Helicopter main gearboxes
Currently a series of R&D activities and preparation for production of the VR-442 main helicopter gearboxes to be used for upgrading the MSB-2 helicopters, as well as the VR-17MS for the Mi-8/Mi-17 helicopters, are being conducted. As a result, helicopters will be powered by up-to-date, efficient, more powerful and reliable engines, leading to enhancement of helicopter performance in general.
The development is realized by means of computer-aided engineering.
Main objectives of gearbox development:
minimum overall dimensions
design simplicity and fabricability
high service life
