It works :-)
flight test with rotating camera successfully completed
Beginning of January the rotating camera for measuring the deformation of a propeller blade during flight was flying the first time. The flight tests were performed by Evektor, Avia Propeller and DLR at the EVEKTOR plant in Kunovice (CZ).
The painting of the blade and the balancing of the complete propeller with the mounted rotating camera was performed at AVIA Propellers in Prague (CZ). To paint the stochastic pattern for IPCT on the blade, a painting mask was created and sticked on the blade. After painting, the whole system (Propeller with painted blade and mounted rotating camera) was balanced and transported to EVEKTOR. There it was fitted to the Evektor VUT-100 COBRA experimental airplane.
During four flights in total the new developed rotating camera was recording one propellerblade phase locked and also once with a moving phase shift to measure the complete revolution.
In total around 200GB of image data was recorded including several on-ground and in-flight propeller loadings. First data evaluation showed, that the recordings can be processed by IPCT to get information about the in-flight shape and behaviour of the propellerblade.
Thanks to the teams of EVEKTOR, AVIA-Propeller and DLR, as well as the polish company HARDsoft the flight test of the rotating camera was a great success. For the documentation of the test we also thank fotoworx photo&film.
