Abstract
This thesis takes the much discussed and comparatively little used lattice theory and applies it to the design of fans. The application is made through the use of charts coming out of the theory. It is felt that by the use of the charts that the design of confined fans, that is those where end effects on the blades need not be considered, will be made considerably simpler and easier.
The use of the lattice theory in the design of fairly complicated vane systems is discussed, and an approximate method of analysis is given. This subject requires more study in the near future.
As yet, at the time of writing, the method has not been checked by experiment, and as a result not much may be said concerning the accuracy of the results as actually applied to design. However, the use of the lattice theory gives designs that appear to be reasonable, and it is hoped that the method will prove to be fairly accurate in actual practice. At present a fan and vane installation as shown in Fig. XIII and Fix. XV is being constructed, and it is hoped that it will be possible to present some experimental data on the design in the near future.

Axial Fans Selection Software
Introduction
Fans Selector is a centrifugal and axial fans selection program, developed by Altec srl, that enables a manufacturer to select, calculate performance and printout a technical report of its fans production range.
By using Fan Selector software, the manufacturer can quickly and easily determine the most suitable axial and centrifugal fans for its demands.
After entering the basic conditions, the ideal product for every requirement can be found with just a few clicks. Furthermore, all necessary product information such as technical data, including noise calculations, total sound power spectrum, natural and operating frequencies, performance curve plotting and so on can be obtained.
The software is highly customizable, both from input data possibilities and from required outputs perspective, based on the needs of the single manufacturer.
The following is an example of the main window of the software, which shows the range of fans matching the given input conditions and the data and performance curves of a specific fan chosen inside the proposed list.
Input data
While some essential input data must mandatorily be specified, for some others an 'AUTO' option is available: in this case, if chosen by the user, the selection algorithm will consider all the fans matching all possible values for the input data. Finally, some parameters are already pre-filled in the input mask with default values, that can be freely modified by the manufacturer if needed.
This input criteria has a twofold purpose:
- It allows a very quick selection, by specifying only the mandatory input data and by leaving the AUTO option and the default values set in the remaining fields of the input mask
- It enables also a very detailed and specific selection, giving the user the possibility to specify a wide range of information for the fans to be selected
The fans range selection
In a very quick and straightforward way, the software propose a set of fans that match the input criteria. For each equipment, the main performance data are displayed.
The following picture show an example of the selected fans range which match the input data referred in the previous section.

Fans selection parameters
In the selection phase, it is possible to specify some criteria to be applied to the calculation. In the example, two parameters are available:
- Selection by max efficiency
- Selection by minimal sound power level
The results
By selecting one of the fan showed in the selection list, the detailed performance data and performance curves are showed in the 'Results' section of the main window of the program. The working point of the fan is also showed.
The printout
The user can print a technical report including all the required data about the selected fan and save it in PDF format.
The following is an example of the printout generated by the software and related to the example used in the previous sections.
Further improvements and developments
Altec is willing to satisfy all manufacturer's requests and needs: further improvements to the software are possible, if required by the customer, as well as the development of new modules in order to add new functionalities to the existing ones.

The software allows the user to specify a very detailed list of input data and parameters. The list of input can be tailored based on the manufacturer requests.
While some essential input data must mandatorily be specified, for some others an 'AUTO' option is available: in this case, if chosen by the user, the selection algorithm will consider all the fans matching all possible values for the input data.
