Abstract
The invention relates to a rotor blade for a wind turbine. The rotor blade comprises a shell and a spar forming a longitudinally extending hollow structure within the shell and comprising: a leading web, a trailing web, and one or more additional webs. Each additional web defines an intermediate portion between a hub end and a tip end. The intermediate portion of each additional web is spaced apart from the leading and trailing webs and at least one of the tip and the hub ends is connected to or integral with the leading or the trailing web. The invention further relates to a wind turbine comprising the rotor blade, and a method for manufacturing the rotor blade.
