Abstract: An ignition unit for a turbojet engine, including: an electrical power supply, a single control channel to receive a control signal from a computer, a main sparkplug ignition channel to energize at least one main sparkplug of a main combustion chamber, and an afterburner sparkplug ignition channel to energize at least one afterburner sparkplug of an afterburner chamber. The ignition unit is configured, in response to pulsed controls on the single control channel, to selectively activate the main sparkplug ignition channel or the afterburner sparkplug ignition channel.

Abstract: The disclosure relates to a fixing device for fixing a first part and a second part together. The fixing device may include a nut non-rigidly coupled to the first part. The first part may have a fixing flange with at least one orifice positioned to accept a threaded shank coupled to the second part. A retainer may be proximate an inner diameter of the at least one orifice positioned to retain the nut within the fixing flange before the nut is screwed onto the threaded shank. The nut may have an externally threaded portion which may couple to the internally threaded portion of the orifice in the flange or of an element attached to the flange and to pass completely through the internally threaded portion until it is housed in a cavity for axially retaining the nut. Therefore, the nut may rotate freely before it is fastened to the threaded shank. The disclosure also relates to a turbomachine that utilizes this device and to an associated fixing method.

Abstract: The invention relates to a device for fixing two parts together, a first part having a fixing flange comprising at least one through-orifice for a threaded shank, carried by or integral with a second part, and means for making the nut captive with respect to the flange before it is screwed onto the threaded shank, wherein these means are of the type having a thread, the nut having an externally threaded portion intended to be screwed into an internally tapped portion of the orifice in the flange or of an element attached to the flange and to pass completely through this internally tapped portion until it is housed in a cavity for axially retaining the nut, this allowing the nut to rotate freely before it is screwed onto the threaded shank. The invention also relates to a turbomachine that utilizes this device and to an associated fixing method.
Abstract translation: 本发明涉及一种用于将两部分固定在一起的装置,第一部分具有固定凸缘,该固定凸缘包括用于螺纹杆的至少一个通孔,由第二部分承载或与第二部分一体,以及用于使螺母相对于 在其上的凸缘被拧到螺纹柄上,其中这些装置是具有螺纹的类型,该螺母具有外螺纹部分,该外螺纹部分将被拧入凸缘中的孔口的内部螺纹部分或附接到 并且完全通过该内部螺纹部分直到其容纳在用于轴向保持螺母的空腔中,这允许螺母在旋拧到螺纹柄之前自由旋转。 本发明还涉及利用该装置和相关联的固定方法的涡轮机。
