Abstract
A jet-propelled engine using discharged exhaust gas, includes: a body; a combustor installed in the body so as to spray fuel to compressed air and combust the fuel; a guide member for guiding exhaust gas, discharged from the combustor, in a predetermined direction; and a propulsive force providing means for providing propulsive force by colliding with the exhaust gas guided from the guide member, wherein one propulsive force providing means is provided at the rear side of the guide member.
Claims11
A jet propulsion engine comprising:
- a body defining an axis;
- a combustor mounted in the body and configured to inject fuel into compressed air and combust the fuel;
- a turbine stage disposed at a rear of the combustor and configured to laterally discharge the exhaust gas at an angle of −30° to −50° relative to the axis;
- a guide member positioned downstream of the turbine stage, the guide member being configured to further laterally deflect the exhaust gas from the turbine stage to an angle of −40° to −70° relative to the axis, such that the deflected exhaust gas forms a vortex within the body;
- and
- a single propulsive force providing means positioned at a rear of the guide member and configured to provide propulsive force by colliding with the vortex of exhaust gas guided by the guide member,
- wherein the propulsive force providing means comprises:
- a rotating shaft;
- and
- a single fan blade provided at the rear of the guide member, coupled to the rotating shaft, and shaped to become more parallel to the rotating shaft toward a rear of the body, such that the exhaust gas deflected by the guide member collides with the single fan blade to produce additional thrust.
