Here are two pictures of the N-102 mockup:

Northrop N-102 Fang Project
Hugh W Cowin
Air Pictorial

X-Fighters
Steve Pace
Motorbooks


Towards the end of 1952, Northrop started work on a lightweight Mach 2 interceptor as a private venture. A two seater trainer variant was also studied. The N-102 design requirements were similar to those of contemporary Lockheed TDN CL-246. CL-246 also was submitted as an unsolicited proposal to USAF (November 1952) but its seductiveness was enough for them to invent a GOR calling for a new lightweight fighter to replace the F-100 (Weapon System 303A).
CL-246 then competed to another proposals and was selected for series production as the F-104 Starfighter.
Unfortunately, I have no info about that rival designs. It seems that Republic design was identified as Model AP-55.

According to Mr Cowin, the Fang was no submitted to WS 303A. It was simple dropped by Northop's directive Tom Jones in favour of the far cheaper N-156 by the close of 1954.

May be Evan can add some additional information...

I think Republic's AP-55 design was based on their XF-91 Thunderceptor, only with a solid radar nose and NACA-style flush intakes on the fuselage sides ahead of the wing.

Thanks a lot for the info Sentinel.

Estimated max speed for the Republic AP-31 (XF-91) was Mach 1,5. If AP-55 was to be a Mach 2 fighter if had to be aerodimically refined (area ruled fuselage). The powerplant would have been a single J79?

It looks like it very well could be.  That one is going to be on my "must buy" list.

Thanks Deino ;)

I'm going to buy the book. I want to know more about the Bell jet fighter

That's what I understand, it was the first or one of the first light fighter designs to use the J79 engine. Ultimately the requirements that the N-102 was designed to meet evolved to result in Lockheed's F-104 Starfighter if I remember right.

Thanks again, Sentinel

An AP-31 derivative with a more powerful engine could have reach Mach 2 performance..with this data, I think I can try to produce a drawing of the hypotetical Republic AP-55

The one on the cover isn't a Bell design. It was the BDR patented by Interstate Aircraft.

http://www.designation-systems.net/dusrm/app1/bdr.html

All the patents they mention I have. The Twin Liberator is a pretty neato design but was patented by Just Some Guy, not Convair, so it stood effectively no chance of being built.

The "McDonnell design contemporary with and similar to the XP-67 Moonbat, except being of pusher configuration"  is actually a design patent for the McDonnell Model 1.

Are there any schematics, drawings, or photos showing the landing gear configuration of the N-102?

The N-102 mockup - in US Air Force markings - didn't have a landing gear, but the drawings indicate that the nose gear was mounted ahead of the ventral intake.  This arrangement would seem to partially obstruct airflow to the engine during takeoff and landing, but it does provide for a long and stable wheelbase - important because the N-102 Fang was also proposed for the Navy as a carrier based fighter.

Why, yes... yes, there are.
