Stability in aviation : an introduction to dynamical stability as applied to the motions of aeroplanes (1911)
Bryan, George Hartley, 1864-1928 · London : Macmillan · leaf 155
re gliding down uniformly under gravity, 6 would only be equal to a, and any value of 6 greater than a could only be consistent with steady motion if the machine were retarded by reversing the engines or by a sufficiently oreat head resistance. At the same time, we have to con- sider the… … Fl(!. VI. — DlAlJKAMMATIC ViEW OF A WkICHT Bll'LANE USED AT PaU.
