Originally developed for the military Lynx helicopter, these systems cover the monitoring and time-referenced signal recording and analysis of more than 10 signals such as:
• rotary speed of the main rotor,
• speed of high- and low pressure turbines,
• drive torque,
• angle of bank,
• load on the sponsons,
• exceedance of minimum height for radar measurement,
• exact determination of the rotor start / stop cycles
• estimation of the life time of the turbines,
• acoustic and optical warning signals for the pilot can also be activated when the maximum rotation speed of the main turbine is reached, or in case the radar height measurement falls below a minimum level and for excessive stress loads on the landing gear.
The AIDA data acquisition systems feature proven higher flight safety, extending the inspection intervals for all mechanical parts of the air craft and considerably reducing the aircraft service costs.
Typical applications of the AIDA data acquisition systems include the determination of start and landing weights, measurement of actual flight hours, load at landing, determination and analysis of manoeuvres and incidents.
The following are some of the technical specifications of AIDA recorders:
• acoustic warning signal for main rotor overspeed
• acoustic warning signal for radar altimeter low heights
• exact measurement of rotor start / stop cycles
• estimation of turbine life time consumption
• drives a dedicated lamp in the CWP
• built-in self monitoring features
• time history recording of more than 10 signals
• internal storage lasts for more than 100 flight hours
• fast data read out via SRAM cards
The AIDA recorders are certified for aviation systems according to the MIL-STD-810E, electromagnetic compatibility according to MIL-STD-416D and vehicle power supply according to MIL-STD-704E.
