Includes bibliographical references

Theoretical principles and analytical methodology for the control volume-based energy availability methodology for aerospace vehicles are developed; applications are made to jet-propelled and rocket-propelled vehicles as well as to stand-alone engine systems. Energy availability utilization characteristics of a modeled turbojet engine are studied across a wide range of operating conditions of throttle setting, flight altitude, and flight Mach number. The method is also extended to consider jet-powered vehicles. Fundamental principles regarding entropy generation and energy availability are developed, including directly linking entropy generation and maximum range and endurance of a powered aircraft. Theory and application of the energy utilization methodology with allocation of losses and productive usage are also developed and shown for atmospheric accelerating and climbing (access-to-space) rockets both at specific flight points as well as across missions. Flight conditions required for optimal performance in terms of energy utilization and entropy generation are theoretically derived and verified with applications. Performance impact of entropy generation both in the engine and in the wake on vehicle performance are studied; studies are made for representative rocket systems. In addition, mission-integrated form of the theoretical availability balance formulation has been derived and generalized for an N-stage rocket and cast in both dimensional and non-dimensional forms; theory for special cases and optimization criteria are defined and tested. The primary objective of this work has been to formulate, characterize, and investigate performance of airbreathing and rocket-powered aerospace systems, specifically from the standpoint of energy availability utilization.
