Self-designing parametric geometries
Self-designing parametric geometries
The thesis of this paper is that script-based geometry modelling offers the possibility of building `self-designing' intelligence into parametric airframe geometries. We show how sophisticated heuristics (such as optimizers and complex decision structures) can be readily integrated into the parametric geometry model itself using a script-driven modelling architecture. The result is an opportunity for optimization with the scope of conceptual design and the fidelity of preliminary design. Additionally, the proposed `self-design' philosophy of using an integrated design heuristic to construct much of the geometry is a good mechanism for de-constraining the design space, as we can take the design variables as a starting point from which we generate a feasible design, wherever possible. We illustrate these ideas through the parametric geometry model of a twin-engined light aircraft.

Abstract
The thesis of this paper is that script-based geometry modelling offers the possibility of building `self-designing' intelligence into parametric airframe geometries. We show how sophisticated heuristics (such as optimizers and complex decision structures) can be readily integrated into the parametric geometry model itself using a script-driven modelling architecture. The result is an opportunity for optimization with the scope of conceptual design and the fidelity of preliminary design. Additionally, the proposed `self-design' philosophy of using an integrated design heuristic to construct much of the geometry is a good mechanism for de-constraining the design space, as we can take the design variables as a starting point from which we generate a feasible design, wherever possible. We illustrate these ideas through the parametric geometry model of a twin-engined light aircraft.
