IHI副事業部長による日英共同エンジン実証の内容
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.
“We are now sending IHI engineers to Rolls-Royce and they are sending engineers to us in Japan,” said Sato.

The propulsion design will be highly integrated in the air platform, optimising overall performance, range and payload capability.
Through an innovative approach to Thermal Management System integration, utilising the gas-turbine as a heat ‘sink’ to recycle
thermal energy around the platform, removing the need for overboard venting and improves overall system efficiency. Increased
electrical power generation capability coupled with an intelligent power management system will meet the growing demand for
electrical power. This integrated power approach reduces the number of energy exchanges, maximising the potential of the
gas-turbine as the primary power source.

GCAPはテンペストだから当然だなｗ
