Rotor (ride)

Enlarge picture
Interior of the Rotor at Luna Park Sydney. The ride is in mid-cycle, and the riders are stuck to the wall of the barrel by the force of friction due to centrifugal force. The yellow lines on the barrel wall indicate the level the floor is at during different points of the ride; the higher line is level with the floor when the ride begins.
The Rotor is an amusement park ride, designed by German engineer Ernst Hoffmeister in the late 1940s. The ride was first demonstrated at Oktoberfest 1949, and was exhibited at fairs and events throughout Europe during the 1950s and 1960s. The ride still appears in numerous amusement parks, although travelling variants have been surpassed by the Gravitron.

Design and operation

The Rotor is a large, upright barrel, rotated at 30 revolutions per minute. The rotation of the barrel creates a centrifugal force equivalent to between 1 and 1.5 g. Once the barrel has reached full speed, the floor is retracted, leaving the riders stuck to the wall of the drum. At the end of the ride cycle, the drum slows down and gravity takes over. The riders slide down the wall slowly. Most Rotors were constructed with an observation deck. The minimum rider height requirement for most Rotors is 36 inches with an adult and over 46 inches to ride alone.

All American Rotors were forced to be modified after an accident on Cajun Cliffhanger, which was a historic Rotor at Six Flags Great America. The floor was redesigned with a small plastic guard to prevent feet and toes from being wedged under the floor.

Although Hoffmeister was the original designer, most Rotors were constructed under license. In Australia, the Rotors were built by Ted Hopkins of Luna Park Milsons Point. In the United States, two main companies were responsible for production; the Velare Brothers and the Anglo Rotor Corporation. A dispute between these two companies was resolved when the construction rights to touring Rotors were assigned to the Velare Brothers, while permanent-standing Rotors (later becoming known as Chance Rotors) became the domain of ARC.

Appearances

Facade of Rotor at Luna Park Sydney
  • Australia - Three Rotors were built in Australia based on Hoffmeister's design. All had been demolished or destroyed by the 1980s, although a slightly redesigned Rotor was rebuilt for Luna Park Sydney in 1995, which is still in operation.
  • United States - Several Rotors were constructed in the United States since the 1960s. Most of these have since been demolished and replaced by other rides, although Chance Rotors continue to operate at Canobie Lake Park in Salem, NH, and Lake Compounce in Bristol, CT. There is also a Rotor in operation at the COSI Columbus Science Center in Columbus, OH. An unmodified Rotor, Finnish Fling, operates at Worlds of Fun. Another Rotor, with observation platform, appears at the yearly Puyallup Fair in Puyallup, WA.
  • France - A famous scene in The 400 Blows depicts Antoine Doinel (Jean-Pierre Léaud) riding a Rotor. Director François Truffaut is among the other riders.
