Orenda Iroquois at S&S Turbines 2

It's been more than ten years of negotiations, but it's finally back in Canada ... in our shop.
This is the engine thought by many not to exist at all.
Sent to Bristol Aerospace for disassembly in 1958, it was never put back together, and stored in a giant warehouse in the UK. It escaped destruction, and sat for decades until it was put in a shipping container and sent to S&S Turbines in Fort St John BC.
The long term plan is to restore it to running condition, but it's going to take a great deal of very difficult work to get there...

Bravo good to see someone is taking the time to bring back something from the Arrow program. I saw a Iroquois in the Ottawa museum, is that one complete. I read that they were over hauling it but don`t know if it was ever tested. Where did you find yours and does it have the most resent blades. i ask this because the earlier prototypes had minor vib. problems that a new set of blades was suppose to cure.

@mikekrau The one in Ottawa is complete, but has never been run.

Ours is X-116, which was the last of the prototypes... the next ones were to be production units. X-116 has all the latest developments which were to be incorporated into the subsequent production run.

Are the turbine blades from that era all stainless steel?

[AgentJayZ]

@faffaflunkie Turbine blades , from the very beginning, have been made of refractory, high-nickel alloys like inconel, although the alloys used now are much superior to inconel. The metal must not lose its strength or stiffnes at sustained temperatures of over 1000 deg F.

All the compressor blades in the Iroquois are made of titanium alloy, which is light and stiff, but would catch fire at 1000F

Just out of curiosity what is that smaller engine shown to the left on the jack?

[AgentJayZ]

@FrontSideBus That is a nearly completely built RR Spey. Its waiting tp have the LP tubine installed.

whats the most exotic engine S&S has ever tested as in what was its nation of origin

@fatlady57 According to wiki, 20,000 lbs dry, 30,000 lbs with afterburner. Simply insane for late 50s standards.
