A propulsion unit having reduced noise employs a rotor (16a, 16b) having a plurality of variable pitch blades (22). A tensioning joint mechanism (28) is carried within each blade (22) and a tension element (20) is engaged by the tension joint mechanism (28). The tension element (20) is configured to maintain tension between the blades (22) in the rotor (16a, 16b) and the tensioning joint mechanism (28) adapted to allow variation of pitch of the blades (22) without altering tension in the tension element (20).
