Data Aquisition

dataaquisition2KDL develops and produces a range of data recorders that utilise Flash Memory cards that conform to the PC card PCMCIA ATA standard. The current range of data recorders are primarily for use in aircraft, encompassing fixed-wing, rotary-wing, military and civil. The data recorders fitted to these aircraft fulfil three key roles:

1) Maintenance Data Recorder

Data derived from the aircraft engine, transmission and airframe are recorded onto the PC card. This data is analysed by ground-station software to determine the condition of these safety critical components. The analysis results in a 'stress history' of the aircraft and identifies the first signs of component failure, allowing for the scheduling of maintenance when the aircraft requires it. The benefits of this process are to provide early warning of component failure and provide cost savings in aircraft maintenance schedules.


2) Quick Access Recorder

Data derived from aircraft control signals are recorded onto the PC card (The same data that is recorded onto the crash recorder). This data is analysed by ground-station software to determine the flight profile and the proficiency with which the aircraft was controlled during the flight. The analysis can be used to produce improved flying techniques and to identify training needs of pilots. The benefits of this process are to improved flying techniques, minimise stress on the aircraft, improve fuel consumption, improve passenger comfort and identify dangerous practices.

3) Mission Data Recorder

Data derived from other airborne systems during a mission are recorded onto the PC card. This data is analysed by ground-station software to determine the success of the mission and to plan future missions The benefits of this process are to reduce the pilot workload and to provide data about the environment through which the aircraft flew.

These data recorders are designed for aircraft environments and are therefore ruggedised against temperature variation, vibration, humidity and EMI (Electro-magnetic interference). They are housed in machined enclosures measuring approximately 120mm x 120mm x 40mm,with a hinged cover to protect the card slot. The memory cards contain non-volatile memory that will currently hold up to 1Gbyte of data, packaged in an enclosure approximately 85mm x 55mm x 5mm. The data on the cards can be accessed by any PC fitted with a PCMCIA memory card reader.
