Stronger Wings - Innovation Nation

The video discusses the use of carbon nanotubes in aerospace engineering, particularly in airplane wings. These nanotubes can enhance the strength of composite materials and enable self-healing by detecting and repairing cracks. Unlike aluminum, composites with nanotubes can detect internal damage and repair it mid-flight, offering a significant advantage in aircraft safety and maintenance.

Describe the process of how a crack in a wing can be repaired using carbon nanotubes.

What does the term 'self-healing airliner' refer to in the context of this technology?
