(b) One complete B}IV r 018 engine had been crated and brought' from
STI,SVURT to ~KUYBXSF r,V for testing, but work on this unit ended ahen the
turbine nozzles and blades were damaged by gas erosion.

technicians as the 022. ':Then it first-appeared on tho test bed this engine

series -was .the substitution of a single four-bladed propeller for the contra

in the S X,- C.0 the later series had an improved 5ompressor
which resulted in increased efficiency.. -The air -mass flow was approximately
