Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance technology, and in particular to a fairing protection device for aircraft wing maintenance. Background Technology

[0002] During aircraft wing maintenance, the upper part of the wing fairing is an exposed area without a protective cover. Therefore, foreign metal objects generated during construction (such as aluminum shavings and scrap metal fasteners) can fall into the fairing's internal structure through this exposed area. If these objects become lodged in critical transmission components, causing control surface malfunction, the consequences can be very serious, posing a safety hazard. Currently, the common practice is to cover the exposed area with appropriately sized plastic sheeting and secure it to the fairing with masking tape to prevent foreign objects from falling inside. However, this method of protection is inconvenient to disassemble and affects maintenance efficiency. Utility Model Content

[0022] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1 As shown, the aircraft wing maintenance fairing protection device of this utility model embodiment includes an intermediate piece 1, a first side piece 2, and a second side piece 3.

[0024] The middle piece 1 has a first side 11, a second side 12, and a bevel 13, with the bevel 13 located at the front end between the first side 11 and the second side 12. A first side piece 2 is connected to the first side 11. The side of the first side piece 2 closest to the middle piece 1 forms a first groove 4 with the bevel 13. A first hook and loop fastener 21 and a second hook and loop fastener 22 are provided on the side of the first side piece 2 furthest from the middle piece 1. A third hook and loop fastener 23 and a fourth hook and loop fastener 24 are provided on both sides of the first side piece 2 extending beyond the front end of the middle piece 1. A second side piece 3 is connected to the second side 12. A fifth hook and loop fastener 31 and a sixth hook and loop fastener 32 are provided on the side of the second side piece 3 furthest from the middle piece 1.

[0025] In this embodiment, the intermediate piece 1 is attached to the upper surface of the fairing, the first side piece 2 and the second side piece 3 are attached to the two sides of the fairing, the first groove 4 is sleeved on the outer periphery of the transmission connecting rod of the fairing, the first hook and loop fastener 21 passes around the lower surface of the fairing and connects to the fifth hook and loop fastener 31, the second hook and loop fastener 22 passes around the lower surface of the fairing and connects to the sixth hook and loop fastener 32, and the third hook and loop fastener 23 passes around the lower surface of the fairing and connects to the fourth hook and loop fastener 24. This protects the exposed areas of the fairing, thereby preventing metal parts from falling into the interior of the fairing.

[0026] Based on the above structural design, the protective device can be easily installed and removed from the fairing, effectively protecting the fairing.

[0027] In some embodiments, the middle piece 1, the first side piece 2, and the second side piece 3 are all canvas pieces. The middle piece 1, the first side piece 2, and the second side piece 3 are fixed together with stitching.
