It uses an actual gas turbine and consists of an axial compressor with 15 floors, six arranged combustion chambers to (90[degrees]) to the axial intake, a high-pressure turbine
single floor (first floor), which drives the compressor and auxiliary equipment, as well as a low-pressure turbine (second floor), which drives the load.
It also will further validate the advanced technologies incorporated in the engine, including the woven carbon fiber composite fan, the Twin-Annular, Pre-Mixing Swirler (TAPS) combustor, ceramic matrix composite shrouds in the high-pressure turbine
and titanium aluminide blades in the low-pressure turbine.
The part in question is a nozzle used to direct hot gases into the hottest part of the engine, the high-pressure turbine
After the steam from the boiler drives the high-pressure turbine
, the exhausted steam is returned to the boiler and reheated for driving to the medium-pressure turbine, and subsequently the low-pressure turbine.
The RT-35 Low K coating was patented by Chromalloy in 2006 and certified by the Federal Aviation Administration (FAA) in 2010 for use on the PW4000 second-stage high-pressure turbine
blade after a series of tests confirming its low thermal conductivity, high thermal cycle durability and other attributes.
Each 400 MW unit comprises a high-pressure turbine
(150 bar, 510AC), a two-flow intermediate pressure turbine (40 bar, 460AC), and a 497 MVA hydrogen-cooled generator with static excitation.
CFM International Engines flying through the volcanic ash cloud risk impaired compressor performance or even a compressor stall, as well as damage to the high-pressure turbine
blades and the turbine nozzle as a result of overheating, manufacturer CFM International has warned.
According to the report, a 14-centimeter blade -- one of 74 high-pressure turbine
blades in the rear of the engine -- fell off due to metal fatigue and expanded damage inside the engine after hitting other blades.
The high-pressure turbine
inlet section has been optimized to provide a more homogenous flow distribution in the entire inlet area to the stationary blade rings.
The petrol-pump product line makes up 90 percent of the total pump business and includes positive displacement, as well as low-and high-pressure turbine
pumps in a variety of in-line or in-tank applications.
Additional modifications to the T-700 engines include a new high-pressure turbine
(HPT), digital electronic controls and anti-icing bleed valve.
Under the contract, MHI will supply high-temperature, high-pressure turbine
blades and rotors, in addition to other parts, for use in the turbines.
