Control method for controlling a buoyancy system for an aircraft, a buoyancy system, and an aircraft
Patent number: 10000281Abstract: The present invention relates to a control method for inflating at least one float of a buoyancy system. During a mode (MOD1) of automatic inflation in flight, calculation means determine whether a predetermined ditching condition is true during a step (STP1) of predicting a forthcoming impact. During a step (STP2) of characterizing said impact, at least one predicted component of a ditching speed is determined. During an automatic inflation step (STP3), each float is automatically inflated in flight when at least said ditching condition is true and when each determined predicted component is less than a corresponding speed threshold.Type: GrantFiled: January 27, 2017Date of Patent: June 19, 2018Assignee: AIRBUS HELICOPTERSInventors: Louis Delorme, Didier Bertin -
