- A low-speed experimental investigation of the effect of a sandpaper type of roughness on boundary-layer transition
- Report describing the effects of an area of roughness on the velocity and turbulence measurements of an airfoil. It details the effects of the size, location, and height of the roughness on the Reynolds number. From Summary: "An investigation was made in the Langley low-turbulence pressure tunnel to determine the effect of size and location of a sandpaper type of roughness on the Reynolds number for transition."
- A theoretical study of the effect of forward speed on the free-space sound-pressure field around propellers
