Where's the logo gone from the SIA A380 engine?

 One of the more observant members of the team has noticed that the SIA logo has recently been removed from the engine of it's A380 aircraft:

First it was here:

 

And then gone:

 

Now this isn't just in these pictures, more examples have been seen of late! Does anybody know why this has happened?Is it just an oversight, or is it something else completely?

They are two different aircraft MSN 004 carries the logo and MSN 003 (9V-SKA) did carry the logo but it's been removed, i guess ready for delivery

 Thanks Goose, but why would it be removed for delivery, i'd imagine that SIA would want their logo everywhere over the livery?

Is there any chance there will be a Rolls-Royce logo there instead?

Perhaps it was to save fuel.

Boeing decided to not allow any logos on the Boeing 787 engines to save fuel.

The edge at the start of the logo may be small but it adds to turbulence and drag.

The change allowed Boeing to shape the engines for low-drag laminar flow to extend further back.

I forget the amount of the savings, but it is something like 1 liter per passenger per flight (or possibly more).

The savings on an existing design is probably less, but this might be the reason!

 That's interesting Mark, i never realised it caused that much in turbulence. Thanks for the info

Thanks Mark, I remember that, it's always been Boeings policy not to have large logo's on the engines..so i am guessing with the A380? that they were applied just for PR...heres a recent pic of a Singapore 777-200ER...no engine logo's

I am not sure what Singapores criteria is for putting their logo on their aircraft engines but i have seen some aircraft with them and others without them.

I find it strange that Boeing dont allow logos on engine cowlings as at the end of the day it is up to the airline not them. I guess they can recommend airlines dont do it but if the airline want to then thats up to them.

I prefer the engines with the decals; the one without looks ok, but just a little bare. QF's newly revised will include a logo on the engines; I would expect this to apply to all acft in the fleet.

 With regard to Boeing or Airbus objecting to decals, what do the engine manufacturers say? Most engines nowadays are painted (eg. the Wizz A320 phographed on the website today, or BA, UAL, TAM and others) ... how do manufacturers feel about this practice? Until about 1982, with the introduction of the 757/767, most engines were natural metal.

An answer of sorts from SIA:

Interesting reading the article as they say that logos dont appear on the other aircraft in the fleet. Yet i have seen photos recently of logos on the engine nacelles on some of their 777s.

From what I understand, the removal of engine logos across the SIA fleet is due to fengshui reasons, something about there only being 1 big SIA bird logo rather than many smaller ones. The recent re-numbering of numerous SIA flights is supposedly because of the same reason. SIA, being an Asian airline, believes that changing the fengshui will allow them to reap greater profits, especially with the arrival of this new behemoth into the SIA fleet.

Thanks for the info lammified, i never thought about that idea
