Advanced Engine Test Cell Facility

Rotron Aerospace’s state-of-the-art on site test facility, including 4 certified engine dynamometer and 150m³ hyperbaric test chamber, is the cornerstone of its commitment to innovation, quality, and performance assurance. Designed to rigorously evaluate engines and propulsion systems under real-world conditions – down to -30 degrees and up to 60,000ft altitude. The facility also includes a wide range of testing protocols including endurance, thermal, vibration, and performance validation. Equipped with advanced instrumentation and data acquisition systems, it enables precise measurement and analysis of engine behaviour across various operational scenarios.

Mature FADEC & Dual Redundant System Architecture

Rotron Aerospace’s MAA-certified FADEC (Full Authority Digital Engine Control) system is a highly advanced and dependable engine management solution, offering precise electronic control over all aspects of engine operation. At its core is an integrated governor control that automatically regulates engine RPM by adjusting fuel and throttle inputs in response to load conditions. This functionality is further enhanced by real-time stoichiometric combustion gas analysis, which continuously optimizes fuel efficiency. These features, combined with Rotron’s proprietary fuel delivery system ensure exceptional performance, operational efficiency, and safety across a wide range of demanding aerospace environments.
