The effort, which has to date been running for five years, is geared towards managing “unprecedented levels of electrical power demand and thermal load … within the context of a stealthy aircraft.” The goal is to provide both the thrust to propel the aircraft and the electrical power required for all the systems, while managing the resulting thermal loads.

According to Rolls-Royce, the Tempest effort builds on earlier work to address future aircraft power demands. In 2014 it designed an electrical starter-generator that was fully embedded in the core of a gas turbine engine, now known as the Embedded Electrical Starter Generator (E2SG) demonstrator programme.
