- Abstract
- A new method for measuring the radiation characteristics of shock-heated air is proposed. The method utilizes shock tube recording equipment to record the radiation power generated by the shock front in the direction of its motion. The experiments were conducted using a DDST-M double-diaphragm shock tube at the Institute of Mechanics, Moscow State University, in the shock wave velocity range V from 8 to 10.6 km/s at a shock front pressure of p = 0.25 Torr. The radiation wavelength range λ = 200–700 nm was investigated, where both molecular bands and atomic lines of nitrogen and oxygen contribute to the radiation. The measured radiation spectrograms were analyzed. The obtained results were compared with those obtained using the traditional time-integrated method, in which the radiation flux is recorded through a window in the side surface of the shock tube perpendicular to the tube axis as a “plug” of shock-heated gas passes the window.
