The author discusses the flame spread over a thermally-thin solid fuel in an opposed, low-speed oxidizer flow under a microgravity environment. Both tasks are directed toward determining the conditions under which the flame can no longer exist, such as blowoff or extinction. The research has direct application to fire safety on spacecraft and to basic questions in combustion. Flame blowoff phenomena are investigated in the theoretical analysis. This analysis employs quasi-steady complete Navier-Stokes' conservation equations and an assumed one-step overall chemical reaction in the gas-phase. When the flame is far from the blowoff limit solid fuel conduction plays only a minor role in the flame propagation over a thermally-thin fuel. However, near the blowoff limit solid phase conduction dominates the process.
