The aim of the Clean Sky project Palace is to develop a new pump architecture to equip the cooling systems of the next generation of aircraft generators.
There is absolutely no doubt that the future generation of aircraft will require electrical generators that deliver more electrical power and the pumps installed in the aircraft cooling systems will have to be enhanced accordingly. Serv, a French pump designer and manufacturer, Cetim and Thales Avionics Electrical Systems (TAES), Topic Manager of the European project Palace (Pump Architecture Linked to Aircraft Cooling Expectations), have risen to this challenge.
With funding from the Clean Sky programme, this project aims to develop a new pump architecture to cool the future generation of generators. This is no easy feat as this pump must be smaller and lighter than current models while meeting demanding conditions including a minimum flowrate of 23 litres per minute, a rotation speed of 12,000 to 30,000 rpm, an operating temperature range of -40 to +120°C and withstanding all pressure variations between 0 and 55,000 feet!
