The Challenge

A prominent commercial aerospace supplier approached the SEPAC team to design and manufacture a high performance spring engaged brake for a wide body jet platform. The challenge was to design a brake that would have approximately 4-6 times the normal braking capacity of similarly sized devices. High speeds and ultra-fast response time requirements further taxed the parameters of normal design practices.

The Solution

Working closely with the customer's design engineering staff, SEPAC participated in advanced analysis of thermal and magnetic models to begin the development process. After extensive lab testing and multiple iterations of the new concept brake, a qualified design was achieved.


Where typical design and manufacturing processes were not sufficient, SEPAC worked with the customer's materials and process experts to develop new combinations that delivered the higher performance standards of this industry-transforming plane.

The Results

This technology is now a critical safety device in the landing platform operation of one of the world's largest aircraft.


SEPAC continues to play a key role in the evolution of aircraft technology by providing innovative motion control solutions that deliver higher reliability and maintainability for commercial aerospace applications. Our development efforts are focused on expanding the capabilities of brake and clutch technologies as well as the creation of advanced solutions to support the specific needs and applications of our clients.
