Title: Innovations by Joshua J Bracken

Introduction

Joshua J Bracken is an accomplished inventor based in Gilbert, AZ (US). He has made significant contributions to the field of rotorcraft technology, holding a total of 3 patents. His work focuses on enhancing the performance and safety of rotor assemblies.

Latest Patents

One of his latest patents is for rotor assemblies for rotorcraft. This innovative rotor assembly comprises a rotor hub and rotor-blade assemblies. The rotor hub includes rotor-blade supports, with each rotor-blade assembly coupled to a respective rotor-blade support. The assembly features a flap axle, a hub connector, a rotor blade, and a torsion strap. The flap axle extends through a rotor-blade support and has a central flap-axle axis. The hub connector is pivotable relative to the rotor-blade support about the central flap-axle axis, defining a central hub-connector axis. The rotor blade is coupled to the hub connector and is pivotable relative to it, allowing for enhanced maneuverability. The torsion strap connects to the rotor blade and passes through the flap axle, ensuring structural integrity.

Another notable patent is for a damage-tolerant and fail-safe (DTFS) high-strength preloaded pin assembly. This hinge assembly, such as a lead-lag hinge, includes a hinge pin assembly with an outer cylinder and a shear pin. The shear pin extends through the outer cylinder and features threaded ends for securing nuts. The opposing force between the nuts applies compressive stress to the outer cylinder, increasing its resistance to wear and damage. In the event of a complete failure of the outer cylinder, the shear pin maintains the structural integrity of the hinge pin assembly.
