Intake system for an atmosphere breathing electric thruster for a spacecraft

An intake system for an atmosphere-breathing electric thruster, comprising:

• an inlet for an inflow of air;
• an outlet for coupling to the atmosphere-breathing electric thruster for fueling the inflow of air to the atmosphere-breathing electric thruster;
• a collector arranged between the inlet and the outlet, said collector comprising at least a movable section and a static section, each of the movable section and the static section having circumferential walls with radial walls extending therebetween to define channels in the movable section and the static section for allowing the inflow of air to pass towards the outlet, wherein the movable section and the static section share a common central axis over an axial direction in which the movable section and the static section extend, wherein the movable section is rotatable about the common central axis and the static section is non-rotatable about the common central axis, and the channels of the movable section and the static section cooperate to define paths for the inflow of air to follow, each path having an inlet area;
• wherein the each inlet is adjustable by rotation of said movable section relative to said static section.
