PROBLEM TO BE SOLVED: To dissolve a problem such as that a winged flier equipped with an unfolding main wing is high in probability of being intercepted because the area of a radar reflection face is large, in case that it rushes in the air defense range of the target. SOLUTION: This winged flier lessens the area of radar reflection by shutting an unfolding main wing when it rushes in the air defense range of the target.
