I am currently working on the design and development of a turbojet engine using a turbocharger and need detailed guidance on the control and testing requirements. Specifically, I am seeking information on:

1. Components and instrumentation required for monitoring critical parameters such as thrust, fuel flow, exhaust gas temperature (EGT), and rotor speed.

2. Methods for designing a robust control system for throttle response, fuel injection, and operational stability across varying load conditions.

3. Test rig setup, including considerations for structural stability, vibration isolation, and safety measures for high-speed turbocharger operations.

4. Recommendations for data acquisition systems and software tools suitable for analysing engine performance during testing.

If you have experience in designing or testing turbojet engines, particularly those incorporating turbochargers, I would greatly appreciate any insights, methodologies, or references to enhance the precision and reliability of my project.
