David F. Williams is a retired engineer living in Huntsville, Alabama, who has spent over 40 years in the determination of quasi-optimum missile trajectories for endo-atmospheric and earth-orbital applications. He now offers his services as a consultant. Please contact him if he can be of any service.
Mr. Williams has developed numerous trajectory optimization computer programs, has developed and analyzed various missile guidance methods for these applications, and has modeled and simulated the performance of a wide variety of missile systems.
Mr. Williams has now developed a rocket design / trajectory optimization program named ZOOM that can be used in conceptual missile design and analysis for intercepts of spacecraft and RV targets, injections into specified conics, and other missions. He has also developed an easy-to-use and inexpensive text encryption program named Cipher Machine. Get more information about these programs here.
