Don't know where this $17 billion number came from. In FY 2014, Yahoo Finance shows
Income Before Tax 8,887,000
Income Tax Expense 2,264,000

Looks like about 25.5%.
I guess it's possible they doubled their profit between 2014 and 2015, but I'd be shocked.
Revenue at United Technologies, which also produces Pratt & Whitney jet engines and Black Hawk helicopters, rose 1.9 percent to $16.76 billion, it said on Wednesday. That was about $330 million short of analysts’ expectations.
