According to the embodiment of the present invention, as the supplementary thrust generating apparatus used in the having the propulsion device, a technical configuration is provided, which is provided on an outer surface of the object, and converts external pressure applied to the object while the object is propelled in the thrust direction by the propulsion device, and generates a supplementary thrust in a direction which is the same as the thrust direction, so the supplementary thrust can be generated in the direction which is the same as the thrust direction while the thrust (a thrust in a direction in which the object is propelled) is applied to the object (airplane or ship), thereby reducing fuel consumption of the propulsion device or increasing a speed of the object by the supplementary thrust with an output of the same propulsion device.
Further, according to the embodiment of the present invention, a technical configuration is provided, in which the supplementary thrust generating apparatus includes an inner support unit, an outer support unit, and a plurality of thrust conversion units, so when the external support unit is pressed by external pressure applied to the outer support unit, the pressed force can be transferred to the inner support unit while being converted into the supplementary thrust by each thrust conversion unit, and as a result, the object can further receive the supplementary thrust transferred to the inner support unit in addition to the thrust by the propulsion device.
Further, according to the embodiment of the present invention, a technical configuration is provided, in which each thrust conversion unit includes a thrust conversion member, and the thrust conversion member includes one end portion having a long shape placed to be inclined to form an acute angle with respect to the outer support unit in the thrust direction and form an obtuse angle with respect to the inner support unit, and simultaneously placed to be inclined to from the obtuse angle with respect to the outer support unit in an opposite direction to the thrust and form the acute angle with respect to the inner support unit, and provided in the inner support unit, and the other end portion provided in the outer support unit, so when the outer support unit is pressed by the external pressure applied to the outer support unit while the object is propelled in the thrust direction, if thorns which stretched in a diagonal direction, which form a circumference of a male foxtail are grabbed by a hand, the supplementary thrust can be further provided to the object in the thrust direction while the inclined thrust conversion member is pressed while forming the acute angle and the obtuse angle as if the male foxtail moves.
Further, according to the embodiment of the present invention, since a technical configuration is provided, in which each thrust conversion unit further includes a fixation unit and a hinge unit, the pressed force can be smoothly transferred to the other end portion of the thrust conversion member while one end portion of the thrust conversion member is rotated with respect to the outer support unit through the hinge unit while the outer support unit is pressed by the external pressure, and the transferred force can be almost absolutely transferred to the inner support unit through the fixation unit, and even when the external pressure is released, the thrust conversion member is fixed through the fixation unit, so the outer support unit may be moved to an original position so that the thrust conversion member is ready for receiving the external pressure again while a form of the thrust conversion member is restored again by self elasticity of the thrust conversion member.
Further, according to the embodiment of the present invention, since a technical configuration is provided, in which a part or the entirety of an outer circumferential surface of the object form a curved surface, and the outer support unit includes a first outer support section and a second outer support section, the plurality of thrust conversion units includes a first thrust conversion section and a second thrust conversion section, and the first thrust conversion section has two or more thrust conversion members arranged to be parallel to each other and the second thrust conversion section have two or more thrust conversion members arranged to be parallel to each other, when the external pressure is applied to the outer support unit, the supplementary thrust can be smoothly provided to the object through the divided first and second outer support sections and the distinguished first and second thrust conversion sections.

As illustrated in
Accordingly, the supplementary thrust F2 may be generated in the same direction as the direction of the thrust F1 while the thrust F1 (a thrust in a direction in which the object is propelled) is applied to the object (airplane or ship) 10 by the propulsion device, so fuel efficiency of the propulsion device may be reduced or in the case of an output of the same propulsion device, a speed of the object 10 may be increased by the supplementary thrust F2.
Hereinafter, the supplementary thrust generating apparatus 100 according to an embodiment of the present invention will be described in more detail by continuously referring to
As illustrated in
The inner support unit 110 is a component for supporting the supplementary thrust generating apparatus 100 of the present invention on the object 10. The inner support unit 110 may be fixed onto an outer surface 11 of the object 10 as illustrated in
The outer support unit 120 is a component for directly receiving the external pressure applied to the object 10 instead of the outer surface 11 of the object 10. The outer support unit 110 may be provided at an interval from the inner support unit 110 as illustrated in
The plurality of thrust conversion units 130 is a component for converting the external pressure P applied to the outer support unit 120 into the supplementary thrust F2 in the same direction as the direction of the thrust F1, and transferring the supplementary thrust F2 to the inner support unit 110. The plurality of thrust conversion units 130 may be provided between the inner support unit 110 and the outer support unit 120 as illustrated in
Therefore, the components (the inner support unit 110, the outer support unit 120, and the plurality of thrust conversion units 130) are provided, so when the outer support unit 120 is pressed by the external pressure P applied to the outer support unit 120, the pressed force may be transferred to the inner support unit 110 while being converted into the supplementary thrust F2 by each thrust conversion unit 130, and as a result, the object 10 may further receive the supplementary thrust F2 transferred to the inner support unit 110 in addition to the thrust F1 by the autonomous propulsion device.

Therefore, when the outer support unit 120 is pressed by the external pressure P applied to the outer support unit 120 while the object 10 is propelled in the direction of the thrust F1, if thorns which stretched in a diagonal direction, which form a circumference of a male foxtail (or green foxtail) are grabbed by a hand, the supplementary thrust F2 can be further provided to the object 10 in the direction of the thrust F1 while the inclined thrust conversion member 131 is pressed while forming the acute angle θ1 and the obtuse angle θ2 as if the male foxtail moves (not illustrated) (see

Therefore, even though the supplementary thrust generating apparatus 100 according to an embodiment of the present invention is mounted on the airplane 10A having the curved outer circumference surface 11, the plurality of thrust conversion units 130 may smoothly operate with respect to the curved surface. That is, when the external pressure P is applied to the outer support unit 120, the supplementary thrust F2 may be smoothly provided to the airplane 10A through the divided first and second outer support sections 120A and 120B and the divided first and second thrust conversion sections 130A and 130B (see
Furthermore, as illustrated in
Moreover, the outer support unit 120 may further include an outer connection skin 123 as illustrated in
Therefore, since an interval between the first outer support section 120A and the second outer support section 120B is varied through flexible connection of the outer connection skin 123, the outer support unit 120 can sufficiently permit such a change while being bent according to the varied interval, and a space between the first outer support section 120A and the second outer support section 120B can be sealed by the outer connection skin 123, so loss of the external pressure applied to the outer support unit 120 can be minimized, and ultimately, loss of the supplementary thrust F2 can be minimized.
