Combustion chambers

I think we have a winner! Wow – thanks for that Wyvernfan. A Python had never occurred to me, but it is a clear match both in the combustion chamber and the flame tube. Thanks again!

The Armstrong Siddeley ASX / Python also had slim combustion chambers of that design.

Here are some not very good pictures.
I`m still not altogether sure.

Just as an aside, your Goblin flame tube looks remarkably like the one in your Proteus cutaway.

I know what you mean. I do think our one is Goblin and the photo below of a Goblin engine shows the inside and outside of flame tubes quite well. This does seem to be a pretty good match to our example.

I hadn’t realised there were different flame tubes in Proteuses. If you are able to find a photo of a Proteus showing the same time of flame tube as in our example, I would be very grateful. It would just be nice to confirm that this is indeed Proteus and not something else.

Thanks for the responses. I think number 4 is Derwent, as it matches the dimensions of another Derwent tube we have. I am unsure about the proteus, if only because the drawing below seems to show a very different type of flame tube. It may well be Proteus, but it would be great if anyone has a really good photo of a cutaway Proteus showing the flame tube just to make sure.

Thanks again for all the information so far which has been tremendously helpful.

I`m not at all sure about the Proteus, but I am quite sure that the combustion chambers on some of them had those distinctive steps, rather than a smooth tapered diameter. They didn`t all have the same chambers by the way, there is more than one type.
I`ll have a look at work tomorrow for a picture.

That 2nd on in the first post looks like my BBQ lighter 🙂

I agree with you on No1.
No2 looks like a Derwent MkI, is the MkII similar?
I don`t know what a Goblin flame tube looks like, but there must be plenty of people on here who certainly do.
No4 looks like a later (Mk5 or 8) Derwent to me, but could equally well be a Nene, as Anon pointed out, I`m guessing on that.

I`m somewhat out of my depth when it comes to jet engines, as has been noted on this forum previously!

Derwent V?

The Derwent V tube looks a little too squat though it may be the camera angle/perspective. Could it be Nene?

Just my two penn’orth.

Pete,

That’s great, thanks. No suprise that you recognised the Welland flame tube! May I ask can you check the following to make sure that I’ve identified them correctly? I believe they are as follows:

Combustion chamber 1: Avro Canada Orenda
Combustion chamber 2: Rolls-Royce Derwent II
Combustion chamber 3: de Havilland Goblin II flame tube
Combustion chamber 4: Rolls-Royce Derwent V

Thanks again for identifying the other two.
