QinetiQ GRC Data sheet – Paramarine Endurance The Endurance functionality within the Powering module allows endurance of a vessel to be analysed by specifying the operational profile, for either surface or subsurface vessels. The propulsion and associated systems are modelled by defining alternators, battery banks, diesel engines, diesel generators, electric motors, fuel cells and gas turbines which can be in turn wired up to diesel tanks or LOX storage tanks objects modelled within the design. A mission element outlines activities within a Submarine Propeller defined For any of the search methods,...
