With the Asian Business Aviation Conference & Exhibition (ABACE) on the horizon this month, show organizers are anticipating approximately 7,000 attendees, nearly double last year’s mark, based on the success of 2012’s re-launch. According to an NBAA spokesman, 84 percent of last year’s exhibitors will be returning for a second stint at the Shanghai Hawker Pacific Business Aviation Service Centre, and the number of exhibitors overall has increased from 156 last year to more than 175 this year.

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.
