“…The testbed used for evaluation was the Transport Class Model (TCM) 22 airframe simulation integrated with two copies of the Commercial Modular Aero-Propulsion System Simulation 40k (C-MAPSS40k) 23,24 engine model in the NASA Glenn flight simulator. 25 The TCM represents a generic, mid-sized, single-aisle transport aircraft with two wing-mounted engines. C-MAPSS40k models a 40,000-lbf thrust class, high-bypass ratio turbofan engine with a representative commercial-type controller.…”

“…This demonstration vehicle generally meets FAA guidelines; so, it provides a valid test environment. 11 In this study, the flight simulation testbed utilized the twoengine transport class Model (TCM) aircraft simulation developed by NASA LaRC 12 and the C-MAPPS40k model developed by NASA GRC for each engine. The integration of the TCM aircraft simulation and the C-MAPSS40k engine simulation is referred to as the TCM with enhanced engine control (EEC).…”

The purpose of this effort is to develop, demonstrate, and evaluate three asymmetric thrust detection approaches to aid in the reduction of asymmetric thrust-induced aviation accidents. This paper presents the results from that effort and their evaluation in simulation studies, including those from a real-time flight simulation testbed. Asymmetric thrust is recognized as a contributing factor in several Propulsion System Malfunction plus Inappropriate Crew Response (PSM+ICR) aviation accidents. As an improvement over the state-of-the-art, providing annunciation of asymmetric thrust to alert the crew may hold safety benefits. For this, the reliable detection and confirmation of asymmetric thrust conditions is required. For this work, three asymmetric thrust detection methods are presented along with their results obtained through simulation studies. Representative asymmetric thrust conditions are modeled in simulation based on failure scenarios similar to those reported in aviation incident and accident descriptions. These simulated asymmetric thrust scenarios, combined with actual aircraft operational flight data, are then used to conduct a sensitivity study regarding the detection capabilities of the three methods. Additional evaluation results are presented based on pilot-in-the-loop simulation studies conducted in the NASA Glenn Research Center (GRC) flight simulation testbed. Data obtained from this flight simulation facility are used to further evaluate the effectiveness and accuracy of the asymmetric thrust detection approaches. Generally, the asymmetric thrust conditions are correctly detected and confirmed.
