> $3k/year for each 1kg added to the plane
sorry, offtopic, but this is an interesting number. Do you have a source for more on this? Most of the search hits I can find are discussing economics of spaceflight.
- greeneggs 12y agoUsually you find these kinds of figures in articles about 3D printing aircraft parts. For example, "By reducing an airplane’s weight by just one kilogram, an airline can save $1,300 in fuel costs per year, according to the [2011] IBISWorld report." [1] The 2014 report can be purchased here [2]. Of course, these numbers will depend on the kind of plane and its utilization, as well as fuel costs.
