ROTATING MACHINES ENGINEERING

Turbomachines and drives are complex systems essential for energy generation and propulsion. The only way to achieve their highest possible efficiency, reliability, and safety is to perfectly adapt the rotating machine design to its specific application (size, fuel, working fluid).

Extensive computational analysis and experimental investigation are fundamental for rotating machine development. In practice, it relies on well-known principles but massively benefits from the latest technological insights.

At Inpraise systems, we respect and embrace these facts to provide comprehensive design, prototyping, and analysis for rotating machine systems covering generators, drives, bearings, seals, motor controllers, and test benches.

ENGINEERING AND DEVELOPMENT SERVICES

If you intend to accomplish R&D or product development projects, you may require support in the form of expertise or increased development capacity. Especially if this subject is not the central focus of your business activity.

We will complement your development team by providing R&D support and custom engineering services, whether you need the assurance of professional partnership, including representation and liability throughout the project, or dedicated supplementary assistance.

DESIGNING SMART TURBOMACHINERY

Our practice taught us that inherent qualities such as safety, robustness, sustainability, notably in the case of complex machines, cannot be reduced to a specific function or small group of functions expressed as inputs and outputs in the functional hierarchy of a machine system.

We always address the challenges we are facing from an “outside the box” perspective. Our insight has led us to collectively embrace a careful stance, yet which is fundamentally flexible at its core.

We are passionate about projects representing a seemingly inevitable discrepancy between required parameters, as they allow us to achieve exceptional results.
