lentokypärä

Lentokypärä, meaning "flight helmet" in Finnish, refers to protective headgear designed for individuals involved in aviation. These helmets are crucial for protecting pilots and aircrew from potential head injuries during flight operations. The design of a lentokypärä varies depending on its intended use, ranging from general aviation helmets to specialized versions for military fighter pilots, helicopter crews, and even astronauts.

Key features of a lentokypärä typically include a hard outer shell made from materials like fiberglass, carbon fiber, or advanced composites to provide impact resistance. Inside, a liner of shock-absorbing foam, such as expanded polystyrene (EPS) or EPP, cushions the head against blows. Many flight helmets also incorporate a chin strap and sometimes a nape strap for a secure fit, preventing the helmet from shifting during high G-forces or abrupt movements.

Beyond protection, modern lentokypärät often integrate communication systems, including boom microphones and earpieces, allowing for clear communication with air traffic control or other crew members. Some military variants also feature visors or sun shades for glare reduction, and provisions for mounting night vision devices or other specialized equipment. The weight and comfort of a lentokypärä are important considerations for long flights, and designs are continuously refined to balance protection with ergonomics.
