Helicopter H/S envelope Outlines - The SFACT research activities - Origin of this research program - Description of the study
SFACT Research activities - Evolution of the regulation - Various domains Occupant survivability, Human factors, External hazards, Environment and Innovation - International cooperation JAA RC, CSRTG, …
Origin of the project - The Height / Speed envelope SAFE LANDING PROHIBITED AREA height O speed
Origin of the project(II) The regulation - Compatibility between T/O and Landing trajectories // Regulation SAFE LANDING PROHIBITED AREA height O speed
Origin of the project(IIbis) The operational context - Compatibility between T/O and Landing trajectories // Regulation SAFE LANDING PROHIBITED AREA height O speed
Origin of the project (III) - The Height / Speed envelope - Compatibility between T/O and Landing trajectories // Regulation - Coherence between JAR 27/29 and JAR OPS3 Safe emergency landing
Description of the study - Theoretical part : 1 year Analysis of accident and flight test data > Determination of the consistent parameters Horizontal/Vertical speed, Rotor lift Pitch, Roll, Yaw attitude > Determination of the survivable envelope Development of a structure model JAR 27/29 helicopter Survivable vertical speeds
Description of the study (II) - Experimental part : 2 years Validation of the model Simulation of the h/s envelope for > landing skids / wheels > influence of the configuration
Final objective Current envelope No injury only material damage No serious injury Material damage Forbiden area : Serious injuries Loss of the a/c h Survivable Height / Speed Envelope ( low part especially) 0 s
