Download or read book Two-component Force Balance for Measuring Skin Friction and Side Force written by Eugene V. Horanoff and published by . This book was released on 1975 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A two-component force balance was constructed which measured simultaneously the skin-friction force (drag force on a missile) and the orthogonal side force (roll-torque producing force). The test samples reported herein were designed to demonstrate the measurement technique. They were fabricated from aluminum. A successful test was performed in the NAVSURFWPNCEN Boundary Layer Channel using these aluminum test samples.
