Undercarriage having a slotted strut
An aircraft undercarriage having a leg for mounting to move on an aircraft structure between a deployed position and a retracted position is provided. The undercarriage generally includes a brace member arranged between the structure of the aircraft and the leg in order to stabilize the leg in the deployed position, and a drive actuator for moving the leg from the deployed position to the retracted position. The brace member includes a strut arm having a proximal end that is designed to be hinged on the structure of the aircraft. The arm presents a longitudinal slot extending until the slot reaches a distal end in order to terminate in a bend and having slidably engaged therein a finger that is secured to the leg, the drive actuator being coupled to the strut arm.
1. An aircraft undercarriage, comprising:
a leg movably mountable to an aircraft structure and carrying at least one wheel, the leg movable between a deployed position and a retracted position;
a brace member comprising a strut arm having a proximal end configured to be hinged on the aircraft structure, the strut arm having a longitudinal slot extending until the slot reaches a distal end and terminates in a bend, the slot having a finger slidably engaged therein and secured to the leg, the brace member arranged between the structure of the aircraft and the leg and configured to stabilize the leg in the deployed position; and
a drive actuator separate from the brace member and coupled to the strut arm for moving the leg from the deployed position to the retracted position.
2. The aircraft undercarriage of claim 1 , wherein the leg and the strut arm are hinged on the structure of the aircraft about parallel hinge axes.
3. The aircraft undercarriage of claim 1 , wherein the finger forms an attachment member for a hook configured to hold the leg in the retracted position.
