    Re: Marussia sports cars

    Good evening everybody and an early Happy New Year to all of you!

     

    As promised, I am back to voice my disagreement to some things that have been written.

    Dear "dremacar", I never questioned anyone's honesty, just some of the arguments that have been put forward as facts. I fully agree with you on the facts regarding the Concorde. Some of your assessments do the Tu-144 injustice though.

    It is a well known fact that the early versions of the Tu-144 was fitted with turbofan, rather than turbojet engines, as the latter were still in development. Anyone who knows a thing or two about planes knows that turbofans, though great in general, are much less efficient (i.e. in fuel consumption) than turbojets at supersonic speeds. Thus, the Tu-144 indeed needed to make use of its afterburners as it could not supercruise on military thrust alone with its four (4) Kuznetsov turbofans. This was remedied latter with the introduction of the Tu-144D that featured four (4) Kolesov turbojets (rated at 200 KN of thrust each, thus being considerably more powerful than the Concorde's RR engines), while achiving comparable range via the supercruise capability.

    Easyrider, the retirement of the Concorde was indeed a great loss, as was the retirement of the Tu-144. Although the Concorde was initially the more accomplished aircraft, it was by no means superior to the Tu-144D that remedied the innefficiencies of the earlier, rushed versions. The finished article, namely the D version of the Tupolev, was larger, quicker and had the same range as the Concorde.

    I fully realise that you are not questioning anyone's honesty. I merely wished to substantiate the claims that you appeared to have considered inaccurate.

    Both are superb aircraft, a pity, a thousand pities, that neither are ever likely to grace the sky again, even though a small group are endeavouring to run up and taxi F-BTSD stored at Le Bourget, Paris, an aircraft that held the world record for the fastest round the world passenger flights, both east and west bound. I consider myself very privileged to have flown in Concorde in her final few months of service, an experience I will never forget. But I think we will have to agree to disagree over our opinions as to the superiority of Concorde.

    I wish you and yours a very Happy New Year also. Smiley

    Re: Marussia sports cars

    At least we agree that both aircrafts were superb technical achievements and that it's a great pitty they don't adorn our skies anymore. 

    My best wishes for a positive and meaningful 2011.
