1 is a conceptual diagram showing a door system for an auxiliary power unit according to an embodiment of the present invention. 2 is a perspective view showing a part of the door system shown in Fig.

1 and 2, the auxiliary power door system 100 includes a door part 110, a connection part 120, a driving part 130, a guide part 140 and a friction reducing part 150 .

The door portion 110 may be formed in a plate shape and selectively open or close an inlet portion of a suction duct D for guiding air through an auxiliary power unit (not shown). At this time, the door portion 110 can move linearly.

The connection part 120 may be connected to the door part 110. At this time, the connection part 120 may be formed in a link shape, and the connection part 120 may be connected to the door part 110 and the driving part 130 so as to be rotatable.

The driving unit 130 may be connected to the connection unit 120 to linearly move the connection unit 120. At this time, the driving unit 130 may be formed in various shapes. For example, the driving unit 130 may include a cylinder connected to the connection unit 120. The driving unit 130 may include a motor, a spur gear installed in the motor, and a rack gear interlocked with the spur gear. At this time, the rack gear can be connected to the connection part 120, and when the spur gear rotates according to the rotation of the motor, the linear motion can be performed.

Meanwhile, the guide unit 140 may be installed inside the aircraft. For example, the guide portion 140 may be fixed to the inside of the base body. As another embodiment, the guide part 140 may be formed integrally with the base body and protrude from the base body into the base body.

The guide portion 140 may be installed on both sides of the door portion 110. At this time, the guide part 140 can guide the linear motion of the door part 110 when the door part 110 linearly moves. The guide part 140 is disposed between the suction duct D and the base body A so as to guide the door part 110 to linearly move the door part 110 between the suction duct D and the base body A. [ have.

One of the door part 110 or the guide part 140 may include a sliding protrusion 110a. The other one of the door portion 110 and the guide portion 140 may include a guide groove 140a in which the sliding protrusion 110a is inserted and slid. For example, when the door portion 110 includes the sliding protrusion 110a, the guide portion 140 may include the guide groove 140a. In addition, when the door portion 110 includes the guide groove 140a, the guide portion 140 may include the sliding protrusion 110a. Hereinafter, the door unit 110 includes the sliding protrusion 110a, and the guide unit 140 includes the guide groove 140a.

Meanwhile, the friction reducing portion 150 may be installed on at least one of the guide portion 140 and the door portion 110. At this time, the friction reducing portion 150 may be formed in various shapes. For example, the friction reducing part 150 may include a linear motion guide installed in at least one of the guide part 140 and the door part 110. [ The friction reducing portion 150 may include a roller installed in at least one of the door portion 110 and the guide portion 140. At this time, the friction reducing portion 150 is not limited to the above, and may include all materials and all structures that reduce the friction between the guide portion 140 and the door portion 110 when the door portion 110 slides have. Hereinafter, for convenience of explanation, the friction reducing unit 150 includes a roller, which will be described in detail.

In operation of the door system 100, when the auxiliary power unit is operated, the inlet portion of the suction duct D can be opened by linearly moving the door portion 110. More specifically, when the driving unit 130 operates to linearly move the connection unit 120, the door unit 110 connected to the connection unit 120 can linearly move along the guide unit 140. At this time, the sliding protrusion 110a can slide along the guide groove 140a, and the friction reducing portion 150 can reduce the frictional force between the sliding protrusion 110a and the inner surface of the guide groove 140a.

The door part 110 can slide along the guide part 140 to a space between the suction duct D and the base body A and linearly move. At this time, the sliding direction of the door part 110 may be different according to the direction in which the guide part 140 is installed. Specifically, the door unit 110 can linearly move in a direction opposite to the traveling direction of the aircraft. In another embodiment, the door portion 110 can linearly move in the same direction as the traveling direction of the aircraft. Hereinafter, for convenience of explanation, a description will be made in detail about a case where the door unit 110 linearly moves in a direction opposite to the traveling direction of the aircraft.

The door portion 110 can open the inlet portion of the suction duct D when the door portion 110 linearly moves along the guide portion 140. [ At this time, the outside air can be transferred to the auxiliary power unit through the suction duct (D).

When the door portion 110 closes the inlet portion of the suction duct D, the door system 100 of the auxiliary power can operate in the reverse direction. Specifically, the driving unit 130 operates to linearly move the connection unit 120 in the opposite direction. At this time, the door part 110 connected to the connection part 120 can linearly move along the guide part 140. The door part 110 can be drawn out from between the suction duct D and the base body A to close the inlet part of the suction duct D. [

On the other hand, in the case of the door system 100 for a general auxiliary power unit, the door can be opened to open the inlet of the suction duct by operating so as to form a direction perpendicular to the traveling direction of the aircraft or a certain angle. At this time, when the airplane is flying, a load may be applied to the door due to the outside air when the door is opened. Further, the load required for operation of the door portion can be increased due to the load.

However, in the door system 100 for the auxiliary power unit according to the embodiments of the present invention, when the door unit 110 moves linearly in a direction substantially parallel to the traveling direction of the aircraft, The resistance force or the load of the outside air applied to the part 110 can be minimized.

In addition, the door system 100 for the auxiliary power unit can minimize the space required for the movement of the door unit 110 as compared with the conventional system by allowing the door unit 110 to enter between the base body A and the intake duct D .

The door system 100 for the auxiliary power unit can move air similar to the outer surface of the base body A so that the air resistance due to the opening of the door body 110 during operation of the aircraft can be maximized.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover all such modifications and variations as fall within the true spirit of the invention.
