This paper presents a development history of unsteady subsonic lifting surface computation. Our emphasis is restricted to the "pure or conventional lifting surface theory", namely that for out-of-plane motions. The numerical method belongs to "Boundary Element Methods" among various numerical schemes, and so requires only rather little computation cost.<BR>Therefore it seems to be useful continuously in future, even if within somewhat restricted practical purpose. The whole content is divided into several branches-analytical method, kernel function, and numerical method, the last of which is subdivided into mode method, interpolation method, discrete method, and generally applicable techniques. It is emphasized that there are two ways depending on whether chordwise or spanwise integral is carried out first. Now the methods carrying out spanwise integral first are not-so-many, but seem to be remarkably more promising.
