PROBLEM TO BE SOLVED: To provide a variable wing structure which is suitable for application to a thin wing since no complicated link mechanism is required, and which can alter and maintain a wing shape without causing weight increase even under a condition that aerodynamic load applied to a wing is large.SOLUTION: A variable wing structure 1 for varying a wing shape includes: a plurality of split wings 2 freely turnably coupled to each other to make the relative angle of each other variable; an oil chamber 3 formed in one of two adjacent split wings 2 and having hydraulic fluid thereinside; a partition member 5 projected to the other of the two adjacent split wings 2 to partition the inside of the oil chamber 3 into two hydraulic fluid chambers 4 and turning inside the oil chamber 3 in response to a change of relative angle; and an oil supply/discharge means for adjusting oil pressure applied to the partition member 5 in each hydraulic fluid chamber 4 by supplying and discharging hydraulic fluid to two hydraulic fluid chambers 4 and changing the relative angle by turning the partition member 5. |
