radiator on the side of the fuselage or on the wing would be
preferable from the aerodynamic viewpoint, but this kind of
radiator did not seem to be sufficiently perfected to with-
stand the vibrations during very long flights.
The fuselage section is elongated in height (Figs. 2 and
3) and terminates in a point at the bottom (Fig, 4). This
shape enables, by the simultaneous use of a cabane and a sys-
tem of brace wires, the utilization of a very light wing with
a very large aspect ratio. The cabane struts and wires (in-
cluding the two pairs of wires below the wing) weigh only 90
kg (198 lb.), instead of 240 kg (529 lb.) which would have been
necessary if four steel struts with aluminum fairing had been
used. The weight of the wing itself is only about 50% of that
of a cantilever wing having the same aspect ratio of 8.7. The
fineness of the whole airplane is-17 when the wheels are cowled
and 16.5 when not. This figure can be increased to nearly 19.5
by eliminating the landing gear. A rectangular model with an
aspect ratio of 6, with the same profile, gave a fineness of
20. An elliptical model, like the B 110, gave a fineness of
22. 'In both cases the maximum Cz is very high (100 C =
160). The propeller was lowered as much as possible, so as to
bring the slipstream below the wing. The distance between the
propeller and the leading edge of the wing is 4 m (13.12 ft,).
The wing, with a span of 26.5 m (86.94 ft. ),had to be made in
three parts, so that it could be transported along the road to
Here’s what’s next.
