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.

Aircraft Engineering and Aerospace Technology, 1969
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

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 ...
