Abstract

The early stages of a space mission design are crucial for the development of the whole project because they strongly influence the ensuing design phases. Moreover, feasibility assessment at early stages brings to time and cost reductions and strongly determines the overall performances of proposed solutions. Concurrent Engineering (CE) is a systemic and systematic design strategy that employs real-time interdisciplinary activities for products development. The advantage of the CE approach is particularly noticeable in the study of systems of high complexity, as space exploration systems do. The aim of this work is to show how a Concurrent Design approach can be very profitable in the development of a pre-phase A study of an interplanetary space mission, by means of a greater and effective exchange of information, enlarging the solutions tradespace, highlighting system criticalities and solving inter-subsystems conflicts. The case study, TRIton Tomography Orbiter (TRITO), is conceived as a mission to investigate the Neptune planetary system and its main moon Triton, which is of scientific interest due to its geological activity and the possible presence of subsurface oceans. The possibility of a pre-science phase in orbit around Neptune has been considered, giving the opportunity of precise measurements of its gravitational and magnetic field, together with its upper atmosphere composition. Therefore, a complex suite of instruments composed of magnetometers, laser altimeters, cameras and spectrometers, constitutes the payload, supported by a spacecraft able to face challenging environmental conditions during its whole spaceflight, ending with an aerocapture manoeuvre within the Neptune atmosphere. The collaborative approach, through the use of a modern CE design tool, is demonstrated to be very helpful not only in finding solutions meeting the strict constraints imposed by the harsh environmental conditions, but also for the individuation of optimum solutions related to mission analysis and mass budget aspects according to the system criticalities. The CE approach has been demonstrated to be an unavoidable design methodology for the development of systems showing a high-level of subsystems interconnections and simultaneous interactions of different engineering domains, permitting to manage the growing design complexity.
