In overall design terms, the PS.13 was similar to the RB.106, using a "two-spool" layout with low-pressure and high-pressure sections of the compressor for added efficiency.

With this in mind, Orenda pioneered work in the use of titanium in engines, with 20% by weight of the Iroquois (mainly the compressor rotor blades) consisting of this metal.

During the early 1950s, this material was in short supply, and the lack of knowledge of its physical properties and fabrication techniques created problems which had to be overcome.

Inconel was used to make the blades in the low pressure turbine assembly and the metal insulation blanket found at the rear of the engine.

Canadair, the sub-contractor, attached an Iroquois to the right side of the bomber's rear fuselage, near the tail, simply because there was no other place to mount it.

The Canada Aviation and Space Museum in Ottawa houses the nose and cockpit section of Arrow RL 206, along with various wing and fuselage components, and a complete Iroquois-2 engine, Serial Number 117.
