Honeywell Transportation Systems enjoys a strong aerospace heritage. Its predecessor, Garrett AiReasearch, was at the time one of the world’s leading aerospace companies. Over the years, the aerospace connection has grown even more robust, and in 2014, Honeywell Transportation Systems formally became a business unit of Honeywell Aerospace. The collaboration between turbo and aerospace engineers provides Honeywell with a level of expertise unrivaled in the turbocharging industry as shown below:
Honeywell turbo engineers enjoy unique advantages, aided by the transfer of knowledge made possible by more than 30,000 performance maps linked to turbojets and auxiliary power units. Along with sophisticated Auto Optimization tools, this leads to enhanced turbo efficiency at high-pressure ratios and breakthrough innovations such as double-sided compressor wheels.
With turbos spinning as fast as 350,000rpm, stability and reducing friction losses are of critical importance. Aerospace bearing technologies – such as ball bearings – are now being applied to turbochargers, leading to significantly improved transient response, increased fuel economy and better cold-weather performance.
Materials & Process
The synergy leverages expertise in coatings, development of raw material and surface treatment techniques. For Honeywell Transportation Systems, knowledge sharing in this area has resulted in the use of innovative metals, alloys and composites that withstand high-temperature and expand performance profile of materials through increased wear resistance.
Lab and Testing
The knowledge transfer from Aerospace to Turbo business includes mechanical and electric design as well as facility construction. For example, in the recent design of air delivery system for the Turbo lab in Mexico, the Aerospace expertise in this field directly contributed to achieving consistency in air supply while improving overall efficiency.
As CO2 reduction becomes a global imperative, the integration of electrical and mechanical components – as developed for Honeywell aircraft auxiliary power units – has a vital role to play in delivering a more energy efficient and cleaner future.
