Northrop / McDonnell Douglas ATF - YF-23 and EMD F-23

Is this sure the next APR review has the two F-23 models? I was browsing unwanted blog and Scott didn't speak of it in its APR update post.

Absolutely! And that's because the F-23 is American. "Gray" is spelled (spelt) "GREY" in British English.

Generally, gray is the name given to the cool, blue based, variations of the color and grey is the name given to warm, brown based, variations of the color.

What're you, a girl? "Gray" is "somewhere between black and white."

Pfff.

Are you quite sure this is a generalized usage? Are most people in the US aware of there being two spellings, anyway?? Your description could be of a local usage, perhaps? Or related to a certain trade? I don't know, never heard it before visiting this forum.
All I can say is that "GREY" is in use in a large part of the world, and "GRAY" just doesn't exist in British English. I was always told at school and university it was the American spelling of the word, not a subtle variation of its tones.

No, I'm the guy doing the F-23 profiles (Yes, I'm working on them as I type, except for the actual typing part. A four day weekend means profile work time, not shopping!) who wants them correct ;) ; and I also do aircraft textures for 3D models for MSFS and I don't hear the the end of it if the correct colors aren't used. If you think modelers are bad when it comes to rivet counting, you should encounter some of the flight simmers I've seen online. ;D

Ah scott, can you please specify the F-23 content?

Is this production F-23 desktop models or different planes based on the F-23 (so outside the ATF program)?

Clearly, in the APR issue, will we see desktop model of what would be the production F-23 or different program?

thank you

P.S: i too love cats.

From the "iron bird" model?

I'm not sure if it has any connection to YF-23...check geometry.

Yeah, i noticed it. I looked at the only picture i have of the iron bird (the pic taken in 90, in workshop) and the nose doesn't match. So it is some kind of fake i guess.

Not sure if these pictures are posted, although they are not any special, any picture of YF-23 is gold worth to me. :p

Such a shame that such a nice bird has been through so much suffering... :(

PS: And current status. :)

I'm pleased to say that Grey Ghost (aka Spider, PAV-02) is now reassembled and on display at the Western Museum of Flight. Beautiful aircraft and it was fun to work on (I was one of the guys that put it back together).Russ

Beside putting it together, did you guys do anything else to it?

Heya, Donage99!

Sorry about the late reply!

Nothing has been done to it save for cleaning trash out of it. The plane is, for the most part, in really good shape... a plus for it's composite construction! There are a few aluminum access panels that are suffering corrosion, especially the air refueling door topside. The canopy and windscreen are in poor shape, the acrylic being stress cracked and degraded. The windscreen was painted over at some point during NG displaying it. I've talked with someone that said the canopy can be polished out so it looks decent, this is potentially on the future "to-do" list. Other than that, the plane can use a good scrubbing... this being a logistical problem as the plane is bigger than either of the two wash racks at the airport!

We have all the typical non-profit museum problems: never enough money, lack of personnel / expertise, etc. We're forming up a maintenance / restoration team, but are going to be limited to what we can do until we move into new facilities.

in late 00s, on several AIAA conferences (2007 AIAA Atmospheric Flight Mechanics Conference, AIAA Guidance, Navigation and Control Conference) - Bob Sandusky was presenting a one hour lecture, titled “Designing a Fighter Jet - A Case Study of the YF-23A Advanced Tactical Fighter Prototype”

was anyone lucky to attend?

Is there any date for that new issue with F23 models? On what are they based? The latest technical drawings?

Perhaps I missed it, but has this issue already come out?

Russ, I'm sure you could find a few volunteers on this forum to help with a good washing ;)

No,

I'm still working on the artwork, which has been difficult, since I'm working my butt off at my day job. But it is progressing, slowly but surely.

Ok thanks. Looking forward to it.
 
I don't think this was posted previously:

Another YF-23 walkaround

That's a nice surprise. Thanks supacruze! :eek: but it's such a waste of internal space if true :( I so hope they had a better idea for the production version
 
Lovely Tony Chong's photo
about quarter of century after first sketches made, she still out of this world

In the drawing the missiles look like AIM-120As, which take up more space than AIM-120Cs. However, the development of the C was still classified at the time, although Lockheed and Northrop knew it existed. So, any Northrop illustrations or unclassified technical info (such as the pilot manual) would be based around and refer to only the A.

I agree. Best-looking modern fighter there ever was! The new PAK-FA and J-10 come close, but the F-23 is still the top!
 
From all the research I've done, I'm totally convinced the YF-23 weapons bay was never meant to be a full-capacity unit; they were just trying to make a bare-bones flying testbed... and this is where so many observers go wrong. They don't understand that the bay was not designed to accomodate the full service requirement. That was done in the F-23A, as we now all know. There's more details on my new site.
 
dear all,
i've just came to USAF Museum in Ohio and saddly the YF-23 is not longer on a public site.
they don't know when is going to be back.
very sad thing

YF-23 was never at *public* part of USAFM

Presidential/R&D Requirements
The Presidential and Research & Development Galleries, located on the controlled-access portion of Wright-Patterson Air Force Base, are accessible using the shuttle bus service from the main museum complex. This service is offered on a first-come, first-served basis. Sign up early as buses fill up quickly!
Shuttle buses are not handicapped accessible. Individuals requiring special assistance should contact the museum's Operations Division in advance at (937) 255-3286 to arrange transportation.
Military and Department of Defense civilians with government ID may use their private vehicle to visit the Presidential and R&D Galleries.

Note: A current government-issued photo ID (i.e. state ID or driver's license) is required for citizens of the U.S. and U.S. territories over age 18. All foreign visitors must present an original passport (a NEXUS card is an acceptable form of ID for Canadian citizens) or a foreign enhanced driver's license. Those under age 18 must be escorted by an adult (one adult per two children); children are not required to produce identification when accompanying their parents.

Hours of Operation
The Presidential and R&D Galleries are now operating on the following schedule:
Bus departs museum at 10 a.m., 11 a.m., noon, 1 p.m., 2 p.m., 3 p.m. and 4 p.m. seven days a week.
Participants must attend a briefing 15 minutes before their bus departs the museum. For those with base access, the galleries will be open from 9:30 a.m. until 5 p.m. daily (use Gate 19B).
 
Sorry, that is what i meant.
The grey ghost is no longer at the R&D hangar.
They remove it "for restoration" and since it is not a usaf aircraft, it is not a priority
I told them, it should have been a fighter and it should be a priority.
They just smiled.

Still pretty good stuff to see, on both public and restricted areas, but no yf-23.

They said to have no idea how long it will take to have it on display again.
 
That's really weird. I saw it in July of 2009 (granted, that was a while ago, but it's not like it accumulates a lot of wear and tear) and it looked to be in great shape. I wonder why they decided to pull it? The "not a priority" bit does explain the significant amount of time it's taking to get the MiG-25 restored, at any rate! Maybe I need to get onto one of the R&D tours and see what's what.

I wonder then what those big white letters on PAV-1 engine nacelles should mean. those, you know - 'U.S. AIR FORCE'
 
All that means is that they prioritize the display of in-service types. Hence why the X-32 they've got is still being restored as well, and why they gave up the B-1A and YF-22 for a B-1B and F-22A.
 
Doesn't that defeat the purpose of an R&D hangar?
Having said that, when you look at the build quality of a new prototype relative to a new production aircraft, one can understand that they are a bit more challenging to keep in good shape over the years.
