Abstract
A propulsion system for an aerial vehicle with a suppressed radar observability comprises one or more rotors with rotor blades; a fuselage, a tubular channel structure, and a shielding structure. The fuselage provides a support for the one or more rotors and at least one integrated engine to drive the one or more rotors, wherein the rotor blades protrude radially outwards from the fuselage. The tubular channel structure circumferentially extends around the fuselage and covers the protruding rotor blades, wherein the tubular channel structure includes an inlet and an outlet between which the rotor blades are arranged to drive a propulsion airflow. The shielding structure is formed at the inlet and/or at the outlet for radar signals to suppress radar detection of the rotor blades.

A propulsion system for an aerial vehicle with a suppressed radar observability, the system comprising:
- one or more rotors with rotor blades;
- a fuselage with a support for the one or more rotors and at least one integrated engine to drive the one or more rotors, wherein the rotor blades protrude radially outwards from the fuselage;
- a tubular channel structure circumferentially extending around the fuselage and covering the protruding rotor blades, wherein the tubular channel structure includes an inlet and an outlet between which the rotor blades are arranged to drive a propulsion airflow;
- and
- a shielding structure at the inlet and/or at the outlet for radar signals to suppress radar detection of the rotor blades.
A method of manufacturing a propulsion system of an aerial vehicle with a suppressed radar observability, the method comprising:
- providing a fuselage with one or more rotors and at least one integrated engine to drive the one or more rotors, wherein rotor blades of the one or more rotors protrude radially outwards from the fuselage;
- forming a tubular channel structure circumferentially extending around the fuselage and covering the protruding rotor blades, wherein the tubular channel structure includes an inlet and an outlet between which the rotor blades are arranged to drive a propulsion air flow;
- and
- forming a shielding structure at the inlet and/or at the outlet for radar signals to suppress radar detection of the rotor blades.
