Jaguar APU tech questions
Hello.
ATC Cadets have been given what we believe is a Jaguar APU for disection. Best we could find since there aren't any complete engines (or even many airframes) round these parts for them to look at. We managed to get a tour of the GE engine facility at NantGarw for a look over some GE and RR motors for 747s etc but having the real thingon a bench is even better!
Any pics or diagrams you could mail to me? Just be nice to know what is meant to have gone where. I only know RB211-535s and big piston jobbies.

I think the Harrier APU was the same....

Its more than likely a Microturbo - DCAE Cosford have gifted a few of those to Air Cadet Units lately.
Just checked with the guy who packed them up and they are Jag Air Starter Microturbos so Exriggers link is spot on.

If it is a Jaguar Air Producer (not APU) you will need lots of other bits and pieces like the oil tank, dual pump and Igniter unit and Fuel/Oil block (basically the FCU) as well as some electronic gimmickry (23K?). These were scattered around the airbrake bays of the Jaguar (Oil tank and Fuel/Oil block in the right bay, Air Producer, HEIU and 23K in the left bay) and not physically attached to the spinny windy bit. May have some notes from decades ago will try to look them out if you're interested. Seem to remember it idles at 80+%.
Exriggers link shows all the bits and pieces very well

Thanks, guys.
It is most certainly the SAPHIR unit that is sat on the bench. Starter unit is still on there plus theducting on the other end. No controllers with it but there is a spare hot section.
Question is....what to do with it. Might be a shame to cut open a useable unit. Anyone have something appropriate to trade it in for? We only got it so that we could see the working parts of an engine.
I'm bringing a Briggs & Stratton mower engine in so that we can open it up, put it back together and then run it. Much more fun than looking at books!
I brought my aeroplne over a few weeks ago and we ran the engine up for a few minutes. My prop-swinging arm is still a bit sore. Stale fuel!

Oil tank in the other Airbrake bay.....
400 starts before the RAF would bay maintain it, then another 500 starts before Mircoturbo would charge the earth to recondition it.. We never counted the ground runs.......

Has anyone had any success getting one of these gifted to an ATC squadron operational.
We are trying to get one of 4 we just got operational but all 4 appear to be missing the combustion chambers and we are at the moment trying to see if cosford have any that they could give us or get the specs to get our own manufactured.
We are planning on sectioning at least one of them, but nothing is quite the same as a working turbine and we have the experience to get it done, if anyone has any tips having done either any and all advice is more than welcome.

Personally I would not go there. These things are NOT toys.
The running system for these are fairly complex and in regards to the Jag system take quite abit of room. They must also be run outdoors so i think your neighbours would be a little upset. Also a Centrifugal Compressor operates at a very high RPM. Failure could have major consquences and no insurance policy would cover it.

To tag on to Alber Ratman's post there,
The Jag APU is not well known for it's reliability, and there have been many occasions where the APU has spat it's teddies, along with molten turbine blades, through its exhaust and airbrake bay.
Personally, that's not really a risk I'd want to be taking around youngsters.
