which aircraft has a most strength in stresses and can be abused..? Boeing or Airbus?

i'm really curious about this...

i know that all of the airline aircraft are not designed in a acrobatic maneuver..

but when it comes to safety...specially the strength,

to the structures,

which aircraft can survive if overstressed has done...

if unexpected events may happend or intentionally done by the pilot??

e.g, barrel roll, reaching the supersonic speed or speed of sound, bank angle of 90 to 180 deg. maximum RTO without blowing the tires, and without using the thrust reversers/spoilers

stiff climb and rapid descent, overweight landing, fast landing..

using the flaps above the normal speed,

which aircraft will survive most in this kind of maneuver...

    It depends largely on the model.

    Typically Boeings are designed to be more damage tolerant than an Airbus. This is partially due to their origins (Boeing built war planes).

    This is also due to their intended life-design. If you have a look historically, the 727 and 737-100/-200 have exceeded their intended life design by a number of years. This is due to a continuing airworthiness maintenance program, and a well designed aircraft. There are exceptions like the Aloha Airlines accident. They actually learned from that and put a whole new maintenance program in place to avaoid that problem called corrosion prevention and supplemental structural inspections. There was alson an airworthiness directive (AD) put out by the FAA to inspec the lap seams on that type aircraft. If you look at one today, often you will see huge button head rivets down the lap seam of the aircraft (where it came apart on the Aloha).

    However, the 757 is a shining example of how not to do it. In the industry, the fuselage is referred to have O-too-thin skin. It dents easily since the skin is made from a thinner material than other Boeing aircraft.

    Airbus for a number of years built aircraft, but had difficulty with the Structural Repair Manuals because they just didn't have enough experience to publish a reliable manual. One had to go to them to work up a repair scheme that with Boeing was readily available in the manual.

    Airbus is now past that stage, but I still have the personal belief that since they are interested in cheaper-than-Boeing sales, they cut costs wherever possible (structurally) and call it a "life-design" limit. They don't expect or want to see first generation A300 or A320 aircraft around after 30 years.

    Stress can bring a plane down, its a know fact. That is why most aiplanes have an overspeed alert that tells the pilots that there is too much wind moving around the wing. When this happens the wing creats a lot of turbulece in the vortex that passes behind it, and starts to shake and bend. Different planes are built differently but usualy the bigger once such as the Boeing 747-400 or the A340-600 have longer wing span and can flex easier. However I know for a fact that the Boeing 777-300 has the most complex wing of any aircraft to this day. During its testing the stress the wings can handle they flexed around 30 degrees. Anyone who knows anything about planes can tell you that is a lot of stress but the wing didnt snap untill then. This type of stress is almost impossible to happen because you would need some day after 2maro weather in which case all planes would be grounded. But to answer the question i would have to say that the Boeing 777-300 is one of the best for not stressing too much.

    Hope this helps

    Engineers design airplanes that exceed the normal stresses and limits. See the link for the 777 wing stress test. The wing exceeds it normal limits by 150%.

    I have seen more Boeing tests than I have seen Airbus tests but I am not assuming that Airbus does not take stress testing lightly by any means. I'm sure the stresses on the A380 are tremendous. Did you see those wings flex on landing? But again, this is all taken into consideration when the aircraft is designed and built.

    Now which model could be out-stressed out more. That is a question that we will probably never know. I guess if you had a computer model and could figure out a virtual stress test for each. All aircraft have limits. As the saying goes, a chain is only as strong as it's weakest link.

    * i believe some or many of those test had been by the maker themself. And of course they kept the results for their own records

    * engineers give about 20 to 60% overload/safety factor to different parts of the airplanes.

    * of course those rigorous test can be done, but, you're talking about damaging/destroying an object with a 25-250 million dollars price tag (or more), so somebody has to pay for it.

    * one way to know is to see all the records of aircraft accidents, start from the 50s-60s, human error or mechanical failures or other causes.

    * being objective, both Airbus and Boeing should have about the same strength, they dont want to put their brand image into risk, because airplanes are designed to carry people safe and sound (and comfortably)

    * if i'm not mistaken, recent months(or 1-2yrs), Airbus surpass Boeing in terms of sales (i think it's a small difference in sales though)

    * besides Airbus & Boeing, there are other players, like BAe, Ilyushin, Embraer, etc

    You can tell the Americans who are replying to this question. Get over this American is better fixation. Both US aircraft manufacturers and the FAA have condoned poor design for a long time in various aircraft but in saying this it has happened in Europe as well, so not so good on both sides.

    Generally you would find that for both manufacturers that they produce very strong and sound airframes when they are NEW. Maintenance is the key and it is generally something else giving way (ie engine explosion, explosive decompression etc that may tear up the frame beyond reasonable limits) though Beoing had the fun with the cargo doors (remember United) that was a design error though it must be admitted in that case and in the Aloha incident the airframe did stay together despite significant damage to the aircraft. Airbus has tended to steer clear of structural errors and has specialised in such things as haveing the computer turn the plane upsidedown and put it in the ground.

    Things like the tail falling off the plane have tended to be a specialty of American made aircraft but remember they were blamed on maintenance so the manufacturers were in the clear. If you fully maintain an aircraft it could technically last forever but this would be prohibitavly expensive to most users. For those one eyed Boeing supporters out there they have been around longer and have been through more "incidents" and survived however Airbuses are designed to not get into these situations. Also if you are into quoting pure stats to make your point you could not dispute that more Boeings have fallen out of the sky than Airbuses.

    Airbus aircraft has computers that limit how much an aircraft can pitch up, bank to the side etc. It is very difficult to put it in a position where you can overstress the airframe unless given an abnormal situation.

    Boeing planes in my opinion are sturdyer. A couple of 727 are known to have pulled out of nosedives and rolls, an Air China 747 was moved around like an acrobatic plane over the pacific the 707 was rolled over etc

    the useful life of a Boeing aircraft is longer than a Airbus so I would think that a Boeing would take more stress. Tex Johnson did a roll in a 707. a good pilot can do alot of maneuvers and not stress. the aircraft. have you seen any film of how BOB HOOVER. he could do all kind of maneuver. he could do rolls ,loops with a glass of water and not spill any during the maneuver.

    The correct answer is Boeing. The reason is Boeing aircraft meet all the certification rules under FAR 25. Not all Airbus meet all the FAR 25 rules that’s why not all Airbus’s are allowed to hold FAA N-numbers. Some Airbus will have a waiver from some of the rules. U.S. standards say the safety factor for all U.S. aircraft will me 1.5. Some other aircraft manufactured in other countires have a safety factor of 1.2 to 1.3

    I believe the Boeing to be more sturdy and capable.

    But whether you do those fancy tricks in an Airbus or a Boeing, I'm certainly not going to be a passenger on that ride.

    Source(s): 1) Boeing been around like forever, so they know what they are doing. 2) American Design, American Made, and American ingenuity.

    Airbus has tendency to break down a lot, read the airplane news. And almost every airline in the U.S. has a Boeing airplane and those rarely ever go wrong.
