Embodiment Construction

[0016] The finished airbag is divided into upper and lower airbags. When in use, the upper and lower airbags are combined and stuffed into the flange. After the French finished airbag is combined, it is at position 4 of the Z490 section, and the trailing edge sub-bag surface is biased towards the upper airfoil surface. After forming the tail rotor blade sub-bag surface, glue is squeezed into the junction, and the flange Z167 to the Z490 section (tail rotor blade A 323mm-long glioma trace is formed on the inner surface of the front and rear edges, and the glioma trace is biased towards the upper wing surface.

[0017] The airbag made by domestic tooling is divided into upper and lower airbags. When in use, the upper and lower airbags are combined and stuffed into the flange. The self-made airbag of the domestic tooling is in the Z490 section after the assembly, the rear edge of the sub-bag surface is biased towards the lower wing surface, and the formed tail rotor blade cuff is...

Abstract

The invention belongs to an auxiliary helicopter detection method, and particularly relates to a method for identifying tail rotor blade air bag types through air bag separating face traces. On the premise of not damaging tail rotor blades, by means of an existing inspection method, which one of French finished silica gel air bags, French tool self-manufactured silica gel gags and domestic tool self-manufactured silica gel air bags are used as the tail rotor blades can not be distinguished. Thus, the method for accurately identifying the air bag type on the premise of not damaging the tail rotor blades is needed. In order to go aground as quick as possible and avoiding great economic loss, which one of the French finished silica gel air bags, the French tool self-manufactured silica gel gags and the domestic tool self-manufactured silica gel air bags are used as silica gel air bags used for tail rotor blade forming needs to be identified and determined. By means of the method, the silica gel air bag state used for tail rotor blade forming can be easily, conveniently, visually, rapidly and accurately identified, the go-around requirement of users can be met to the maximum extent, the user aircraft attendance rate is increased, and completion of user flying tasks is ensured.

Description

technical field [0001] The invention belongs to a method for auxiliary detection of a helicopter, and in particular relates to a method for identifying the type of an airbag of a tail rotor blade by using traces of a sub-bag surface. Background technique [0002] The tail rotor blade is composed of three parts: flexible beam, sleeve and airfoil section. The core component of the tail rotor is the flexible beam, which connects the two tail rotor blades in reverse, fixes them to the hub, and forms the girder of the tail rotor blade airfoil section through it. The cuff has a flange molded together. [0003] In order to verify the quality consistency of batch production of tail rotor blades, the life test of batch production of tail rotor blades was carried out. Due to the premature failure of a certain batch of test pieces during the 50,000th test, the subsequent delivery of the tail rotor blade was stopped, which affected the test flight and delivery work. [0004] Through ...
