Part I of this report evaluates a computer solution for the centrifugal stresses in rotors of arbitrary cross section, as proposed by Lt. R. A. Johnson in 1965- This solution was found to be unstable and in its present form is unacceptable. Part II is an evaluation of the hot spin test unit of the United States Naval Postgraduate School. This facility was found capable of measuring centrifugal strains with excellent accuracy. Part III presents a new and original analytical solution for the stresses in any conical rotor of constant thickness. The theoretically predicted stresses are found to be in close agreement with the measured values for the particular rotor tested.

Johnson, Robert A. (Monterey, California: U.S. Naval Postgraduate School, 1965);Many rotors of recent design must run at the highest possible peripheral speeds, for example, gas or vapor turbines for space flight. Therefore, to reduce weight, a more accurate and adaptable solution is needed. Although ...
The application of a laser Doppler velocimetry system to flow velocity measurements in a transonic compressor. Harrison, Jeffrey Alan (Monterey, California. Naval Postgraduate School, 1978-12);A laser doppler velocimeter (LDV) system was developed and utilized to measure the flow velocities in the axial and tangential directions behind the rotors of a single stage transonic compressor. The backscatter mode ...
