A foil is an architectural device based on a symmetrical rendering of leaf shapes, defined by overlapping circles of the same diameter that produce a series of cusps to make a lobe. Typically, the number of cusps can be three ( trefoil ), four ( quatrefoil ), five (cinquefoil [ 1 ] ), or a larger number (multifoil). [ 2 ]
The dolphin flipper at bottom left obeys the same principles in a different fluid medium; it is an example of a hydrofoil. Streamlines on an airfoil visualised with a smoke wind tunnel An airfoil ( American English ) or aerofoil ( British English ) is a streamlined body that is capable of generating significantly more lift than drag .

A hydrofoil is a lifting surface, or foil, that operates in water.They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils.
A foil generates lift primarily because of its shape and angle of attack. When oriented at a suitable angle, the foil deflects the oncoming fluid, resulting in a force on the foil in the direction opposite to the deflection. This force can be resolved into two components: lift and drag. This "turning" of the fluid in the vicinity of the foil ...
High-tech architecture, also known as structural expressionism, is a type of late modernist architecture that emerged in the 1970s, incorporating elements of high tech industry and technology into building design. High-tech architecture grew from the modernist style, utilizing new advances in technology and building materials. It emphasizes ...
A foil bearing, also known as a foil-air bearing, is a type of air bearing. A shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air) pushes the foil away from the shaft so that no contact occurs. The shaft and foil are separated by the air's high pressure ...
Architectural design competition - a specialist competition inviting architects to submit design proposals for a project. Architectural technology or building technology - is the application of technology to the design of buildings. It is a component of architecture and building engineering and is sometimes viewed as a distinct discipline or ...
ARCADIA, a model-based engineering method for systems, hardware and software architectural design. ARCADIA ( Arc hitecture A nalysis & D esign I ntegrated A pproach) is a system and software architecture engineering method based on architecture-centric and model-driven engineering activities.
