| Abstract: | Optics measurement method applied to measure the hot deformation of aeroengine nozzle at minimum mechanical diameter was proposed. Firstly, the variation of deformation on the second row flap exit edge was measured using optics device. Subsequently, the nozzle hot deformation at minimum mechanical diameter was calculated according to the variation. The method could provide significant reference for the design and improvement of the nozzle. |
