The CL-20 flame structure at pressures of 0.1 and 0.5 MPa was studied using probing molecular beam mass spectrometry. At a pressure of 0.1 MPa, the gaseous products near the surface of the foamy carbonaceous carcass were found to contain eight species: NO, NO 2 , CO, CO 2 , N 2 , H 2 O, HCN, and HNCO. At a pressure of 0.5 MPa, NO 2 was not found and the concentration profiles of the remaining seven species were measured versus the distance to the carbonaceous carcass. In the CL-20 flame at a pressure of 0.5 MPa, consumption of N 2 and CO 2 with the formation of NO and HNCO occurred in a zone of width ≈0.8 mm from the surface of the carbonaceous carcass. At a pressure of 0.5 MPa, the composition of the gaseous combustion products of CL-20 at a distance of 3–4 mm differed from the composition at thermodynamic equilibrium. Key words: flame structure, CL-20, probing molecular beam mass spectrometry.
