Well there is little, but there is also some. There's a whole field of accelerated testing of components, by degrading various variables, e.g. increasing temperature, vibration, sounds, corrosive environment, materials, etc., and then using curves of exaggerated failure times to predict failure times under nominal conditions. (after making tons of models and analysis)
You can also improve your simulation (here the sky is the limit).
It really depends on the cost of mishaps and design failures, if it's high enough you can almost always improve design with additional expenditure.
- madeofpalk 8y agoAre you suggesting that Rolls Royce didn't know this?
- trhway 8y agoWell, they didn't matched the resonant frequency of the blades with that of the enfine vibration at high thrust. Probably didn't allocated enough people and resources for even such basic stuff.
- darkmighty 8y agoIt was just a comment on how it is possible to accelerate testing. I wasn't suggesting anything, just discussing and exchanging information. Whether they used this, it's probable, but to what extent only an employee could tell.
