A RAPID-scanning Fourier transform-infrared (FT-IR) spectrometer has been set up to study the combustion products evolved from burning a small propellant strand in a windowed test chamber. The windowed test chamber is equipped with a computer-controlled linear actuator, which is employed to fix the vertical position of the burning surface so that steady-state emission and transmission/absorption measurements can be made. Results presented here include emission and transmission spectra of the combustion products generated from a typical heterogeneous AP/HTPB (ammonium perchlorate/hydroxyl-terminated polybutadiene) propellant.
