The ability to compute the maximum area on the earth's surface (footprint) reachable by an autonomous air vehicle can be useful in planning for the vehicle's safe operations. The information can be important when the vehicle experiences subsystem failures causing it to be unable to maintain its nominal performance. In this paper, we present a method to calculate the footprint of a reusable launch vehicle that experiences a failure in one or more of its aero-control surfaces. During a control effector failure, the maximum attainable moments of the vehicle are reduced, which may decrease the range of conditions that the vehicle can maintain a trimmed condition. Additionally, the lift and drag characteristics of the vehicle can change when control effectors are moved to off-nominal positions to correct for moment imbalance caused by failures or damage. As a result, the footprint of the vehicle is reduced. A technique for calculating the available effectiveness of the aero-control surfaces is used in conjunction with a footprint generation algorithm to include the effects of rotational trim on the vehicle footprint.

This book explains and describes re-entry systems for both the Earth and other planets. It provides sufficient information for readers to perform entry mission analysis for different bodies in the Solar System. Not only does it discuss re-entry flight mechanics, but also addresses relevant subsystems and fields, enabling readers to put the information into perspective. The book begins with a complete description of planetary environments, including atmosphere, gravity fields and the shape of the primary body. After a detailed discussion of planar flight mechanics, it then moves on to discuss guidance, navigation, and control, entry, descent, and landing systems, as well as thermal protection systems. It uses examples throughout the text, enabling the theory to be linked to practical applications. Ideal for those wanting an updated, thorough discussion of re-entry systems, this book is suitable for students and researchers.

In this paper, we will examine a configuration for a reusable military launch vehicle (RMLS) concept. This configuration allows for the vehicle to land in an inverted attitude. Such inverted landing improves the turnaround time of the vehicle by reducing the maintenance requirements of the vehicle's thermal protection system. An analysis is performed to examine the impacts by the configuration on stability, control, and footprint for an RMLS configuration.
