Aspects Regarding the Implementation, Capture and Measurement of Noise on the Măgurele Air Test Stand

This paper presents a comprehensive analysis of the air supply system implemented at the Măgurele Air Test Stand, an essential infrastructure for experimental research in noise reduction devices for turbojet engines. The paper meticulously details the system configuration, component integration, instrumentation, and control methodologies designed to simulate realistic engine operating conditions, including subsonic and transonic flow regimes. Experimental procedures focused on evaluating system stability, thermal response, and pressure regulation accuracy, providing critical data for validating the performance of a home-developed air injection system aimed at noise suppression through fluidic chevron simulation. The experimental air supply system at the Măgurele Air Test Stand has proven to be a critical infrastructure for advanced research in noise reduction technologies for turbojet engines. Its precise flow control, robust safety mechanisms, and modular design establish it as an indispensable asset for dynamic experimental setups involving pressure-gain combustion and detonation-based propulsion studies. Therefore, this paper serves not only as a detailed documentation of the existing experimental setup but also as a compulsory reference for future research activities, ensuring that all subsequent experimental investigations build upon a validated and thoroughly characterized technical foundation.
