Quixote74 Posted September 19 Share Posted September 19 In the interest of completeness, below is an Israeli F-15I which has Pratt F100 engines with "feathers" (apologies for poor resolution): You may also notice the darker color: select varieties of the F-100 have carbon composite outer nozzles, giving them a metallic black finish instead of the more usual natural metal shade (AFAIK the shapes are the same). Certain F-16 operators, Korea being one example, used the same composite nozzles on their F100-powered batch of Vipers. Counting feathers as a way to differentiate the (non-featherless) P&W engines from the GE F110s seems rather cumbersome to me (and requires close/clear images of the hot end). I've always found the overall shapes of the nozzles distinct from each other: the Pratts have a conventional truncated cone shape with the outer edges in straight (converging) lines, whereas the GEs have a subtle but noticeable curvature to the outer "feathers." Also had this image in my files, which shows an F100 partial cutaway - note the top 'feathers' are still in place, with the lower portion removed as in the 'featherless' exhausts now seen more often than not.

I believe composite feathers are unique to the PW-100-229 version Quote Link to post Share on other sites
Hoops Posted September 20 Share Posted September 20 To add some clarity, there following versions of the F-15 have the GE engine: F-15K Korea F-15SG Singapore F-15SA Saudi Arabia (To make it more confusing, the F-15S purchased in the 1990s have also been upgraded with GE engines) F-15EX USA F-15QA Qatar An in another move that will make things confusing in the future, Israel has a contract to purchase 25 new build F-15IA versions based on the EX, as well as upgrading 25 F-15Is. I do not know if this means they will also get GE engines, but I would say there's a good chance that they do. Cheers, Hoops Quote Link to post Share on other sites
Raptor.777 Posted September 22 Author Share Posted September 22 Here's another ? Do the Isreali F-15D, I and what other variants they use , use the GPS domes like our F-15s do? Thanks Jeff Quote Link to post Share on other sites

Thanks Jeff The Israeli Cs and Ds do now, but I believe they would all be retrofits (the F-15I, Israel's Strike Eagle derivative, had them from the production line). Some google-fu didn't turn up any definitive images or info about GPS on the A/B models. The photo linked here shows a D with the GPS "pimple" just visible on the starboard dorsal panel, aft of the gun vent. This one also has the much larger "R2D2" dome antenna added behind the cockpit, speculated to house new SATCOM equipment. The same antenna has also been added to at least some F-15Is.

Niels Posted September 24 Share Posted September 24 The GWH F-15I have it. Part W27, from the sprues with the CFT's. Quote Link to post Share on other sites

In 1:72 GWH is the only source I'm aware of, but in a somewhat ironic coincidence a 1:35 WWII German helmet is a pretty close approximation. Quote Link to post Share on other sites
