Shark Skin Inspired Coating Reduces Aircraft Emissions and Fuel Use

Shark Skin Technology for Aircraft Efficiency

• 🦈 An Australian startup, Microtow, has developed an adhesive film inspired by shark skin to reduce drag on aircraft.
• 💡 The technology uses a 'riblet film' that mimics the natural drag-reducing properties of shark skin, aligning with airflow to improve efficiency.
• ✈️ This innovation aims to make flights more efficient, requiring less jet fuel and thereby reducing global aviation emissions.

How the Technology Works

• 🔬 The riblet film functions similarly to the microscopic structures on a shark's skin, which create micro-turbulences that reduce overall drag.
• 🌊 For sharks, this reduces drag in water; for aircraft, it reduces drag from air flow, leading to improved performance.
• 🛠️ Advances in manufacturing and material science have made it possible to produce this film at scale and ensure its durability on aircraft exteriors.

Impact and Trials

• 📊 Aviation contributes 2.5% of global energy-related CO2 emissions, making fuel efficiency improvements crucial.
• 📈 Microtow claims its film can achieve efficiency gains of up to 4%, leading to significant reductions in jet fuel consumption.
• ✅ The startup has conducted a full-scale flight trial with the US Air Force and is collaborating with Delta Airlines on product design for their Boeing 767.
• 🌍 Microtow has also secured its first European customer and plans to explore applications for marine crafts in the future.
