In-house Entwicklung, Forschung und Kooperationen
Das IfTA Produktportfolio beruht auf mehr als zwei Jahrzehnten Erfahrung und einer kontinuierlichen Weiterentwicklung durch moderne Forschung.
IfTA verfügt über eine eigene R&D-Abteilung. Ein Hauptziel der Forschungen ist der Gewinn neuer Erkenntnisse über die Ursachen von Schwingungen und deren Vermeidung. Innovative Lösungswege werden mittels unserer Entwicklungen validiert. Unsere Forschung ist die Triebfeder für Produkte, die eine hohe Wirtschaftlichkeit und Qualität erfüllen.
Die IfTA GmbH wurde im Rahmen eines Forschungsprojektes gegründet und auch heute noch spielen Forschungskooperationen eine große Rolle im Unternehmen. Die Zusammenarbeit mit namhaften Universitäten im Rahmen von nationalen und EU-Forschungskooperationen ist dabei ein unverzichtbarer Bestandteil unserer Innovationsstärke.

- Department of Mathematics, Keele University, United Kingdom
- Lehrstuhl für Thermodynamik der Technischen Universität München
- Lehrstuhl für Flugantriebe der Technischen Universität München
- Laboratory of Thermal Engineering, University of Twente, Niederlande
- Institut für Turbomaschinen und Fluid-Dynamik der Universität Hannover
