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 33 revolutions per minute. The rotation of the barrel creates a centrifugal effect equivalent to almost 3 g. Once the barrel has attained 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.
Although Hoffmeister was the 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.
- Australia – Three Rotors were built in Australia based on Hoffmeister's design. All had been demolished or destroyed by the 1990s, although a slightly redesigned Rotor was rebuilt for Luna Park Sydney in 1995, which is still in operation.
- United States – Several Rotors have been constructed in the United States since the 1960s. Though most of these have since been demolished and replaced by other rides, there are rotors still in operation at some places, such as Canobie Lake Park in Salem, New Hampshire ("Turkish Twist"), Frontier City in Oklahoma City, Oklahoma ("Tumbleweed"), Sylvan Beach Amusement Park in Sylvan Beach, New York, Worlds of Fun in Kansas City, Missouri ("Finnish Fling"). Another Rotor, with an observation platform, appears at the yearly Puyallup Fair in Puyallup, Washington.
