Rotor (ride)

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 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.
