The course provides a system-level, integrated method for missile aerodynamic configuration/propulsion design and analysis. It addresses the broad range of alternatives in meeting cost and performance requirements. The methods presented are generally simple closed-form analytical expressions that are physicsbased, to provide insight into the primary driving parameters. Configuration sizing examples are presented for rocket-powered, ramjet-powered, and turbo-jet powered baseline missiles. Typical values of missile parameters and the characteristics of current operational missiles are discussed as well as the enabling subsystems and technologies for tactical missiles and the current/projected state-of-the-art. Videos illustrate missile development activities and missile performance. Finally, each attendee will design, build, and fly a small air powered rocket. Attendees will vote on the relative emphasis of the material to be presented. Attendees receive course notes as well as the textbook, Tactical Missile Design, 2nd edition. Instructor Eugene L. Fleeman has more than 40 years of government, industry, and academia experience in missile system and technology development. Formerly a manager of missile programs at Georgia Tech, Boeing, Rockwell International, and Air Force Research Laboratory, he is an internationally known lecturer on missiles and the author of over seventy publications including the AIAA textbook Tactical Missile Design. What You Will Learn • Key drivers in the missile design process. • Critical tradeoffs, methods and technologies in subsystems, aerodynamic, propulsion, and structure sizing. • Launch platform-missile integration. • Robustness, lethality, accuracy, observables, survivability, reliability, and cost considerations. • Missile sizing examples. • Missile development process. Who Should Attend The course is oriented toward the needs of missile engineers, analysts, marketing personnel, program managers, university professors, and others working in the area of missile analysts, marketing personnel and technology development. Attendees will gain an understanding of missile design, missile technologies, launch platform integration, missile system measures of merit, and the missile system development process. 30 – Vol. 95 $1590 (8:30am - 4:00pm) "Register 3 or More & Receive $10000 each Off The Course Tuition."
