Rolls Royce Olympus IV

This Olympus was looking good as it hit all the marks and passed all the tests on its first try at the test cell in Fort St. John, BC. Notice how much more slowly an industrial engine is powered up compared to an airliner engine... one of the reasons they last more than ten times longer between overhauls... The smoke you see is common on the first runup after rebuild; it’s sealants curing and assembly lube flashing off.
