A theoretical derivation of the Cordier diagram for ...

The design of high-efficiency fans is often based on the experience of the designer. In order to determine its main dimensions, fan designers use the Cordier diagram. For a given operating point (i.e. flowrate and pressure, and a rotating speed), the optimum diameter of high-efficiency fans can be found in the Cordier diagram. The Cordier diagram is an empirical diagram based on measurements.

The second part uses an adaptation of a construction of Graeme Segal to 'rigidify' a coherent diagram; tha its to say, given a homotopy coherent A-indexed diagram X, we construct a commutative diagram X indexed by A and a coherent map X-+X such that for each object A o Af, the corresponding is a homotopy equivalence.
