Download or read book An Approximate Determination of the Power Required to Move Control Surfaces as Related to Control-booster Design written by Harold I. Johnson and published by . This book was released on 1945 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: As a part of a general investigation of control boosters, preliminary calculations were made to indicate the sizes of control boosters necessary to move the controls of airplanes of various sizes. The analysis was based on the assumption that the controls were moved with a rapidity and amplitude equal to that measured with a fight airplane in simulated combat. A corollary purpose consisted in determining the effect on reducing booster-power unit size of incorporating an energy accumulator in the booster system.
