DESCRIPTION:Come to hear from Dr Paul Bruce\, Senior Lecturer in High Spee
 d Aerodynamics at Imperial College London\, about his research in the area
 s of unsteady compressible flow\, high speed flow control and turbulence!\
 n\n"Entering a planet’s atmosphere from space and landing safely on its 
 surface is a significant engineering challenge. For more than 60 years\, e
 ngineers have tackled this problem\; developing atmospheric entry vehicles
  with an impressive track record of returning cargo and humans to Earth\, 
 and even sending (unmanned) missions to land on the surface of Mars. Howev
 er\, as our aspirations and ambition for exploring space grow\, mission re
 quirements are evolving beyond the capabilities of existing tried-and-test
 ed hardware and a new generation of atmospheric entry vehicles is required
 . In this seminar\, I will present the results from an ongoing project at 
 Imperial to tackle some of the challenges of landing humans safely on the 
 surface of Mars. The work centres on the development of a reduced-order mo
 del to capture the unique aero-elastic behaviour of this new class of vehi
 cle as it negotiates the re-entry environment. I will try to provide answe
 rs to the following questions: How do we model atmospheric entry? Why is l
 anding humans on Mars so difficult? What are the most promising candidate 
 technologies for doing so? How do we design optimal large diameter aero-de
 celerator heat shields? Why do we need a coupled aero-structural solver? W
 hat are the potential challenges and benefits of designing flexible spacec
 raft? My goal in this talk is to provide some insight into the engineering
  challenges of future inter-planetary exploration missions and\, ultimatel
 y\, explain why we believe this warrants a new approach to spacecraft desi
 gn and how we are working towards this goal at Imperial."
