FACULTY OF ARTS AND SCIENCES. Special Meeting at University 5, 4 P. M.
Mr. Merrill began his lecture with a brief history of the development of the aeroplane, which is the only practical method of the three employed to elevate a heavier-than-air machine. The other two the use of vertical screws and the oscillation of wings, involve almost insoluble questions of...
Stability is of two kinds: transverse and fore and aft. The aeroplane in mid-air has two forces acting on it besides that of gravity, a tendency to turn over sideways and a tendency to pitch either backward or forward. To counteract the former, and thus gain transverse stability, the...
After demonstrating the principles of soaring, by blackboard diagrams, Mr. Merrill went on to explain the present weakness of the aeroplane, namely, the engine. It is the inefficiency of the motive power which has and still does limit the range and speed of the heavier-than-air machine. It is...
After the lecture Mr. W. H. Aitken, who has charge of the aeronautical exhibit at the "Boston 1915" exposition, gave several demonstrations of the Bleriot aeroplane by the use of a small paper model which was would up and propelled about the lecture hall.
