Supersonic axial-flow fan flutter [PDF]
Lane's (1957) analytical formulation of the unsteady pressure distribution on an oscillating two-dimensional flat plate cascade in supersonic axial flow has been developed into a computer code. This unsteady aerodynamic code has shown good agreement with

Laser anemometer measurements in a transonic axial-flow fan rotor [PDF]
, 1989 Laser anemometer surveys were made of the 3-D flow field in NASA rotor 67, a low aspect ratio transonic axial-flow fan rotor. The test rotor has a tip relative Mach number of 1.38.

Effect on fan flow characteristics of length and axial location of a cascade thrust reverser [PDF]
A series of static tests were conducted on a model fan with a diameter of 14.0 cm to determine the fan operating characteristics, the inlet static pressure contours, the fan-exit total and static pressure contours, and the fan-exit pressure distortion ...

Experimental and analytical dynamic flow characteristics of an axial-flow fan from an air cushion landing system model [PDF]
An investigation was conducted to compare the steady-state and dynamic flow characteristics of an axial-flow fan which had been used previously as the air supply fan for some model air cushion landing system studies.

Broadband sound radiated from subsonic rotors [PDF]
Recent theoretical work on sound sources in subsonic turbomachinery is applied to the correlation of axial-flow fan and compressor noise measurements. Correlations are presented for directivity and sound-power spectra associated with broadband noise.

Experimental and Numerical Investigations of Air Cooling for a Large-Scale Motor
International Journal of Rotating Machinery, 2009 This article experimentally and numerically investigates the thermal performance of a 2350-kW completely enclosed motor, which is cooled through an air-to-air heat exchanger. The air in the heat exchanger includes external and internal flow paths.
