Abstract : A process is developed to enable a multi-architecture vehicle modeling process. The process starts with the identification of off-the-shelf components available for the design of small UAS. These components are characterized experimentally and to some extent a library of component models is constructed. The library is not extensive at this point since only critical components have been included. These critical components have some attributes attached to them (e.g., number of cells and capacity for a battery, mass and maximum power for a motor, and maximum thrust for a propeller). The design mission of interest to the user is analyzed next to identify pertinent design constraints and to enable the sizing of a small size autonomous vehicle. This requires models in order to properly design and analyze the performance of vehicles of differing architectures. As part of this research, three architectures have been retained: a fixed wing architecture (FW), a multicopter architecture (x-COP), and a hybrid Vertical Take Off and Landing (H-VTOL) architecture. For each of these architectures, one or more variants have been proposed (three for FW, one for x-COP, and three for H-VTOL. Many more variants of these architectures can be added by the analyst by simply supplying appropriate vehicle data. Finally, the capabilities of the different architectures are quantified using some pre-determined metrics of interest. These capabilities are presented to the decision maker in a visualization and trade-off environment which enables an exploration of the design space as well as the carrying out of sensitivity studies.
