Having read that this engine was used in Concorde and was going to be used in the tsr2, what if this engine also found it's way in to an upgrade RAF CF-105 arrow?
I have nearly built my Avro Archer F3, which is a modified mid sixties version of the Arrow, and a pair of these motors would be a good upgrade to extend their usable life I was thinking. Any and all thoughts will gladly be appreciated.

The Iroquois 2 was:

Length: 231 in (590 cm)
Diameter: 42 in (110 cm)
Dry weight: 4,650 lb (2,110 kg)

The Olympus 593 Mk 610 was:

Length: 4.039 m (13 ft 3 in)
Diameter: 1.212 m (47.75 in)
Dry weight: 3,175 kg (7,000 lb)

The Olympus was considerably larger, both in diameter and length.  In weight the two engines were also considerably different.  You would need a longer wider fuselage and a change in the size of the wings to accommodate the differences.

I see, that's that idea out of the window then. Back to the drawing board. Thanks for the info Rickshaw :thumbsup:

Yes, the 593 was a MONSTER of an engine as well as being seriously powerful.

And you have to admire the Iroquois' designers for getting that much power out of a relatively small and light engine, the Iroquois thrust/weight ratio was quite a bit better than the 593's at 6.45 versus 5.4
Kit's Rule 1 ) Any aircraft can be improved by fitting longer wings, and/or a longer fuselage
Kit's Rule 2) The backstory can always be changed to suit the model

...and I'm not a closeted 'Take That' fan, I'm a REAL fan! :)

Well that was more or less the idea behind this project of mine, a bigger engined Arrow.  I've used a Mig 31 fuselage (with a highly modified forward fuselage to look more like an Arrow)

I had a thread going on the forum, but all the photos are gone because of the PB fiasco;

Hang on a mo... let's arrange the units in the same order and coordinate them:

The Iroquois 2 was:

Length: 5.9m ( 231 in ) this is just the dry section, not the afterburner
Length: 7.62m ( 300 in ) with afterburner as installed in CF-105
Diameter: 1.10m ( 42 in )  main casing
Diameter: 1.19m ( 47 in )  afterburner secion
Dry weight: 2,110 kg ( 4,650 lb) excluding starter and firewall
Mass flow:  190kg ( 420lb ) per sec

The Olympus 593 Mk 610 was:

Length: 4.039 m ( 159 in ) - this is the flange-to-flange length
Length: 7.1m ( 280 in ) - this is the overall length to final nozzle for Concorde
Diameter: 1.212 m (47.75 in)
Dry weight: 3,175 kg (7,000 lb) Flight in 1973 says 2,620kg ( 5,793lb )
Mass flow: 204kg ( 450lb ) per sec


The Iroquois was light partially due to extensive use of titanium but otherwise the engines are fairly close to each other.

Interesting.  Where did you get your data from, might I ask?  I only found the stuff I posted on Wikipedia...   :banghead:
