Aircraft flight testing is an extended branch of
aerospace science and its development is
closely related to the increasing requirements of
the traffic safety.
Contemporary the prototype flight testing
of a small aircraft does not include a flight
measurement with a data recording because the
cost of these measurements is not acceptable for
companies building these kinds of aircraft. The
result of this flight measurement is a data file
containing very useful aircraft information for a
designer. Knowledge of the flight behaviour and
flight loads of a sport aircraft, a glider or an
ultralight has got a positive influence on sport
flying and soaring safety.
Looking on all the special requirements
for small aircraft flight testing the development
of a new portable data acquisition system (DAS
12) was started at the Institute of Aerospace
Engineering of Brno University of Technology
with the collaboration with Mesit ltd. The
system should fully satisfy all the requirements.
DAS 12 is digital twelve-channel mobile
data acquisition system dedicated for strain
gauges measurements, pressure measurements,
temperature and other analogue variable
measurement.
Data acquisition system is created
together with a sensor set. The sensors capture
the movement of the aircraft from rolling until
the landing.
