Hi,

http://www.flightglobal.com/pdfarchive/view/1978/1978%20-%200695.html

 

[overscan (PaulMM)]

Here's a late P.110 drawing showing how the P.110 evolved, via adopting the German TKF-90 engine intake position, to then become the ACA. It doesn't seem to have been noted before that EAP was originally "Experimental Aircraft Programme for the Agile Combat Aircraft", nor how the P.110 morphed into the ACA.

 

[overscan (PaulMM)]

Added decent quality photos to earlier post:

http://www.secretprojects.co.uk/forum/index.php/topic,169.msg37073.html#msg37073

Here are some more MBB studies from late 1970s. These are intake studies from the same AGARD Conference report.

 

[archipeppe]

I clearly remember to have seen that drawing and a photo (perhaps a German full scale mock-up related to ACA) in some Italian aeronautical monthly (Aerospazio Mese) back in 1982.

At that time it still existing ACA or have become Eurofighter 2000?

 

[overscan (PaulMM)]

As labelled, its a BAe study, P.110, but a late version which was converging to the ACA/EAP. P.110 was a private venture fighter designed in 1981/82 to a possible Saudi requirement. This is an early version, with side mounted intakes.

This?

 

[archipeppe]

This?

Perhaps, the photo was b/w taken at ILA and the mock-up had Luftwaffe markings....

Still no Luftwaffen markings, but another view of, what I think was the same mock-up
made by MBB, in Germany designated as TKF (Taktisches Kampfflugzeug).

Here it is, as you wrote no LW marking but the plane is it.
I recall the same plane with LW marking and light grey painting (or so it was a b/w photo).

Many thanks Jemiba.

Hi All -

A display model of the BA P110 available on EPay:

http://cgi.ebay.com/British-Aerospace-P110-Aircraft-Model-/160536684887?pt=LH_DefaultDomain_2&hash=item2560bb6957

Good sized model but a bit of a steep price....

Enjoy the Day! Mark

 

[overscan (PaulMM)]

Nice model, but overpriced perhaps?

[Tophe]

In the magazine Science & Vie Hors Série Aviation 1981-90 (of 1981), it is explained that the MBB-Dornier TKF was intended to replace German Phantoms and came from a Dornier study (single-engine on this one, drawing below)

Just a quick EAP question, looking at the aircrafts cockpit arrangement it looks like the cockpit was laid out with two seats in mind with plentiful space in the rear of the cockpit area, was this the case?

 

[overscan (PaulMM)]

I don't think so - I think its more due to reusing components of existing aircraft.


Anyway, here's a nice photo I acquired on Ebay of the EFA mockup at Farnborough 1986.

Great stuff!

What happens to all the full-size mockups that get built for displays, like that red one at Farnborough?

Marginally improved drawing plus photo of Aeritalia AIT 320

Aeritalia AIT-320 was the study (never crowned by producing prototypes) of a modern air superiority lightweight fighter, developed since 1976. Thought of as the heir of Lockheed F-104 Starfighter , was equipped with a single turbojet RB.199 , the same who had equipped the fighter Tornado , which, however, is twin. Conceptually similar to the F-16 , recalled a small single engine F-18. Even France (with the ACT-88 - Avion de Combat Tactic), Great Britain (with its BAe P.96, P.106 and P.110 LCA) and Germany (with the MBB TKF-90) had developed models conceptually similar airplane single-engine light attack and combat daytime, prototypes or studies developed for this purpose, including just studying AIT-320/15, went to join in the various multi-national projects that would eventually lead to EF-2000 .

Sometimes kept - RAF Museum Hendon had one on display, now replaced with a real plane.

The P.96 was on a wall-chart at Paris in 1979.

The main counter-argument was "if we can't do better than the F-18 we might as well give up."

And if you were there at the time you'll remember that the basic F/A-18A/B was being touted as a wonder-jet that had all of the F-16's spectacular performance, but also had BVR capability built in (and in those days nobody realized yet how good the AIM-9L was) and would do precision strike with a targeting pod, and could haul 2 x 2k bombs over 500+ nm. Moreover, Northrop was offering the F-18L that would be even better...

Of course, a few years later in Opeval we found that the Hornet wasn't that good at everything, the Israelis showed how good the F-16 was, and it really took the F/A-18C/D to deliver some of the weapons and sensor capes that had been advertised. By that time, the Euros had set requirements to beat the Hornet flip-charts (this was before anyone had PowerPoints. Fancy that!) and we were on the road to Rafale, Typhoon and Gripen.

Interesting to see the Northropesque Diamond wing design.

Didn't Dornier work closely with Northrop for a while...or was that someone else?

 

[overscan (PaulMM)]

Yes they did, with the collaborative ND-102 design.

Yep, that was the one I was thinking of.

BAe project meant to replace the German F-4 and British Jaguar, around 1979-1980.
Pictures from Le Moniteur no.33 show a mock-up with two fins and a model with single fin displayed at Hanover 1980.
Study was done in parallel to the MBB TKF-90:

[Avimimus]

A nice looking mock-up. It looks like the design is a lot bigger than the Jaguar though.

 

[Antonio]

The ECA model in picture 2 can be found in British secret fighter projects pg 133.

The mock up in the first picture could be a BAe P.110 instead?.

You are right, I did not think of looking there before posting.
I think the mock-up is that mentioned on p.134 under the ECF heading (European Collaborative Fighter). The magazine was published in June 1980, this seems too early for the P.110.

 

[overscan (PaulMM)]

I've never been certain what that mockup represents. Its not the P110. It may be the ECF mockup.

AIT-320

In the first half of the '70s, Aeritalia (born November 12, 1969 by the merger of Fiat Aviation, Aerfer and Salmoiraghi) continued to evaluate various preliminary plans to replace the G 91R. The AIT 311 had a configuration quite similar to the AMX future, but powered by two General Electric J85, the same as the G 91Y. The compact AIT 315, powered by a General Electric TF34 turbofan, had two guns in the dorsal position. The most ambitious AIT 320, supersonic wing media would have to mount a Pratt & Whitney F404 or a Turbo-Union RB.199. (Archive Aeromedia) In the first half of the 1970s, Aeritalia (formed on November 12, 1969 by the merger of Fiat Aviation, Aerfer and Salmoiraghi) continued to evaluate a number of preliminary projects for an aircraft intended as a replacement for the IAF G 91R. AIT had an AMX-311 like general configuration, powered by two General Electric J85, the same engine unit as the G 91Y. The compact AIT 315, powered by one General Electric TF34 turbofan, was fitted with a pair of cannons in the dorsal position. The more ambitious AIT 320, a mid-winged supersonic aircraft, was powered by either Pratt & Whitney F404 or Turbo-Union RB.199. (Archive Aeromedia)
