Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft technology, specifically to a movable landing gear fairing. Background Technology
[0002] In recent years, with the rapid development of cities and the rapid increase in the population of large cities, existing passenger transportation tools can no longer meet people's needs. In daily life, short-distance transportation or passenger transport often uses ground transportation, such as buses, cars, and trucks. These modes of transportation are often limited by ground roads and frequently experience traffic congestion. In terms of aircraft, manned aircraft are suitable for short-distance transportation and will be widely used and developed now and in the future.
[0003] Existing landing gear fairings are typically connected to the aircraft fuselage with strong links such as screws. This can cause the fairing to be damaged by the deformation of the landing gear when it lands, and in severe cases, it can destroy the fairing. In non-strong link types, there are large gaps between the fairing and the landing gear to absorb the deformation of the landing gear when it lands. However, due to insufficient internal support, this affects stability.
[0004] Therefore, we propose a movable landing gear fairing to solve the above problems. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a movable landing gear fairing. By adopting a structure with no connection at one end, it can better absorb the deformation of the landing gear. The interior is filled with a foam material with good compressibility, which effectively supports the fairing and improves stability. This solves the problems of fairings being prone to deformation and damage, as well as insufficient internal support and poor stability.
[0007] (II) Technical Solution
[0008] To achieve the aforementioned goal of improving fairing stability, this utility model provides the following technical solution: a movable landing gear fairing, including a landing gear and an upper fairing. One end of the landing gear is provided with mounting holes, and multiple mounting holes are provided, extending through the upper fairing into the aircraft. The landing gear is fixedly connected to the aircraft through the mounting holes and can be fixed by detachable fixing methods such as bolts or pins. The upper fairing is fixedly connected to the aircraft. A skid is fixedly connected to the other end of the landing gear. A buffer cover is also fixedly connected to the outside of the landing gear. The buffer cover is used to receive the force generated when the landing gear lands and prevent the landing gear from deforming or being damaged due to the force.
[0009] As a further explanation of this utility model: the upper fairing is horn-shaped, which can better fit the fuselage of the aircraft. One end extends into the buffer cover and is sleeved with the buffer cover. Here, the absence of a fixed connection can better absorb the deformation of the landing gear. The other end is fixedly connected to the fuselage of the aircraft.
[0010] As a further explanation of this utility model: the buffer cover includes an inner fairing and an outer fairing. By dividing the buffer cover into an inner fairing and an outer fairing, the buffer cover can absorb energy through the overlapping method between the inner fairing and the outer fairing when it receives a force. The inner fairing and the outer fairing are fixed together by pins to prevent the inner fairing and the outer fairing from falling off under force.
[0011] As a further explanation of this utility model: a buffer pad is also provided between the landing gear and the buffer cover. The inner and outer sides of the buffer pad are connected to the landing gear and the buffer cover, respectively. By providing the buffer pad, a portion of the force acting on the buffer cover can be absorbed.
[0012] As a further explanation of this utility model: the cushioning pad is foam, which can effectively absorb energy.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides a movable landing gear fairing, which has the following advantages:
[0015] This invention, by adopting a structure without connection at one end, can better absorb the deformation of the landing gear. The interior is filled with a foam material with good compressibility, which effectively supports the fairing and improves stability. This solves the problems of fairing being prone to deformation and damage, as well as insufficient internal support and poor stability. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-2 A movable landing gear fairing includes a landing gear 1 and an upper fairing 2. One end of the landing gear 1 is provided with mounting holes, and multiple mounting holes are provided, extending through the upper fairing 2 into the aircraft. It is fixedly connected to the aircraft through the mounting holes and can be fixed by a detachable fixing method such as bolts or pins. The upper fairing 2 is fixedly connected to the aircraft. The other end of the landing gear 1 is fixedly connected with a skid 4. A buffer cover is also fixedly connected to the outside of the landing gear 1. The buffer cover is used to receive the force generated by the landing gear 1 during landing and prevent the landing gear 1 from deforming or being damaged due to the force.
[0021] The upper fairing 2 is horn-shaped, which can better fit the fuselage of the aircraft. One end extends into the buffer cover and is sleeved with the buffer cover. Here, the absence of a fixed connection can better absorb the deformation of the landing gear 1. The other end is fixedly connected to the fuselage of the aircraft.
[0022] The buffer shield includes an inner fairing 5 and an outer fairing 3. By dividing the buffer shield into an inner fairing 5 and an outer fairing 3, energy can be absorbed when the buffer shield receives force through the overlapping method between the inner fairing 5 and the outer fairing 3. The inner fairing 5 and the outer fairing 3 are fixed together by pins to prevent them from falling off under force. A buffer pad 6 is also provided between the landing gear 1 and the buffer shield. The inner and outer sides of the buffer pad 6 are connected to the landing gear 1 and the buffer shield, respectively. The buffer pad 6 can absorb part of the force acting on the buffer shield. The buffer pad 6 is made of foam, which is good at absorbing energy.
[0023] Working principle: According to Figure 1 , Figure 2 As shown, when landing gear 1 deforms upon landing, the foam is first compressed, absorbing some of the deformation. The remainder is transferred to the inner fairing 5 and the outer fairing 3. Since the upper fairing 2 is fixed to the fuselage and hardly deforms, the deformation here is absorbed by the overlapping of the inner fairing 5, the outer fairing 3, and the upper fairing 2. Therefore, the inner fairing 5 and the outer fairing 3 will not fall off when deformed (the lower end is fixed to the skid 4 with screws, and the upper part is restricted by the upper fairing 2; even if severe deformation occurs, a gap may appear where there is a pin in the middle, but the two pieces will not fall off).
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
