Projectile Lubrication by Melting Rotating Bands
Abstract
Sliding experiments carried out in the laboratory with a pin-on-disk machine produced appreciably higher coefficients of friction than the actual values measured for projectiles sliding down cannon bores. Although the pin surface melted, the coefficient of friction was at least an order of magnitude higher than expected for liquid film lubrication. The sliders in the laboratory experiments were, of course, much smaller than actual rotating bands and the bearing pressure was limited by distortion of the sliding pin.
