• Experiments on the effect of suction on the flow due to a rotating disk
• Low-speed aerodynamic characteristics of NACA C012 aerofoil section, including the effects of upper-surface roughness simulating hoar frost
• Wind-tunnel tests on the 30 per cent symmetrical Griffith aerofoil with distributed suction over the nose
• Wind-tunnel tests on the prevention of boundary-layer separation by distributed suction at the rear of a thick aerofoil (NPL 153)
• Wind-tunnel tests on the use of distributed suction for maintaining laminar flow on a body of revolution
