Inspired by and directly modeled after the ancient Indian (Sikh/Punjabi) battle weapon, the Chakram, an Aerobie is a flying ring used in a manner similar to a flying disc (Frisbee), for recreational catches between two or more individuals. The Aerobie is a ring, rather than a disc. An Aerobie is also lighter, and is more stable in flight. It can be bent to tune it for straighter flight. Since it has very low drag and good stability, it can be thrown much farther than a flying disc. The ring is only about 3 mm (0.12 in) thick. The Aerobie was used to set two former world records for thrown objects.
Designed in 1984 by Stanford engineering lecturer Alan Adler, the Aerobie has a polycarbonate core with soft rubber bumpers molded onto the inner and outer rims. The outer rim has a spoiler designed to impart stability.
"Aerobie" also refers to other products made by Aerobie, Inc.
In the 1970s, Alan Adler began attempting to improve the flying disc, considering its design characteristics. He tried streamlining the shape to reduce drag, but this resulted in a disc that was more unstable in flight. Eventually, inspired by British accounts of deadly Indian weaponry and martial arts, he turned his attention to the ring shape of the Chakram, a formidable Punjabi weapon used by the Sikh of India. This led to the development of the predecessor of the Aerobie, which was called the "Skyro". About a million of this model were sold. In 1980, it was used to set a Guinness World Record throw of 261 meters. It lacked the spoiler rim of the Aerobie. It had low drag, but was stable at only a certain speed. The later introduction of the spoiler, which balanced the lift, made the ring stable "over a wide range of speeds". After testing several models, the ideal shape was found, and the Aerobie was produced. Adler founded Superflight, Inc. in 1984 (now known as Aerobie, Inc.) Since then, Adler and the company have produced 12 other sport toy products.
The Aerobie allows for throws over unusually long distances. It flies faster and farther than a common flying disc. When well tuned, it can fly in a straight line, "like a puck on an invisible sheet of ice". It does not have the tendency to roll when thrown level, as a flying disc does. But similarly to a disc, an Aerobie can be thrown in a curved path by throwing it in a slant. Its lift depends on its speed relative to the air. Therefore, throwing into the wind makes it fly higher. Throwing with the wind makes it fly lower.
The Aerobie's ring shape allows it to be caught in a variety of different ways. For example, it can be caught by thrusting a forearm, the head (when the ring is thrown high), or even a foot through the middle. Games such as "Aerosticks" and Aerogoal are designed specifically for the Aerobie.
Disadvantages, special care
An Aerobie ring does not float in water. The ring can be damaged if abused. A thrower must take care not to throw too hard when throwing to a partner. However, it will slow down if thrown at a high angle. It can be easier to lose than a flying disc, especially over long distances: its low profile can make it hard to spot on the ground, and, in particular, it gets caught on tree branches more easily.
The Aerobie is best thrown in a wide open area such as a football or soccer field, away from bodies of water, with adequate light.
The 13 inch (33 cm) Aerobie Pro was used to set the Guinness World Record two times for the "longest throw of an object without any velocity-aiding feature". The Aerobie's first Guinness World Record was set by Scott Zimmerman at 1,257 feet (383.1 meters) in 1986 at Fort Funston, San Francisco. The 1986 record was broken by Erin Hemmings with a throw of 1,333 feet (406.3 meters) on July 14, 2003 at Fort Funston. Hemmings' Aerobie was airborne for 30 seconds (not an official measurement) and was the first thrown object to break the quarter-mile barrier (or 1,320 feet).
Previous to the 1986 record, the Aerobie held the world record at 1,046 feet, 11 inches. It does not appear that this was recorded by Guinness. On June 7, 1988, the Aerobie became the first object to be thrown across Niagara Falls with a throw by Scott Zimmerman. In April 1987, Zimmerman threw a silver dollar taped to an Aerobie across the Potomac River.
Since the introduction of the Aerobie, Superflight has offered reward money for various landmark throws. While details of the earlier rewards are unclear, the current reward is $1,000 to anyone who sets the Guinness World Distance Record.
A "Maximum Time Aloft" (MTA) boomerang was carried on the winds a distance of 1,401.5 feet (427.2 meters). It was thrown by David Schummy on March 15, 2005 at Murrarie Recreation Ground, Australia. The boomerang was not propelled that distance by the velocity of the throw; rather, it was carried by the winds.
