed straight forward and your non-dominant foot at a 90° angle to the other one. When you're ready to throw, curl your wrist slightly back towards your body so that your elbow is pointing up and outward, then extend your arm straight out, releasing the Frisbee at the end of the motion.
The teams shall alternate throw-offs at the beginning of each period. All players must be on or behind their own goal line without changing relative position. A player on the goal line throws the disc toward the other team. As soon as the disc is released, all players may cross the goal lines.
Frisbee's name is a spin-off from a defunct Connecticut bakery, Frisbie Pie Co. New England college students often tossed empty pie tins around for fun, a habit that led them to refer to the Pluto Platter as a "frisbie."
Nearly 300 million frisbees have been sold since their introduction 40 years ago, for both organized sports and recreational play.
Throwing them at a distance less than that could result in catastrophic skips that do more harm than good. A seasoned disc golfer with average power will generally max out around 400 feet/122 meters at most.
