Formalizing Mission Analysis And Design Techniques For High Altitude Ballooning, Jeremy Straub, Ronald Fevig

High altitude balloon (HAB) missions can be and are used to teach concepts related to spacecraft and satellite design. A HAB mission, however, presents unique characteristics, which must be understood and respected to produce a desirable outcome. Because of this, flying an unaltered satellite design as a HAB payload would be as undesirable as utilizing an unaltered HAB design as a satellite. A well-defined process for HAB mission design is thus needed. The process presented mirrors commonly used space mission design processes to facilitate easy transition between the two. It is also comparatively simple, due to the smaller scale of …

Multi-Tier Exploration Concept Demonstration Mission, Jeremy Straub

A multi-tier, multi-craft mission architecture has been proposed but, despite its apparent promise, limited use and testing of the architecture has been conducted. This paper proposes and details a mission concept and its implementation for testing this architecture in the terrestrial environment. It is expected that this testing will allow significant refinement of the proposed architecture as well as providing data on its suitability for use in both terrestrial and extra-terrestrial applications. Logistical and technical challenges with this testing are discussed.

Experimental Evaluation Of Turbine Blade With Potassium Evaporative Cooling, Jessica Townsend
Jessica Townsend
A new method of turbine blade cooling, the Return Flow Cascade, has been developed in which vaporization of a liquid metal such as potassium is used to maintain the blade surface at a nearly uniform temperature. Turbine blades cooled using this technology have lower blade temperature levels compared to that available with conventional air cooling, potentially resulting in higher firing temperatures or a choice of a wider range of materials for the hot gas path. The detailed operation of the Return Flow Cascade is described including fluid mechanic and heat transfer phenomena that occur at high heat flux and gravitational …

Reconfiguration Of The Receiver System For Sodium Doppler Wind/Temperature Lidar, Vardan Semerjyan, Tao Yuan

Sodium (Na) Faraday filters based spectrometer is a relatively new instrument to study sodium nightglow [Harrell et al., 2010] as well as atmospheric chemistry in the mesopause region. Successful spectrometer measurement demands highly accurate control of filter temperature. The ideal operation site for this Na spectrometer would be an isolated location with minimum nocturnal sky background. Thus, the remote and automatic control of the filter temperature is a requirement for such operation, whereas current temperature controllers can only be adjusted manually by the operator. The proposed approach is aimed not only to enhance the accuracy of the temperature control but …
