PALACE Project

PALACE is the story of an innovative pump which expects to be implemented in several aircraft used cases. This pump is not a common pump. This pump works whatever the speed of the machines, whatever the temperature range of the fluid, whatever the tank pressure conditioning by the flight level.

PALACE is a great adventure within different teams : SERV a small and medium-sized enterprise which designs and manufactures pumps, and CETIM the Hydraulic and Mechanical Technical Center in France known to help little structures by supporting engineering skills and tools.

Thales Avionics Electrical Systems (TAES) shares this motivating European research program as Topic Manager.

The PALACE project’s aim is to cool the electrical power generators working at variable speed, by transporting the cooling fluid in different conditions.

At the end of the project, after passing the qualification tests specified to comply with aircraft environmental requirements, 2 prototypes (TRL5) will be delivered.

How to guarantee a minimum flowrate of 23 L/min whatever the conditions ?

• A post on LinkedIn
• An article on CETIM website
• Attendance to NAFEMS 2020 November Conference

  

• A video to introduce the project and a second video to highlight conclusions, main results Vs objectives

• Dedicated test bench developed for PALACE project (speed up to 30000rpm, depressurisable tank down to 0.1 bara, oil temperature regulation, delta pressure regulation)

Development tests performed on SERV dedicated PALACE test bench and
performances tests from very low temperature to high temperature, -55°C cold start test, over speed up to 30000rpm, endurance test.
The machining of the Palace pump were carried out by Risoud Industrie.

• An European pump manufacturer with pump architecture skills in direct drive with VFSG generator shaft
• Development of numerical tools dedicated to high speed pump design
• Hydraulic performances compliant with the initial objectives : oil flowrate > 23 L/min with aircraft environmental requirements (range of pressure [0.28 bara ; 1 bara] into oil tank , range of speed 12000rpm up to 25000rpm)
• 5 prototype pumps manufactured for final qualification tests (including 500h endurance)
• IP activities : a patent protects the pump architecture and design
• Additive Manufacturing Proof Of Concept : CETIM performed a demonstrator on a main part of the pump
