A method for manufacturing a loop blade for a propeller, comprising:

• selecting a pre-curved workpiece based on target loop blade specifications;
• configuring a cutting machine based on the target loop blade specifications;
• and performing a single cutting operation on the pre-curved workpiece to create the loop blade, wherein the pre-curved workpiece is selected from the group consisting of a closed pipe, an open pipe, an oval pipe, and a helical wrapper, wherein the target loop blade specifications include at least one of a diameter, wall thickness, pitch angle, and width, wherein configuring the cutting machine includes setting a cutting blade angle to match a specified loop blade pitch angle, and wherein the loop blade created is selected from the group consisting of a closed loop blade, a semi-loop blade, and a partial loop blade.

A method for manufacturing a loop blade for a propeller, comprising:

• selecting a pre-cut flat workpiece based on target loop blade specifications;
• configuring a curving machine based on the target loop blade specifications;
• and performing a single curving operation on the pre-cut flat workpiece to create the loop blade, wherein the pre-cut flat workpiece is selected from the group consisting of a flat sheet and a bar, wherein the target loop blade specifications include at least one of material, length, width, thickness, and pitch angle, wherein configuring the curving machine includes setting a curving fixture cylinder diameter and angle corresponding to a specified loop blade pitch angle, and wherein the loop blade created may include straight wings.
