An approximate method is presented for the determination of the minimum amount of suction necessary to maintain a laminar, attached boundary layer in incompressible, axisymmetric flow. The method is an extension of A.M.O Smiths procedure which calculations a general laminar boundary layer by piecewise similarity solutions. To extension has been programmed on a VAX 11782 computer and found to the extremely fast, taking from 3 to 4 secs. in CPU time. Boundary-layer solutions for four axisymmetric bodies at a variety of Reynolds numbers have been obtained and the results are compared with finite difference solutions which use the suction distribution from the approximate theory. Agreement between the two is generally good.
