Rosedale / Friday Night Glow League at Rosedale Park
« on: July 20, 2012, 01:49:08 PM »
Reposting this from general banter so it will be seen by Rosie throwers:

Don't miss the picnic at gazebo starting 7:30 - 8pm brats will be grilling, Scott "Gabby" Thompson's famous pasta will be served and Tippins pies courtesy Steve H!

"Come out and Beat the Heat on Friday nights at Rosie. Random draw doubles, payout by division. Format is 5 bucks a person 1 dollar extra for the ace fund since its not a club league. 4 dollars towards payout and 1 dollar towards course improvement. Handicaps are given for pairs of 2 pros, 2 ams, or 2 women. Pros are stroked and ams and women recieve strokes. Pro Am pairs play straight up. Pros compete against each others scores as do Ams. Pro payout is cash and Am payout is DDKC Cash. Come hang out and have a good time with people you know and love. New comers encouraged and regulars always appreciated. Hoping to have a great impact on the local disc golf scene with this league and encourage glow city wide. This week 7-13 we will be teeing off by 8:55-9. Starting next week we will be teeing off by 8:30 since we have a time limit due to park closure. If you have any questions feel free to contact me. I'm best reached by phone either at DDKC or on my personal cell. Lights will be available for purchase prior to league start courtesy of DDKC.

General Banter / Frisbee / Golf Disc History and Manufacture
« on: August 31, 2011, 12:23:07 PM »
Many may be interested to know...

Nearly 300 million frisbees have been sold since their introduction 40 years ago, for both organized sports and recreational play. According to Mattel, 90% of Americans have played with this flying toy at one time or another, translating to 15 million people enjoying the sport every year. Now, older versions of this toy have become collectors' items worth hundreds of dollars or more.

The frisbee's origins actually go back to a bakery called the Frisbie Pie Company of New Haven, Connecticut, established by William Russell Frisbie after the Civil War. The bakery stayed in operation until 1958, and during this period, the tossing of the company's pie tins, first by company drivers and later by Ivy League college students (some say it was cookie tin lids), led to frisbie becoming a well known term describing flying disc play in the Northeast.

Several years after World War II, Walter Frederick Morrison—the son of the inventor of the automobile sealed-beam headlight—and his partner Warren Franscioni, investigated perfecting the pie tin into a commercial product. First, they welded a steel ring inside the rim to improve the plate's stability, but without success. Then, they switched to plastic and the frisbee as we know it today was born.

The initial design, which incorporated six curved spoilers or vanes on the top, was vastly improved in 1951 and thus became the Pluto Platter, the first mass-produced flying disc. This design, which incorporates a slope on the outer third of the disc, has remained part of the basic design to this day. The Morrison Pluto Platter had the first true cupola (cabin in Morrison's terns) and resembled the concept of flying saucers (UFOs) depicted during this period complete with portholes. In 1954, Dartmouth University held the first frisbee tournament, involving a game called Guts.

The founders of Wham-O, a California toy company, became interested in this flying disc in 1955 and about a year later began production after acquiring the rights from Morrison. The name was changed to frisbee after the company heard about the pie tin game on the east coast called Frisbie-ing. (Wham-O first marketed the Pluto Platter in January of 1957, but didn't add the word frisbee until July 1957.) In 1959, the first professional model frisbee was produced.

It wasn't until the early 1960s when frisbees became the rage and soon organizations became established to promote sporting events, including the International Frisbee Association and the Olympic Frisbee Federation. The first game of Ultimate Frisbee, a sport of both distance and accuracy similar to football, was played in 1968 at a New Jersey high school. Now, it is played at nearly 600 colleges and in 32 countries. In 1969, the U.S. Army even invested $400,000 to see if flares placed on frisbees would stay aloft but without success.

During the 1970s, several organizations were formed to promote specific events, including disc golf, freestyle, and Guts. The Professional Disc Golf Association (PDGA) now has over 14,000 members in 20 countries playing on over 700 frisbee golf courses. Today, 40,000 athletes in 35 countries compete in Ultimate Frisbee. The formation of such associations led to world championships being held during the 1980s.

Today, organized competitions in nine different events (including disc golf and freestyle) take place each year around the world, under the auspices of the World Flying Disc Federation (WFDF). Established in 1984, WFDF has member associations in 22 countries and provisional members in an additional 28 countries. During Operation Desert Shield in 1991, frisbee was used to boost the morale of the 20,000 U.S. soldiers on duty in Saudi Arabia.

Design
Manufacturers of frisbees use computer aided design software to create a model. A prototype is then made to test the design. Sometimes, a wind tunnel and other sophisticated methods are used to test flying characteristics, depending on the type of frisbee. Manufacturing tolerances within a few thousandths of an inch are now incorporated into the design.

Designers are always looking for new ways to manipulate the physical properties that dictate flight characteristics by changing the design or shape in order to improve lift, drag, spin, angular momentum, torque and other forces that affect how an object flies. For instance, adding a small lip and concave edge to a disc greatly increases its stability in flight.

A major obstacle disk designers must overcome is this instability caused by gyroscopic precession, the tendency of spinning objects to roll right or left in flight, depending on the direction of their spin and where they get their aerodynamic lift. The closer the disk's center of gravity remains to its center of lift, the more stable and straight the flight.

As a spinning disk flies, its center of lift is near the front, or leading edge, of the disc and tends to pitch the disc upward. Because of the spin, much of the lifting force on a point near the disc's edge does not exert itself until about a quarter of a revolution later. Such gyroscopic precession pushes the disc up on the side, causing a sideways roll. This is why frisbees, which typically are thrown backhand to spin clockwise as viewed from the top, tend to roll left from the thrower's perspective in flight.

Once in the air, lift and angular momentum act on the frisbee, giving it a ballet-type performance. Lift is generated by the frisbee's shaped surfaces as it passes through the air. Maintaining a positive angle of attack, the air moving over the top of the frisbee flows faster than the air moving undemeath it.

Under the Bemoulli Principle, there is then a lower air pressure on top of the frisbee than beneath it. The difference in pressure causes the frisbee to rise or lift. This is the same principle that allows planes to take off, fly, and land. Another significant factor acting upon the frisbee's lift is Newton's Third Law. It states that for every action there is an equal and opposite reaction. The frisbee forces air down (action) and the air forces the frisbee upward (reaction). The air is deflected downward by the frisbee's tilt, or angle of attack.

Spinning the frisbee when it is thrown, or giving it angular momentum, provides it with stability. Angular momentum is a property of any spinning mass. Throwing a frisbee without any spin allows it to tumble to the ground. The momentum of the spin also gives it orientational stability, allowing the frisbee to receive a steady lift from the air as it passes through it. The faster the frisbee spins, the greater its stability.


The Future
The frisbee is expected to dominate the twenty-first century as one of the great sports and pastimes. Frisbee sports should continue to grow, as well as collector groups interested in preserving its history. Though other flying toys have come onto the market—such as boomerangs, cylinders, and rings—the flying disc will continue to provide more hours of entertainment to people around the globe than probably anything else ever invented.

Disc golf specifically is experiencing record growth. In each of the last three years the number of courses in the United States alone has increased by 10%. Such growth should continue since there are still many areas of the country that are not yet aware of disc golf and the benefits it offers.

Also, frisbee may some day be an Olympic sport. For a sport to be eligible for the Olympics, it must be played for two years in at least 50 countries. Ultimate Frisbee is already played in 35 countries and its popularity is growing, along with other frisbee sports.
