The trajectories of round gas jets and jet flames introduced into a sweeping air stream are studied. The influence of various initial conditions and of the physical properties of gases on the trajectory is considered. Experimental verification of the available approximation relations for the trajectories of flames in a wide range of the values of the blowing ratio has been carried out. It is shown that the newly obtained experimental approximation of the trajectory shape differs from the existing ones by about 20%. At small values of the blowing ratio (smaller than ~4.5) the flame trajectories cease to depend on it.
