European eXPErimental Re-entry Test-bed (EXPERT) is an European Space Agency aerothermodynamics research programme. It was planned that vehicle will be launched on a Russian Volna launch system and will provide knowledge and experience in the design and development of re-entry vehicles.〔(Space cone to acquire expert data )〕 As of 2012, one element in a European Space Agency push to develop vehicles capable of re-entry has been pushed back until at least 2013 as the agency seeks a launch alternative to the Russian submarine-launched Volna rocket which was withdrawn.〔(ESA re-entry test needs new budget after Russian pull-out )〕 One of its main goals was to test materials for ESA’s Intermediate eXperimental Vehicle (IXV), an unmanned, delta-winged plane launched in 2015 aboard ESA’s new Vega small-satellite launcher.〔(European Re-entry Capsule Grounded After Russia Withdraws Launch Offer )〕 Currently EXPERT remains in storage conditions in Turin. == EXPERT Mission Objectives == According to an ESA-ESTEC paper,〔(European Experimental Re-Entry Testbed EXPERT: Qualification of Payloads for Flight )〕 the EXPERT program has the following goals: * Enable in-flight data gathering of selected aerothermodynamic phenomena with high accuracy and reliability * Allow the validation of numerical modeling tools (CFD) and of methodologies for ground-to-flight data extrapolation * Qualify in-flight classical and advanced measurement techniques * Conduct extensive post-flight analyses based on in-flight data, pre-flight numerical databases, preflight ground testing activities. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「European eXPErimental Re-entry Testbed」の詳細全文を読む スポンサード リンク
