What is it about?
In a partnership with the German Aerospace Center (DLR) and under financial support of Brazilian Space Agency, Brazilian Institute of Aeronautics and Space (IAE) is developing the L75 engine project. This project aims to develop, build and qualify a biofuel liquid propellant engine demonstrator. This paper covers the turbopump development plan and activities related to the current phase of the L 75 Engine project. It also introduces the strategy adopted for components performance verification and presents an approach for seals and bearings project solution investigation.

Why is it important?
The turbopump assembly (TPA) is the highest loaded engine component with a large number of interrelated design elements. The use of the ethanol, as a fuel, has a considerable impact on the design and development of the fuel pump, turbine, turbopump seals and bearings
Perspectives
Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. A big effort was made to join together a highly professional team from both sides of the Atlantic in order to develop a green propellant Engine.
