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
Non-equilibrium reacting shock layers. This project aims is to study the non-equilibrium aerodynamic processes involved in hypervelocity flight. The design of vehicles for high speed flight is critically dependent on modelling the interactions between the flow field and the airframe, and the current lack of understanding is restricting the scope and benefit of viable activities in space. The expected outcomes include the ability to design optimised heat shields and air-frames with minimum mass a ....Non-equilibrium reacting shock layers. This project aims is to study the non-equilibrium aerodynamic processes involved in hypervelocity flight. The design of vehicles for high speed flight is critically dependent on modelling the interactions between the flow field and the airframe, and the current lack of understanding is restricting the scope and benefit of viable activities in space. The expected outcomes include the ability to design optimised heat shields and air-frames with minimum mass and maximum payload, precisely targeting specific flight conditions and vehicle shapes. The prospective benefits include increased productivity and reliability and reduced cost of missions to and from space, and a proliferation of new applications which this understanding will facilitate.Read moreRead less
Turbulent heat transfer during Mars Venus and Earth atmospheric entry. This project aims to design better heat shields for spacecraft. Designing heat shields for re-entry vehicles needs good models to predict aerodynamic heating. Conventional wind tunnels cannot measure aerodynamic heating in ground tests in the region of peak heating, making design uncertain and risky. This project will use a free-piston-driven expansion tunnel that can produce flows fast and dense enough to measure heating for ....Turbulent heat transfer during Mars Venus and Earth atmospheric entry. This project aims to design better heat shields for spacecraft. Designing heat shields for re-entry vehicles needs good models to predict aerodynamic heating. Conventional wind tunnels cannot measure aerodynamic heating in ground tests in the region of peak heating, making design uncertain and risky. This project will use a free-piston-driven expansion tunnel that can produce flows fast and dense enough to measure heating for turbulent boundary layers at the highest speeds encountered during re-entry. This should allow scientists to test and develop theoretical and numerical models of heating and so improve spacecraft design.Read moreRead less

By fully taking advantage of excellent affinity of water with polar layered silicate and polar polymer, an innovative approach to fabricate thermally stable polymer/layered silicate nanocomposites via melt extrusion with the aid of water/water vapour will be developed. In this process, the pristine layered silicate will be directly exfoliated into individual layers with nanometer thickness and high aspect ratio, and uniformly dispersed in a polymer matrix. This novel approach is environmentally benign and cost-effective since no alkyl ammonium surfactants are required. The resultant nanocomposites will exhibit excellent barrier properties, high thermal stability, environmental durability and superior mechanical properties. These qualities make them very attractive for many applications in the automotive and packaging industries.Read moreRead less
