Abstract:
1. Ramjet engine comprising a combustion chamber, a gas ejection nozzle provided at an end of said combustion chamber, a cruising propulsion means for feeding gaseous fuel into said combustion chamber, at least one air duct means for feeding combustion air into said combustion chamber, a rigid tubular element, an intermediate traverse partition means for dividing said tubular element into two spaces in such a manner that one of said spaces houses said cruising propulsion means and the other space houses said combustion chamber, and passage is cut in said intermediate traverse partition means for feeding of said gaseous fluid into said combustion chamber, wherein said at least one of air duct means is mounted on said tubular element so as to feed the combustion air through the tubular wall of said tubular element, said tubular element is made of a composite material composed of resistant fibers coated with a polymerized synthetic resin and includes insert means for enabling an attachment of an end of said at least one duct means to the tubular element in a vicinity of said combustion chamber, wherein pyrotechnic fuse means are provided for cutting openings in said combustion chamber through which openings said at least one air duct means communicates with the combustion chamber, and wherein said insert means are shaped so as to act as cutting knives to cut the wall of the tubular element upon actuation of the pyrotechnic fuse means.
