    😀 Non-Sens.

    You mistook that Avon variant with a later ones used in the Draken

    Bernard Waquet, propose de tester l’installation du réacteur Avon 67 RB 146 sur la cellule d’un Mirage IIIB modifié pour servir à la fois d’appareil d’entraînement et d’appareil d’attaque.

    http://www.geocities.com/tanioskahi/aus1.html

    The first Mirage IIIA flew in May, 1958, and eventually was clocked at Mach 2.2, making it the first European aircraft to exceed Mach 2 in level flight. The tenth IIIA was rolled out in December, 1959. One was fitted with a Rolls-Royce Avon 67 engine with thrust of 71.1 kN (16,000 lbf) as a test model for Australian evaluation with the name “Mirage IIIO”. This variant flew in February, 1961, but the Avon powerplant was not adopted.

    Oh, and the better one :
    http://www.defence.gov.au/raaf/raafmuseum/research/aircraft/series3/A3.htm

    A French Mirage IIIA, known as ‘City of Hobart’, was fitted with an RB146 Avon 67 turbojet and flew on 13 February 1961. This was known as a Mirage IIIO, but did not receive a RAAF serial number as, although this modification delivered superior performance, its cost was prohibitive and this project was discontinued.

    So, the Mirage Avon actually flown the Avon 67 RB146. Dot.

    Even the similar Draken was not able to supercruise with that later Avon!

    Nothing, really nothing similar. Air intake in the first place.

    By the way, the later Lightning Mk.6 was equipped with RB 146 Avon, which did deliver 49 kN to 72 kN.
    Please do not claim such nonsense.

    I’m so sorry. 😉

    To reach supersonic in level flight at those days, you were in need of AB-thrust always.
    When dry thrust drops related with airpressure, the AB thrust does not in a similar way for physical reasons!

    :rolleyes:
    I perfectly understand what you mean. I’m not good enough in this field to answer you, but I think you’re trying too hard to deny a fact…
    Dassault reached Mach1.3 with the Avon 67 RB146 engine on a mere Mirage III (a fighter especially designed for poor engines, as all french jet fighter).

    The dry of the Atar 9K-50 was 49.2 kN, when that of the Avon 67 was 44.5 kN only. The Avon did offer a better climb-rate at first compared to the Atar 9B with 42.0 kN dry.

    The Avon 67 RB.146 could produce :
    -5620 kg of thrust (which convert into 55kN) in DRY;
    -7260 kg in PC (=71kN)

    Also, 55kN is much more than the 42kN of the Atar. Also, since the Atar 9B max PC thrust was only 59kN…
    In fact, even with the Atar 101G and no “mice” in the air inlets, the Mirage III could reach Mach1.52 (only 44kN) (prototype 001 “Balzac”).
    Later, the Mirage IIIA (with the “mice” added in the air inlet) could reach Mach2.0 only with its new Atar 9B (59kN), and Mach2.2 with rockets.

    It’s quite clear to me that this one could really supercruise at Mach1.3 with the Avon 67 RB.146 engine (55kN dry; 71kN PC).

    I don’t know how the pilot is warned (sound ? voice ? ligths ?) but i know that in such a situation, the pilot just has to confirm the activation of the Terrain Following Autopilot.
    For the F3 standard, the autopilot will be able to engage automatically in TF mode in case of emergency.

    Sorry Tmor,
    You misundertood my post.

    Ok, sorry too, no problem.

    Gift or payed is not a good toy to give to someone as Kadhafi

    This has raised a lot of controversy in our home land. But we’re a bit off-topic here.

    Exactly,
    I have some doubts, considering that the pilot was one of the best of AdA. 10 years flying, 1700 hours flying, mission in Afghanistan and the highest qualification of the AdA pilots ‘Chef de patrouille’ that means a Top Gun of french air force.
    It’s worth nothing that ‘Flight data recorder’ is missing.

    http://www.20minutes.fr/article/199514/France-Pour-la-premiere-fois-de-son-histoire-un-Rafale-s-est-ecrase.php

    Could I have doubts?

    Spatial disorientation and G-Loc have nothing to do with pilot experience, unfortunately…
    http://www.lemonde.fr/web/depeches/0,14-0,39-33556565@7-50,0.html
    As you can see, the flight data recorder was discovered 100 meters away. Since that moment, according to the extracted data, the pilot was trying to maneuver vertically instead of horizontaly when the crash occured : spatial disorientation (due to G-Loc ?).
    This is not truly a human “error”, but it’s due to the pilot.:(

    This article does not come from a french mass media.

    The nuclear reactor will be bought, no gift.

    According to your ironic tone in your post, you seems not te believe the human error theory.

    Get lost, little boy. You should have kept your humour for yourself.

    Again, the US navy pilot maybe over enthousiastic, but still he was not obliged to say so if he didn’t beleve a word of what he is saying. It is a good indicator that rafale RCS is good; (I am not saying it the best)

    I’ve no problem with his testimony. It’s really perfect. But my point was that you have to understand that this guy hasn’t flown a F-22 for example… (actually, we don’t know). According to your last words, you agree on this point.

    but don’t think everybody is lying to you.

    Calm down. Re-read your article.

    The Dassault Aviation Rafale has had almost a charmed life in the world of fighter aircraft. In the almost quarter century since the aircraft first began its development and then entered into service with the French Armée de l’Air (AdA) no aircraft had been lost until this week.
    Lovely sentence for the begining.

    The Rafale aircraft had taken off on Thursday from the AdA airbase at Saint-Dizier and later crashed in the township of Neuvic, Corrèze, in an uninhabited area. According to the AdA, two aircraft had taken off on a training mission that called for a nighttime head-on intercept at an altitude of 4000 metres. “One of the aircraft successfully completed the training intercept and then went into a dive and plowed straight into the ground,” said a source familiar with the AdA’s investigation. “The speed at which he impacted was so high that there were pieces everywhere on the ground.” The pilot, who was an experienced aviator, did not survive the crash. It is unknown at this time how a pilot could have become disoriented at night at such a high altitude and not have been able to recover before crashing.

    The Rafale fighter has long been regarded as one of the most advanced aircraft of its kind.
    Its flight control system (FCS) is the envy of most other designers and permits the most carefree handling possible. One US pilot who flew the aircraft at Le Bourget pointed out the revolutionary automation that the FCS facilitates. “Coming in for a landing approach there is no need for adjustment of the flap controls–and no controls to adjust them with if you wanted to,” he said. The flaps, canards, and power management controls of the engine are all linked in one of the most sophisticated FCS architectures ever devised.
    So, according to the fact that flap controls are automated, those FCS are “the envy of most other designers” ? Didn’t the journalist find other testimony ? He just picked the newest available.

    Dassault had long been famous for its several generations of “Mirage” aircraft, from the Mirage IIIC that had been the workhorse of the Israel Air Force during the 1967 Six-Day War to the latest model, the Mirage 2000-5 MkII that recently ended production. Dassault has manufactured 601 of the Mirage 2000 models, the last of which was delivered to the Hellenic Air Force at a ceremony in Tanagra Air Base in Greece on 23 November.

    The Rafale was designed to be the next-generation successor to the Mirage 2000 series, and incorporated a number of new, leading-edge technologies that in some cases were the first of their kind to be on-board a NATO aircraft. It is currently the only military aircraft built by Dassault, but the programme is still profitable and on schedule, which is rare for most military aircraft that call for the introduction of so many new-age systems.(thanks for reminding us) Its Thales RBE2 radar is regarded as one of the most advanced in its class (and what about criticizism ?) and had a unique feature in that its passive array (PESA) antenna can be removed and replaced with an active electronically scanning array (AESA) in one of the easiest and effective upgrades of its kind.

    Another impressive aspect of the Rafale is that it was designed from the ground up to be both a land-based and carrier-based aeroplane. Not until more than a decade later when the U.S. armed forces decided to procure the F-35 Joint Strike Fighter (JSF) would another combat aircraft be developed with both naval and conventional take-off applications as part of the requirement.

    As impressive as the aircraft is it has had little success in the export market, sales that the program needs in the long run to keep the production line open. Near-misses in competitions in South Korea and Singapore saw the Rafale muscled out by the US lobby and government-to-government influence that convinced both nations to purchase the Boeing F-15 instead. (this journalist clearly sides with us French) The Dassault jet also was in line for sale to Saudi Arabia and Morocco, but in both cases the official French arms export agency, the Délégation Générale pour l’Armement (DGA) is regarded as having fumbled the ball at critical moments. (bouc émissaire)

    Next week, Libyan leader Muammar Gaddafi will visit Paris–the first such visit from a Libyan head of state to take place in 30 years–and is expected to sign a deal to purchase 10 to 14 Rafales for the Libyan armed forces. Dassault is also involved in a program to upgrade and refurbish the older Mirage F1s that Libya previously had in inventory.

    As with every other fighter manufacturer in the world, Dassault is working hard to win the tender for 126 fighter aircraft–plus options for 63 additional fighters–from the Indian Air Force (IAF). Dassault is in a better position than most of its competitors (nice, but…), as the IAF already operate the Mirage 2000 and the continuity and commonality between it and the Rafale offers some synergisms that only the Russian competitor, RSK-MiG can also claim.

    Currently there are three investigations looking into the crash, but there appears to be no clues as to why the pilot decided to make the maneuver down to the hard deck and no indications of aircraft malfunction. Given that he did not survive, the fault is likely to be assessed–as it often is in these situations—as “pilot error.” The crash is not expected to mar the image of the French-made fighter, which has had a stellar record to date and–unlike other European aircraft programs–has almost all of the weapons designed for it already integrated and operational on the airframe.

    This past year both AdA and Marine Nationale (French Navy) carrier-based Rafales participated in combat sorties in Afghanistan. The Rafale also made history in a missile firing exercise when one aircraft locked onto a target drone and then electronically handed off the target data to a second Rafale, which fired and destroyed the target.(it was just the first time it happened).

    The aircraft’s advantage, in the words of Dassault representatives, is that the aircraft is many times underestimated.
    I agree 😀

    “Most people–when they see the Rafale for the first time–they make fun of the aircraft or do not think much of it,” said one Dassault program official. “But after they have had a chance to see what it does and how it performs their opinion changes quickly. (:rolleyes: ) What all of us see is that there is a significant gap between Rafale and the aircraft it has replaced, so it opens up a number of capabilities and possibilities in any joint operations.”

    In fact, this article is just like an advocacy by Dassault PR… I may be interesting for beginers.

    Sorry if I have to say that but that sounds very much like Dassault propaganda

    Dassault’s propaganda wouldn’t be different, i agree. Then it would be interesting to see if Dassault paid the journalist ! 😀

    Especially not when nothing really new is said, just a little bit old stuff being cooked up, mixed with some hype = “super” article

    I fully agree on this.
    This article has nothing new to bring.

    When it comes from dassault’s mouth its called propaganda,

    Normal.

    when it come from an AdA pilots it is called propaganda,

    Aguable.

    and even when it comes from a foreign independent paper with a foreign pilot (US) it is called propaganda!!

    Of course not, but yet, we have to know the pilot’s background.

    Meteo was really poor, no visibility.
    The aircraft felt nearly vertically, from 4000meters high, and reached the ground at nearly 900km/h.
    Debris weren’t scattered on several kilometers at all. In fact, it only left a hole, and the body has finally been discovered buried at 10 to 15meters deep.

    Because there has been no communication, no ejection, the G-Loc is more and more a good explanation. Unfortunately, flight recorders seem to be lost…

    RIP, “Bouba”. 🙁 Condolences to his family.

    Why sawtooth by the Rafale, no swept gaps on the flaperons! I see a lower wing and canard swep, that all not really good for a low RCS!:diablo:

    Oh no !!! Go teach Dassault men how to make their fighters more stealthy !!! 😉

    Actually, the M has no visible RAM treatments as shown in the other picture with “sawtooth” treatments on the trailing edges of the wings and canard.

    :confused:

    Because its radar signature requirements are not as stringent as for the AdA – indeed, this only reinforces SOC’s argument.

    And so, I’m a clown ? 🙂
