The Flightgear F-14B always had a beautiful 3D model and 3D cockpit thanks to Alexis Bory and Enrique Laso however I felt that the aerodynamics and flight model were not as good and so in August 2014 undertook to fix this using JSBSim and real wind tunnel F-14 aerodynamic data. Recovery procedure is simply to move the throttle for the affected engine to idle and wait for recovery. Monitoring the engine gauges during your scan will allow you to detect a compressor stall by the reduction in RPM. However it is easy to miss this, and particularly on approach when coming in with surplus energy it is possible to keep this in check with rudder and stick and only when increasing power, especially into afterburer, when the yaw moment becomes uncontrollable and an airframe loss is the likely result. When the compressor stalls there will be a small pop (from the corresponding side). Detecting and handling TF-30 compressor stalls ![]() As the compressor stall is based on inlet pressure it is still possible to stall the engine at higher speeds during high G manoeuvering. The compressor stall is simulated based on engine pressures (PB) and the affect of angle of attack and sideslip on the inlet airflow to produce a representative compressor stall. ![]() The TF-30 model includes a configurable compressor stall, including MCB failure. The F-14A with the Pratt and Whitney TF-30 engine is famously sensitive to compressor stalls, and this engine is responsible for many airframe losses.
