Description
This research introduces a novel multidisciplinary conceptual methodology for the
design and development of lunar pressurized rovers (LPR) for human exploration and
scientific activities on the Moon. This work addresses the emerging need for advanced
rover technologies at a time when interest in pressurized lunar vehicles is experiencing
a strong revival. The methodology contributes to addressing the limited focus that LPR
for lunar operations have received in recent aerospace engineering research. The
design process is initiated with a rigorous analysis and selection of top-level
requirements, target mission and constraints. These include considerations related to
available technological capabilities, the characteristics of launch vehicles, and the
challenges posed by the lunar environment. Following the requirements analysis, the
methodology proceeds to the evaluation of the general vehicle layout. Both internal
and external configurations are explored through comparative studies aimed at
identifying the optimal design that ensures operational efficiency, fulfillment of the
requirements, and adaptability to the lunar terrain. This phase is critical in balancing
the functional aspects of the rover with the practical limitations imposed by the mission
environment. Key components of the design framework include the primary structural
sizing, the selection of internal habitat subsystems, the mobility system definition,
comprising wheels, suspension, and powertrain elements, and the design of the
docking system for LPR coupling with permanent lunar bases. Each subsystem is
subjected to thorough sizing activities and mass estimation procedures, to achieve a
complete final design and defined layout for the LPR. The proposed approach is
inherently modular and interdisciplinary, allowing for the integration in the framework
of diverse physical characterizations, and of different levels of fidelity, such as vehicle
dynamics, terramechanics, and powertrain performance. This modularity facilitates
iterative refinements, enabling the design to evolve in response to emerging
challenges and new technological developments. In doing so, the methodology not
only ensures technical feasibility but also provides a scalable framework adaptable to
a variety of mission scenarios and requirements. By presenting this integrated design
framework, the research demonstrates that a structured, systems-based approach
can effectively address the complex challenges associated with the development of
next-generation LPR. The results indicate promising potential for enhancing human
lunar exploration capabilities and supporting long-duration scientific operations on the
Moon. This research is developed within the Space It Up! program.
