    PESA CAN’T PULSCOMPRESSION THERFORE IS PESA A LOUD CRYING RADAR SYSTEM!

    Why ? Now we all know what you’re talking about, why can’t a PESA use pulse compression ? 😎
    Yes of course, a PESA is not an AESA, but then ?

    6 surfaces? Which 2 else except the ones at the wing trailing edges?

    Canards = 2
    +Trailing edges = 2×2
    —————————-
    6

    And no it can not. Its not possible to brake while manoeuvering as the control surfaces are needed to realize the pilots control inputs. The FCS will break brakeing as long as the control surfaces are needed to pitch or roll the aircraft. When the pilot finished his control inputs control surfaces will move back to the brake configuration as long as it is activated. That could be a disadvantage in some situations.

    Why do you write that ? Did someone told you about that ?
    Because of this requirement, I believe that the engineers have expected the problem. I think that even when the Rafale is turning hard, its control surfaces aren’t in their max position. This would let them do an additional movement, so as to have the airbrake applied whatever the control surface are doing.
    In your paragraph, you suggest that the Rafale can brake only when flying in a straight line, wich is very strange, for any aircraft. But I think that you’re wrong, i think that the control surfaces can move widely enough to maneuver the aircraft and brake at the same time.

    Can’t say anything about the Rafale.

    There have been several propositions here. In 1996, it was said that a M88-3 of 90kN could be built, and also a M88-4 of 115kN. But with no foreign customers, and lack of credit, all of this has turned to the M88 ECO (90kN and longer life etc). Maybe one day, studies on the M88-4 will be funded… ? 😮

    I believe that the 9.5 tonne weight was a target weight for a specific version that dates from the various lower cost Eurofighter Lite proposals made when the Germans were about to bale, along with the single-engined, canardless and other low cost proposals.

    I think too.

    An A-G capability was always integral, and there was no weight increase. Sorry.

    Well, that’s because the Typhoon story is often reported in a wrong way. Actually, the requirements of the 4 countries weren’t exactely the sames.
    It is true that British wanted to replace Jaguar etc.
    But in the same time, the German and Italian wanted mainly a superiority fighter.

    The story of the weight increase isn’t clear. 9,5 tons was the weight of the EF as the German wanted it to be (at the very begining). But British have planned it to be 11tons for a long time ago.

    Phil, in your signature, replace “Je suis venu. Moi scie et moi ne croyons pas mes yeux !” by

    The actual radar cross section is of course classified, it is however
    set out for the RAF in SR(A)-425. According to the RAF the Eurofighter’s
    RCS more than exceeds these requirements. More recent comments from BAE
    seem to indicate the radar return is around four times less than the
    Tornado. During a recent press event BAE Systems stated that the
    Typhoon’s RCS is bettered only by the F-22 in the frontal hemisphere and
    betters the F-22 at some angles. Although the later comment is very
    questionable it still indicates a real attempt to reduce the Typhoon’s
    radar signature. This should enable a Eurofighter pilot to remain
    undetected by his enemy until he his significantly closer than he may
    otherwise be able to achieve.

    Then, you don’t make the difference between truth and advertising.

    In addition, four times less than a Tornado isn’t impressive, and you missed the moment when a commercial said “10% that of the F-15”, wich isn’t impressive as well.

    Typhoon’s RCS is bettered only by the F-22 in the frontal hemisphere and

    LOL 😉

    The general impression in this thread is that the Rafale has a lower RCS than the Typhoon. According to SOC at least, can you explain why you have come to that conclusion?

    Some people think that because of the way it looks in photographs. These people see in radio wavelengths and thus are able to tell just by looking.

    How many CFK on a Rafale?
    Only the tail fin an some minor things, this is not really good for an
    low RCS. Which plane has intake and first compressor stage in straight
    line –> Rafale and this is not good for a low RCS.
    S-curved intakeduct –> F-22, EF, F-35, this reduce the RCS.

    I don’t understand what is the problem with that…
    I think the three guys I quoted don’t read about the Rafale.

    If they had read, they should have seen that discretion was an early requirement.
    They should have seen that on the airframe, there are little to no right angles, no discontinuity, very smooth shapes, etc. On pictures, they should have seen that the air inducts are double-S shaped… This is not just to make the aircraft look sexy.
    Some parts are more difficult to hide, also, they are covered by RAM, control surfaces and all doors have shark tooth, there is a very thick gold layer in the cockpit glass (so as to prevent EM waves from entering the pit), and the fin is made in a EM-wave transparent materials. The nose will only allow for the RBE-2’s wavelenghts.
    The engines are also designed so as to have little to no effect on the aircraft IR-signature, and use some RCS reduction technologies.
    Dassault & Coe have made every efforts to lower the RCS / IR signature of the Rafale, and they will go on, by designing new stuff, such as stealth pods for weapons, for example.

    All of this do not come from my imagination, it only comes from my readings since 16 years, in French papers essentially.

    Please don’t get confused between blacking out under “g” and “g-LOC”. They are two different conditions.

    Thanks, but I know. I was just adding something about my previous post.

    But I know nothing about what the thread started about… Sorry 😮

    Yes. These must be very soft discharges, but it has been reported in a study about what was new with the Rafale in the AdA. Before (->M2000), Gs were “painful” enough, but with the inclined seat, the Rafale pilot feels like under approximately 2g under the actual value (pain and black out delayed by 2g). And so, (soft?) electrical discharges are sent in the pilot elbow the tell him when he is pulling over 6g.

    Actually, I’ve never heard about such systems, but sometimes, you can find some trick to prevent it :
    In the Rafale, turning is so much comfortable that the aircraft gives an electrical discharge in the pilot’s elbow, when pulling more than 6g. This is a way to remember him what he is doing, and to tell him “be careful !”…

    But I don’t know if the aircraft can monitor the pilot so as to check whether he is conscious or not.

    The Mirage 4000 canards were adjustable (also in flight), don’t know the angles of deflection, but not moveable in the real sense.

    That’s it. The pilot could move the foreplanes as required by the situation. They weren’t piloted by the FCS. 🙂

    “Gentle turning fellow and Fedupkin man you may hav trolling technic but you have NO knolidge of aerospacial, only a limited comprehension of what you are bubling about and a taste for escapism manure of the sort pedalled by Typhoon fan club superioricist gurus.

    It works for both exports and crashes. 😀
