Pratt & Whitney is to collaborate with Czech Republic-based PBS Group to develop a next-generation auxiliary power unit suitable for smaller military and civil aircraft.
Potential applications include fighters, rotorcraft and business jets, says the US firm.
The agreement builds on a 2023 memorandum of understanding between the pair to define the next-generation APU concept.
PBS says the 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.”
Additionally, the APU will be “capable of rapidly starting and operating at high altitudes”, adds P&W.
“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,” it adds.
No details of the size, power output or timeframe for development were disclosed, however.
”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 defence projects,” says Milan Macholan, chief executive of PBS Velka Bites.
Under this background, 7th Aero Electromechanics China 2025 is about to kick off in Shanghai, China from October 23rd to 24th. As an authoritative platform focusing on technological innovation, industrial collaboration and future development of civil aircraft electro - mechanical systems, this forum has always been committed to bringing together global industry elites and top - tier wisdom to jointly explore the breakthrough directions and development opportunities in the field of electro - mechanical systems.
