Abstract:
A cyclonic fluid separator of the type comprising a tubular throat portion (4) in which a fluid mixture is accelerated to a subsonic or supersonic speed and thereby expanded and cooled down so that condensable components condense and/or solidify and then swirl into a diverging fluid outlet section (5) that comprises an aliter secondary outlet (6) for condensables enriched fluid components and an inner primary outlet (7) For condensables depleted fluid components comprises swirl imparting vanes (2) that protrude tram a central body (1) that extends through at least part of an inlet section of the separator, wherein the central body (1) has, at a location upstream of the throat portion (4), a larger aliter width (2Ro max) than the smallest inner width (2Rn min) of the throat portion (4).
Abstract:
The invention relates to a helicopter provided with a rotor with at least one rotor blade (5), wherein drive means are provided for actively moving the or each rotor blade up and down during rotation of the rotor, in particular about a flapping hinge (8) thereof, so that moments, applied by the rotor to the fuselage (1) are prevented.
