摘要： A nozzle allowing the reduction of noise generated by aircraft jet engines having at least one output ring which disturbs the propulsion jet, and having at least one pair of conduits from which the propulsion of jet air is ejected at the output of the nozzle. The conduits of each pair are disposed convergent with respect to each other in order to generate a triangle of interaction of the air jets at the output ring.

摘要： An aircraft jet engine with a longitudinal axis, including a wall enclosing a gas flow ejected from a downstream end of the wall in the longitudinal axis, plural ducts being distributed around the periphery of the downstream end of the wall each including a terminal section, including an outlet opening. Each duct can eject a fluid jet through the outlet opening thereof. The ducts are configured to eject the fluid jets essentially parallel to each other, each fluid jet ejected through the corresponding outlet opening forming a lateral angle with the longitudinal axis in a projection view in a plane with the longitudinal axis.

摘要： A connector arrangement comprises a rigid inner conductor (107), a dielectric sleeve (111) arranged around the inner conductor and a rigid outer conductor (109) arranged around the sleeve. A surface of at least one of the inner conductor, the sleeve and the outer conductor is provided with a taper, such that the sleeve fixes the relative transverse positions of the inner and outer conductors at a first end of the arrangement and not at a second end of the arrangement. The inner conductor is longitudinally slidable relative to the outer conductor. Such an arrangement is suitable for use in hostile environments, such as in high temperature pipelines, in which there are large temperature variations and in which the positional variation of mating connectors is high.
