Aerodynamic performance of a 1.20-pressure ratio fan stage designed for low noise [PDF]
The aerodynamic design and the overall blade element performance of a 51 centimeter diameter fan stage is presented. The stage was designed to minimize the noise generated by rotor stator interactions. The design pressure ratio was 1.20 at a flow of 30.6

Three-dimensional inviscid analysis of radial turbine flow and a limited comparison with experimental data [PDF]
The three-dimensional inviscid DENTON code is used to analyze flow through a radial-inflow turbine rotor. Experimental data from the rotor are compared with analytical results obtained by using the code. The experimental data available for comparison are

Effect of tip planform on blade loading characteristics for a two-bladed rotor in hover [PDF]
A laser velocimeter was used to study the flow surrounding a 2.13 m diam. two-bladed, teetering model-scale helicopter rotor operating in the hover condition. The rotor system employed interchangeable blade tips over the outer 25% radius.
