Rescue parachute: lightweight Annular EVO Our development progress, especially in material development, resulted in essential advantages regarding weight reduction and strength. In our Annular EVO series we use a new, extremely light and highly tensile fabric and lines, thus achieve a weight reduction of 30% compared to Annular Classic.
Early parachute designs predominantly-used silk in parachute production due to its light weight and strength, but silk has largely been replaced by modern materials. Fabric and geometrical permeability are carefully considered during the design phases of the parachute.
Ram-air parachutes are full of air. Ram-air parachutes are a type of parafoil parachute or canopy, used to lower one’s descent speed so that safe arrival on the ground can be achieved, or to glide in the air, although those used for gliding purposes are typically called a ‘paraglider’.
The Rogallo wing is most often seen in toy kites, but has been used to construct spacecraft parachutes, sport parachutes, ultralight powered aircraft like the trike and hang gliders. Rogallo had more than one patent concerning his finding; the due-diligence expansion of his invention involved cylindrical formats, multiple lobes, various stiffenings, various nose angles, etc.
