Technology Development for Space Applications

申请的大部分资金是为了进一步开发为ExoMars制造的微型地震仪，使其适合用于穿透弹任务。这包括电子开发，在不影响噪音性能的情况下减少功耗，以及坚固耐用，使它们能够经受住冲击。硅微结构是地震仪的核心，由帝国理工学院建造。这里详细介绍的工作包包括地震仪的电子设备、包装和测试。多年来，牛津大学一直在为未来的飞行任务开发微型光谱仪。光学设计是由弗朗西斯·莱宁格领导的，他以前是研究生，现在是牛津大学的访问学者。弗朗西斯为卡西尼-VIMS和Rosetta-VIRTIS光谱仪提供了光学设计。他的最新干涉仪设计使用商用探测器、非常宽的波长覆盖范围和低成本的光学制造，提供了卓越的噪声性能。该仪器目前正在牛津大学使用，并处于马可波罗的基线有效载荷范围内。它也是我们为木星木卫三轨道器建议的奥蒂斯仪器上红外通道的最有力候选者。如果扫描和控制子系统在不久的将来达到高技术准备水平，该仪器可能准备好在ExoMars 2016轨道器上使用。除了声学风传感器外，ExoMars AEP气象学包的牛津部分现在已经非常成熟，在为任何新的任务机会提出这一点之前，不需要进行重大的技术开发。然而，我们最近完成了一批新的热风传感器和新设计的声学传感器的制造。工程科学部的风洞在今年剩下的时间里仍可供我们使用，因此我们请求提供少量支持，以结束这些子系统的测试。

The bulk of the funding requested is to develop further the miniature seismometers that have been built for Exomars to make them suitable for use on penetrator missions. This involves electronic development to reduce power usage without compromising noise performance as well as ruggedisation to allow them to survive impact.The Silicon microstructures that are the core of the seismometers are built by Imperial college. The work packages detailed here cover the seismometer electronics, packaging and test. Oxford have, for a number of years, being developing miniature spectrometers intended for future flight missions. The optical design of these has been led by Francis Reininger, an ex Graduate student and now visiting fellow at Oxford. Francis produced the optical design for Cassini-VIMS and for the Rosetta-VIRTIS spectrometer. His latest interferometer design offers superior noise performance using commercially available detectors, very wide wavelength coverage and low cost optics manufacture. This instrument is currently being breadboarded in Oxford and is in the base-line payload for Marco Polo. It is also our strongest candidate for the infrared channels on the proposed ORTIS instrument for Jupiter Ganymede Orbiter. The instrument could in-pirinciple be ready for use on the Exomars 2016 orbiter if the scanning and control sub-systems are brought up to a high technical readiness level in the near future. The Oxford portion of the Exomars AEP meterological package is, with the exception of acoustic wind sensors, now very mature and no significant technology development is needed before proposing this for any new mission opportunities. We have, however, recently completed fabrication of a new batch of thermal wind sensors and a new design of acoustic sensor. The Engineering Science department's wind tunnel remains available to us for the rest of this year so we request a small amount of support to bring the testing of these sub-systems to a close.
