AeroFlot Flight 8641 Crash Analysis
AeroFlot Flight 8641 Crash AnalysisMost people think of tied(p)s as a fast and efficient way to get to a place farther away than what a car can take them. But, what most people dont ac fuckledge is that there are engineering propose problems. One of which happened to Aeroflot Flight 8641.In June 28, 1981, AeroFlot Flight 8641 encountered an engineering design problem. Unfortunately, it ended horribly and the force killed every maven on lineup which was a total of 132 people. The skim crashed near Mozyr, Belarus. This opened the peoples eyes well-nigh the Yak-42s. All Yak-42s were suspended from service until the design defect was solved and tested.Yakovlev is a plane company out of Russia.In 1965, Yakovlev built the Yak-40. Then in the early 1970s the Yak-42 was designed and built. The designers are working on a forward-looking plane design called the Yak-44. The Yak-42 is a medium size jet airliner. AeroFlot Flight 8641 was the first crash with this plane because of the desig n failure. This crash was the first and deadliest crash including the Yak-42. No one knew about the design defect until the investigation on why the plane lost control and crashed.1During the investigation, it was found that the whole tail of the plane detached due to metal fatigue on the jackscrew. 3The metal on the jackscrew was melted, which made it deform and cause a weak spot in the tail. The pressure of the air and move of the plane started cracking and breaking the tail off, which cause the plane to dive down to the ground and crashed killing everyone on board.The designers were a group from the company, Yakovlev. They were blamed for the crash because they didnt take precautions on metal fatigue issue in the prototypes4. After the crash, the designers had to fix the problem before sending any more planes up into the air. So, the designers had to run across a way to stop metal fatigue.New precautions were put into place on how to keep the jack screw from melting.6 The desi gners needed to know parts of geomorphological engineering, mechanical engineering, and material science.7 They needed to know how to keep the stress below the fatigue level and also, needed to know how to refer the plane efficient when one part fails the whole plan does not fail.8 They also had a part life9. This is when a part got used to a certain amount of time it got replaced with a new one. And lastly, the plane was checked for cracks and when a crack gets to a certain length the part is replaced.The jackscrew is made out of cast iron. This cast imprisonment melting point is 2060-2200 degrees fahrenheit or 1127-1204 degrees celsius. The solution of the new design is how to divert the heat from the jackscrew or change the material of the jackscrew or the materials around it to keep the jackscrew cooled of10f.The design of the Yakovlev Yak-42 was the cause of the crash. The designers had to make a new design to solve the problem that happened to AeroFlot Flight 8641. There we re also new precautions put into place to prevent crashes or issues with the plane. New part lifes were also introduced to keep the planes running for longer and to keep old parts off the plane to cut off the chance of it failing and causing a crash.https//en.wikipedia.org/wiki/ screw jackhttps//en.wikipedia.org/wiki/Fatigue_(material)https//www.revolvy.com/ important/index.php?s=Aeroflot%20Flight%208641https//en.wikipedia.org/wiki/Aeroflot_Flight_8641http//www.theinfolist.com/php/SummaryGet.php?FindGo=Yakovlev%20Yak-42http//www.airvectors.net/avyak40.htmlAeroflot flight 8641Jackscrewhttps//en.wikipedia.org/wiki/JackscrewMetal fatiguehttps//en.wikipedia.org/wiki/Fatigue_(material)https//www.revolvy.com/main/index.php?s=Aeroflot%20Flight%208641Jackscrew mechanism in the aircrafts tailThe aircraft lost control and dove into the groundhttps//en.wikipedia.org/wiki/Aeroflot_Flight_8641Killed all 132 people on boardWhenJune 28, 1982WhereNear Mozyr, BelarusHowJackscrew mechanism in the air crafts tailWhat happened afterAll yak-42s were shut down until the problem as fixedYakovlev Yak-42The tailplane detached from the planehttp//www.theinfolist.com/php/SummaryGet.php?FindGo=Yakovlev%20Yak-42Rubric judge submitted on 12/21/2016, 115636 AM by emailprotected1050Title Page Your ca-ca 5xPresentnot through with(p)Table of Contents Your score 5xPresentnot makeAbstract Your score 5Presentnot make fundament Your score 5xBackground Your score 5Presentnot doneInvestigation Your score 6Presentnot doneFindings Your score 7Presentnot doneImpact Your score 0Presentnot doneConclusion Your score 5xnot doneReferences Your score 10References includedno referencesNotes Your score 10Notes recordedno notes6 Content Pages Your score 3 change 6 pages3 content pagesno contents pagesCommentsRubric rating submitted on 12/21/2016, 121440 PM by emailprotected1050Title Page Your score 5xPresentnot doneTable of Contents Your score 5xPresentnot doneAbstract Your score 5Presentnot doneIntroductio n Your score 5xBackground Your score 5Presentnot doneInvestigation Your score 7Presentnot doneFindings Your score 8Presentnot doneImpact Your score 5Presentnot doneConclusion Your score 5xnot doneReferences Your score 10References includedno referencesNotes Your score 10Notes recordedno notes6 Content Pages Your score 3filled 6 pages3 content pagesno contents pagesComments1how long did they make these planes? were there any other problems before this incident? where were they made? Did the company make any other planes?2describe HOW the accident was investigated how did they figure that out?3What is a jack screw and what does it do? Why does a plane need it?4Were there problems during testing, that were unattended? what is metal fatigue? what happens to metal as it is failing?5Findings?Who was at fault, what caused the accident, what future precautions were recommended?6is melting the same as metal fatigue?7why do they need to know these things and what do they need to know about these things?8Were they able to do this? is that the way they are design currently that if something fails, like a tail breaking, that they can exempt fly/land the plane?9is this a precaution or a new practice?10which one of these did they do? did they try both and decide on one? what are the advantages and disadvantages of one method or the other?11missing a section?
