AeroFlot Flight 8641 Crash Analysis

AeroFlot course 8641 Crash AnalysisMost race think of course of studyes as a fast and efficient way to get to a place farther away than what a car can take them. But, what most deal dont have is that there are engineering target problems. One of which happened to Aeroflot shoot 8641.In June 28, 1981, AeroFlot Flight 8641 encountered an engineering design problem. Unfortunately, it ended horribly and the dispel killed everyone on board which was a total of 132 people. The planer put ined near Mozyr, Belarus. This overt the peoples eyes about the Yak-42s. All Yak-42s were suspended from service until the design abandon was solved and tested.Yakovlev is a plane company out of Russia.In 1965, Yakovlev built the Yak-40. be designer in the early 1970s the Yak-42 was designed and built. The designers are working on a new-made plane design called the Yak-44. The Yak-42 is a medium size of it jet airliner. AeroFlot Flight 8641 was the first crash with this plane because of the design failure. This crash was the first and deadliest crash including the Yak-42. No one knew about the design take flight until the investigation on why the plane lost control and crashed.1During the investigation, it was show that the whole tail end of the plane detached due to alloy hold out 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 speeding of the plane started cracking and breaking the tail off, which cause the plane to steep down to the ground and crashed killing everyone on board.The designers were a group from the company, Yakovlev. They were cursed 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 than planes up into the air. So, the designers had to find a way to stop metal fatigue. smart precautions were put into place on how to keep the jack sc rew from break up.6 The designers ask to make out sections of structural engineering, mechanical engineering, and material science.7 They take awayed to know how to keep the stress below the fatigue level and in addition, needed to know how to make the plane efficient when one government agency fails the whole plan does not fail.8 They also had a part life9. This is when a part got utilize 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 irons melting point is 2060-2200 degrees fahrenheit or 1127-1204 degrees celsius. The solution of the new design is how to steal 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 prob lem that happened to AeroFlot Flight 8641. There were 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 move off the plane to cut off the chance of it failing and do a crash.https//en.wikipedia.org/wiki/jackscrewhttps//en.wikipedia.org/wiki/Fatigue_(material)https//www.revolvy.com/main/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, B elarusHowJackscrew mechanism in the aircrafts tailWhat happened afterAll yak-42s were shut down until the problem as wintryYakovlev Yak-42The tailplane detached from the planehttp//www.theinfolist.com/php/SummaryGet.php?FindGo=Yakovlev%20Yak-42Rubric order submitted on 12/21/2016, 115636 AM by emailprotected1050Title Page Your brand 5x depictnot makeTable of table of table of contents Your grad 5xPresentnot done con Your strike out 5Presentnot doneIntroduction Your stain 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 make full 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 5xPresentn ot doneAbstract Your score 5Presentnot doneIntroduction 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 accident? where were they made?
