Background

The aircraft canopy is an important component of an aircraft lifesaving system, during flight, canopy glass bears the aerodynamic pressure changing from outside at any moment, and also bears the load in a canopy, and the load is completely acted on a canopy framework poker, so whether the poker can effectively penetrate into a canopy framework hole is a key technical requirement for canopy repair, the canopy glass, a metal framework and a polyester ribbon are easily damaged due to partial penetration, the problems of canopy loss, leakage and the like are caused, and the serious consequences such as canopy glass explosion and the like can be caused in serious cases, so that the flight and life safety is endangered.

The connection form of the cabin cover poker and the framework is shown in figure 1.

As shown in the cross section of figure 1, the cabin cover glass is adhered with a polyester band, and when repairing, a harness cord needs to penetrate into the polyester band, and the harness cord is connected with the cabin cover glass through the polyester band. At present, an airplane needs to be installed by directly using an installation machine, a harness cord penetrates into a polyester ribbon, lubricating grease is coated on the harness cord, and the harness cord is penetrated by force by matching of a plurality of persons.

Firstly, the polyester silk ribbon is made of soft material, the shape of the polyester silk ribbon is not fixed when the polyester silk ribbon is placed in a framework, the resistance is large when the harness cord is penetrated, and the harness cord is difficult to penetrate directly;

secondly, the poker is made of aluminum alloy, the length of the poker is about 1m, the diameter of the poker is about 7.5mm, the deformation resistance is poor, and deformation is easy to generate during threading, so that the poker is difficult to thread and is deflected in threading;

the front end of the poker is conical, so that the metal framework and the polyester ribbon are easily damaged when the poker is worn, the damage is difficult to discover because the poker is an invisible area, and the poker is a potential safety hazard when the airplane flies and can cause flight accidents.

Therefore, a device which can play a role in transition, guide and traction when the canopy poker is inserted is urgently needed at present, and the penetration of the canopy poker is convenient.
