cruising turbine

Separate cruising turbines were also fitted to the outer shafts.

The cruising turbines were also removed which simplified the ship's machinery at a small cost in power.

Cruising turbines competed at first with reciprocating engines for fuel economy.

The cruising engines were replaced by cruising turbines in 1907.

A geared cruising turbine was provided on the center shaft for fuel economy at low and moderate speeds.

A cruising turbine was built into the casing of each wing turbine.

Each had a high-pressure, a low-pressure, and a cruising turbine coupled to a single shaft.

A cruising turbine was also coupled to each inner shaft, although these were not used often and were eventually disconnected.

In engineering, cruising turbines were re-introduced with the Tucker and Sampson classes.

Cruising turbines were also fitted on the outboard shafts in these ships to improve fuel economy at low speeds.

Features that improved fuel economy included boiler economizers, double reduction gearing, and cruising turbines.

The remaining ships had two shafts with geared turbines and no cruising turbines.

A solution that proved useful through most of the steam turbine propulsion era was the cruising turbine.

Wartime builds omitted the cruising turbines originally specified and carried by the pre-war sub-group.

Double reduction gearing also reduced the size of the faster-turning turbines and allowed cruising turbines to be added.

These included small reciprocating engines and geared or ungeared cruising turbines on one or two shafts.

However, as in the Farraguts, the main turbines had single reduction gearing and no cruising turbines, limiting their efficiency.

After contract award, Bethlehem requested that their design be modified to use less-complex single-reduction gears and no cruising turbines.

However, once fully geared turbines proved economical in initial cost and fuel they were rapidly adopted, with cruising turbines also included on most ships.

Unlike earlier designs, which were designed for home fleet service, they were designed for colonial use, with higher freeboard, cruising turbines and better ventilation.

The ships were required to be powered by steam turbines, with cruising turbines fitted to improve range, fed by oil-fired boilers.

They were Parsons-type reaction turbines built by Bethlehem Steel, with single-reduction gearing and no cruising turbines.

The main steam turbines were impulse-type (also called Curtis turbines) and included cruising turbines and double-reduction gearing.

The central engine room had two each low-pressure ahead and astern turbines as well as two cruising turbines driving the two centre shafts.

However, during construction modifications were made to again increase boiler capacity and add cruising turbines which returned to the nominal power output of the Caroline class ungeared ships.
