Deriving the modified Breguet range equation for a hybrid-turboelectric aircraft

September 8th, 2017, by Ben Brelje

Summary

  • Modifications to the Breguet range equation considering hybridization of energy storage are proposed
  • Payload-range charts are constructed to illustrate the impact of hybridization on airplane performance for a TBM 700-sized design using two different non-dimensionalizations
  • Simple, analytical expressions for the impact of technology and mission requirements on airplane weight are derived and explained
