Unstable regimes of thermite system combustion

Abstract

The possibility of adjusting the combustion regimes in condensed system combustion without altering the parameters of the system is studied. Results from investigating the influence of the initial thermal impulse, the heat transfer conditions to the surrounding medium, and the forced change in the heat balance on the regularity of unstable combustion are represented. Results of an analysis for the initiation of specified igniters indicate that there exists a definite sequence of changes in the combustion regimes; that certain links in this sequence can be missing; that the passage from stationary to self-oscillatory combustion occurs by a jump; that the multipoint regime is less stable than the spin; and that there exist optimal conditions on the initial thermal pulse.
