Boeing Fighter Studies, 1970s to ATF

Much more interesting is this very unusually shaped ATF design, the Model 908-833. Its particularity is to use the the on-board inert gas generation system or OBIGGS.

(OBIGGS) processes engine bleed air into a nitrogen rich gas suitable for fuel tank inerting. Since the inert gas is produced during aircraft operation, the logistics problems of resupply vanish. Furthermore, the OBIGGS has weight and maintenance advantages over the foam system. (...)

The objective of this study was to develop a prototype development plan for installing the best choice OBIGGS in an Advanced Tactical Fiqhter (ATF). The best choice OBIGGS was based on detailed studies of inert qas requirements for AIF missions and trade-off studies to arrive at the best systcm preliminary desiqn. Detailed specifications were defined for' the best choice OBIGGS and life cycle cost studies were conducted to compare this OBIGGS with other fuel tank fire protection techniques.

Interestingly the basic model number "908" goes back to the LightWeight Fighter (LWF) competitions of the early 1970s, so it's interesting that it was reused here for a mid-1980s project (I really hope that one day we can understand the Boeing logic in designating their projects...).

Wow, thanks Quellish! I've wanted that info for a long time. Especially with all of the great cross sections and details. :)
 
Regarding the Model 987, has anyone found the report covering phase I, which is the development of the layout? The paper Quellish posted is for phase III. The reason I ask is the paper states that the standard layout was the four advanced air to ground weapons you see on the bottom of the fuselage, a 25mm cannon and two SRAAMs. I've not seen any indication of where the cannon is located or where the SRAAMs would be carried. At this point I'm assuming the SRAAMs would be carried externally on wing pylons outboard of the main gear, but I've been unable to find any evidence, so I just thought I would ask.

I'm still searching, if I find anything I'll post it.

The vehicle shown in this image, based on the text, is the Grumman design, not Boeing's.
 
Here a drawing of a Boeing Interceptor for the ATF program.
The picture caption mentions, that this project should weigh less than 22,700 kg and cost less than $40m (1985).


According to this topic, this drawing was posted in b/w before and its designation is Boeing 985-430 Supersonic Interceptor.

Re: Boeing Fighter Model

Obviously an iteration of the Model 818 TFX, but why a single-seater? I don't think I'd seen this before.

To me, it looks more like a design for the 1970's ATF super cruise strike fighter program.
 
Re: Boeing Fighter Model

Hmmm. Maybe they used their TFX entry as a starting point?

Re: Boeing Fighter Model

I think that's Boeing Model 818 for the TFX what became the F-111

Boeing proposed for 818 and 818Navy Different cockpits

I think Scott is right, Michel, as proved by the image he shared. It is indeed an ATS proposal, but strongly influenced by one of their earlier TFX designs. Thanks!

Re: Boeing Fighter Model

One moment Skyblazer and hesham

i just realized something, How many pilots are in USAF TFX: One or Two ?
since this is one seater and most USAF TFX models show two pilots cockpits

and by the way, what was Boeing proposal for FX that became F-15?

People on this forum do not read what's written today, it seems... ::)

I said that it LOOKED like TFX but was surprised to see a TFX with only one seat, as indeed the TFX was a two-seater.
To which sferrin rightly replied that the ATS (early ATF) proposal by Boeing was exactly like the model, even providing an original painting of that project.
End of story! Why continue to question when we have an image of the Boeing ATS that matches the model perfectly?! ???

As for your question, I do not know of any Boeing proposal for FX, so I couldn't give you the Model number. However I'm sure they must have worked on that proposal at some point, so most likely someone like Paul or Scott would know.

Given the possibility SST biz jets, the USAF Century series developers should look at past concepts where a single airframe could be used for fighter, tactical bomber, transport, and even cargo hauler roles .
