How heavy are the blades from

  1. Turbofan (CFM56-5B, RRTrent800, PW4062A) and
  2. Turboprop (PW127M)


Is there a general appromixation like $$ m_\mathrm{Fan} = 0.1 \times m_\mathrm{Turbine} $$ as well?

After doing some light research, I found that the Turbofan CFM56-5B2 has a dry weight of 5250 lb (2380 kg). I wasn't able to find the exact weight of the PW127M, but the approximate weight is 390.5–481.7 kg.

Unfortunately, I wasn't able to find an answer for your general approximation formula.
