Summary
This study measured solid propellant combustion temperatures using two remote sensing FTIR methods. Both techniques proved reliable, with spectral line intensity offering a faster, more convenient option for stable combustion.
Area of Science:
- Spectroscopy and Combustion Science
- Chemical Engineering and Materials Science
Context:
- Accurate measurement of solid propellant combustion temperature is critical for performance and safety analysis.
- Remote sensing techniques offer non-intrusive methods for analyzing energetic materials.
- Fourier Transform Infrared (FTIR) spectroscopy provides detailed spectral information for temperature determination.
Purpose:
- To compare two distinct FTIR-based methods for measuring solid propellant combustion temperatures.
- To evaluate the reliability and practicality of each method under varying combustion conditions.
- To identify the most efficient method for real-time combustion monitoring.
Summary:
- Combustion temperatures of solid propellant were determined using remote sensing FTIR at 4 cm(-1) resolution.
- Two methods were employed: maximum spectral line intensity and molecular rotation-vibration spectra of HF.
- Temperatures obtained by maximum spectral line intensity averaged 1788.8 K, while molecular spectra yielded values between 1782.7 K and 1859.7 K.
Impact:
- Both methods demonstrate dependability for solid propellant combustion temperature measurement.
- The maximum spectral line intensity method is identified as more convenient and rapid for stable combustion scenarios.
- Findings contribute to improved diagnostics and control strategies for solid propellant systems.
