FIELD: engines and pumps. ^ SUBSTANCE: proposed turboprop comprises propeller with blades secured to annular rotary support adjoining the outer stationary casing enveloping turbine driving said rotary support. Every blade is fitted on pivot to turn relative to rotary support. Gear wheel is fitted on every pivot to engage with driving annular structure making gear wheel fitted to rotate about engine axis about rotary support. Driving annular structure is coupled with outside annular control structure fitted aligned with rotary support via planetary train arranged on rotary support. Planetary train comprises annular spider arranged to rotate on rotary support. Two sets of planetary gears are fitted on said spider. Note here that gears of the first set are located between rim of rotary support and ring gear of stationary casing while gears of the second set are mounted between rim of driven annular support and ring gear of annular control structure. ^ EFFECT: simplified design. ^ 4 cl, 2 dwg |
