"ANDREW ROBERT BREEN" wrote in message ... [1] Though the Ilyshin-62 certainly suggests - by eye at least - that someone had taken a long, hard look at a Super VC10 before picking up their pencil. I have a suggestion about the Ilyshin-62, *stay away*. I flew on a CSA Il-62 out of Beirut in 1993. The seating, even in first class, was like being strapped into a lawn chair. The pitch of the seats was generous, but you could not reach the seat pocket without unbuckling your seat belt. The baggage handlers put my dog and her crate in the passenger cabin with us because they could not be sure of she would not freeze in the hold. The Czechs used to keep two fat guys on call to sit on either side of Western passengers. One requirement was they eat their lunch just before takeoff and outgass to relieve cabin pressure at regular intervals. Not my experience but one of a very thin friend. |

The British government prevented one of the last from being sold to the USA. This means the last Comet retired from service while the Boeing 707 line was still producing new aircraft since the last 707 rolled off the lines in 1991. Or was it 1997 |

I did and the Comet was introduction for longer being about 10 years ahead of the 707 - a pioneering ground breaking plane. History will show it far more important to aircraft advancement than the 707. |

"Keith Willshaw" wrote in message ... "Eunometic" wrote in message om... With a modified Fueselage it of course became a great maritime patrol aircraft known as the Nimrod. Nimrod is apparently superior than the Orion: at least as far as the airframe is concerned. Please xplain your reasons for arriving at this conclusion. While the Nimrod is a fine aircraft the P-3 has had rather more export success. Our master of logic enters the fray. The VC10 and Super VC10 was a superior plane to the 707, yet the 707 outsold it. The burried engines ( speys and now BMW/Rolls Royce BR715 ) provide a significantly reduced radar signature. (Here lies the disadvantage of burried eingines: installing high bypass ratio engines required re-engineering of the wing roots) I seriously doubt that any real advantage accrues from this. Nimrod has a LARGE radar signature. The engines which are close to the fueselage mean that opperation with engines shutdown does not create significant asymetric thrust problems. Indeed opperation on 2 engines is I believe normal on long loitering patrols. The latest Nimrods I believe have a range in excess of 6500nm and can launch cruise missiles. They can be armed with sidewinders and presumably AMRAAM style self homing missiles is a possibility. AMRAAM is highly unlikley He is gussing now. With the correct systems and sighting they might even provide the RAF with a mini B52. The big wings must provide good altitude performance. Thats just silly. Nimrod simly doesnt have the payload carrying capacity. The RAF used to have a mini B-52 , it was called the Vulcan You must read what was written. |

Since we have to keep reminding the British that the *Vikings*, not the British discovered New Foundland. And when they did it, there *was no* Atlantic Ocean. Did this ocean appear afterwards? Christ!...musta been one bitch of a rainstorm wot?. Or someone towed Newfoundland from Scotland to Canada. |

Hardly The Comet I entered passenger service in late 1952 and carried only 36 passengers, the remaining fleet was permanently grounded in early 1954 by which time 5 out of the 9 built had crashed The Comet 4 didnt enter service until April 1958 only a few months ahead of the 707-120 History will show it far more important to aircraft advancement than the 707. It has the distinction of being the first but the simple fact is that Boeing made a shed load of money selling over 1000 aircraft and went on to build almost 3/4 of the airliners in service in western markets by the early 90's DeHavilland sold a grand total of 46 Comet 4 aircraft Keith |

DH _did_ infact, come up with a rebuild program that would allow the airplane to have some useful life. The only Comet Customer who took them up on this was the Royal Canadian Air Force, which had purchased two Comets to support the First Air Division in Europe. These remained in service until the early 1960s. ISTR Comets in service with Freddie Laker into the 70's. Dan Air used them until Nov. 3, '80 (something over 110 passengers which must have been fun.) Those were Comet IVs, not Comet Is. Basically an entirely new airframe with a Comet-like shape. They were entirely redesigned structurally, and a bit larger. (71,760 kg MTOW rather than 47,620 kg) They used Rolls Avons (With about twice the push) rather than the centrifugal DH Ghosts. The Comet IV was actually a pretty good airplane. Unfortunately, it took about 4 years to get the Comet IV redesigned and off the ground. By that time, instead of competing with DC-6s and Lockheed 749 Constellations, it was competing with the Boeing 707 and the Douglas DC-8. At that point, it was too slow, and too short-ranged. (Pan Am 707 used to take off about a half-hour after BOAC Comet IVs, and they made a point of announcing when they passed the Comets somewhere between Iceland and Greenland. With a modified Fueselage it of course became a great maritime patrol aircraft known as the Nimrod. Nimrod is apparently superior than the Orion: at least as far as the airframe is concerned. Nimrods are a bit faster than P-3s. That's not really relevant though, when looking for submarines. They're both big enough, fast enough when need be, and slow enough when need be. Being slow enough is very important for those types of planes. The Orion beats in wrt fuel consumption, The efficiency of the sensor suites is about equivalent, with a little seesawing back & forth depending on what point in time you're comparing the two. It's kind of ironic that the Orion also grew out of a semi-successful 1950s airliner with a troubled beginning - the Lockheed L-188 Electra, the fastes of the Western prop-driven airliners (The Tu-114 can beat it) L-188s also suffered a spate of mysterious crashes. In their case, it was a resonant vibration in damaged engine mounts that induced fuilure in the wing spar. Like the COnet, it got fixed (A bit more quickly - they didn't have to redesign the entire airplane), The Electra was hardly a plane making history and catapulting technology as was the Comet. The lessons from the Comet, the most extensive research into one plane and metal fatigue ever, were used on virtually every plane after in some way or other. but it took time to rebuild public confidence, and the introduction of pure jets on U.S. Domestic routes killed off demand. The burried engines ( speys and now BMW/Rolls Royce BR715 ) provide a significantly reduced radar signature. (Here lies the disadvantage of burried eingines: installing high bypass ratio engines required re-engineering of the wing roots) Not really. The fan sections are entirely exposed within the ducts, and they're spinning pretty fast - that makes the return scintillate, which makes it easier to pick out of clutter, if you know how to look at it. With that big honkin' wing, and the large, slab sided fuselage, even if it was a bit less obvious, it's a distincion without a difference. The engines which are close to the fueselage mean that opperation with engines shutdown does not create significant asymetric thrust problems. Indeed opperation on 2 engines is I believe normal on long loitering patrols. Asymmetric operation with an Orion isn't much of a big deal, either, although it can be a handful in some circumstances. Remember that it had to be able to climb out on 3 engines on takeoff, with a load of passengers aboard. Early on, it was policy on teh P-3 to patrol on 2 engines. The occasional difficulty in getting them both started again, and the need to have as many alternators running a possible to supply th electrical buses has changed that so that they only cage 1 engines. (The last I heard - one of my former bosses was a Navy Reserve P-3 Pilot) The latest Nimrods I believe have a range in excess of 6500nm and can launch cruise missiles. They can be armed with sidewinders and presumably AMRAAM style self homing missiles is a possibility. P-3s are good for about 4500 NM, including 3 hours stooging around at 20,000', and 1 houf chasing contacts at 200', with a 10% reserve. As for what it carries, we've got all teh Cruise Missile carriers the START Treaties will allow. (That's what happens when you're a Major Nuclear Power ) So we can't fit Tomahawks or ALCMs. However, it will carry a whole raft of Harpoons & SLAM-ERs, which are Cruise Missiles of a somewhat more subdued nature. I don't recall if anybody's stuck a Sidewinder on a P-3, but there's no reason why you can't. A SIrewinder requires a standard rack to fit the rail to, soem wires to wake it up, and some wires to insert the seeker's growl into the intercom system. AMRAAMs are right out, for either. While an AMRAAM has an active seeker, it still needs a fighter-type Fire COntrol System to properly program it before launch. With the correct systems and sighting they might even provide the RAF with a mini B52. The big wings must provide good altitude performance. As for the Nimrod being a mini-B-52, well, we've got B-52s to fill that role. His point is that it can be used for other functions too, which is cost effective. B52/Vulcan types of planes cost a "fortune" to make and maintain - 40 million people in the USA are excluded from medical care, make the armed forces more efficient and your people, benefit. The Nimrod was fitted with sidewinders during the Falklands war. |
