United Technologies' Pratt and Whitney military engines unit is working on the final two years of design work on the Pentagon's Adaptive Engine Technology Development (AETD) programme, according to the company official who oversees the company's sixth-generation engine work.
AETD "goes through 2016, so there is still a lot of work to be done," Jimmy Kenyon, Pratt and Whitney's next-generation fighter engine general manager, told IHS Jane's on 20 May. "This year is going to be a lot of work on design."
By 2016, the company will be ready for "a couple of big tests". Kenyon said those technology demonstrators are likely to take place at a US Air Force (USAF) facility.
