At Perm Polytechnic University (PNIPU), a method for designing a blade structure with variable geometry has been created. It allows you to automatically adapt to changes in loads at any time. This was reported by the press service of the university.
The development includes three software blocks. A mathematical model for calculating blade deformation at specified parameters. Construction of an experiment matrix to visually demonstrate their operation under different loads. The third block is for calculating the structural parameters of the blade when the twist angle changes.
Controlling the twist angle can prevent the occurrence of turbulent flow along the blade wake, reduce noise and vibration of the helicopter rotor. We have identified the main variable parameters of the blade design with various skin materials.
Earlier www1.ru reported that Rostec replaced with domestic analogues control and autopilot systems of the Ansat helicopter.
