Abstract

The scope of the work is to develop a cooling system which uses wing-bay air to cool the ElectroMechanical Actuators (EMA). The wing-bay is enclosed. The system will operate between 20% and 100% of atmospheric pressure. Using high speed fans as a means of cooling the EMAs it is important to understand the characteristics of the fan. The study also closely observed the results obtained experimentally with that of the fan scaling analysis. The fan laws can be derived from dimensionless analysis of volumetric flow rate, static pressure, and power equations. Considering the current experimental data, the fan scaling laws can be used to verify the proper nature of the fan curves when using a certain measurement at the baseline. In this study, the results have been verified for various rotational speeds and ambient pressure conditions. Consequently, there are two fans that have been tested within the loop. The first fan is a 2 bladed fan whereas the other fan has a 12 bladed propeller. The fan performance curves will determine the cooling capacities of each and provide a means to compare geometrically different fans.
