ROTAN refers to an early ROTational ANalyzer device developed in the late 1950s.

What was the commercial status of ROTAN?


One of the people who developed ROTAN was Walt Phelps, in 1957 or 1958. Development took place either in Building 86 or in Building 81, most likely Building 86.

The November 26, 1959 issue of TekTalk states that:

George Edens is largely responsible for developing the Rotan transducer system for velocity and acceleration systems.

In the early 1960s, still under the ROTAN label, the 183 Rotational Analyzer with its 182 optoelectronic encoder allowed up to 20,000 rpm.

In 1967, ROTAN was superseded by the Engine Analyzer System.
