Scramjet nozzle design and analysis as applied to a highly integrated hypersonic research airplane

Engine-nozzle airframe integration at hypersonic speeds was conducted by using a high-speed research aircraft concept as a focus. Recently developed techniques for analysis of scramjet-nozzle exhaust flows provide a realistic analysis of complex forces resulting from the engine-nozzle airframe coupling. By properly integrating the engine-nozzle propulsive system with the airframe, efficient, controlled and stable flight results over a wide speed range

Orbiter/launch system

The system includes reusable turbojet propelled booster vehicles releasably connected to a reusable rocket powered orbit vehicle. The coupled orbiter-booster combination takes off horizontally and ascends to staging altitude and speed under booster power with both orbiter and booster wings providing lift. After staging, the booster vehicles fly back to Earth for horizontal landing and the orbiter vehicle continues ascending to orbit

The Revised Uniform Partnership Act: The Reporters\u27 Overview

This Article is a brief overview of what the Reporters believe to be the four basic contributions of the Revised Uniform Partnership Act (RUPA or Act). First, RUPA changes the law of partnership breakups and gives greater stability to partnerships by abandoning the traditional rule that a partnership is dissolved every time a member leaves. Second, RUPA makes clear that partners are not fiduciaries among themselves in the same sense as disinterested trustees. Specifically, RUPA states that partners legitimately may pursue self-interest without automatically running afoul of their fiduciary duties. On the other hand, RUPA provides an irreducible core of fiduciary duties among partners. Third, RUPA rewrites the rules on the nature and transfer of partnership property. It adopts an entity approach for the sake of simplicity and provides for the filing of partnership statements, including statements of partnership authority, dissociation, and dissolution. Fourth, RUPA for the first time expressly authorizes the conversion and merger of partnerships and provides “safe harbor” rules for those transactions
