installation of Diesel engine Venersss,,
is of interest, because il works aretI,.
important success in the various -,
in the evolution of naval engines II.
navy designed and built the frs. s,ss
ship with turbine engines about mi,
years ago. The turbine marked s.w.
proyement in economy over the W..
rocating engine, but to attain its gr,r.
est efficiency the turbine must be "a
at speed too high for the ship's on.
peller. Naval engineers, therefore Il.
veloped the geared turbine to mee,tt,
objection.
Steps In Advancement Traced
The U. s. s. Neptune was The in
big. ship in the world TO be drirea +
a reduction gear. Then naval eari
neers designed and built the &. 8.
Jupiter, which was the arst big sAi
to have electric drive. and the q. S.;
hauniee, which was the 6rst BIZ Dbl
to have Diesel cngine drive. IRE "a.
step in tn development vas the Z,
signing and building of the U. 81
New Mexico, in which oil-burNa
boilers furnish the steam which dria
turbine generators, which in turn e,s
crate electricity for use in the eisr.ri
motors which drive the ships pr
pellers.
The next step will be the ship
which Diesel engine generators fai
nish electricity f. driving the mai
prnpelling motors, and for all 9th,
machinery in the ship, and in whit
boilers will be used FOR heating pul
poses. The installation of the Dies
engine generators in the Maryla-,
Colorado and West Virginia will pr
vide for thorough test of these e.;
orators under service conditions q
may enable naval engineers TO devels
better Diesel engine generators. WIKI
will in turn be installed in the ner
ships the navy builds.
