Cowling Is Described.
The N. A. C. A. cowling is metal
shell, shaped good deal like a big
kettle with the bottom knocked out,
which fits over the radial airplane
around the irregular mass of the engine
without interfering with the cooling.
Without any increase in engine power
or changes In the airplane construc-
ton, this cowling has been credited
with increases of speed ranging up to
as high as 20 miles per hour. 1t has
figured in several aviation records dur
ing the past few years and now Is
standard equipment on many types OF
planes.
