"This is an even bigger achievement for FRCE, using our printers to make polymer AM repair parts on H-53E main rotor
blades that will enter the supply system and be used by the fleet."
Second, the peak values of the controls (e.g., main rotor
collective and longitudinal cyclic blade pitch angles) are the smallest for the 1st closed-loop system.
Reduced demand for power to the main rotor
during cruising means one engine can be turned off, an operation aided by a 300V stop-start system that hints at the emergence of electrified solutions in rotorcraft.
A report by the Air Accidents Investigation Branch (AAIB) found that the gearbox failure caused the main rotor
on the AS332-L2 model to break away and its "tail boom" got severed from the fuselage.
PALV's main rotor
moves slower than a helicopter's rotor, making it quieter and letting it take off and land at lower speeds.
All three of the Eurocopter EC135 aircraft were brought in for checks after cracks appeared in the main rotor
hubshaft flange on models elsewhere in Europe.
It follows the discovery of a fault in an air ambulance in Scotland last month when a crack was discovered on the main rotor
A safety warning was issued by the European Aviation Safety Agency (EASA) after a crack was discovered on the main rotor
hub of a Eurocopter EC135 aircraft in Scotland.
A crack was discovered on the main rotor
hub of one Eurocopter EC135 helicopter, prompting a safety warning by the European Aviation Safety Agency (Easa).
The equipment rolled toward a taxiing helicopter a short distance away and inevitably headed under the tip-path of the rotating main rotor
The corrosion was so bad that they had to remove the assembly, which fits over the main rotor
shaft and rests on the top of the main gear box.
Among the S-76D helicopter's features are all-composite, flaw-tolerant main rotor
blades; an advanced Thales avionics system and autopilot; dual rotor speed for quiet mode operation with active vibration control; Pratt & Whitney 210S engines; a quiet mode; and an optional Rotor Ice Protection System (RIPS) for all-weather capability.
