In this study, a flight data recorder to be used on
helicopters was designed, produced and tested to show compliance to
international aviation standards. In design studies, dynamic, static and
thermal analyses of flight data recorder were did in the Ansys Finite Element
Program numerically. In the experimental
study, the tests of performed analyses in computers were carried out in
laboratory. In the dynamic test, an apparatus weighing 227 kg, with a steel pin
on the lower surface, was dropped onto the memory module from a height of 3 m. Permanent
deformation of the part surface was measured as 2.12mm in laboratory, similarly
the same deformation was calculated as 1.99mm in computer analysis. In the
compression test, the flight data recorder was compressed with a load that is
4500 kg by a hydrostatic press. In both numerical and experimental studies of
compression test, the deformation of the flight data recorder is in elastic
range of the material since there is no significant deformation in the flight
data recorder. In the thermal conductivity test, 1100°C
temperature applied to the upper wall of the flight data recorder for 1800sec.
and thermal distribution of interior of the model was investigated. As a result
of the numerically analysis and experimental study, it was observed that the
card resist until 150°C
temperature in the memory module was exposed to 90०C temperature. It was seen
that, the results of mechanical and thermal tests which have been performed on
designed Flight Data Recorder are compliant with international aviation
standards.
