Here is a couple of tail-pipes:

G'day Brian.
Eureka! Finally, something I recognise, well, I hope so...the Ikarus Type 452?...

Yes, Noyade is correct:ok: The Yugoslavian IKARUS 452. Your turn.

Thanks Brian.

Moving on....

Dassault Mystere IVN?

Heading off to work Ken. Not the Mystere. I tried to be clever. Turn it upside down...

Thanks Graeme. Here is a nice easy one:-

G'day Mel. I think our definitions of "easy" vary greatly! :)

First thought was that "thingy" at 6 o'clock was the front end of an arrester hook, say the Dassault Etendard, but I don't think it should be so close to the exhaust lip?
Second thought is the thingy is the break parachute fairing on possibly, the Repuplic Thunderstreak?

Question 1. Trying to education myself on anal aviation - if the tail-pipe doesn't have, as cutaways call them, a variable exhaust nozzle, then can I assume it doesn't have an afterburner?

Question 2. What gets more success when googling for these images...tail pipe, jet pipe, exhaust, jet exhaust, engine exhaust, exhaust nozzle,...etc...? I'm not having a whole lot of luck.

Is this a tail mounted jet? Something like the Piper PA-47 PiperJet?

Wow! Never seen that before.

Ken, is there a Plane-spotters graveyard anywhere? Where I can go and die?

Sorry chaps did not think it would be difficult, I thought it would be easy like the latest Avia Quiz :rolleyes:.
To answer your questions:-
Q.1 It does not have an afterburner.
Q.2 Possibly engine exhaust but it really depends as the quiz image may be taken from a general view of the aircraft during a walk around.

It is not a tail mounted jet such as the Piper PA-47 Piperjet.

This might help:-

Early low bypass turbofan with clamshell reverser mechanism underneath?

David. It certainly is an early turbofan engine with clamshell thrust reverser.

Soloviev D-30

In an Ilyushin Il-76?

Sorry Reg. Not the Soloviev D-30 in an Ilyushin Il-76.

Quick stabs...

Lockheed Starlifter?

A good stab Graeme. It is the Lockheed C141 Starlifter.
