Propulsion Systems Ltd is proud to offer our specialized Cold Rolling service for Hartzell Propeller Blades, a process officially approved by the original equipment manufacturer, Hartzell Propeller Inc. Our service is designed to significantly enhance the performance, reliability, and lifespan of your aircraft’s propeller blades through a meticulously controlled cold rolling process.

What is Cold Rolling?

Cold rolling is a precise engineering technique that involves the application of compressive stresses to the surface of the propeller blades. This is achieved by rolling hardened steel rollers over the blade surface at a controlled pressure and speed. The process induces beneficial compressive stresses on the blade surface, which effectively improve its fatigue resistance. This means the blades become more resilient to crack initiation and propagation, which is crucial for maintaining structural integrity under the stresses of flight operations.

Benefits of Cold Rolling:

1. Enhanced Fatigue Resistance: The primary benefit of cold rolling is the significant improvement in the fatigue life of the propeller blades. By inducing compressive stresses, the process mitigates the formation and growth of cracks, a common issue that can lead to blade failure.

2. Improved Performance and Reliability: Cold rolled blades perform better and are more reliable, reducing the likelihood of unexpected failures and the need for frequent inspections and replacements. This leads to improved aircraft availability and operational efficiency.

3. Extended Service Life: The durability of propeller blades is markedly increased through cold rolling, which means longer intervals between overhauls and replacements, resulting in cost savings over the life of the aircraft.

4. Compliance with OEM Standards: Being approved by Hartzell Propeller Inc., our cold rolling services adhere to the stringent quality and safety standards set by the OEM. This ensures that the propeller blades maintain their optimal performance and safety characteristics as intended by Hartzell.

Our Process:

At Propulsion Systems Ltd, we use state-of-the-art equipment and follow rigorous procedures to ensure the highest quality of cold rolling services. Our technicians are highly trained and experienced in handling Hartzell propeller blades, ensuring that each blade undergoes precise and uniform treatment.

1. Inspection: Each propeller blade is thoroughly inspected before the cold rolling process begins. This ensures that only blades in suitable condition are treated, maintaining the highest safety standards.

2. Cold Rolling: Using advanced machinery, our technicians apply the cold rolling process under controlled conditions. The parameters are meticulously set to achieve the optimal compressive stress without compromising the blade’s integrity.

3. Quality Assurance: After cold rolling, each blade undergoes a series of quality assurance tests to verify the effectiveness of the process. This includes checking the surface finish, measuring the induced stresses, and ensuring that the blades meet or exceed OEM specifications.

4. Documentation and Certification: Upon completion, we provide comprehensive documentation and certification for each blade, confirming that it has been processed according to Hartzell Propeller Inc.’s approved procedures.
