Abstract

To provide a landing gear storage compartment of an aircraft which can protect accessories installed around a landing gear by blocking jet blast and dust etc. while suppressing the weight and the cost. A landing gear storage compartment 3 of an aircraft 1 includes: a storage bay 31 that stores a landing gear 2 for use in takeoff and landing; and a shielding wall 32 , inside of which a wheel assembly 21 of the landing gear 2 stored in the storage bay 31 is arranged, and whose lower side, through which the wheel assembly enters and exits, and whose upper side are opened. An upper opening 32 C of the shielding wall 32 is covered with a partition wall 13 that separates a cabin 12 located above the storage bay 31 , and the storage bay 31.

First claim

What is claimed is:

1. A landing gear storage compartment of an aircraft comprising:
a storage bay that stores a landing gear for use in takeoff and landing;
a partition member that separates the storage bay from an upper zone located above the storage bay; and
a wall body fixed within the storage bay, that has an open portion at an upper side, inside of which a wheel of the landing gear stored in the storage bay is arranged, and whose lower side through which the wheel enters and exits is open,
wherein the wall body and partition member are separate components and the open portion of the wall body is covered with the partition member, and
wherein the wall body has a cylindrical shape and includes a strut opening through which a strut that supports the wheel assembly is passed, wherein the cylindrical shape of the wall body surrounds the periphery of the wheel.

2. The landing gear storage compartment of an aircraft according to claim 1 , wherein the wall body has a circular cylindrical shape and is formed from a metal material by roll forming or stretch forming.

3. The landing gear storage compartment of an aircraft according claim 1 , wherein the wall body is fixed to the partition member that separates the upper zone and the storage bay, further wherein the wall body is fixed to a fairing to thereby support the fairing, wherein the fairing is located around the lower opening of the wall body and reduces aerodynamic drag of an airframe of the aircraft.

4. The landing gear storage compartment of an aircraft according claim 1 , wherein the wall body includes a plurality of panels that are detachably coupled to each other.

5. An aircraft comprising the landing gear storage compartment according to claim 1 .

6. The landing gear storage compartment of an aircraft according to claim 1 , wherein the wall body comprises a shielding wall configured to block jet blast from the wheel.
