      I am planning to build either a Scandinavian or Eastern Airbus 300. Are both of them GE engined? I understand those the ones included in the Airfix kit? I am planning to buy the Braz resin ones... Dont know if it is worth it though...

      If I am not mistaken Scandinavian used PW engines. The kit supplied engines are GE, which Eastern used. Braz has GE and PW engines for the A300-600(R), the PW for Eastern's A300B's are a bit different I believe.

      Hi all,

      Yes, the 4 SAS A300's used PW engines.

      Happy modelling,

      The Eastern Air Lines Inc A300B4-2C, A300B4-103, A300B4-203 & A300B2-203 all used versions of the General Electric CF6-50C engine (as provided in the Airfix kit).

      The SAS/Conair et al A300B2-320, the Iberia A300B4-120, the China Air Lines Ltd A300B4-220 & the Garuda Indonesian Airways A300B4-220 all used the Pratt & Whitney JT9D-59 engine (with the long chord cowling, I don't believe there is an aftermarket conversion part available for this specific engine).

      BRAZ provides Pratt & Whitney JT9D-7R engines which are only applicable to Saudia A300-620, Kuwait Airways A300-620C & Abu Dhabi Government A300-620C......

      Indeed, without question, the Airfix A300 kit engines appear to resemble GEs rather than PWs...although IMHO (like the Revell 767) the kit engines could arguably be said to represent neither. If one is looking for accurate injection molded A300B4 GE engines, Hasegawa's 1:200 kit is 'the only way to go.'

      Sad to say, 1:144 overall is poorly represented in the category of injection molded kits depicting first-generation widebody types. Once considered trying to modify/convert the Airfix A300 kit engines to reasonably resemble PWs (for a SAS build)...only to conclude it would be altogether impractical if not well nigh impossible to accomplish at my Airliner Modeling 301 skill level.

      Thanks for all the info. So I should go with the PW4000 engines then? or the Braz Jt-9d... I really like the Sas classic style

      No, I don't think so. There are no after-market engines for those early P&Ws.

      Braz has made the JT9D59 engines ( I Have a set ) and a quick search on here also confirms this:

      Ah, I stand corrected. Thanks Ray. I thought they were for the A300-600s.

      Thanks again.
      For my untrained eye they all look the same. What should I notice between these engines?







      Are the differences in the exhaust section? To me all the cownlings look the same.

      I think the cowling is different, but not sure 100%. The exhaust section is shorter and there is no bullet.

      I stand corrected, BRAZ have saved the day......


      The CF6 engine is thinner & longer because it has thinner & longer compressor sections (inherited from the TF-39 engine)......

      The JT9D engine as applied to the A300B is shorter & fatter, but has a longer fan duct (because there are more accessories mounted to the fan casing than there are on the Boeing 747's JT9D short fan duct)......

      One of the major differences is the lack of pointy exhaust cone on the PW's as circled in the Iberia photo below, compared with the GE's as shown on the Iran Air:

      Great help. There's a world about engines.
      I'm taking the Braz Jt9, and F-Decal SAS livery. It's laser, but it's the only game in town.

      Maybe we could have a Sticky section about engines? It's always tricky and it is easy to make mistakes about them when building.

      Good idea, there are lots of similar-looking engines and mounts that are different when you start paying attention to them. I'll start writing up a guide (maybe on my long flight to Europe this weekend), but I'll need help for some of the older Airbii, among others.

      Just come across this old topic. Reason? Was comparing Hasegawa P&W and GE engines on the DC-10 to use as a guide for an A300 build. However, the Hasegawa (while right in terms of shape) turned out to be a little wrong in terms of dimensions (or perhaps more correctly, scale)... The truth was in a Douglas modelmaker's drawing of the GE and P&W powered DC-10.

      Here, then, is my rough guide on the A300B installation (the A300-600 is entirely different):

      - the P&W engine appears to ride marginally higher (10cm/4in at the top of the intake, 15-16cm/6in at the bottom of the intake). Its thrust line is identical to the much more widely used GE engine.

      - The P&W engine is also mounted marginally further back (20cm/8in at the front).

      - The P&W engine's forebody extends 60cm/24 in further back than the GE engine, and its afterbody is 27cm/11 in further back than the GE engine afterbody. The GE engine, however, has a 'spike' (turbine or shaft fairing) protruding from its extreme rear, which puts its rear end 75cm/30in further back than the P&W engine.

      - The P&W engine looks beefier since it is shorter; its nearest visual equivalent is the RB.211 on the L-1011 or RR powered 747-200. The GE engine looks smaller since it is sleeker and longer. But the forebody diameters are very similar and the GE engine is actually marginally the fatter of the two, despite a marginally narrower intake.

      All figures above are approximate.

      Trust of help!

      ---

      Edit: the pylons are also somewhat different. The P&W engine features a small forward extension tacked onto the upper forward end of the pylon -- like a tiny forefather of the marked 777 'caps.' The pylons' rear ends differ, too, with different skinning and access hatches, and even shapes. There are two drains (pipes extending horizontally backwards from the pylons' trailing edges -- for spraying chemtrails, of course ) on the GE engine and one on the P&W.

      I'd attach a sketch, but the procedure is too involved and I have little time at the moment. Maybe later...

      ---

      Here are two images, each worth a thousand words, of course. Top is the DC-10 installation. The A300B was identical, except for the aft part of the pylon. Below is my rough of the A300B installation. The point of alignment between the two (in both sketches -- DC-10 and A300) is the wing leading edge-to-pylon junction. None of this is any too scientific, as the DC-10 drawings (what I have of them) appear to be 1971-ish DC-10-10 vintage, with butterfly-tailed CF6s and the DC-10-40 is still designated "DC-10-20"... Oh, and the A300 sketch shows the JT9 top, facing a CF6, and a CF6 bottom...

      If you bother to wownload them, you might want to know that each pixel is equal to 1 centimetre. So if you want to print them, set the resolution to 144 pixels to the centimetre for 1/144 scale, 200 for 1/200 scale, 125 for 1/125 scale, etc:





      This is just a sketch. I would welcome some scale diagrams and if anyone has them, I'd be delighted to do you all a better one

      I am not good with engine Ids however I am taking the engines from a Revell Baluga kit and with a little.

      Modification to the exhaust installing them on my Pan Am A310. Frsin A300B AA kit just arrived using those same engines.

      Am I committing a mortal sin here?

      Doubt if using Beluga engines on an A310 quite makes it into the mortal sin stakes, but it sounds like fun! If memory serves me right (and it often fails me these days...), they are a tad on the biggish side. Making an A310 (or an A300-600 for that matter) is largely outside the scope of this thread, however. Different animal, different engines, different pylons -- the works...

      I would personally just buy a set of BraZ conversion PW400's/JT9D's depending on if you're doing a -200 or -300 A310. To a trained eye the GE's are completely different in shape and size to the PW's. The Revell ones are too fat to begin with and will require a lot of work to achieve the slender, narrow appearance of a PW.

      Having had somewhat similar thoughts once upon a time, I learned the hard way the Revell Beluga engines are way too large for A310 applications. My current plan, if I ever get around to building my Revell A310 as a Pratt-powered aircraft, is to adapt a spare set of the not-quite-Pratt/not-quite-GE engines from a Revell 767 into something that looks acceptable.

      Just received a set of A300B Pratt & Whitney engines (plus a set of Pratt & Whitney engines for the A310-300) from Ivo Braghin of Braz. They are wonderfully accurate and well cast in mid-grey resin without ay bubbles or deformations. I hope to steal a moment later today to post some photos into the database...
