DmitriKozlowsky Posted October 27, 2022 Posted October 27, 2022 Dust filter and particle separator in Apache powerplant. As there is no startup check item or pilot control, that I am aware off, for engine FOD protection, it has to be an automatic item. Is that the case in DCS: AH-64D? KA-50, MI-24, Gazzele, there are power ON/OFF or operate switchology.
ED Team Raptor9 Posted October 27, 2022 ED Team Posted October 27, 2022 The T700-series engines have an integrated air particle separator (APS) system. Airflow is directed through a series of vanes in the inlet and into a "swirl frame" which uses centrifugal force to separate dust and particles into the APS. Dust and FOD would have to make it past a "dogleg" of sorts to get to the compressor itself. The entire system is integrated into the function of the engine. However, this isn't a 100% solution to prevent FOD or sand degradation of the engine. The only way any engine can achieve that is to physically block such particles from even entering the inlet, which can be done to a good extent using inlet filters or air particle separators over the inlet, but these will also restrict air flow and will typically create negative impacts to the engines overall performance. Some examples: filters on a Blackhawk and IPS on a Chinook: 2 Afterburners are for wussies...hang around the battlefield and dodge tracers like a man. DCS Rotor-Head
