At the same time, since the threaded hole of the nut 94 is not visible, once the bolt and nut are not connected on time, it is difficult to tighten the two, and the position of the nut needs to be constantly adjusted to align the two.
During the maintenance of aircraft engines, this will prolong the maintenance operation time, increase the cost of aircraft maintenance time, and increase the risk of aircraft delay

One purpose of the invention is to provide the fastening kit which can solve at least one problem in the prior art. The other purpose of the invention is to provide the aero-engine and the air inlet cone thereof. In order to achieve the aim, the fastening kit comprises a mounting groove, a first fastening part and a second fastening part. The mounting groove is provided with a first matching part; the first fastening component is internally provided with an internal thread, the peripheral side of the first fastening component is provided with a second matching part, and the first matching part can be connected with the second matching part to limit rotation of the first fastening component in the mounting groove and shaking in the second direction in a matched mode. The second fastening component is provided with an external thread, the first component and the second component are respectively provided with a connecting opening, and when the first matching part is connected with the second matching part, the connecting openings are aligned with the hole where the internal thread is located so as to allow the second fastening component to enter and are in threaded connection with the first fastening component.
Description
technical field [0001] The invention relates to the field of aero-engines, in particular to an aero-engine, an aero-engine intake cone and a fastening kit thereof. Background technique [0002] The air intake cone of aero-engine has certain requirements for the surface profile, and the fastening kits used for assembly, such as nut parts, cannot protrude from the surface of the air intake cone. The existing air intake cone is provided with a fastening kit, in which the nut is embedded in the base. However, once the thread of the structure fails, the nut and the embedded base need to be replaced together, which is costly. . [0003] In order to save the maintenance cost, the existing aero-engine design also provides a figure 1 Form of fastening kit shown. The bolt 91 fixes the object 92 to be fixed to the base 93, a hole 930 is opened on the base 93, and a cylindrical nut 94 is placed in the hole 930, and the nut 94 cooperates with the bolt 91 to achieve the purpose of fixi...
