Complex Subject

Abstract The aircraft design is a complex subject since several and completely different design disciplines are involved in the project. Many efforts are made to harmonize and optimize the design trying to combine all disciplines together at the same level of detail. Within the ongoing AGILE (Horizon 2020) research, an aircraft MDO (Multidisciplinary Design Optimization) process is setting up connecting several design tools and competences together. Each tool covers a different design discipline such as aerodynamics, structure, propulsion and systems. This paper focuses on the integration of the sub-system design discipline with the others in order to obtain a complete and optimized aircraft preliminary design. All design parameters used to integrate the sub-system branch with the others are discussed as for their redefinition within the different detail level of the design.

Abstract This investigation focuses on the development of modifications to the Collaborative Optimization (CO) approach to multidisciplinary systems design, that will provide solution capabilities for multiobjective problems. The primary goal of this research is to provide a comprehensive overview and development of mathematically rigorous optimization strategies for MultiObjective Collaborative Optimization (MOCO). Collaborative Optimization strategies provide design optimization capabilities to discipline designers within a multidisciplinary design environment. To date these CO strategies have primarily been applied to system design problems which have a single objective function. Recent investigations involving multidisciplinary design simulators have reported success in applying CO to multiobjective system design problems. In this research three MultiObjective Collaborative Optimization (MOCO) strategies are developed, reviewed and implemented in a comparative study. The goal of this effort is to provide an in depth comparison of different MOCO strategies available to system designers. Each of the three strategies makes use of parameter sensitivities within multilevel solution strategies. In implementation studies, each of the three MOCO strategies is effective in solving two multiobjective multidisciplinary systems design problems. Results indicate that these MOCO strategies require an accurate estimation of parameter sensitivities for successful implementation. In each of the three MOCO strategies these parameter sensitivities are obtained using post-optimality analysis techniques.

The Impact

Advanced Manufacturing is widely used with features and applications playing a game changing role in our daily life. The European Space Agency has initiated in April 2016 a multi-disciplinary approach exploring the impact of infusing Advanced Manufacturing into space practices. A Concurrent Design Facility study was performed investigating potential design methodology amendments produced by introducing Advanced Manufacturing techniques into the design space. Innovative materials and processes were added to the conventional design parameters usually populating the systems design trade-spaces. This enabled multifunctional solutions, previously inconceivable, with a redefinition of interfaces and related requirements, shifted from ‘discipline’ boundaries to ‘units’ or ‘assembly’ boundaries. The Concurrent Design Facility Study identified the core domains of expertise required in a ‘Design for Advanced Manufacturing’ frame, governed by a flexible, open-minded systems engineering coordination. Early involvement of material and process engineers in the design proved to be an essential ingredient of the ‘Design for Advanced Manufacturing’ recipe. The design freedom brought by Advanced Manufacturing calls for unconventional design solutions, creativity becomes a need and infusion from non-space is invaluable. Biomimicry and architecture principles enriched the concurrent design environment, which proved to be very well suited with the needs and objectives of the new design methodology. This article reports the Concurrent Design Facility study conduct, as first attempt to understand Advanced Manufacturing impact on design methodology, the study cases selected for analysis, the observations on the methodology and on the interactions among the specialists in the team. The study outcome is reported, including an overview of benefits, disadvantages and points for further investigation in relation to the study cases assessed. In addition, the paper proposes recommendations for injecting Advanced Manufacturing into the project life cycle, from early design up to procurement phases and ultimately to the assembly, integration and verification phases, indicating required modelling tools, technologies and redefined engineering roles and expertise.

Aircraft Performance

The present work describes an aircraft design methodology that uses the wingspan and its mean aerodynamic chord as main design parameters. In the implemented tool, low fidelity models have been developed for the aerodynamics, stability, propulsion, weight, balance and flight performance. A Fortran® routine that calculates the aircraft performance for the user defined mission and vehicle’s performance requirements has been developed. In order to demonstrate this methodology, the results for a case study using the design specifications of the Air Cargo Challenge 2013 are shown.

The Cost

In Italy in 2020, only 15.5% of school building heritage was retrofitted from an energy and environmental point of view. In this paper, the cost-optimal method was applied to two different school buildings belonging to the same Italian cold climate zone but characterized by different structural and technological solutions. The research aims at defining the cost-effective redevelopment solution among several ones proposed to apply to this building type. At the same time, this paper provides a critical analysis of the methodology applied, highlighting deficiencies related to a not proper evaluation of environmentally friendly retrofitting measures. In a cost-effective context, the main results show that the intervention on the heating system is more convenient than the retrofitting of the envelope. The energy saving is equal to about 35% for both considered schools. Among the different proposed requalification configurations, the adoption of PV (photovoltaic) electric generation is included. In this regard, an optimization procedure was implemented in a generative design environment to maximize energy production with reference to different design parameters. As a result, a solution with south oriented PV modules with a tilt angle of 42° and arranged in 0.7 m spaced rows proved to be the most effective.
