      • ScaledConstantThrustPropulsionModel

        public ScaledConstantThrustPropulsionModel​(double thrust,
                                                   double isp,
                                                   Vector3D direction,
                                                   String name)
        Constructor with min/max deviation for the scale factors. Typical usage is, for example, if you know that your propulsion system usually has an error of less than 10% then set the min/max to respectively 0.9 and 1.1.
        Parameters:
        thrust - the thrust (N)
        isp - the isp (s)
        direction - in spacecraft frame
        name - the name of the maneuver
