It still took take the best part of 3 MONTHS to find that one weapon. A number of weapons have been lost in mid ocean incidents involving B-36 and B-47 aircraft and none were recovered. Keith I also remember in the late '70s when they lost an F-14 overboard from a carrier. They were even more worried about the Phoenix getting into Soviet hands (they didn't yet know that it would happen a couple of years later with the downfall of the Shah). They had to find both the F-14 and the Phoenix, which separated from the aircraft. Both were found, but only after a massive search that used both surface-based sonar (sidescan?) and the NR-1 and Alvin. |

A local fisherman told the USN that the bomb went down "there". The admiral in charge of the recovery told the fisherman to bugger off, "we'll find it". After several weeks of searching guess where the USN found the bomb. -- Jim carry on ----== Posted via Newsfeed.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeed.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= 19 East/West-Coast Specialized Servers - Total Privacy via Encryption =--- |

Strangely enough this missile could be retrieved by the a foreign government (Russia, China or France). It was publicly stated that NASA would NOT even try and recover the jet for budgetary reasons and would abondon it, it would give anyone retrieving the X-43 the following information (at the very least): - The materials neccessary for hypersonic flight (titanium, composites, etc) - The aerodynamic design - The engine design - Some of the onboard computer information if it is retrievable Thus MANY of the details of how to REPEAT this experiment can be GLEANED from simply retrieve the X-43 from the Ocean bed. This would be well worth the risk to any foreign power. So I think that was not the wisest idea .... Lets try and provide you with a a clue 1) The Pacific is BIG 2) The Pacific is DEEP 3) The missile is SMALL The X-43 would have hit the water at a fair clip and likely been bent and torn apart. The shaping is all important, to pretty tight tolerances and probably can not be determined from the remains of the X-43. If it could be determined, it would tell them the shape for a missile 12 foot long, scaling is not obviously linear. |

wrote: Has any other country had success with a Ramjet or Scramjet??? France tried Hypersonics in the 50s and failed I believe (wasn't it called the Griffon Aircraft). I have been following many new aerospace developments for a number of years (namely scramjets and aerospike rocket engines). Russia and France supposedly launched one on the nose of an SA-5. Russia supposedly flew a scramjet powered RV on a Topal a month or two ago. A few things that came to mind ... Why was the X-43 important? Firstly it is a PROOF OF CONCEPT. Hypersonic Aircraft via Scramjet is possible. Secondly it gives the MILITARY the ability to make advanced CRUISE missiles that can get to a target quickly. Hardly. The military is already going a different route with scramjets. The X-43A uses hydrogen fuel. The stuff the military wants to use uses hydrocarbon fuel (don't know if it's regular jet fuel) and uses it to cool the airframe and uses the airframe heat to breakdown the fuel molecules before feeding them into the engine. It's already been tested albeit in a wind tunnel. Not only that the X-43A's engine ran for a grand total of about seven seconds. That and the need for a big ass booster to get it to speed so the scramjet could start up makes it completely useless as a weapon. If anyone listed to the interview with the scientist on Friday (NPR/PRI), they said that if this test was successful, military applications would be the FIRST application. I think Space Shuttles and Commercial applications are still at least 20 years out. At the rate they're going I'd guess more like 30 to 40 years. Hell it will be 20 before a Shuttle replacement is flying. And that dinky space plane proposal they have out there is not a Shuttle replacement. Military apps may see the light of day in about 5-10 years, if needed they could be rushed out. The example used by the scientist was the Bin Laden sticking his head out of a hole and todays technology only able to hit the target in about 3-4 hours. With Hypersonic missiles, targets become much more targetable ... hmmm This missile was allowed to glide into the Pacific. Strangely enough this missile could be retrieved by the a foreign government (Russia, China or France). I doubt they'd bother. I'd be surprised if there were anything on the vehicle in the way of materials or geometry that isn't already well known and publicly available. The X-43 though is way cool, but I am trying to understand if using such an engine will enable an aircraft to enter space or even reach escape velocity ... someone help me out ... If you could make materials or come up with a way of cooling that would allow you to run up to orbital or escape velocity while in the atmosphere with enough extra for the coast out then sure. With the X-30 they were trying a lot of active cooling with LH2 and in the end they still figured they'd need a rocket to give it the final boost into orbit. They never specified how they were going to get to scramjet speeds in the first place with it. Look up "strut jet" if you want to see something that will get you from the ground to space with one engine. In theory anyway :-) |

Reference the Russia/France joint IGLA project: The following papers including the project IGLA (AIAA-2003-5250), can be found at the following website: 11th AIAA / AAAF INTERNATIONAL CONFERENCE Space Planes and Hypersonic Systems and Technologies AIAA-2002-5250 http://hypersonic2002.aaaf.asso.fr/received.html http://hypersonic2002.aaaf.asso.fr/papers/17_5250.pdf Some very interesting papers also appear on the website on the subject of hypersonic vehicles.
