  1. Re:Why should Apple open up? on Apple Bans iPhone App For Competing With Mail.app · · Score: 1

    Since you sound like a Mac person, let me ask you this: What if Apple came out with their own massively powerful graphics editor, and then they told Adobe to take a hike because Photoshop was competing with their app on OS X. No one would stand for that. Yet everyone seems to accept it on the iPhone. It's unacceptable.

    The only, and very valid reason, that is acceptable on the iPhone is because it is a completely undeveloped market, unlike OSX or Windows which are both very developed markets.

    Ok, stop taking the drugs, they don't seem to be doing you any good. Seriously, get some fucking perspective please - there are degrees involved here, just as there are in speeding.

    If I speed, I get a ticket and some points on my license. If I speed a lot and accumulate points, my license gets taken away from me and I get to take my test after my ban expires. If I speed in such a manner that my driving causes immediate risk to other persons, then it becomes a whole different ball game - if theres simply speed involved (eg I'm going 30mph over the limit rather than 5mph over the limit) then I get larger fines and an immediate ban. If there are other considerations, such as bad weather et al then I get charged with a whole other offence - dangerous driving. All of the above are things that I have to declare to my employers or prospective employers, especially if I drive on business.

    If this person was simply giving copies away to friends, he wouldn't be facing these sorts of penalties. But he isn't. He took the risk. Him. I'm not going to cry for him.

    Boo fucking hoo - Activision are well within their rights to take this person to the cleaners. There isn't any way I'm going to tow the Slashdot party line here, because its ludicrous.

    Why should a friggin' IT pro be doing COST ANALYSIS? Isn't that a management function? The IT pro is supposed to do IT. They're not business experts. Not only are they not qualified to slap together some well meaning but totally invalid cost/benefit analysis, but it's not even their job. That's the job of management. They're the ones with business degrees. They're supposed to know how to do that. Their job is to take information from the IT pro and compile it to get the cost/benefit.

    I'm so sick of IT folks acting like they DO understand business and putting together risk analyses that are all gloom and doom.

    Experience - I used to work for Rolls Royce plc (the aero engine divison of Rolls Royce).

    Turbofans are shrouded for a reason, if it was more efficient to unshroud them, they would be unshrouded because that shroud represents a hell of a lot of weight that an airline would most certainly not want to carry around.

    The shroud plays two major parts - containment in the event of blade failure, where the fan loses a blade, and smoothing of the airflow through the engine. Having a smooth airflow through the engine reduces resistence significantly, and allows for better performance of the turbine itself, as well as cleaner air flow out of hte back of the engine. This can add as much as 5% benefit in terms of engine efficiency.

    I would think that blade containment would be self explainatory, but incase it is not:

    A Trent 900 turbofan (the powerplant for the A380, alongside the GP7200 from GE and P&W) rotates at between 2,900 rpm and 3,000 rpm. Your PW124, which powers regional aircraft such as the Fokker 50, has a maximum rpm of between 1,300 and 1,600rpm.

    A Trent 900 has 24 116" fan blades, each weighing about 4 times that of the 5 blades the PW124 uses. Thats one fuckton load of potential energy you have there, when the engine is at full power - the tips of the blades are actually supersonic.

    In the event of one of those blades leaving the hub, the shroud is designed to contain the entire blade and any ejecta caused by the separation event within the engine - the engine destroys itself but causes little or no damage to the rest of the aircraft. On a regional aircraft, the blades are light enough, small enough and slow enough that you can protect the body of the aircraft.

    In any case, I think the very fact that there are many many turboprops in service today with regional airlines proves that 'passengers think turboprops look scary so airlines don't use them' is completely wrong, without having to go into all what I did.

    It most certainly is not about looks. Airlines would use whatever they deem lowest cost.

  9. Re:Turbopropellers on Plane Simple Truth · · Score: 1

    The problem with turboprops is that they are most efficient at lower altitudes, which means more wind resistence on the fuselage. This basically limits them to short to short-medium sectors before they start becoming less efficient than larger turbofan aircraft.

  10. Re:Report is wrong... on Plane Simple Truth · · Score: 4, Informative

    I pretty much disagree with everything you said - theres very good reasons why RR, GE and P&W (plus all the lesser bit players in the civil engine market) produce primarily turbofans for the large civil aircraft market.

    Firstly, turboprops still have the vibration issue that plagued piston engined aircraft. Sure, its drastically reduced, but it still raises the cabin noise level significantly over a turbofan - which means you need more sound reduction material to counteract it and bring cabin noise levels down, which means weight.

    Secondly, turboprops are high power but only in certain bands - and increasing the size of the props to give a better power band is not easy, as it increases the strain on the gear box among other things. You seem to be under the impression that

    Thirdly, because of the size of the props we are talking about, they need to be mounted on a high wing rather than a low wing. This means significantly added cost and more importantly weight, as you need to transfer the wing load down through the body of the aircraft to the undercarriage. Or you use wing mounted main gear, which has to be significantly larger than on low wing aircraft because you are now transfering the load a farther distance. Thats all extra weight to carry around.

    Fourthly, turboprops aren't as powerful as you think - the A400M needs 4 TP400-D6 turboprops to lift a MTOW of 141 tonnes, or 311,000 lbs. An A330-200 has a MTOW of 230 tonnes, or 507,000 lbs with only two Trent 700s. And even then, the A400M only has a 3,800nm max (dependant on configuration), while the A330-200 will be topping out at 6,800nm.

    In short, theres a damn good reason why the airline industry uses turbofans, and its not because they are shiney.

  11. Report is wrong... on Plane Simple Truth · · Score: 4, Informative

    For a start, they seem to hinge their conclusions on per-seat-kilometer values, and then seem surprised at the outcome - per-seat-kilometer values miss significant aspects of the subject at hand:

    1. Cargo - planes carry significant amounts of cargo today, on the piston engined aircraft of yesteryear it was pretty much 'passengers OR cargo, but not at the same time'. Thus the plane today is doing work that your plane of yesterday would be excluded from because you aren't getting a per-seat-kilometer value for it (no seats).

    2. Range - planes today carry out some serious routes, with the top end of the scale actually topping out at between 8,000miles on a regular basis (there are longer routes, but they are less common). You won't be getting that in piston engined aircraft.

    3. Reliability - jet engines are much more reliable than the piston engines of yesteryear, which is why we now have ETOPS (extended-range twin-engine operational performance standard) hitting 207 minutes. Thats three hours and twenty seven minutes distance from an airfield on one single engine. Try that in a piston engine aircraft of yesteryear.

    4. Reliability - yes, its worth mentioning again. Jet engine aircraft can run sectors with minimal turn around, with minimal maintenance between sectors and with minimal top-ups of required fluids. Piston engined aircraft required a lot more in the way of coaxing and looking after on the ground between sectors. More time in maintenance means less time making money.

    5. Longevity - there haven't been many piston engine aircraft that were built for two or three decades in passenger service (the DC-3 comes to mind, but not many others). Most piston engine passenger aircraft of the pre-war and immediate post-war period were designed to last only a few thousand hours, or a couple of years in passenger service.

    Oh, and yes, I'm related to the aviation industry :)

    3. Basic mining and refining of ore with support from Earth - the initial tools to do the job are brought up from Earth
    4. Self sustaining basic mining - refined ore is used to produce replacement parts and new tools
