Nene?

Further quick search - Is it a Roller at all?

[18-Wheeler]

Further searching shows it most likely to be an early Avon.
That right?

[18-Wheeler]

No, a Nene has angled burner cans ->

Whereas an early Avon (I'm guessing) has parallel cans ->

So all going well, I've got myself an Avon .....

Doesn't look like an Avon to me, and it is definitely not a Nene, which had a double-sided centrifugal compressor. Scale would help. It looks small to me and may be an experimental VTOL engine. The Germans tried a VTOL with a bank of small vertical engines plus a big one for forward flight.

18,
Dick may be right - it looks a bit too small to be an Avon - that engine just about filled all of the back end of a Hunter. It might be an RB-166 - an engine that started as a lift engine but was used as takeoff assist for Hot Weather operations on a Trident 2E (Think I've got the right model). The R stood for Rolls & the B for Barnoldswick (same as RB-211). IIRC it had the highest thrust/weight ratio of any turbojet in (then) commercial use.

I'm pretty sure it's an early Avon, it's just lacking the exhuast ducting so it looks short.

It's an early Mk Avon. Those tripple bleed valves give it away. The later Mk's had sliding gate valve type bleed.

An Avon is also the most likely candidate as that is what was fitted the RAAF's Sabres (following an almost total re-design of the entire aircraft by GAF to get the bloody thing to fit).

Thanks guys.

I may be getting it, not sure yet.

[Doctor Teeth]

It's not an RB162 which was used as the Boost Engine on the Trident 3 which I think ICT_SLB was referring to. That baby didn't have separate combustion cans and also had GRP compressor cases and blades, except for the final stage blades which I think were Kevlar.

It looks like an AJ65 Avon minus the inlet. There's a picture of it in the book "The jet engine" by RR. It's on page 94 in my edition. (4th Edition 1986)

Ah never mind .... I missed out on getting it.
My dream jet car will have to wait. :(
Thanks anyway guys.

I hear the RAAF doesn't use all of it's F-111 a/c, perhaps you could put the enigne in a Roller, car that is...... :}
