TURBOPROP PROVIDED WITH A BLADE-POSITIONING DEVICE |
摘要 |
The invention relates to a turboprop provided with a blade-positioning device. The invention relates in particular to a turboprop (1) comprising: a stationary nacelle (2), a rotary nacelle (3a) comprising a plurality of blade (5) roots (4), a turbine (6), said stationary (2) and rotary nacelles (3) and said turbine (6) being coaxial on a longitudinal axis x, a blade (5) positioning device (7a) comprising for each blade (5) a means (8) for transforming movement suitable for transforming a translation movement into a rotation movement, each one of said means (8) for transforming movement being secured to said rotary nacelle (3) and being suitable for pivoting a blade (5). Said positioning device (7a) is placed between the inner surface (S2) of said stationary nacelle (2) and the outer surface (S6) of said turbine (6), said positioning device (7a) comprising at least one member (9) comprising a body (10) secured to said stationary nacelle (2) and a rod (11) suitable for sliding along an axis substantially parallel to said longitudinal axis x. The turboprop according to the invention can be used specifically in turboprops provided with two unshrouded counter-rotating propellers. |
