SGO ITD successfully tested a Liquid Skin Heat Exchanger in flight

Kurzfassung

In September 2014, two flight tests of an experimental Liquid Skin Heat Exchanger (LSHX) have been carried out on the DLR Airbus A320 DATRA (Advanced Technology Research Aircraft). The LSHX test was embedded in a combined flight test campaign of the partners Airbus, Liebherr and DLR. As part of the thermal management stream in the SGO ITD, Liebherr‐Aerospace has developed and qualified this prototype heat exchanger and an experimental liquid loop system which was needed to simulate thermal cabin loads and to feed the LSHX with the cooling fluid on board of the test aircraft. Airbus was in charge of the aircraft integration and of the Flight Test Instrumentation. DLR was in charge to monitor, evaluate and analyse the A/C data as well as to determine the aerodynamic boundary conditions by means of boundary layer rake measurements.
