Within the IAAPS research facilities, we have hot gas stands for studying advanced turbomachinery concepts and waste heat recovery systems. By driving the turbine with heat compressed air, IAAPS can undertake turbomachinery research at temperatures of up to 750°C and flow rates of up to 150kg per hour. Our facility includes the capability of engine flow pulse simulation and the ability to test twin entry systems with unequal intake conditions. The gas stands are designed to be highly flexible with the base capability to cover a wide range of industry’s needs going forward for at least the next twenty years. Within the new IAAPS R&I facility, there will also be an additional three fully flexible cells which can be configured as needed for system and subsystem investigation or future facility growth.
