TheA400M, as the new airlifter of the 21stcentury, will play an essential role in enhanc-ing Europe’s airlift capabilities. The A400Mis scheduled to first fly in 2008 and enter intoservice in 2009.A reproduction of a part of the A400M cargocompartment was arranged in the DuisburgFire Detection Laboratory. The main designand the internal sizes of the mock-up wereapprox. 3,85m x 4m x 9,2m. A ventila-tion system with 16 overhead, 16 floor out-lets and 3 air extraction outlets with filterswas installed.
Smoke tests were performed at the firelab for detector placement. A genera-tor provided the possibility to produce de-fined amounts of smoke. Light obscuration(MIREX) was used as a reference criterion.The goal was to provide as close as pos-sible the real air ventilation conditions be-cause detectors in aircraft cargo compart-ments have to alarm within 60s even underdifficult air conditions.
