The 9eGEN project sees the use of high voltage systems ensuring that helicopters have access to stronger sources of electricity, expecting to increase power efficiency and reduce weight.
The project developed the first prototype model of a 270VDs Generator consisting of two main devices. The first us the 9-phase polygon which is attached to the main gearbox, converting the mechanical power of the main gearbox into electric power at 270VDC. The second component is a Generator Control Unit (GCU) which aims to regulate the power output in order to prevent overvoltage or overcurrent. In these cases, the GCU has built-in capabilities and communication facilities which will help control the situation.
The prototype expects to be launched into the Electro-Generation Distribution System test bench at the Airbus Helicopter site in Marignane, France, with the aim that it will eventually become a part of the RACER (Rapid And Cost Effective Rotorcraft) demonstrator.
RACER is a helicopter with a high cruise speed level of around 220 knots and is a part of the Clean Sky 2 Fast Rotorcraft Innovative Demonstrator Platform. The 270VDC network currently under development by 9eGEN will aid the RACER to be fast, agile and sustainable.
It is expected that introducing high voltage systems in helicopter will result in more powerful electrical sources to impact their power efficiency and weight reduction.
