Surface pressure measurements at two tips of a model helicopter rotor in hover [PDF]

Surface pressures were measured near the tip of a hovering single-bladed model helicopter rotor with two tip shapes. The rotor had a constant-chord, untwisted blade with a square, flat tip which could be modified to a body-of-revolution tip.

Aramid Nanofiber Aerogels: Versatile High Complexity Components for Multifunctional Composites

Advanced Materials, EarlyView.
Different forms of aramid nanofibers (ANFs) and especially aerogels from them, offer a sustainable route to high‐performance biomimetic nanocomposites. Due to the cartilage‐like architecture, ANF‐based materials enable breakthroughs in energy, electromagnetic, biomedical, and water purification technologies.
