SOME FRENCH MACHINES AT THE SHOW
Bleriot and Spad
Three very interesting Spad machines are exhibited, interesting because, while retaining the characteristics of the Spads built during the War, they are, as regards two of them, designed for sporting purposes, having low-powered engines and consequently reasonable cost and upkeep. The third machine is a three-seater, with the two passengers seated inside an enclosed cabin.
The Spad monocoque type S 30 is small single-seater, with 45 h.p. Anzani engine. The wings are so arranged as to give the pilot a good view, and, while not very large, they are of sufficient area to ensure a low landing speed. The speed range is also very good, the maximum speed being in the neighbourhood of 87 m.p.h., and the landing speed about 37 m.p.h. The overall length is 19 ft. 6 ins., and the span 23 ft. 6 ins. The weight of the machine empty is 570 lbs., and in flying trim - with pilot and fuel for three hours - the weight is 880 lbs. The 45 h.p. Anzani engine is provided with a silencer which adds greatly to the comfort of the pilot. Strength has been especially studied, the machine having a factor of safety of 15.
The Spad monocoque type S 29 is a small two-seater, fitted with an 80 h.p. Le Rhone engine. The occupants are placed tandem fashion in the monocoque fuselage. The maximum speed is 102 m.p.h., and the landing speed just under 50 m.p.h. The length of the machine is 19 ft. 7 ins., and the span 25 ft. 5 ins. Empty the machine weighs 790 lbs., and fully loaded - with pilot and passenger and three hours' fuel - 1,230 lbs.
