PROPULSOR BRAKE LOCK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240278923 titled 'PROPULSOR BRAKE LOCK

The abstract describes a propulsor brake lock system for an aircraft, which includes a propeller, a reduction gear assembly, a brake shaft, and a brake assembly. The system allows for the propeller input shaft to be coupled to the reduction gear assembly, which includes an input gear and an output gear. The brake shaft is connected to the output gear and can be engaged or disengaged by the brake assembly, preventing rotation of the output gear, input gear, and propeller input shaft when engaged.

  • The system includes a propeller, reduction gear assembly, brake shaft, and brake assembly.
  • The reduction gear assembly consists of an input gear and an output gear that rotate with the propeller input shaft.
  • The brake shaft is linked to the output gear and can be locked in place by the brake assembly.
  • When engaged, the brake assembly prevents rotation of the output gear, input gear, and propeller input shaft.
  • This system provides a mechanism to lock the propulsor in place when needed.

Potential Applications: - Aircraft propulsion systems - Aerospace industry - Mechanical engineering applications

Problems Solved: - Preventing unwanted rotation of the propeller and associated gears - Enhancing safety during maintenance or storage of aircraft

Benefits: - Improved control over propulsor movement - Increased safety during maintenance procedures - Enhanced efficiency in aircraft operations

Commercial Applications: The propulsor brake lock system can be utilized in various aircraft models to enhance safety and control during maintenance operations. It can also be integrated into new aircraft designs to improve overall performance and reliability.

Questions about the propulsor brake lock system: 1. How does the brake assembly engage and disengage the brake shaft? 2. What are the potential implications of this system on aircraft maintenance procedures?


Original Abstract Submitted

a propulsor brake lock system includes an aircraft propulsor, a reduction gear assembly, a brake shaft, and a brake assembly. the aircraft propulsor includes a propeller having a propeller input shaft coupled thereto. the reduction gear assembly includes at least an input gear and an output gear. the input gear and output gear are both rotatable with the propeller input shaft. the brake shaft is coupled to, and is rotatable with, the output gear. the brake assembly is coupled to the brake shaft and is moveable between a disengaged position, in which the brake shaft may rotate whenever the output gear rotates, and an engaged position, in which the brake shaft is prevented from rotating, thereby preventing rotation of the output gear, the input gear, and the propeller input shaft.
