Abstract

A landing gear assembly for an aircraft, the landing gear assembly comprising: a forward brace having a first end for attachment to an airframe of the aircraft, and a second end; an aft brace having a first end for attachment to the airframe of the aircraft, and a second end, wherein the second end of the aft brace is coupled to the second end of the forward brace; an actuator piston having a first end and a second end, wherein the first end of the actuator piston is pivotally attachable to the airframe of the aircraft; a bellcrank linkage having a first end, a second end, and a pivot point between the first end and the second end, such that a first portion of the bellcrank linkage extends from the first end to the pivot point, and a second portion of the bellcrank linkage extends from the pivot point to the second end, wherein the pivot point of the bellcrank linkage is pivotally attachable to the airframe of the aircraft, and wherein the first end of the bellcrank linkage is pivotally coupled to the second end of the actuator piston; a primary strut having a first end and a second end, wherein the first end of the primary strut is pivotally coupled to the second end of the forward brace and the second end of the aft brace, and wherein one or more wheels of the aircraft are mounted at the second end of the primary strut; and a secondary strut (e.g. a shock absorber) having a first end and a second end, wherein the first end of the secondary strut is pivotally coupled to the second end of the bellcrank linkage, and wherein the second end of the secondary strut is pivotally coupled to a pivot point near to the second end of the primary strut; wherein the landing gear assembly is configured to adopt a deployed configuration when the actuator piston is in an extended configuration, and wherein the landing gear assembly is configured to adopt a retracted configuration when the actuator piston is in a retracted configuration. Also provided is an aircraft (such as a blended wing body aircraft) having such a landing gear assembly.
