Since that airplane would show to even greater advantage with the
higher power of the Wasp, we now wangled a deal with Wright. We
actually persuaded good-natured Charlie Lawrance to turn his pet
airplane over to Chance Vought for the installation of a Pratt and
Whitney Wasp with which Lt. C. C. Champion, who had now joined
the Engine Section, was to take a shot at the world’s record for
altitude. With the completion of Chance Vought’s own Corsair, we now
had a brilliant two-seater that compared favorably in performance
with the hottest fighters, and thus gave us a stable with which
to make an assault on all the world’s records in their classes.
The admiral, a highly competitive spirit with a keen appreciation
of the value of world’s records and racing competition, now made
participation in these events a major Bureau project.
The names “Wasp” and “Corsair” had been selected by the Engine
Section, in response to requests from Pratt and Whitney and Chance
Vought. Little did we know at the time what distinction they would
one day attain. The Wright Apache focused attention of other
manufacturers on the characteristics of the Wasp; and Boeing, after
testing an engine in a converted FB-1 fighter, immediately put a new
one in the works to be called the “F2B.” Curtiss made a conversion
of one of its single-seater Hawks, replacing the D-12 with a Wasp.
The first Wasp engine to be flight tested was flown in a Curtiss
Hawk and thus became a sort of monument to the reluctance Curtiss had
shown by their failure to develop their own R-1454 engine. It also
nearly became a monument to the failure of the Pratt and Whitney Wasp.
For on the one-hour endurance test over Long Island, Temple Joyce,
then test pilot for Curtiss and one of the best-known figures in
aviation, grew tired of the monotony of cruising back and forth
and decided to vary the routine with some acrobatics. But when he
pulled back the stick and booted the rudder to do a nice snap roll,
something snapped in the Wasp and Temp had to make a forced landing
on the Curtiss field. The competitive Wasp in a competitor’s airplane
had gone sour on its test flight! Consternation reigned in the Engine
Section—matter of fact, it really poured.
Examination disclosed that the crankshaft counterweight had sailed
out through the crankcase. Now the cheek had been designed with
ample margins for the stresses of centrifugal force, and the failure
remained a mystery until I recalled a lesson learned as a student
in the Sperry Gyro Compass School several years earlier. No one had
anticipated the effect of gyroscopic forces like those set up in a
snap roll. Now George Mead took these in hand and strengthened the
shaft to withstand them. With this change, the Pratt and Whitney Wasp
came to stay.
