Abstract
A coolant system is arranged to be driven by a prime mover of an aircraft. The coolant system comprises a fluid circuit with a fluid therein, the fluid for cooling an electricity generator located in the fluid circuit. The fluid circuit comprises: a cooling path passing via at least one cooled component of the generator; a first fluid flow source configured to deliver a first fluid flow to the cooling path; a second fluid flow source configured to generate a second fluid flow; and a valve arrangement configured to selectively direct at least a proportion of the second fluid flow away from the cooling path in dependence on a measured operational parameter of the generator. An aircraft propulsion system and an aircraft can also include the coolant system.
