The hunt for info on CFM56 engines Engine in NY street on 9-11 (20010911) said to be a CFM56 as used in Boeing 737s, NOT a Boeing 767 engine as it should be from Flight 175 according to the official story. The engine 'disappeared' by the FBI (along with all other 911 plane parts) and never seen again. ----LINKS----- article: http://home.att.net/~south.tower/STengine1.htm http://www.airliners.net http://www.ncix.gov/history/CIReaderPlain/Vol4Chap1.pdf "the CFM-56 hot sections are identical to those used in the the engines that power the US F-16 and B-1B military aircraft." --------------- http://lofi.forum.physorg.com/911-Events---New-thread_7444-9200.html QUOTE (Capracus+Dec 11 2006, 10:46 PM) beijingyank, are your aviation mechanics airframe or powerplant mechanics? Please share the specifics on how these mechanics determined that the street engine was not a PW JT9D. Cappy, There were airframe, powerplant/engine, electrical, and avionics mechanics reviewing the photos. The avionics, electrical and airframe mechanics candidly admitted they could not tell. The engine mechanics with experience working with CFM56's claimed that even though the engine was pretty beat up, they could still identify it as a CFM56. When I pressed the issue as to how they were able to make their determination this was a CFM56, language barrier became an issue. Therefore, I'm pushing the issue up to the Civil Aviation University. Let's see what the professors fluent in aviation English come up with. --- Turbofan engine pics: http://www.aircraftenginedesign.com/cepics1.html CFM56-3 diagram: http://www.f-16.net/modules/PNphpBB2/files/cfm56-3.gif http://www.aircraftenginedesign.com/pictures/CFM56.gif [added] CFM56-3 Photo: http://www.albadawi.be/GRAPHIC/cfm56-3.jpg PWJT9D cutaway: http://www.aircraftenginedesign.com/pictures/JT9D.gif http://blogsimages.skynet.be/images/000/169/890_JT9D.jpg ------------- ENGINE TYPES, per plane model -------------------------- Boeing 737 models Boeing 737-100/200 1968 www.airliners.net/info/stats.main?id=91 737-100 - Two 62.3kN Pratt & Whitney JT8D-7 737-200 - Two 64.5kN JT8D-9As, 68.9kN JT8D-15s, 71.2kN JT8D-17s, or 77.4kN JT8D-17Rs Boeing 737-300 1984 www.airliners.net/info/stats.main?id=92 "The 737-300 is the first of the three member second generation CFM56 powered 737 family, which also comprises the stretched 737-400 and shortened 737-500."

Third Edition by Bill Gunston. Using language which will be easily accessible to non-engineers, the author explains the difference between gas-turbine, jet, rocket, ramjet and helicopter turboshaft engines. He traces their histories from the early days through to today's complex and powerful units, as used in the latest wide-bodied airliners and high performance military jets. Updated to include Boeing's stretched 747 and Sonic Cruiser proposals, of this popular history and 'how they work' guide. 280 b/w illustrations. 256 pages. ------------- 20091230 http://www.k-makris.gr/ em: makris63@yahoo.com : kostas_makris@k-makris.gr Thank you for visiting my web site.
