Swiss helicopter developer Kopter made further steps toward final configuration of its light single-turbine SH09 with the flight tests of its new main rotor configuration on its third SH09 prototype (P3), including a modified main rotor head and new main rotor blades, it announced today. The new configuration was tested late last year in its whirltower in Ennetmoos, Switzerland, and installed on P3 in Pozzallo, Italy where Kopter has conducted its SH09 flight-test program since March 2019. Kopter had conducted flight tests of a revised main gearbox (MGB) on P3 last year.
