Abstract
A thrust enhancing device is disclosed. The thrust enhancing device enhances thrust of a thrust generation part in a state coupled to the thrust generation part configured to obtain a propulsive force by using a reaction force of a fluid. The thrust enhancing device includes a venturi part configured to receive a basic fluid allowed to flow by the thrust generation part and allow the basic fluid to pass through the inside thereof, and an ejection induction part disposed in an inner flow field of the venturi part and configured to linearize a flow of a fluid to be ejected to the outside of the venturi part.
Claims11
A thrust enhancing device, which enhances thrust of a thrust generation part in a state of being coupled to the thrust generation part configured to obtain a propulsive force by using a reaction force of a fluid, the thrust enhancing device comprising:
- a venturi part configured to receive a basic fluid allowed to flow by the thrust generation part and allow the basic fluid to pass through the inside thereof, the venturi part being configured to induce a pressure drop in the inside thereof while the basic fluid passes therethrough, suck a surrounding fluid around the thrust generation part into the inside thereof, and then eject the surrounding fluid together with the basic fluid to increase a total ejection flow rate;
- and
- an ejection induction part disposed in an inner flow field of the venturi part and configured to linearize a flow of a combined fluid of the basic fluid and the surrounding fluid to be ejected to the outside of the venturi part,
- wherein the ejection induction part comprises a direct-ejection inducer fixed in an outlet portion of the venturi part, the direct-ejection inducer comprising a ring-shaped grid plate casing, and a grid plate member provided in a form of a honeycomb and fixed into the ring-shaped grid plate casing, and
- wherein the grid plate member provides straight ejection passageways through which the combined fluid passes in a form of a straight streamline while colliding with the grid plate member.
A thrust enhancing device, which has a combination of a plurality of venturis having different sizes and an identical central axis, the thrust enhancing device comprising:
- a venturi part configured to induce a pressure drop in the inside thereof while allowing a basic fluid to pass therethrough through a central axis portion, suck a surrounding fluid into the inside thereof, and then eject a combined fluid of the surrounding fluid and the basic fluid to increase a total ejection flow rate;
- and
- a direct-ejection inducer fixed in an outlet portion of the venturi part, the direct-ejection inducer comprising a ring-shaped grid plate casing, and a grid plate member provided in a form of a honeycomb and fixed into the ring-shaped grid plate casing, and
- wherein the grid plate member provides straight ejection passageways through which the combined fluid passes in a form of a straight streamline while colliding with the grid plate member.
A thrust enhancing device, which enhances thrust of a thrust generation part in a state of being coupled to the thrust generation part configured to obtain a propulsive force by using a reaction force of a fluid, the thrust enhancing device comprising:
- a venturi part configured to receive a basic fluid allowed to flow by the thrust generation part and allow the basic fluid to pass through the inside thereof, the venturi part being configured to induce a pressure drop in the inside thereof while the basic fluid passes therethrough, suck a surrounding fluid around the thrust generation part into the inside thereof, and then eject the surrounding fluid together with the basic fluid to increase a total ejection flow rate;
- and
- an ejection induction part disposed in an inner flow field of the venturi part and configured to linearize a flow of a combined fluid of the basic fluid and the surrounding fluid to be ejected to the outside of the venturi part,
- wherein the ejection induction part comprises a direct-ejection inducer fixed in an outlet portion of the venturi part, the direct-ejection inducer comprising a ring-shaped grid plate casing, and a grid plate member fixed into the ring-shaped grid plate casing,
- wherein one surface of the ring-shaped grid plate casing includes portions obtained by cutting an end part of the ring-shaped grid plate casing at predetermined intervals in a circumferential direction, and
- wherein the grid plate member comprises a plurality of grid plate members, each having a shape of extending radially from a central portion of the direct-ejection inducer and providing straight ejection passageways through which the combined fluid passes in a form of a straight streamline while colliding with the plurality of grid plate members.
