Approach, solution

  • Complete, independent development of concept up to qualified prototypes for series production
  • Market study and selection of a suitable audio test procedure
  • Sturdy design
  • Temperature requirements -40°C..+70°C
  • Extremely water-tight
  • High acoustic requirements
    • High ambient sound level, up to 94dbA
    • Echo cancellation
    • Suppression of acoustic feedback (Larssen Effect)

Results & added value

  • Our customer is extremely well satisfied. The device is currently being installed without modifications in another cargo plane.

 

Project Reference

Client company name, country of project

  • One of the leading aircraft manufacturer, Germany

Altran Business Line, domain of intervation, project duration

  • Altran Solution Center (ASC); Hamburg Development Center
  • Duration of project up to run-capable prototypes: 3.5 months
  • Total duration: 11 months

Context & objectives

  • Development of a 4-LED light source

Functional & technical environment (tools as required)

  • The colour and the brightness of the LEDs (Light Emitting Diodes) are, due to active control, absolutely stable over the life cycle of the device and independent of external influences (e.g. temperature).
  • Thermal management

Approach, solution

  • Complete, independent development of concept up to qualified prototypes for mass production
  • HW (hardware), SW (software), design and development of mechanical components
  • Thermal simulation

Results & added value

  • Extremely fast design cycle
  • First time right

Client company name, country of project

  • One of the leading aircraft manufacturer, Germany

Altran Business Line, domain of intervation, project duration

  • Altran Solution Center (ASC) ; Hamburg Development Center
  • Total duration: 12 months

Context & objectives

  • Development of a PCB for driving reading lamps, Fasten-Seat Belt & No Smoking Sign, pushbuttons and audio transmission
  • Automatic adaptation of currents to the LED (Light Emitting Diode) activated in the reading lamp (discontinuation problems)
  • Continuously variable dimming of the reading lamps

Functional & technical environment (tools as required)

  • Application of new, innovative technologies (weight and cost reduction)

Approach, solution

  • Complete, independent development of concept up to qualified prototypes for mass production
  • HW (hardware) and FPGA (Field Programmable Gate Arrays) development

Results & added value

  • First installed in 2005
  • Cost-optimised variants for single-aisle, long-range and another cargo plane is currently under development
