Propellant DAQ

CHALLENGE

Propellant testing requires precise measurement of rapidly changing chamber pressure during ignition and firing under harsh conditions. Capturing accurate ignition delay, peak pressure, and pressure–time characteristics is challenging due to high dynamics, safety constraints, and signal noise. A reliable, high-speed data acquisition system is essential to ensure repeatable results and meaningful performance analysis.

SOLUTION

  • Integrated pressure sensors for static and dynamic pressure measurement
  • High-speed DAQ hardware with software-controlled monitoring
  • Real-time data logging and P–T curve plotting
  • Robust system design ensuring signal consistency (±10 V range)
