The experimental determination of the moments of inertia of airplanes (1934)
NASA Technical Reports Server (NTRS) · leaf 1
ferences between the values of I, W, and M for motion in a vacuum and the case where the pen- dulum is immersed in air arise from three effects: the buoyancy of the structure, the air entrapped within the structure, and the additional-mass effect. A dis- cussion of these effects follows. Buoyancy… … Viqubb 2.—Airplane and swinging gear arranged for the determination of the pendulum is used, the moment of inertia about an moment of inertia about the rani by the compound-pendulum method. axis passing through the center of gravity is given by pendulum only for the case where the swinging is done…
