Operational limits

Definition

Operational limits refer to the defined boundaries within which a system, such as a pulse detonation engine, can safely and efficiently operate. These limits are critical for ensuring optimal performance, reliability, and safety during the operation of advanced combustion technologies. Factors such as pressure, temperature, and fuel composition are considered when establishing these boundaries, as they directly affect the engine's performance and longevity.
