It uses standard MSL physical connectors to allow the design of propulsion systems with other libraries like the Electrical Powertrains Library (EPTL) considering the effects of the flight mission on the performance. Being fully integrated into the MSL MultiBody environment, all potential of Modelica libraries can be utilized. +In this first release, two main topics are covered: + - Longitudinal dynamics of airplanes (fixed-wing) for designing a propulsion system considering the flight mission + - Full dynamics of multi-copter drones (rotating-wing) including the control system for mission planning and design of the propulsion system +The two areas share common models like propulsion or landing gear systems.
