Abstract
A helicopter rotor brake assembly for arresting rotational movement of a main rotor drive shaft, wherein the helicopter rotor brake assembly is mechanically interconnected with the main rotor drive shaft through a main transmission. The helicopter rotor brake assembly includes a brake disc rotatably mounted about an axis, wherein the brake disc is mechanically interconnected with the main transmission, and wherein the brake disc defines a plane substantially perpendicular to the axis. A bracket is provided for disposal in combination with the brake disc, and comprises a beam member defining a first end and a second end, a first arcuate member connected to the first end of the beam member and disposed substantially co-planar with the plane defined by the brake disc, and a second arcuate member connected to the second end of the beam member and disposed substantially co-planar with the plane defined by the brake disc. A first caliper subassembly is provided for connection to the first arcuate member, and a second caliper subassembly is provided for connection to the second arcuate member, wherein the first caliper subassembly and the second caliper subassembly are operable, in combin…
