| Summary: | Small sounding rockets often carry scientific instruments to collect data in atmospheric environments. In the context of university-level education and research, their development offers students a hands-on, multidisciplinary platform to study propulsion, aerodynamics, electronic instrumentation, and others. A critical component of sounding rocket experimentation involves engine testing and validation, which typically requires the design and implementation of a dedicated test bench. These test benches are essential for ensuring experimental safety and reliability while enabling the acquisition of accurate performance data. This work presents the design and implementation of a versatile, low-cost data acquisition (DAQ) system specifically developed for a small rocket engine test bench. The system can measure thrust and pressure by interfacing with load cell sensors and pressure transducers. The approach also prioritizes modularity, allowing future expansion or adaptation to different engine configurations. It also balances affordability and functionality compared to commercial DAQs by leveraging cost-effective hardware and software. Experimental testing has demonstrated the system’s ability to deliver accurate and reliable measurements, with noise levels comparable to those of commercial counterparts. These results indicate the system can enable students and researchers to conduct experiments effectively and ensure safety. |
