Abstract:
PURPOSE: An airplane wing equipped with a surface deformation unit and an airplane including the same are provided to decrease drag by keeping the same shape as the surface of a wing when an airplane is on a cruise and to increase lift by being inhaled inward and generating vortex when an airplane takes off and landing. CONSTITUTION: An airplane including an airplane wing equipped with a surface deformation unit comprises an airplane wing(10), a pump, and a control unit. The airplane wing comprises a surface deformation unit(12) provided to an upper skin(11), a chamber, a chamber pressure measurement sensor, and an air pressure measurement sensor, wherein the surface deformation unit keeps flat at the same height as the upper skin according to the pressure inside the chamber to reduce drag acting on the airplane wing when an airplane is on a cruise, or is inhaled inward to generate vortex when an airplane takes off and landing.

Abstract:
A tension control device for an aerostat or balloon and a method for adjusting the location of an aerostat or balloon are provided to maintain uniform tension acting on a connection line connecting the tether cable and the patch attached to the air bladder of the aerostat. A tension control device for an aerostat or balloon comprises a first tension control unit(831) and a second tension control unit(832). The first tension control unit loosens a second connection line(502) connected to the aerostat or balloon when pulling a first connection line(501) connected to the aerostat or balloon and pulls the second connection line when loosening the first connection line so that the tension of the first and second connection lines is balanced. The second tension control unit loosens a fourth connection line(504) connected to the aerostat or balloon when pulling a third connection line(503) connected to the aerostat or balloon and pulls the fourth connection line when loosening the third connection line so that the tension of the third and fourth connection lines is balanced.

Abstract:
The present invention relates to an aircraft including a capsule type mounting cockpit, capable of changing a fuselage by forming a body unit and a flight unit to be able to be separated and only changing a body unit as necessary and of reducing impact transmitted to the body unit by forming an impact fuse and an impact absorbing member in a connection member of a connection unit formed between the body unit and the flight unit.
Abstract:
PURPOSE: A morphing wing for an aircraft is provided to deform trailing edge structure because an actuating linkage connected to a trailing edge is operated by a linear actuator. CONSTITUTION: A morphing wing(1) for an aircraft comprises an undeformable wing structure part(200), a linear actuator(300), an actuating linkage, an upper skin(510), a lower skin(520), and a deformable skin(600). The undeformable wing structure is formed in the opposite side of a trailing edge(100). The linear actuator is positioned in one side of the linear actuator to deform the structure of the trailing edge. The actuator linkage is connected between the linear actuator and the trailing edge to implement a linear motion. The upper and lower skins form top and bottom surfaces arranged between the undeformable wing structure part and the trailing edge and are bent upward and downward according to the motion direction of the actuator linkage. The deformable skin is positioned between the upper skin and the trailing edge and is tensed or compressed.
