Abstract
To generate an unpolluted high enthalpy air blast of several seconds duration a mass of feed air intended to constitute the high enthalpy air blast is preheated to a given temperature and stored at a given pressure in an elongate confinement tunnel with thermally insulative walls. A downstream orifice of the tunnel is kept closed and a blast of high-pressure air is applied to the upstream end of the mass of feed air to compress it quasi adiabatically to obtain a feed air temperature of at least 1,800K. The downstream orifice is opened and application of the high-pressure air blast is continued whereby the mass of feed air is expelled through the downstream orifice in the form of a feed blast, the temperature of which remains constant for several seconds.
