As my first blog post ever, this will probably be slightly unpolished, as I see how this all works.
|The port main (boost) turbine enclosure (left) and the local controls for all propulsion gas turbines (right, see below for better photo). I never did figure out what the Tabasco sauce was for.|
|The starboard Allison cruise turbine within its enclosure. The compressor stages are to the left, while the turbine is to the right.|
The propulsion gas turbines are mounted backwards (compared to an airplane), with the compressor intakes pointed aft (left in the photo) and the turbine and exhaust pointed toward the bow (to the right). The shaft to the gearbox comes off the compressor end of the engine.
|Starboard cruise turbine enclosure with insulation on the exhaust seen at the forward end.|
|Looking aft at the exhaust ducting from the starboard cruise turbine.|
|Port gearbox. Note that the inspection ports are painted red (port) and green (starboard) to help identify which gearbox is which.|
|Looking forward from behind the starboard gearbox. Protective wire mesh at the bottom of the photo is probably covering where the propeller shaft exits the gearbox.|
|The local control panel for the four propulsion gas turbines is located between the two main (boost) gas turbines. This panel is generally manned whenever the engines are started, and can provide local control if contact with the MCR is lost.|
The ship's power generating equipment is located in the Auxiliary Machinery Room (AMR), immediately aft of the Engine Room.
IROQUOIS will pay off this spring, just shy of 43 years after she was commissioned into the Royal Canadian Navy.
