Aerothermodynamics,erodynamic forces and moments, and the heat flux are crucial parameters driving the vehicle performance. Modelling the aerothermodynamic properties of re-entry vehicles is a highly complicated and multidisciplinary problem. For conceptual design optimization, incorporating a high-fidelity analysis i

Numerical Interpolation,hicle surface from these points requires an interpolation algorithm. In this work, we use cubic splines and spline surfaces as the interpolation scheme. In this chapter the basics of these methods, as well as some issues pertaining to their implementation, are discussed. The splines and spine surfac

Vehicle Geometry,hods by which we parameterize these vehicle shape, e.g. the manner in which we relate the shape parameters that are to be optimized to a continuous vehicle shape. The capsule is defined by a combination of basic geometric shapes: sphere segments, a torus segment and a conical frustum. The winged veh

Optimization,hm. In this chapter, we start by discussing the general problem of both single- and multi-objective global optimization, followed by a discussion of the PSO method, including the approach we use to for multi-objective optimality and constraint handling. Finally, we show how the optimization algorith

1869-1730 ive text provides a crucially valuable reference for concept.This book covers the parameterization of entry capsules, including Apollo capsules and planetary probes, and winged entry vehicles such as the Space Shuttle and lifting bodies. The aerodynamic modelling is based on a variety of panel metho
