“…A third approach has been developed to support structure design and manufacturing studies of control movables in the preliminary design phase. A KBE application, called parametric movable model (PMM) has been developed by van der Laan and van Tooren [25]. The PMM is a type of MMG focussed on the design of aircraft movables.…”

If the designer changes the length of the wing in the MMG input file, for example, such modification is automatically reflected in the generation of the outer surface model for aerodynamic analysis, as well as in the models for structural analysis and in the mould models used for tooling design [25].…”

This paper discusses structure and functionalities of a knowledge-based engineering (KBE) application, called multimodel generator (MMG), developed to support aircraft multidisciplinary design, analysis, and optimization. Designers can use the MMG as an advanced modelling tool to swiftly generate geometrical models of many and diverse aircraft configurations and variants, by combining and adjusting a limited number of parametric objects, called high-level primitives. Besides capturing the geometric aspects of the design, the MMG also has the capabilities to automate a large part of the lengthy and non-creative pre-processing activities involved in the design verification process. The proposed KBE application has demonstrated to be a valuable solution for some of the critical needs indicated by the multidisciplinary design and optimization community, namely a flexible and robust generative tool to increase the level of automation in aircraft design, including the development of novel configurations; the exploitation of high-fidelity analytical tools already in the early design phase; the management of the design activities across distributed networks of disciplines specialists.

“…This paves the way for adoption of established concurrent engineering paradigms within a software environment to achieve a more automated design process. Fully automated optimization and integration will require early and continuous use of Knowledge-Based Engineering (KBE) solutions that must be integrated over the various aircraft disciplines, including the disciplines that make up the design and manufacturing domains 1 . Over the last years, considerable progress has been made in establishing multi-disciplinary KBE solutions [1][2][3] .…”

The paper is associated with the integration of multi-disciplinary knowledge within a Knowledge Based Engineering (KBE)-enabled design framework. To support this integration effort, the KNOMAD methodology has been devised. KNOMAD stands for Knowledge Optimized Manufacture And Design and is a methodology for the analytical utilisation of multi-disciplinary engineering knowledge within design. The KNOMAD acronym can also be used to highlight KNOMAD's formalized process of: (

“…The design can be subjected to various analysis tools (aerodynamic, 15 structural, 16 aeroelatic, 17 acoustic 18 ) each based on a single representation of the geometry. The results of these modules can subsequently be used in flight mechanics tools to investigate performance and handling qualities.…”

This paper details a new software tool to aid in the conceptual design of blended-wingbody aircraft. The tool consists of four main modules. In the preliminary sizing model a class I estimate of the maximum take-off weight, wing loading, and thrust-to-weight ratio is calculated. This information is used together with an initial guess of the 30 design variables that to form a geometric model of the aircraft. From this geometric model four disciplinary models are derived: an aerodynamic model, a model of the wing box structure, a model for the cabin, and a model for the fuel tank. In the subsequent analysis module refined weight estimation for the operating-empty weight is being calculated, as well as the center-of-gravity shift during loading, the static margin, the main stability and control derivatives, and the harmonic range. In the last module, these analysis results are compared to 27 nonlinear constraints stemming from the top-level requirements and the aviation regulations. A gradient-based optimization routine is employed to find a combination of the design variables that satisfies all constraints while optimizing for harmonic range at constant maximum take-off weight. Between 20 and 60 iterations are required to achieve convergence. The tool has been set-up to allow for maximum configurational flexibility such as forward-swept outer wings, under-the-wing engines, and twin vertical tails.
