By Marina Lopes WASHINGTON (Reuters) – Engine maker Pratt & Whitney will partner with International Business Machines Corp to compile and analyze data from about 4,000 commercial aircraft engines in order to be able to predict trouble before problems arise, the company announced on Thursday. The announcement comes as more aircraft engine suppliers tune in to data analytics to increase safety and reduce costs. Pratt & Whitney, a subsidiary of United Technologies Corp, said in a statement it has hired IBM to analyze the half terabyte of data that engines generate on every flight to detect and predict engine trouble. “Rather than reacting to some sort of an engine event, we are leveraging data from various sources for maintenance, for planning engine diagnostic systems and building predictive models,” Jerry Kurtz, vice president of strategy and analytics at IBM, said.
