Abstract

The method of calculating the nonlinear aerodynamic characteristics of objects from trajectory data, based on the differential correction principle, is well known [N. P. Mende, FTI Preprint No. 1326, A. F. Ioffe Physicotechnical Institute, Leningrad (1989); G. T. Chapman and D. B. Kirk, AIAA J. 8, 753 (1970)]. A modification of this method is proposed here, in which the solution is to be obtained in the form of a spline. This new approach, which has been tested on model problems, can provide a more reliable guarantee of adequacy of the solutions and an improvement in accuracy in cases where the functional relations sought have a complicated form.
