Abstract
A flying vehicle propulsion system comprises a propulsor, a drive system, a heat exchanger, and a housing in which the heat exchanger is provided. The propulsor produces a propulsor fluid flow. In a first operation configuration of the propulsion system, at least part of the propulsor fluid flow is incident on the exchanger. A propulsor fluid flow inlet port of the housing fluidly communicates with a chamber of the housing on an inlet side of the exchanger. The inlet port receives the propulsor fluid flow for ingestion into the chamber and exchanger and comprises a valve to close the port when the valve is closed and open the port when the valve is open. The valve is biased such that at least one of: the valve opens passively under a propulsor fluid flow rate influence above a pre-defined threshold impinging on the valve; and the valve closes passively under a biasing influence.
