ESDs (Energy saving devices) AFT of the propeller

Short description
Aft energy-saving devices are installed behind the propeller to recover energy from the propeller wake. They improve thrust efficiency without changing the main propulsion system.
What it includes
- Post-swirl fins or ducts behind the propeller
- Wake flow recovery and stabilization
- Design adapted to propeller and hull geometry
Why it matters
Recovering wake energy reduces fuel consumption at the same speed.
