The UHBR new architecture introduces a gearbox with a dedicated and complex oil cooling system. The solution foreseen in the oil circuit introduces an oil recirculation in order to control, through a three valve outputs, the oil flow provided to the engine and the gearbox. The gearbox system is very sensitive to the oil flow precision and these kinds of valve are not part of SAFRAN legacy, thus a demonstration of capability in terms of flow precision through the all range of oil flow, temperatures and pressures shall be done in order to improve the oil circuit architecture. The objective is to reach TRL 5 by manufacturing 2 prototypes and performing associated demonstration/qualification tests. Please refer to the full topic descriptions document published in this call.
