The Vinci upper-stage engine on the P4.1 test bench at Lampoldshausen

With the help of tests on the P4.1 al­ti­tude sim­u­la­tor, DLR en­gi­neers have as­sist­ed with the com­ple­tion of the de­vel­op­ment of the en­gine de­sign and achiev­ing the qual­i­fi­ca­tion of the Vin­ci high-lev­el en­gine for flight op­er­a­tions. The P4.1 test stand is the on­ly one in Eu­rope able to pro­duce a per­sis­tent vac­u­um dur­ing a test in which the en­gine and its noz­zle can op­er­ate at a sim­u­lat­ed al­ti­tude of over 70 kilo­me­tres. DLR is test­ing the Vin­ci en­gine on be­half of Ar­i­ane­Group.

With the help of tests on the P4.1 altitude simulator, DLR engineers have assisted with the completion of the development of the engine design and achieving the qualification of the Vinci high-level engine for flight operations. The P4.1 test stand is the only one in Europe able to produce a persistent vacuum during a test in which the engine and its nozzle can operate at a simulated altitude of over 70 kilometres. DLR is testing the Vinci engine on behalf of ArianeGroup.
