“…As a consequence, several researchers (1)(2)(3) have explored different inlet designs and identified the critical parameters to improve the airflow pressure and the overall aerodynamic features of the aircraft. Amongst these designs, the submerged inlet (also called the flush inlet) has attracted significant interest from researchers due to its unique architecture (4)(5)(6)(7)(8)(9) , especially for aircraft operating in the subsonic flow regime. Submerged inlets were first introduced in the early 1940s.…”

The research focuses on the design space optimisation of National Advisory Committee for Aeronautics (NACA) submerged inlets through the formulation of a hybrid data fusion methodology. Submerged inlets have drawn considerable attention owing to their potential for good on-design performance, for example during cruise flight conditions. However, complexities due to the geometrical topology and interactions among various design variables remain a challenge. This research enhances the current design knowledge of submerged inlets through the utilisation of data mining and Computational Fluid Dynamics (CFD) methodologies, focusing on design space optimisation. A two-pronged approach is employed where the first step encompasses a low-fidelity model through data mining and surrogate modelling to predict and optimise the design parameters, while the second step uses the Design of Experiments (DOE) approach based on the CFD results for the candidate design geometry to construct a surrogate model with high fidelity for design refinement. The feasibility of the proposed methodology is demonstrated for the optimisation of the total pressure recovery of a NACA submerged inlet for the subsonic flight regime. The proposed methodology is found to provide good agreement between the surrogate and CFD-based model and reduce the optimisation processing time by half in comparison with conventional (global-based) CFD optimisation approaches.

“…In this context, the term Data-Driven Design (DDD) is often associated with the use of any kind of data science algorithm supporting in some way a specific phase of the product development process. While the use of data science algorithms to create surrogate models is an established practice in detailed design since several years (see for Jeong et al, 2005;Zhao et al, 2007;Akram et al, 2010;Huang et al, 2011), the same cannot be said for the other stages of the product development process. This paper presents a systematic review of the scientific publications proposing the use of DDD methods in the 'concept development' stage of the product development process as described by Ulrich and Eppinger (1995).…”

Data-Driven Design in Concept Development: Systematic Review and Missed Opportunities

The paper presents a systematic literature review investigating definitions, uses, and application of data-driven design in the concept development process. The analysis shows a predominance of the use of text mining techniques on social media and online reviews to identify customers’ needs, not exploiting the opportunity granted by the increased accessibility of IoT in cyber-physical systems. The paper argues that such a gap limits the potential of capturing tacit customers’ needs and highlights the need to proactively plan and design for a transition toward data-driven design.
