    The senate doc do not mention CPFH. Easy to find anyway. So in the end, better use Rafale C and deduct 20% VAT.

    Longer ranges sensors? How do you know that? And in what the Gripen solution would be less “comprehensive” than F-35. There may also be a huge gap in CFPH.

    Other than the CMC material, just like the M53 and other engines by manufacturers the world over going right back to the 1950s, in other words.

    It works reasonably well, and may have a minor IR signature advantage, but in terms of (supersonic) performance, con-di wins – handsomely.

    The CMC mateerial stays cold, thats why it emulates con-di. like (something very different), the air intakes used compressed air to emulate a shock cone (another “simple” way)

    Agreee. i just mention the numbers given to me by SAAB. Btw, Swaf chief of staff said after ACEX that Gripen C with MS20 software (enhancing radar performance) with METEOR is maybe the best plane in the world atm.

    Weapon bays will be opened just in case of poor weather demo. Not very probale according to meteo here;.. (35°C)

    no. M88 sfc is lower, sorry. the convergent/divergent effect is obtained using cold CMC outlets. expansion of hot exhaust from hot flaps is further guided by cold parts. emulates con di nozzle, zimpler and far better for IR signature.

    IF you want numbers with the exact kg, they nusually vary between two airframes you know?

    They told me for E, roughly empty weiht 8000, MTOW around 16500

    Between M88-3 and EJ200 they are similar, but M88-2, as relevant to EF engine selection was a long way inferior.

    explain? tW ratio, lifetime, SFC are very simiilar.

    They did not want to disclose yet during first flight web conference.

    74 M€2013 pour le Rafale B (pour 110 avions) de 68,8 M€2013 pour le Rafale C (pour 118 avions) et de 79 M€2011 pour le Rafale M (pour 58 avions).

    including AESA radar and 20%VAT For M (carrier version) Of course you try to compare F35A to Rafale M, well no it should be compared to Rafale C. FY2018 F-35A cost 87 mil according to latest SAR? So no, less expensive. Not to talk about CPFH…

    Main difference to me from older demos i could see on youtube etc. Is the way pilot is precise in roll control (earlier demos, they always needed a correction at the end of the rool). Don’t know if it is due to pilot or FCS improvement.
    Apart from that nice demo, yes, albeit not as “sharp” as some i’ve seen. (which canbe explained by the small size of the box and the inertia of a large fighter).

    Snecma M88-3 is only around as a prototype just as EJ230/XG-40-2. At the time the choice was EJ200 or 17,000lbf M88-2 and even the M88-3 doesn’t beat any of the core parameters set by the EJ200, thrust to weight no better, SFC no lower. And yes, I can say the EJ200 was definitely better, and that’s what the other 3 EF partners also said. And you can’t seriously compare an engine that was flying 20+ years ago with the F135. The EJ200 was first ran in 1991. The JSF competition didn’t even start until 1996 and the X-35 wasn’t selected until 2001. You’re talking about a time gap of 15 years.

    Guess what? the FCAS -DP (the drone) engine is a M88 derivative made by RR/snecma joint venture. if you check characteristics, SFC, TW etc. are very similar between EJ200 and M88. Rest is operationnaly relevant (eg time from 0 to 100% thrust, air density response), but generally not advertized.
