At least in aerospace, the 2,000 hr spec comes up often as a reasonable service life. We could make everything last forever, but that usually means beefier, heavier parts. How much more in fuel per flight hour are you willing to pay for a product that lasts longer? What about decreased range? Also, how much of a unit cost increase will you accept to pay for larger chunks of aerospace aluminum? Tradeoffs are necessarily driven by consumer demands.
- saiya-jin 9y agoI will happily accept extra 20 kg weight on my 1500 kg car, if it means 10 most mechanically stressed parts in engine, suspension, transmission etc. will last much longer. that maximum 0.1l/100km consumption increase will be perfectly fine with me too, most people don't drive for fuel efficiency anyway (that would mean 90 kmh on highway for example).
