The safety monitoring and tracking of aircraft is becoming more and more important. Under
aerodynamic loading, the aircraft wing will produce large bending and torsional deformation …

Flight testing is both vital for collecting data for aeronautic research and at the same time
fascinating for its contributors. Taking a glider as a versatile test bed example, this paper …

Aircraft wings are subject to deflection. Designers must therefore take into account in-flight
wing bending and torsion, so that structural loads are well taken care of and that the wing …

In aeronautical research experimental data sets of high quality are essential to verify and
improve simulation algorithms. For this reason the experimental techniques need to be …

AJOINT aeroelastic research project called WIONA (wing with oscillating nacelle) was
performed by the ONERA French aerospace lab and the DLR, German Aerospace Center …

For the investigation of the effectiveness of special high lift devices like mini trailing edge
devices (Mini–TEDs) and sub-boundary vortex generators (SBVG) it is necessary to obtain …

During certification of a new aircraft the loads and thus the deformations occurring in free
flight have to be measured to prove the safety of the structure. Strain gauges and …

The measurement of the phase center of the airborne array antenna can directly affect the
accuracy of the Earth observation system. However, the relationship between the relative …

A dedicated multi camera system was developed by DLR with the objective of flap gap
observation within the EC funded project AWIATOR of the 5th frame work programme of the …

For the design of a helicopter rotor blade, it is crucial to predict the dynamic behavior and
occurring forces and moments. For the validation of prediction tools, reliable flight test data is …
