February 2013 Rocket Engineers to Develop New Materials to Improve Space Launchers

European Space Agency and Irish Research Council Sponsor NUI Galway Research

Rocket engineers at NUI Galway are developing new materials which will reduce the cost of launching rockets into space. The European Space Agency (ESA) is cooperating with the Irish Research Council and Irish and European companies to fund the research project.

Two PhD students in Mechanical Engineering at NUI Galway will research innovative methods of using thermoplastic composite materials to reduce the weight of fuel tanks for space launchers.  David Grogan, from Renmore in Galway, and Brendan Murray from Annaglough, Co. Cavan, will work with NUI Galway’s Dr Conchúr Ó Brádaigh and Professor Seán Leen.

Dr Christopher Semprimoschnig of the European Space Agency (ESA) has said that the Agency was delighted to support the work of the NUI Galway researchers: “It costs up to €30,000 to launch 1kg of payload into space. If ESA can reduce the weight of our liquid hydrogen/oxygen fuel tanks on launchers such as Ariane 5 and future launchers, by substituting lightweight composites for metals, this will reduce the cost of telecommunications, internet and satellite television and even help enable manned-missions to Mars and further parts of the Universe.”

David Grogan’s PhD topic is “Finite Element Prediction of Microcracking in Thermoplastic Composite Cyrogenic Fuel Tanks”, and Brendan Murray’s research is on the “Development of Cost-Effective Rotationally-Moulded Polymer Liners for Composite Fuel Tanks.”

The students’ PhD work is jointly sponsored for three years by ESA through its Network Partnering Initiative, and by the Irish Research Council through its EMBARK postgraduate Scholarships. David and Brendan’s work is also supported by ÉireComposites Teo. in Indreabhán, Co. Galway, and Astrium Space Transportation in Bordeaux, France, as well as the Irish Centre for Composites Research at the University of Limerick.
