An attempt to model a working process of ramjet was made. A radiant energy in a pulse periodical regime is supplied in contrast to the classical scheme where the energy in a combustion chamber is supplied continuously by fuel burning. To simulate this problem the Euler equations in the "channel" approximation for a plane case are solved numerically.
Probes for pressure measurement in a pulse wind tunnels prechamber or in a ramjet combustion chamber are posed usually in face of a narrow duct adjoined to the tested volume. Therewith the pressure depends essentially on length of the used duct. At quick unsteady processes de pressure in long ducts is widely smeared in time and the pressure in short ducts has an oscillating character. At that a question on ...
