Radiation and Ablation in Rapidly Expanding Flows. The aim of the project is to record the spectra of radiation from a region of rapidly expanding flow representative of the passage of the shock layer on a re-entry capsule from the windward to the leeward surfaces. The significance of this work is that it addresses a critical area of spacecraft where the uncertainties of our design techniques are of the order of 300 per cent in terms of surface heat transfer, and current vehicles have to use lar ....Radiation and Ablation in Rapidly Expanding Flows. The aim of the project is to record the spectra of radiation from a region of rapidly expanding flow representative of the passage of the shock layer on a re-entry capsule from the windward to the leeward surfaces. The significance of this work is that it addresses a critical area of spacecraft where the uncertainties of our design techniques are of the order of 300 per cent in terms of surface heat transfer, and current vehicles have to use large safety factors to ensure survivability. The outputs from the project will be a data base of radiative parameters which should enable accurate models of the flow to be developed, which is expected to facilitate the design of advanced spacecraft with greater safety and reliability, and with lower structural mass.Read moreRead less
Linear Formation Interferometry for Astrophysics and New Space Technologies. This project will prototype a new type of visible and infrared light interferometry: telescopes freely moving in a line 10s of metres in length and directing their light towards a central beam combiner. This is particularly well suited to sparse aperture optical interferometry from space, which can be used to resolve angular scales much finer than the world's largest monolithic telescopes. The ground based prototype wil ....Linear Formation Interferometry for Astrophysics and New Space Technologies.

This is particularly well suited to sparse aperture optical interferometry from space, which can be used to resolve angular scales much finer than the world's largest monolithic telescopes. The ground based prototype will also be able to make a several key astrophysical observations of benchmark stars and stellar systems, including making precise polarimetric measurements of dust shells around bright stars.Read moreRead less
GRACE follow-on: validation of measurements and initial results. This project aims to advance knowledge to quantify ongoing mass loss of Earth’s polar ice caps and glaciers, increases in sea level, and changes in continental water storage. The project expects to improve the capability to monitor changes on Earth using satellites and to enhance analysis by exploiting data from new instrumentation on the GRACE Follow-On space gravity mission, due for launch in 2018. Expected results aim to improve ....GRACE follow-on: validation of measurements and initial results.

The project expects to improve the capability to monitor changes on Earth using satellites and to enhance analysis by exploiting data from new instrumentation on the GRACE Follow-On space gravity mission, due for launch in 2018. Expected results aim to improve computational tools and to develop expertise to analyse the new data. Other expected outcomes include reliable methods to monitor significant sea-level rise and associated societal and economic disruptions.Read moreRead less
Technologies for space based interferometry. This project aims to develop a new method for laser displacement measurements that will be uniquely suited for use in space. These measurements will enable gravitational measurements of unprecedented accuracy. Missions such as GRACE utilise gravitational observations to provide the distribution of melting polar ice, changes in sea levels, and quantitative estimates of ground water in the world’s food bowls.

These measurements will enable gravitational measurements of unprecedented accuracy. Missions such as GRACE utilise gravitational observations to provide the distribution of melting polar ice, changes in sea levels, and quantitative estimates of ground water in the world’s food bowls. The technique will also allow space-based gravitational wave detectors far simpler than previous proposals. The improved performance, inherent robustness and drastically reduced complexity will enable new classes of missions that would not otherwise be possible. Read moreRead less
