Hi everyone, I am new to here... And I was looking for a particular aircraft- Boeing 707. But, I am looking at this aircraft www.airliners.net/photo/Boeing-707-3L6B/1371883/L/ Notice the engines- they are DC-8 engines. As I couldn't find it here, and I do not know how to do that texture, can I request HJG's team to change the B707-300B engines to DC-8's? Your truly

I've just fixed your image link .... and "NO" .... those aren't DC8-62/63 type engines .... and we do have this model available here at HJG (in B707-320B ADVC and B707-320C form) albeit a lot of folk probably don't realize it. I believe what you're looking at there are a Stage 3 hush kit modification developed during the late 1990's and applied to only a few aircraft .... like this one .... You'll find this aircraft on the HJG "B707-320B ADVC" downloads page as follows .... LOWA LTD 2006 - N88ZL - 707-330B Textures by Gary Carlson Last Updated: 14 Jul 2006 This texture uses the "HK3" model in our B707-320B ADVC Aircraft Base Pack. And another one like it on the HJG "B707-320C" downloads page as follows .... AIR MEMPHIS 2004 - SU-AVZ - 707-336C Textures by Gary Carlson Last Updated: 12 Dec 2006 This texture uses the "HK3" model in our B707-320C Aircraft Base Pack. Hope that helps clear up any confusion !

Another question- Sorry if that is related to the answer above, but I would like to clarify my doubts. The Hush Kit (Stage III) was one thing. But Pratt & Whitney recently have a re-engining program. I quote from wikipedia- The JT8D-217 and -219 engine(s) were tested in 2001 and were deemed suitable replacements for the old TF33 engines on military and commercial aircraft as part of the Super 27 re-engining program. The updated engines offer reduced (Stage-3) noise compliance standards without the need for hush kits, enhanced short field performance, steeper and faster climb rates with roughly a 10% reduction in fuel burn for extended range. Pratt & Whitney, in a joint venture with Seven Q Seven (SQS) and Omega Air, has developed the JT8D-219 as a re-engine powerplant for Boeing 707-based aircraft.[2] Northrop Grumman has the -219 to re-engine the United States Air Force’s fleet of 19 Joint Surveillance Target Attack Radar System (E-8 Joint STARS) aircraft, which will allow the JSTARS more time on station due to the engine's greater fuel efficiency. NATO also plans to re-engine their fleet of E-3 Sentry AWACS aircraft. The -219 is publicized as being half the cost of the competing 707 re-engine powerplant, the CFM-56.[2] There have been on and off again discussions of using the engine for the B-52H, which is programmed for use until 2040. A photo- en.wikipedia.org/wiki/Image:Pratt-707re-N707HE-071126-25-16.jpgAre they the same?

No .... those powerplants are actually quite different !
The P&W JT8D-217 is a completly different and "super quiet" engine .... similar I believe to those attached to late model MD90's and B717's,
I think the nacelle shape is similar though to the P&W JT3D S3HK equipped version we currently offer .... but .... I stand to be corrected there.
At this time we don't feature a P&W JT8D powered 3D model.

The JT8D-200 is actually quite loud. Based on the JT8Ds used on 727s and DC-9s, the 200 engine features a larger diameter fan and a few other improvements. While it is quieter than the older models, it is still one of the loudest engines out there on commercial aircraft, used mostly on MD-80s. MD-90s are powered by the much quieter IAE V2500, while 717s are powered by the even quieter BR715 engine. While very similar, there are a few minor differences between the JT8D-200 nacelle and the JT3D S3HK that was applied to aircraft like N88ZL.

That's interesting Nick .... because whilst researching for my recent B707 feature most of the little JT8D-217 information I came across promoted these new powerplants as being "extremly quiet".
We are talking about the newer more recent JT8D-217 aren't we .... rather than the earlier JT8D series which typically powered 727-100/200, B737-100/200, and DC9 series aircraft ?
I'm pretty sure the -217 is the later more quiet powerplant.

CLARIFICATION ....
Sorry .... my fault .... it's the "P&W JT8D-219" powerplant version I should have concenbtrated my reference upon .... though I suspect the same still applies to the -217 as well ....

I wouldn't doubt that a circa 1980 or so advertisement from Pratt and Whitney would describe the JT8D-200 engines as extremely quiet, as they offer a considerable noise drop from the early JT8D-1 to -19R series or JT3 engines. The higher thrust JT8D-219s are actually louder than the JT8D-209 and -217 models.
JT9D-200 engines are Stage III compliant, but not by much. The BR715s on the 717, by comparison, exceed even the proposed Stage IV noise levels.

Ah. So they are different. The source says that the engines will re-engine the E-8 J-Star and CFM? It says the P&W JT8D-219 re-engine the United States Air Force’s fleet of 19 Joint Surveillance Target Attack Radar System (E-8 Joint STARS) aircraft, which will allow the JSTARS more time on station due to the engine's greater fuel efficiency. NATO also plans to re-engine their fleet of E-3 Sentry AWACS aircraft. The -219 is publicized as being half the cost of the competing 707 re-engine powerplant,the CFM 56 The P&W JT8D-219 is actually half the cost of CFM 56? It will be great if I can find the B707 with the re-engine P&W JT8D-219.

So far as I'm aware it doesn't yet exist for FS .... the closest to it is our HK3 B707-320B/C models.
I'm not sure what Gary CARLSON's Boeing modelling plans are at the moment either.
Nick .... I've never seen or heard anything down here equipped with those P&W JT8D-217 or 219 series engines, so, I trust you're view regarding them.

The first plane to be equipped with 219 engines is one of the Omega air B707. E-8 J-Star and NATO B707 will have 219 engines in the future.

We do have the/an OMEGA AIR B707-320B represented here .... see our "B707-320B ADVC" downloads section .... .... only in the earlier P&W JT3D series fanjet configuration though and without refuelling probes too. "IF" you wanted scratch build a visual representation that's "a little" more accurate if not totally authentic .... then you should be able to achieve this as follows .... - change the model assignment in the OMEGA CFG data to read MODEL=HK3 - you will then also be obliged to change both night and day engine textures too .... I recommend using the natural metal engine textures from our AIR MEMPHIS B707-320C (use the Gary CARLSON texture version only whish is for the HK3 model) in the absence of anything else/better .... for the moment ! That should all work fine .... as an interim solution. "IF" you or anyone else is successful in accordance with my above suggestions then please post a couple of FS images here. Mark C AKL/NZ
