Beschreibung
Zusammenfassung:	A thrust increasing device (10) includes: a fuel injector (10b) that ejects fuel toward a jet flow; an ignition device (10c) that is disposed downstream from the fuel injector; a cylindrical duct (10a) that surrounds a combustion region; a flame holder (10d) that is disposed in the duct; and a swirling flow generating part (10d) that maintains an axial (L) flow of the jet flow in an axial direction of the duct in an outer region of the duct in a radial direction inside the duct and that converts the jet flow to a swirling flow centered on an axis of the duct in an inner region of the duct in the radial direction inside the duct.
