Researches on ailerons and especially on the test loads to which they should be subjected

Researches on ailerons and especially on the test loads to which they should be subjected

Date: February 1, 1927
Creator: Sabatier, J
Description: Aileron calculations have hitherto given greatly differing results according to different authors. It seems to be the general opinion that it is only necessary to give the ailerons such dimensions that the airplane can maneuver well, that the stresses they must undergo are relatively small, and that they are strong enough if their framework is of the order of strength as the wings to which they are attached. This article will show that the problem is really quite complex and that it should receive more attention.

Determining the velocity distribution in the boundary layer of an airfoil fitted with a rotary cylinder

Determining the velocity distribution in the boundary layer of an airfoil fitted with a rotary cylinder

Date: May 1, 1927
Creator: Van Der Hegge Zijnen, B G
Description: In the closer investigation of the results obtained from a wing model with a rotary cylinder mounted in its leading edge (NACA TM's 307 and 354), the velocity distribution in the vicinity of the surface of the model was determined by a hot-wire anemometer. The results confirmed the belief that the rotary cylinder had considerable effect on the air flow, but demonstrated the fact that the direct influence of the cylinder is confined to a very thin layer in immediate proximity to the surface.
