Embed Size (px)

DESCRIPTION

This is a self-contained three-day short course on the fundamentals of tactical missile design. It provides a system-level, integrated method for missile aerodynamic configuration/propulsion design and analysis and addresses the broad range of alternatives in meeting cost and performance requirements. The methods presented are generally simple closed-form analytical expressions that are physics-based, to provide insight into the primary driving parameters. Configuration sizing examples are presented for rocket-powered, ramjet-powered, and turbojet-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, the development process, and the current/projected state-of-the-art. The attendees will vote on the relative emphasis of the topics. Over thirty videos illustrate missile development activities and missile performance. Finally, each attendee may design, build, and fly an air-powered rocket that illustrates some of the course design methods.

EMD Cost Is Driven by Schedule Duration and Risk

Note: EMD required schedule duration depends upon risk. Should not ignore risk in shorter schedule.-- Source of data: Nicholas, T. and Rossi, R., “U.S. Missile Data Book, 1999,” Data Search Associates, 1999– EMD cost based on 1999 US$
