APUs are compact engines that start the main engine and provide electrical power and compressed air to support aircraft systems – such as air for cabin temperature control, powering and cooling for avionics and emergency power to re-start the main engines in-flight. The next-generation APU is projected to have the highest power density on the market, delivering maximum performance at a reduced form factor and weight, driving new capabilities for fixed-wing and helicopter platforms.
"Advanced APUs are essential for both defense and commercial aviation, delivering the reliable, efficient power needed to keep aircraft mission-ready on the ground and optimized for performance in the air," said Jessica Villardi, vice president of Fighter and Mobility Programs at Pratt & Whitney. "This work with PBS underscores Pratt & Whitney's commitment to our customers and our focus on developing next generation turbine technologies to support future industry needs."
The next-generation APU is designed to be significantly smaller and lighter than traditional APUs in the same power class and capable of rapidly starting and operating at high altitudes. This will enable new aircraft design opportunities and additional capabilities across military and commercial applications, including additional electrical power, enhanced thermal management and electronic warfare technologies.
"There are only four companies in the world that are authorized to develop and certify civil APUs. PBS Velká Bíteš, a member of the PBS GROUP, is one of them – and that is why we are now joining forces with one of the most important players in the field to jointly develop a new generation of APUs. We are leveraging the best of our know-how and that of our collaborator to advance the technological capabilities of APUs for future civil and defense projects," said Milan Macholán, CEO of PBS Velká Bíteš.
RTX has been producing APUs for decades, using its strong foundation as a major supplier of gas turbine engines to drive innovation for commercial and military propulsion solutions. Similarly, PBS has a long tradition in this field, having developed and manufactured auxiliary power units since the 1970s, i.e., for more than 50 years. During this time, it has gained extensive experience covering the entire process, from development, calculations, and design, through technology, production, and installation in aircraft, to service and overhaul.
