Dassault Mirage G8A / ACF / Super Mirage

Hello,
Thank you :)
If I knew that my drawing would have been published on a 2 pages, I would have made much more effort in my rendering!! Too late...
I give you here the file in high quality that I delivered to Le Fana. Basically, I took a previous plan from a few years back and tried to add more details with inspirations from the Mirage 4000. Le Fana wanted to have this Super Mirage with some missiles in test and high visual colors, so I figured out to represent the M550 Magic and M530, which were from the same time period.
Enjoy,
Regards
Alain

Thanks Alanqua

I saw quickly the Fana 580 in the supermarket. The article seems to be very interesting. I wait for my monthly copy in the letter box, but it doesn't come yet... :'(
 
The Super 530F entered service with the F1C-200s around 1981 (from memory) so the ACF would have it from the start.

Considering the enormous expense that was the ACF, there was no way it would have carried the very bad, outdated and innefficient R-530 (IMHO of course)

Or perhaps in an emergency only, firing them Vietnam style, in salvoes, with the hope that one of them would kill a Mig... randomly.

(a F-1 pilot once told about firing a test R-530: the freakkin' missile went crazy and turned a barrel around the Mirage, to the great... stress and dismay of the pilot. It finally shot down... a cloud, nearby)
 
Hello,
Originally for this work, Le Fana requested some missiles represented in color markings for aerial tests. After some research (wikipedia) I found out that:
- the R530 entered in service in 1963 and was produced until 1978,
- the ACF project was abandoned in 1975,
- the super 530F missile entered in service in 1980 and production ran until 1985,
So, I imagined that, if the ACF would have survived political turmoils, it could have potentially used R530 missiles for first basic trials (let say tests for mass, inertia, positionning, aerodynamics, etc...), before using the Super 530 F and D eventually. I thought that, using Super 530Fs would have portrayed an ACF in a "lately" period (around 1980) and at that time it would have been already in service. Isn'it?
At least, that was the logic I pursued in doing the drawing.
What is your opinion on that?
Regards
Alain
 
I see your reasoning, but the Super 530 was explicitly specified for the ACF in the requirement and test missiles would have been available from the start of flight testing. It's unlikely the radar would have supported the older R.530, and for aerodynamic testing you'd use a inert round of the Super 530 shape.

Its still a nice drawing though :)

Design of the Super 530 began in 1968, with the start of development in 1971. The first firing of a controlled mock-up missile took place in February 1973, following ramp tests in 1971 and flight trials of the AD26 homing head in 1972. In July 1973, drop trials were carried out, followed by aircraft carriage and aerodynamic trials in the first half of 1974.

Development and evaluation trials by the Centre d’Experience Aeriennes Militaires (CEAM) continued from 1974 through 1977 and included live firings. The first fully guided firing took place in 1975, when a missile fired from a Vautour flying at Mach 0.7 at a height of 11,000 meters (roughly 36,000 ft) successfully intercepted a target drone flying at Mach 1.6 at a height of 18,000 meters (approximately 59,000 ft). The first firing from a Mirage F1 took place in 1976; following the successful conclusion of the trials, a production contract was signed in late 1977.

And the wingtip points right at Marcel Dassault himself (the man with the glasses, in the middle)
 
Does anyone know what radar was intended for the ACF?

The other day I came across a document from 1977 in which it was claimed by the French (to the British MoD) that the Mirage 2000's radar was based on that of the ACF but with a smaller diameter dish. Presumably this meant the Thomson-CSF RDM?
The document goes on to mention that in the event of Anglo-French collaboration on a Mirage 2000 derivative that Britain could probably provide a superior radar, so that might lend more weight to it being the RDM?
Does anyone have any more information?
 
I don't think its the RDM. The RDM was a quick private venture development from Cyrano IV - the French Air Force funded RDI. They took a few RDM equipped Mirages mostly to help with export optics.

I confess my knowledge of French avionics is patchy, hence my questions.

Pulse doppler (and the according look down / shoot down capability) took a very long time and arduous development in France.
I think the ACF (1972-75) was to have it, then it was passed to the 2000 after 1975 but slowed down to such a point, what became the RDI was not available until 1985 at best.
And so they quickly derived RDM out of the old Cyrano family (Mirage III / Mirage F1) for early batches of Mirage 2000: the ones that entered service in Dijon in July 1984.

It also boiled down to the difference between Super 530 "D" and"F". The latter was mated to the Mirage F1 and its Cyrano IV, but the whole thing certainly wasn't pulse doppler nor look down / shoot down.

The Super 530D was the pulse doppler missile, but it needed the RDI and both were too late for early 2000s.

So in a few words: the original plan for the ACF was something like RDI + Super 530D.
I have no clue when it would have been available, but the cancellation and shift to the 2000 led to delays.

Dassault was pretty good at airframes but SNECMA and Thomson CSF sucked a little at radars and engines. Matra was an in-between for missiles.

According to COMAERO, pulse-doppler was started for Mirage F3 in 1966-67 but abandonned for half a decade or more; until it was revived for the ACF, then the Mirage 2000. Was to be RDI, not RDM - Radar De Merde...

Hi!
Source https://www.key.aero/article/dassault-mirage-g-swing-wing-fighter-nobody-wanted

「Dassault already had the feeling that variable geometry was a road to nowhere. On 5 June 1972, it had offered to modify the second G8 prototype, which was yet to fly. The idea was to replace the VG wing with a fixed one of 55° sweepback, creating the G8A. This project was not taken up, but on 22 August 1973 the government issued a specification for a new fighter to enter production in 1979, and on 5 December Dassault was contracted to produce a prototype. It was to be based on the G8 airframe but with a thinner wing set at 55° sweep, and renamed as the Super Mirage to avoid any confusion with the US Air Combat Fighter programme.But the rebranding still wasn’t enough to save it. Newly elected President Valéry Giscard d’Estaing decided in 1975 to reorientate the project towards a single-engined fighter, which was deemed easier to export. That, finally, was the end of the G8. A new line of thought would be explored, with a return to the delta wing, eventually materialising as the Mirage 2000 — and fulfilling d’Estaing’s hopes.」

Sounds like that pilot would have needed some time to get the pilot's seat cushion removed from his backside...

That's certainly what I'd try for. Licensed production, design modifications, design your own unit entirely.
