Rolls-Royce has completed testing of the latest build of a research two-shaft engine core, known as “Core 3/2d,” as part of the E3E (efficiency, environment, economy) program. The core evaluation campaign ends without a previously planned endurance test, however. E3E technology forms the basis of Rolls-Royce’s Advance2 future two-shaft engine program, which targets entry into service in 2018.
