Calculates the empty fuselage mass for an electric stopped rotor including
seats, avionics, servomotors, ballistic recovery system, rotor and hub
assembly, transmission, and landing gear. Additionally incorporates
results of the following common buildup scripts:
fuselage,py
prop.py
wing.py
wiring.py
Originally written as part of an AA 290 project inteded for trade study
of the Electric Stopped Rotor along with the following defined SUAVE config types:
Electric Helicopter
Electric Tiltrotor
Sources:
Project Vahana Conceptual Trade Study
Inputs:
