Technology Readiness Level

Technology Readiness Level

Der Technology Readiness Level (TRL), zu deutsch etwa Technologie-Reifegrad, gibt auf einer Skala von 1 bis 9 an, wie weit entwickelt eine Technologie ist. Von der NASA eingeführt, verwendet auch die ESA die Einstufung, um die Einsatzfähigkeit von Raumfahrtelementen abzuschätzen.

Die Beschreibung der Stufen (in Klammern Zeit bis zur Marktreife):

  • TRL 1: Beobachtung und Beschreibung des Funktionsprinzips (8-15 Jahre)
  • TRL 2: Beschreibung der Anwendung einer Technologie
  • TRL 3: Nachweis der Funktionstüchtigkeit einer Technologie (5-13 Jahre)
  • TRL 4: Versuchsaufbau im Labor
  • TRL 5: Versuchsaufbau in Einsatzumgebung
  • TRL 6: Prototyp in Einsatzumgebung
  • TRL 7: Prototyp im Einsatz (1-5 Jahre)
  • TRL 8: Qualifiziertes System mit Nachweis der Funktionstüchtigkeit im Einsatzbereich
  • TRL 9: Qualifiziertes System mit Nachweis des erfolgreichen Einsatzes
