Detonation Regime in Combustion of Heptane and Jet A-1 Propellant in a less than 0.5-m-Long Small-Size Combustor

Journal of Engineering Physics and Thermophysics Aims and scope

This paper is devoted to investigating the dynamics of propagation of a combustion wave in a small-size pulse detonation combustor with a length of less than 0.5 m operating on heptane and Jet A-1 propellant. A link has been established between the combustion wave propagation velocity and the pulse detonation combustor thrust and the ratio of the components of a fuel–air–oxygen mixture. The maximum wave velocity and detonation combustor thrust are achieved irrespective of the type of fuel in mixtures of parastoichiometric composition, with the propellant being inferior to heptane in terms of both combustion velocity (more than three times) and the developed thrust (almost two times).
