swimmer25k Posted August 25, 2017 Share Posted August 25, 2017 I've been working on a NASA 1/48 jet collection for a while and need some advice. So far I've got a SR-71 LASRE, F-104N, YF-12, and HL-10 either finished or on the way. I've got markings and kits for F-18, U-2 (different variants), F-106, F-102, and a few others. No model has been done of the F-15 ACTIVE, so I'm interested in being the first kid on my block to have one. Much of the conversion and modification of a stock F-15D (I'll probably go with a Great Wall kit) is straightforward except for the markings and afterburners. Artwork and printing for decals will be outsourced, which leaves the nozzles. The rectangular nozzles will be too much of a hassle, so the round ones could be the way to go. I don't know much about them and haven't found any good resources on them. In general, are they just PW F-100s with the different actuators, or completely new and different? Secondly, any suggestions (books, magazines, website) where to find good research? Thanks, Chris Quote Link to post Share on other sites

(A very lame excuse since I just bought a KP hi-grade Su-25UBK today). I'm a big fan of NASA markings, however, the black and yellow XL doesn't quite do it for me. Not that it matters a bunch. What resin is available for the Skunk kit? I typically like to add a resin/PE cockpit and exhaust as a minimum. Any idea if aftermarket for Kinetic F-16s would fit this kit?

X-Plane Fan Posted August 26, 2017 Share Posted August 26, 2017 The axisymmetric nozzles used on the F-15 ACTIVE (also known as pitch/yaw balance beam nozzles) had a very unique look to them. When parked they would also relax into a slight downward position. Tony Quote Link to post Share on other sites
BoeingDriver Posted August 27, 2017 Share Posted August 27, 2017 What are you going to use for the canards? I heard in the past that those are 18 stabs. Quote Link to post Share on other sites
swimmer25k Posted August 27, 2017 Author Share Posted August 27, 2017 They are F-18 stabs. I'll try to find an old Monogram or derelict Hornet kit. Quote Link to post Share on other sites
f86esabre Posted September 2, 2017 Share Posted September 2, 2017 Did you know that Hasegawa is releasing this aircraft in 1/72? I bet they will do a 1/48 also. CLICK TO OPEN EXPANDED VIEW HASEGAWA HASEGAWA 02251 NASA F-15 ACTIVE/IFCS 1/72 SCALE KIT Quote Link to post Share on other sites
Hoops Posted September 2, 2017 Share Posted September 2, 2017 What I like is that the Hasegawa kit seems to have included just about all of the different tail flashes and marking options, even those that that can't be built right out of the box. That way if somebody is enterprising enough, they can build just about any iteration of the aircraft with the markings in the box. Cheers! Hoops Quote Link to post Share on other sites
swimmer25k Posted September 2, 2017 Author Share Posted September 2, 2017 That's awesome. I'll definitely scoop up the 1/72 kit to use as a reference. I would like to use the Great Wall kit. It fits so much easier than the Hasegawa kit with a the awful wingroot seam. Please update us if you score some intel on its availability. Chris Quote Link to post Share on other sites
Hoops Posted September 3, 2017 Share Posted September 3, 2017 I do have a few pictures culled from basic good searches, but does anybody know where I can find good images of the 2D Thrust Vectoring/Reversing nozzles from the STOL/MTD iteration of this aircraft? Cheers, and thanks! Hoops Quote Link to post Share on other sites

catfan Posted September 4, 2017 Share Posted September 4, 2017 are there any walk around photos of the ACTIVE F-15? like the cockpit? Quote Link to post Share on other sites

Hoops Posted September 4, 2017 Share Posted September 4, 2017 Whoa! Those photos would help a lot, would you be able to share the rest somehow? Cheers, Hoops Quote Link to post Share on other sites
habu2 Posted September 4, 2017 Share Posted September 4, 2017 I did not know they put what looks like an E-model cockpit in the ACTIVE - including the HUD. Looks like only the front center MFD location is different... Quote Link to post Share on other sites

Kit also has the large production speed brake not the smaller version on the pre-production airframes which includes 71290 Edited September 4, 2017 by habu2 Quote Link to post Share on other sites

arnobiz Posted November 17, 2021 Share Posted November 17, 2021 Picking this up a few years later, would anyone have clear schematics explaning the nozzle mechanism? I'd like to make these nozzles but I can't quite see if the vectoring mechanism is obtained by playing with the petals alone or if the whole nozzle is moved at its root Thanks, Arnaud Quote Link to post Share on other sites

Hoops Posted November 17, 2021 Share Posted November 17, 2021 As I was intrigued by 3D nozzles, here is a engineering report from NASA: https://www.nasa.gov/centers/dryden/pdf/89247main_setp_d6.pdf A brief scan if you look under "ACTIVE Propulsion System Description." It looks to me that there is a "sync ring" buried inside the nozzle that deflects, and then the petals are aligned appropriately to provide the proper convergent/divergent nozzle to respond the power requirements. This photo shows the two nozzles in different states of deflection. The nozzle as a whole does not appear to be moved at the root, and the "sync ring" is hidden behind the braces/supports on the exterior of the nozzle. From a modelling perspective, I think manipulating the petals alone would be the best description. Cheers, Hoops Quote Link to post Share on other sites
arnobiz Posted November 18, 2021 Share Posted November 18, 2021 Thank you Hoops! The 2D nozzles are ready, I'm now considering the 3D nozzles so your explanations are spot on 👍 Quote Link to post Share on other sites
