  1. Re:What's the market? on NASA Wants To Get Supersonic With New Passenger Jet (networkworld.com) · · Score: 1

    Probably just for pilot training - using Tu-160 for anything other than that and scaring Americans is far too expensive.

  2. Re:What's the market? on NASA Wants To Get Supersonic With New Passenger Jet (networkworld.com) · · Score: 1

    Turbojet is only less efficient than a turbofan when flying at low speeds. At Mach 2 there is not much difference because high bypass turbofans cannot achieve this kind of speed - in fact, the higher the bypass is, the lower is the maximum speed - and low bypass turbofans are basically leaky turbojets which use the bypass air stream more for cooling than for propulsion.

    Yes, the latest Tu-144 used by NASA had turbofans borrowed from the Tu-160 bomber, and they were much more efficient than the Olympus turbojets of the Concorde, but they were more efficient not because they were turbofans (the bypass ratio is quite modest 1.4:1) but because they had almost twice the pressure ratio due to a 20 years more modern and complex design (three spools, one more compressor stage, twice the number of turbines, a 300ÂC higher turbine inlet temperature and so on).

    Blah blah blah. Even China and Russia build high speed rail - China is about as large as USA and Russia is twice the size. High speed rail would work just fine for routes like New York to Boston or, say, LA to Las Vegas. Or Miami to New Orleans.

    Plants don't need just warmth, they also need sunlight for photosynthesis. There is less of it in northern latitudes. Also due to the warmth there will be more water vapour in the air, thus more clouds - even less sunlight.

    Not just hatching early, also breeding in the wrong season. We had blackbirds breeding in december due to another autumn heat record, the offspring hatched in january and died quickly because there was no suitable food around - only berries, no insects.

    Well, the thing is that there have been two revolutions in Russia in 1917. The first one (the february revolution) forced the tsar to abdicate and established a republic with a provisional government (a coalition of democratic socialists and classic liberals). The second one (the october revolution) was a bolshevik coup which overthrew the provisional government, and was, strictly speaking, unnecessary.

    Here in the western part of Germany we had no winter for at least three consecutive years. We had just a late autumn going over to a very early spring. In fact, we had such a warm december (up to +15C) that blackbirds started to breed and the offspring was quickly killed by the lack of suitable food in january.

    I have several pairs of cross country skis in the cellar that haven't seen snow for years even though I live in the mountains. I didn't even have to change my bicycle tyres to studded tyres this winter and last two winters I had to change tyres only for two days or so.

    You have your history confused even more, which is not surprising, due to your your political views and general stupidity. The shah was installed by the Brits in first place by invading Iran and forcing the previous shah to abdicate. Oh by the way, that previous shah was also installed by the Brits 20 years before.
    And Mosaddegh was democratically elected.

    Not necessarily. Road bike brakes aren't that strong and the very narrow tyres haven't a lot of stopping power. Cyclocross bikes have somewhat wider tyres, but they often use cantilever brakes which suck donkey balls when it comes to stopping power even compared to v-brakes - basically the lowest brake version for cheap city bikes. Better ones use hydraulic disc brakes - which are allowed on cyclocross nowadays but not many riders use them yet.
