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作者: Misgiving 時間: 2025-3-22 05:54
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作者: CULP 時間: 2025-3-22 10:43
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作者: overweight 時間: 2025-3-22 13:05
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作者: overweight 時間: 2025-3-22 20:28 作者: 袋鼠 時間: 2025-3-23 00:26 作者: amygdala 時間: 2025-3-23 04:54 作者: 奇思怪想 時間: 2025-3-23 05:34

Finally, we present the models that re used for the guidance of the capsule and winged vehicles. Both vehicles use similar bank angle modulation (designed to prevent skipping entry), but distinct angle of attack modulation.作者: 彩色 時間: 2025-3-23 20:20 作者: Carminative 時間: 2025-3-24 00:16 作者: Dedication 時間: 2025-3-24 04:46 作者: FRAX-tool 時間: 2025-3-24 06:39

Numerical Interpolation,e. In this chapter the basics of these methods, as well as some issues pertaining to their implementation, are discussed. The splines and spine surfaces are presented in both Hermite and Bézier formulation, and the link between the two is used to enforce that the spline surface net shows neither concavity nor self-intersection.作者: 虛假 時間: 2025-3-26 10:57 作者: 能夠支付 時間: 2025-3-26 13:45

Instead, we use local inclination methods for the aerodynamic behaviour, and analyze the heating of the vehicles only at key areas using (semi-)empirical relations. In this chapter, physical background of relevant aspects of hypersonic flow is reviewed, and the mathematical modelling approach we take here is presented.作者: 杠桿支點 時間: 2025-3-26 20:07
