Aerodynamic Design and Performance

Aircraft Engineering and Aerospace Technology, 1965
An Outline of the Basic Configuration and Aerodynamic Features of the Argosy including Performance and Flight Handling Qualities. THE basic concept of the Argosy as a medium‐size freighting aircraft with a large capacity fuselage of high cross sectional area and low freight floor defined to a large extent the shape of the aircraft.

Turbine Aerodynamic Design and Off-Design Performance

2005
The turbine component is the power generator in a gas turbine system. As briefly discussed in Chapter 12, within a turbine component, an exchange of mechanical energy (shaft work) with the surroundings takes place. In contrast to compressors, the total energy of the working medium is partially converted into shaft work, thus supplying necessary power ...

Unducted Fan Aerodynamic Design

Journal of Turbomachinery, 1987
A method being used to design unducted fans, which are counterrotating propellers with unusually high disk loadings, is described. The quasi-three-dimensional approach employed is similar to that used for ducted fan designs; it consists of a circumferential-average flowfield analysis followed by cascade designs that include secondary flow and sweep ...

Aerodynamic design with cfd

1991
Corporate average fuel economy (CAFE) regulations have placed a high priority on aerodynamic efficiency for automobiles. While the wind tunnel will continue to play a vital role, computational fluid dynamics (CFD) holds the promise of bringing aerodynamics into the design process much earlier and less expensively. On May 3, 1991 Gary S.

Computer-aided design: aerodynamics

The Aeronautical Journal, 1979
In recent years, there have been rapid advances in the development of theoretical methods in aerodynamics, particularly for transonic flow calculations. Many papers have been written on this topic. It is however appropriate that there should now be a paper that concentrates not so much on the methods themselves but on the use of the methods for ...

Aerodynamic Design ‐ Air Intake

Aircraft Engineering and Aerospace Technology, 1969
WITH a vertical take‐off aircraft like the Hawker Siddeley Harrier, the only ground attack/ reconnaissance jet V/S.T.O.L. weapons system in operational service today, the air intakes have a vital influence on design and performance. At lift‐off and landing they need to absorb an exceptionally large flow of air with minimum loss.

Direct Approach to Aerodynamic Design Problems

Journal of Applied Mechanics, 1981
“Direct” small disturbance approaches to inviscid aerodynamic “inverse” or “design” problems in two and three-dimensional, subsonic, supersonic, and transonic flow, are given which extend the stream function method of Chin and Rizzetta. Our shape solutions generally involve nonlinear differential equations of mixed type for scalar “streamlike ...
