VH-OJA to ALBION PARK - Discussion and Photo Thread

[Michael Mak]

I went on the HARS museum tour last Tuesday and took some photos on OJA, it might answer some questions that you guys have:

I think that's a special nacelle, looking at a close up of the RB211 on the 747-400 their is no split down it where it can be detached. I believe it's a 747 engine, the ex-BA 767's had RR RB211-524 engines same as the 747 but I don't know if they could be interchanged. Here's an image from Perth with the fifth pod which is for a 747 which broke down enroute from SYD-JNB: http://i677.photobucket.com/albums/v...9/5thpod-1.jpg It looks very different but I think it's due to the blades being removed and a special fitting over it (nose cowl is a lot thicker).

767 and 747 Rolls Royce engines are exactly the same except for three parts, none of which you would be able to see with the engine fitted to the strut.
The front bit, called a nose cowl, on the V-Pod is a normal nose cowl. There is a cover that is placed on the leading edge of the nose cowl for aerodynamic purposes.
The next cowls back are called fan cowls and are also only used for the V-Pod, but they are essentially the same as the others on the aircraft. The cowl behind that is called the INA (Integrated Nozzle Assembly) and is part of the engine itself.
The strut, the bit that attaches the engine to the wing is only used for the V-Pod. If you look at Michael Mak's photos there is a picture of the fittings in the wing where they attach the rear of the strut. The front is attached to the leading edge spar via a "banana link"

The fan blades are removed and a "bung" is placed in the inlet. This prevents the engine from turning the entire time it is in the air. A small amount of air is allowed to pass through the core of the engine, but not much due to the "bung". The blades travel in individual boxes in the hold of the aircraft.
Hope this helps.

Some photos. If it works!

Thanks very much for the info guys - fascinating insight!

Thanks Grahame, bet that would be interesting on a pax flight - pilot would explain the extra engine, no?

[Rowan McKeever]

TBH I probably would've spent the whole flight racking my brains wondering where QF got the red cowling on #1!

[Fred C]

The red cowl would have been from when that engine was fitted to Wunala Dreaming when it was VH-OJB! They didn't have the opportunity to paint it grey.

Probably, the presence of the fifth is noted on the flight plan for the benefit of watching eyes.
