The use of photogrammetry for special flight tests

Carrying out flight tests of de-icing systems of aircraft in real or artificial conditions, apart from the measurement of the temperature of the heated areas, requires the verification of the work of the installations in the form assessment of the places of the formation of ice accretions rate and their size. To measure them in the mentioned about tests the authors applied the photogrammetric method, and the obtained results were verified with flight tests, including certified tests. The application of the photogrammetric method in such analyses with the example of processing of the obtained pictures gives base for the assessment of its usefulness and the directions of development in similar applications.
