On April 9, the NTSB held a public meeting to discuss the crash of a LifeNet helicopter in Mosby, Mo., on Aug. 26, 2011. The Eurocopter AS350B2 ran out of fuel, according to the NTSB, and the pilot failed “to successfully enter an autorotation when the engine lost power due to fuel exhaustion.” What the pilot did not do, the Board explained, is move the cyclic control aft when the engine failed.

Air blown through small holes in the blade makes dynamic stall less severe in demanding maneuvers, according to researchers at DLR.

Researchers at the German Aerospace Center (DLR) in Göttingen may have discovered a way to make helicopters more maneuverable, by reducing the dynamic load on the rotor head control rods.

During rapid forward flight or maneuvering, airflow stalls on the main rotor blade as it retreats (moves backwards), giving rise to a “dynamic stall” and subjecting the rotor head control rods to formidable dynamic loads.

Eurocopter Japan has delivered to Japan’s Fire and Disaster Management Agency a Eurocopter AS365N3 Dauphin medium-twin helicopter retrofitted with a high-speed, real-time satellite transmission system. The helicopter’s satellite communication system enables direct transmission to relay satellites, without interruption by the helicopter’s moving rotor blades. Mitsubishi Electric developed the system, which solves these interference issues when ground-based networks are unavailable.
