Maximum efficiency is of the utmost importance to us when developing our rotor blades.
Our blades are aerodynamically streamlined in all their dimensions and are designed to yield the optimal power output at high average wind speeds. Their relatively low rotation speeds and a state-of-the-art production technique ensure a particularly long service life. BARD blades rotate at speeds that are roughly 20 percent lower than those of conventional rotors. This minimises wear and tear at the wing tips, thus considerably reducing maintenance expenses.
We rely on glass-fibre reinforced plastic based on epoxy resin. This material has proven effective in the construction of rotor blades for well over a quarter of a century. All three-dimensional components and reinforcements have a core made of synthetic foam.
