RRがIHIと共同実証しているのはこの「統合熱・電力管理システム」を備えたadvanced power and propulsion system.

IHI佐藤氏の発言からもそれがうかがえる。
Sato said that the collaborative programme – named the ‘joint demonstrator engine' project – aims to prove capabilities
including power generation and thermal energy management in an engine that is sufficiently compact for the GCAP fighter.
He said the two companies aim to develop an engine prototype by the late 2020s to enable integration into the initial batches
of GCAP fighters to be produced from the mid-2030s. Initial tests of the engine will take place in the UK, he said.
