1. Normal Burning.-
The study of the rapid propagation of
a region of combustion in explosive mixtures has been made the
object of numerous investigations having in view a greater per-
fection in technique of the explosion engine.
If a mixture of a combustible gas and air contained in a
long tube be ignited, the flame at first proceeds along the
tube slowly and at a regular rate. After being propagated in
this manner, however, for a certain distance, it loses its uni-
form motion and proceeds with accelerated speed and thus may
reach a high velocity.
If, in place of the gas confined in the tube, the explosive
mixture is made to flow through the tube and is ignited at the
orifice, the flame may progress within the tube and against the*From Service Technique et Industriel de V'Aeronautique, Bulletin
