As usual, however, the only way to really understand the efficiency and effectiveness is in the long run. But the materials used presently are an improvement over prior years and hopefully the curve towards even better ones will continue.<br /><br /> My understanding is that ceramics have been widely used in many forms including body armor and they may be more advanced in engine parts as they have been used in racing cars enginesAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-64787300213926935452012-05-24T10:47:15.540-04:002012-05-24T10:47:15.540-04:00I am not an expert on the material sector, but I a...I am not an expert on the material sector, but I am not aware of any that would be superior to the ceramics. There are some "powder" materials under consideration or in lab testing that could probably be as good as ceramics.aeroturbopowerhttps://www.blogger.com/profile/17686461923667604678noreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-79692675354156936942012-05-23T13:23:23.632-04:002012-05-23T13:23:23.632-04:00Besides ceramics, are there any other materials wh...Besides ceramics, are there any other materials which could be incorporated into the engine that would alleviate this issue.

They are costly - no doubts. But the most important question is: are they ready? Until now they are not, according to my information.aeroturbopowerhttps://www.blogger.com/profile/17686461923667604678noreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-61351543937995296382012-05-22T14:46:39.557-04:002012-05-22T14:46:39.557-04:00Will the use of ceramic parts and or coatings comp...Will the use of ceramic parts and or coatings compensate for this factor?

So, depending from where they started, it could still be withing that range. Also, I read someone mentioned that the fan diameter increased did not add much (apparently, that person saw a slide presented by Boeing)to the Boeing Max efficiency (weight and drag penalty). Does it have more to do with engine maintenance (core temperature less hot)and also less engine noise?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-73734568599772474942012-05-20T06:28:10.422-04:002012-05-20T06:28:10.422-04:00Bittersweet maybe...?Bittersweet maybe...?aeroturbopowerhttps://www.blogger.com/profile/17686461923667604678noreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-15310657053136755472012-05-20T00:24:46.250-04:002012-05-20T00:24:46.250-04:00The "sweet spot" wasn't so sweet aft...The "sweet spot" wasn't so sweet after all, was it?Anonymousnoreply@blogger.com
