“…For the calculation of flight-specific fuel consumption DLR’s Trajectory Calculation Module (TCM) is applied [ 42 , 43 ]. This tool performs a three-degree-of-freedom trajectory simulation with simplified equations of motion, also known as Total Energy Model, and employs the aircraft performance models provided in the BADA (model family 4) [ 44 ]. With TCM, we create a database of reduced flight profiles by simulating aircraft trajectories for all discrete combinations of flight distance (in steps of 100 NM) and load factors (with a higher resolution around usual load factors between 0.75 and 0.85) for all aircraft models available in BADA 4.…”

An explanatory approach to modeling the fleet assignment in the global air transportation system

Airlines’ fleet assignment heavily affects the economic and ecological performance of the global air transportation system (ATS). Consequently, it is inevitable to include potential changes of the fleet assignment when modeling and assessing future global ATS scenarios. Therefore, this article presents a novel explanatory approach to modeling the fleet assignment in the global ATS. The presented approach is based on formulating and solving an optimization problem, which describes the fleet assignment in the ATS through a suitable combination of objective function and constraints. While the objective function combines both the airline and the passenger perspective on the fleet assignment, the constraints include additional operational and technological aspects. In comparison to the available global fleet assignment models in the literature, which rely on statistical approaches, the advantages of the presented approach via an optimization problem lie in the overall scenario capability and the consideration of explicit aircraft types instead of simplifying seat categories. To calibrate and validate our model, we use 10 years of historic flight schedule data. The results underline the strengths and weaknesses of the presented approach and indicate potential for future improvement.

“…In the presented approach, we focus on a generic model capable of processing large ADS-B data sets from different helicopter types to analyse and compare the usage between various fleets. For this purpose, the Eurocontrol BADA-H helicopter performance model was implemented and used [24]. BADA-H was developed to support trajectory and fuel consumption prediction in air traffic management and for environmental analysis.…”

“…If a → ∞, then there is no cycle limit, which is the case for very low torque classes in the original Miner rule. For the definition of the usage reference curve, the parameters are defined with a default flight profile based on the default helicopter procedure in the BADA-H user manual [31]. The created reference profile has a flight time of approximately 17 min and is shown in Figure 3a.…”

Health and usage monitoring systems (HUMS) are the basis for condition-based maintenance of helicopters. One of the most critical systems in terms of safety and maintenance expense that can be monitored by HUMS are the main gearboxes of helicopters with turbine engines. While the health monitoring part of HUMS aims to model the health state from the collected sensor data with advanced algorithms, such as machine learning, the usage monitoring part tracks the time of use and operating parameters of the system, such as load, to determine lifetime consumption. In the presented work, a combination of automatic dependent surveillance-broadcast (ADS-B) flight data with a generic helicopter performance model is used to acquire torque profiles of the gearboxes. With damage accumulation methods, the load spectra are transformed to aggregated indicators that reflect the individual gearbox usage. The methodology is applied to samples of two helicopters from a five-year ADS-B data set of German helicopter emergency medical services (HEMS) acquired for the study. The results demonstrate the feasibility of the generic approach, which can support maintenance scheduling and new usage-based maintenance services independent of direct access to installed HUMS.

“…Additionally, the estimation of the helicopter's performance parameters has been studied to provide a process to obtain certain performance quantities. For example, while the study [8] focuses on estimating the noise, fuel flow, emissions, and required power, the study [9] develops a theoretical model to predict the power coefficients, thrust, and fuel consumption. The estimation of various performance quantities is the main focus of these studies.…”

This paper focuses on robust controller design for a generic helicopter model and terrain avoidance problem via artificial intelligence (AI). The helicopter model is presented as a hybrid system that covers hover and forward dynamics. By defining a set of easily accessible parameters, it can be used to simulate the motion of different helicopter types. A robust control structure based on reinforcement learning is proposed to ensure the system is robust against model parameter uncertainties. The developed generic model can be utilized in many helicopter applications that have been attempted to be solved with sampling-based algorithms or reinforcement learning approaches that take the dynamical constraints into consideration. This study also focuses on the helicopter terrain avoidance problem to illustrate how the model can be useful in these types of applications and provide an artificial intelligence-aided solution to terrain avoidance.
