This paper presents a comparative analysis of the main hybrid configurations that can be used in the aviation sector, namely, series, parallel and combined. Their features are considered in terms of energy, mechanical and electrical components, and conclusions are drawn regarding the overall complexity of the system, the convenience of energy distribution and losses during various energy transformations. A comparative analysis of the specific energy density of electric batteries relative to high-energy fuel is also carried out, which gives an idea of the feasibility of using hybrid power systems in in vertical takeoff and landing aircraft

“…A research gap exists in the representation of heuristic geometries in a chromosome. Previous studies (Hildemann & Verstegen, 2023) using Genetic Algorithms (GA) have used a directly translated chromosome, with individual genes consisting of the point coordinates that ul-timately comprise the linestring. These solutions, while very effective, have an enormous computational demand.…”

“…An assumption in similar 2D problems is that danger zones extend to infinity in altitude or depth, and route optimisation outputs are bound to a cost surface. However, this is not the case in many scenarios (Hildemann & Verstegen, 2023) and with increasingly agile robotic vehicles the need to exploit such routes becomes clear. Examples in airspace include tunnels and arches, the undersides of bridges and other structures, the tops of buildings and trees, and any navigable zone beneath an overhang or "above" a no-go zone.…”

“…And, to accommodate the development of air traffic and support dense aerial operation, the research trend is gradually concentrating on the exploration of route network planning techniques. Hildemann [17] proposed a multicriteria optimization method to improve urban routes under multiple conflicting objectives. He [18] introduced a route (pipeline) planning method for complex urban environments based on air corridor structure, decoupling the difficult network planning into a singlepath planning problem so as to design a dense and aligned route mesh structure within the network.…”

“…An eVTOL is supposed to operate in airspace that does not interfere with residential life [42]. Currently, the noise of eVTOL varies by model, and since the eVTOL manufacturers do not disclose the situation of noise emission, the Uber Elevate target noise level (i.e., a maximum noise of 62 dB at an altitude of 160 m above the ground) was adopted for the analysis, and the noise pressure was specifically taken to be 100 dB at a reference distance of 1 m. The equation of the sound pressure at ground level was expressed as [17] L p = L m − 20 log 10 (l/l m ).…”

With the continuous opening of low-altitude airspace and the development of aircraft such as electric vertical takeoff and landing (eVTOL) vehicles, urban air traffic has become a sustainable and green development direction for future transportation. Air route networks, as a mainstream design scheme for air traffic, are able to provide prerequisites for eVTOL and other green aircraft to enter urban airspace for safe operation, among which air route planning is a fundamental component of air route network design. Currently, most of the research on aircraft path planning is performed in free airspace, lacking the analysis and processing for the complex operation environment, which has led to the high risk and large operation cost of path planning results, failing to meet the demand for safe and efficient development in the future. Aiming at the above problems, eVTOL-oriented air route planning research was carried out. Firstly, the urban low-altitude airspace structure was planned, and the operational levels of eVTOL were clarified; this was followed by introducing the urban dynamic air–ground risk factors and constructing a dynamic risk assessment model containing risk level information; finally, the improved A* algorithm based on the risk cost was employed to plan the eVTOL air route network, which finally realized the purpose of short path length and low total risk. The simulation results showed that the route generated by the improved A* algorithm could reduce the risk cost by at least 30% with a relatively small path cost, which ensured the operation efficiency and safety of eVTOLs and laid the foundation for the further sustainable and green development of urban airspace in the future.
