Among the various experimental data which are required in the discussion of the theory and design of the aeroplane, there are none of greater importance than those relating to surface friction, while at the same time there are none about which greater uncertainty prevails.Owing to the difficulty of separating skin friction from head resistance, very ...

Friction-Induced Skin Disorders—A Review
Dermatitis®, 2023Friction is unavoidable in activites of daily life and is associated with various dermatological disorders. A comprehensive literature review showed friction can induce epidermal changes, dermatitis, alteration of the dermis, diseases of abnormal deposition, alteration of the hair and follicles, nail diseases, pigmentary disorders, and skin tumors ...

There are currently three basic instrument types used for the measurement of skin friction: the sled, the spinning drum or spool, and the rotating disk. Static friction, a measurement of the resistance to slipping between the probe and the measurement area, may be accomplished with all three types.

Skin-friction coefficient is analyzed with consideration of variable physical properties. The skin velocity gradient is the only one unknown variable for evaluation of the skin-friction coefficient. Systems of numerical solutions on the skin velocity gradient are obtained with consideration of variable physical properties.

DURING the past year the increase in performance shown by certain American and Continental aircraft has merited the attention of all aircraft technicians. The performance is, of course, partly due to increase in horse‐power, but this is a small factor compared with the advance shown in the reduction of drag.

A balance is described which eliminates some of the disadvantages of the `classical' design of skin friction measuring devices. By revising the motion of the sensing plate, one of the major sources of error is removed. Further advantages of the new design are the relocation of the displacement coil remote from the sensing plate, and the displacement ...

A CONSIDERABLE literature about skin friction or boundary‐layer theory exists both in English and in German and there is general agreement as to the best practicable method of dealing with a change from model to full scale. In the resume now to be given no new ideas or facts are introduced.
