Abstract

In an existing aircraft landing system, the generator is used for driving the electrical systems, whereas brushless DC generator (BLDC) is used as an auxiliary generator in case of failure in the main generator. In order to improve the performance of a brushless DC generator various parameters such as voltage, current, temperature, torque, lube oil flow, lube oil temperature, lube oil pressure are measured. Previously these parameters were measured by Data Acquisition System (DAS) with minimum sampling rate. The output voltage was fluctuating and was not maintained at 28V. In the proposed system the parameters to be measured are sensed using various sensors and the same is acquired into the system through Data Acquisition System with increased sampling rate and LabVIEW software. At various speeds, the operation of the system under no load and loaded conditions is checked and if there is any deviation from the set values, corresponding control action is taken. The output voltage is maintained constant at 28 V, which was difficult in the existing system.
