Have a close look at the above picture and then look at it again.
Which side should the heat be coming out from? Take a look at the pipes extending from the engine. Are they Bleed Air pipes (in which case it's coming from the compressor) or is it some something else.
Look at it 4 times and tell me which side the heat should be coming from.

I believe that the picture stands correctly. What do you think?

(Sorry if the picture doesn't download in time, Must be the server)

well, given that a jet engine works on the same principle of compression and combustion as an internal combustion engine I'd have to ask why 'the heat' (shall we call it thrust?) is coming out the 'wide end' of the engine, rather than the narrow (compressed) end.

I think it's wrongly depicted....or else an engine with a huge compressor stall in progress!!

Could it be possible that the whole engine is not shown?! It certainly looks like the "heat" is coming from the exhaust to me, but hey, I`m only an eng....! Why would the spinner (if it was wrong) be protruding past the lip of the nacelle?? Possibly to upset the airflow in anything other than level flight? (tongue in cheek!)

As far as I can see the nacelle is not fitted.

you don't think that it is just a graphic .. put together by a graphic artist who doesn't know too much in the way of specifics .. for whatever document heading ... ?

and it does look sort of eye catching ...

From the number of bolt holes around the inlet lip and the number and angle of the blades I would say its the power turbine module of a jet engine which would make the Jetheat caption correct, as for the pipework I'm not sure. Perhaps the ITT probe harness drawn wrongly?

[anawanahuanana]

Tor,

You`re absolutely correct of course! Can you tell that I wrote my entry, then went back and looked at the picture, only to think "oops!". Sorry `bout the lash up!

[Checkboard]

Looks to me like an RB211 core, with the fan, shroud, accessories and low pressure compressor missing on the left hand side, and the flow shown correctly.

[Jetheat]

Checkboard, you've hit the nail on the head,

Well Done!

CHEAT

I'll have to disagree.

Take a look at this picture (from Rolls-Royce's website)



The image shows the engine from the front and left side. As I see it your picture is from the front righthand side.

If I'm correct your jetheat is definately going the wrong way. Of course I stand to be corrected

This might give you a better idea - the pic isn't too big, I hope!

[Tor]

That image just proves my point ( )

[Jetheat]

Tor, Checkboards Image shows that my Picture stands correctly. The cone is next to the Turbine therefore showing correct flow.

However, I don't know about the engine you pulled up.

[Tor]

I guess my last post was meant to be ironic

Should I have used a " " instead?

Anyway, I guess Checkboard delivered the final evidence.

Next topic!

[SchmiteGoBust]

Checkboard and Jetheat, I reckon you've both got it. I think it's an RB211-535E4 without the CNA and compressor part of the engine shown. The rear engine mount gives it away...possibly anyhow!!!!
