Fraunhofer IBP

Fraunhofer Flight Test Facility

Follow us on the virtual tour through the Low Pressure Vessel!

The Fraunhofer-Gesellschaft is the leading organization for applied research in Europe. It employs a staff of more than 26,000, who work with an annual research budget of about 2.5 billion euros. Around 70 percent of the Fraunhofer-Gesellschaft’s contract research revenue is derived from contracts with industry and from publicly financed research projects.


One of the most impressive features of Fraunhofer IBP’s Holzkirchen site is its unique Flight Test Facility (FTF). This comprises a low-pressure vessel housing the front section of an Airbus A310, which is approximately 15 meters long with space for up to 80 test subjects. In the scope of Clean Sky, the flight test facility was extended by a business jet platform. Available test conditions consider the extreme temperatures and the air pressure that can occur inside an aircraft cabin during flights or on ground. The Aircraft Calorimeter (ACC) can additionally expose a unit under test to a thermal shock (extremely rapid cooling) and rapid pressure loss. This test facility enables researchers to study various parameters that influence cabin heat balance by simulating in-flight conditions. The researchers also conduct studies of the aircraft as an overall system by investigating the energy aspects and usage requirements of areas such as the cockpit, passenger cabin, avionics and cargo bay. The team also studies thermodynamic correlations and the build-up of condensation on aircraft components. The passenger experience in the aircraft is furthermore researched for the fields of air quality, thermal comfort and acoustics within Fraunhofer IBP.

Wihtin the 1h workshop a virtual tour through the Flight Test Facility will be conducted with a presentation of recent and current research projects. These include the investigation of moisture uptake in insulations, reduced order avionics temperature map simulation validation, human thermal hazard model and test setups, a subject study to investigate the impact of adaptive ECS on passengers, the novel fire suppression system, a small test chamber for extreme conditions, the bleed air test bench to investigate bleed air contaminants and the Regional Cabin Demonstrator as a future test bench.

The visitor will have the opportunity to visit our lab in a Covid-19 safe environment. We are looking forward to host you!
