I am very conscious of the great honour of being invited to deliver this fourth Reynolds-Prandtl Lecture. At the same time, I am very pleased. As far as I am concerned, the spirit of these two great scientists is still alive. They are both with me every day—at least, I have pictures of them in my office and I look at them every day.

Optimal aircraft design is impossible without a parametric representation of the geometry of the airframe. We need a mathematical model equipped with a set of controls, or design variables, which generates different candidate airframe shapes in response to changes in the values of these variables. This model's objectives are to be flexible and concise,

Simulation based aerodynamic design
2000 IEEE Aerospace Conference. Proceedings (Cat. No.00TH8484), 2002This paper reviews the status of advanced computational simulation techniques in the aerodynamic design of modern aircraft. An outline of the aircraft design process is provided, and the most relevant trade-offs between disciplines are presented to justify the leading role that aerodynamic design plays in this truly multidisciplinary process. A control

Computational aerodynamic design methodology
Applied Aerodynamics Conference, 1983The transonic wing design process has been vastly improved at Lockheed-Georgia. The revised design procedure enhances useability and reliability by combining numerical optimization and inverse design into a single wing design code with transonic analysis provided by a modified version of FLO22.

The performance criterion for engine power for aircraft of the Skyvan type is related to the single engine climb gradient in the en route configuration. The required engine power (M.C.P.) was specified such as to give a payload capability of 3,500 lb. at an ambient condition of ISA plus 20 deg. C. By use of such a specification the effects of different

Aerodynamics, the study of the behavior of air as it interacts with solid objects, is a crucial field of study that underpins the design and operation of various vehicles and structures. Its principles are central to the fields of aerospace engineering, automotive design, civil engineering, and even architecture.

Aerodynamic design via optimization
Journal of Aircraft, 1992An aerodynamic design optimization method is presented that generates an airfoil, producing a specified surface pressure distribution at a transonic speed. The design procedure is based on the coupled Euler and boundary-layer technology to include the rotational viscous physics which characterizes transonic flows.

Optimum Design in Aerodynamics *
IFAC Proceedings Volumes, 1983Abstract We use optimal control methods to solve a free boundary constrained problem. The boundary is considered as a control ; the constraint is written as a criterion that we must minimize. But we cannot already hope to demonstrate the existence and uniqueness of a solution to this problem, since the existing theories only consider a convex ...

Computational Aerodynamic Design Optimization
Volume 6: Turbo Expo 2003, Parts A and B, 2003Quasi-1D Euler equations have a considerable part of research to allow the prediction of the internal and external flows of the aerodynamic applications. Numerical solving of these equations by a so-called computational fluid dynamics (CFD) finds a very close agreement of the flow solver regarding to the experimental tests. Using CFD in the aerodynamic
