Stabilizer for rotor blade with longitudinally running gap involves bracing of double blade root and additional surface on upper blade leg running from root to hole formation

摘要

The rotor blade with a longitudinally running gap has a stabilizer. A surface (3) on the upper blade leg (6) runs from the root (4) to the hole formation (5), widening the leg, so that it covers over the longitudinally running gap and the lower leg.
