“…However, to the best of the authors' knowledge, there are no studies focusing on the analysis of the role of dynamic pressure conditions on the initiation of corona discharges. This paper tries to fill this gap by analyzing the effect of the rate of climb (RoC) on the inception of corona discharges in air during the climb stage, which is an important stage in the flight of the aircraft [25]. During the climb phase, the atmospheric pressure decreases due to the increase in height, and the air density decreases as well.…”

The combination of the low-pressure environment found in aircraft systems and the gradual electrification of aircraft increases the risk of electrical discharges occurrence. This is an undesirable situation that compromises aircraft safety and complicates maintenance operations. Experimental data are needed to understand this problem. However, most of the published studies are based on static pressure conditions, but aircraft systems are exposed to dynamic pressure conditions, especially during the climb and descent phases of flight. This paper analyzes the effect of dynamic pressure during the climb phase on the corona inception voltage because this phase experiences the worst pressure drop rate. The experimental evidence presented in this paper shows that within the analyzed pressure drop rate range, the dynamic pressure conditions do not have a significant effect on the corona inception value under typical conditions found in aircraft systems during the climb phase.

“…The trajectory optimization in the aircraft departure phase usually aims to reduce the consumption of fuel, impact of noise, and control the required time of arrival (RTA) [5]. Wan et al [6] used the new technology of continuous climbing operation (CCO), and the genetic algorithm to optimize the climb path of the aircraft, then carried out an experimental analysis on the parameters of the trajectory optimization model. Prats et al [7] analyzed the influence of noise when the aircraft took off and established a multi-objective trajectory planning model to solve the optimal trajectory.…”

Synergetic trajectory planning of flights is one of the important goals of trajectory-based operation (TBO), and it is also a method to further improve the utilization of airspace resources with the increasing number of flights in recent years. In order to plan the four-dimensional trajectory (4DT) pretactically and comprehensively, match the flight traffic with airspace capacity, reduce congestion, potential conflicts, and fuel consumption thus improving the efficiency of flights, this paper conducts a method for synergetic trajectory planning in the en-route phase from the perspective of airlines. Firstly, the aircraft performance model, aircraft fuel consumption model, and atmospheric model are constructed according to the base of aircraft data (BADA3.11), and an airspace congestion prediction model is constructed based on the historical flow data of airspace. Secondly, a multi-objective synergetic trajectory planning model is established, and a solution method based on the non-dominated sorting genetic algorithm and simulated annealing algorithm (NSGA3-SA) for the problem of synergetic trajectory planning is designed. The simulation shows that the optimization model and the solution algorithm of NSGA3-SA can reduce fuel consumption by about 4.5% compared to the original flight plans and has a good effect on reducing congestion and avoiding conflicts. The running time of the NSGA3-SA can meet the operational requirements of the pre-tactical trajectory planning. The multi-objective optimization model and the solution algorithm proposed in this paper have great value for the research of flight plan optimization.

“…Compared with the flight cost of the reference trajectory, the RTA constraint is satisfied, and the flight cost of the optimized trajectory is reduced. Wan et al [16] analyzed the green climb trajectory optimization problem under the constraint of a single waypoint. e above research mainly considers the influence of fuel economy, noise interference, or airspace operation restrictions on aircraft flight trajectory.…”

Trajectory-based operation is a new technology that will be developed in the next generation of air traffic management. In order to clarify the optimization space of fuel consumption and emission impact on the environment under the specific operation limitation of air traffic management in the process of aircraft climb, an aircraft climb performance parameter optimization model considering the environmental impact is established. First, the horizontal and vertical climb models are established for the aircraft climb process, and then the optimization objectives are constructed by considering the impact of fuel consumption, exhaust emissions on air temperature, and the convenience of the flight process. Finally, the multiobjective model is solved by genetic algorithm. The B737-800 civil aviation aircraft is selected for simulation experiment to analyze the impact of speed change on the optimization target. The results show that with the change of speed, the fuel consumption and temperature rise are different, and the climb performance parameters of the aircraft are affected by the maximum RTA. By optimizing the flight parameters of the aircraft, it can effectively reduce the impact of flight on the environment and provide theoretical support for the sustainable development of civil aviation.
