A navel postswirl propulsor designed for a small vehicle is addressed The major benefit of this design is the simplicity of the machinery arrangement. The challenge of this design is the low value of Reynolds number which may cause flow separation on the propulsor blade surfaces. Open-water and self-propulsion experimental results show that the performance predictions agree well with the measurements.
