Steady detonation regimes in an aerosuspension of aluminium particles is studied on the basis of the mathematical model of heterogenerous detonation with regard for differences in phase velocities and temperatures. The presence of unburned particles in detonation products conditions the sound speed dispersion in the final steady state. The manifolds of existance of Chapman-Jouguet and weak solutions in the plane of relaxation parameters are obtained. Steady-state solutions are tested for stability in the problem of propagation of piston-assisted detonation wave. All steady regimes are stable including the weak regime with a saddle final point. The problem of detonation wave interaction with an adjacent nonequilibrium rarefaction wave at instantaneous removal of thepiston is solved. It is obtained that Chapman-Jouguet and weak regimes including a regime with intermediate sonic final point are self-sustained. Strong regimes are transformed to either Chapman-Jouguet or weak regime depending on the relaxation parameters.
