Abstract
Description
Technical Field
[0001] The present application relates to the field of low-altitude flight safety technology, and specifically to a low-altitude customized route safety system that integrates aerodynamic parameters and meteorological information. Background Art
[0002] my country's low-altitude economic development model is a new type of productivity, centered around unmanned and intelligent operations. It features heterogeneity, high density, high frequency, high complexity, and high intelligence. The technical, management, and safety issues involved are extremely complex, and the challenges they face are even more severe. Traditional aircraft operate primarily in the stratosphere or open areas, where the flow fields are relatively simple. Future urban low-altitude aircraft, such as logistics drones, flying cars, or eVTOLs, will primarily operate in urban low-altitude turbulent zones. Urban skies present a complex, three-dimensional meteorological environment of various scales, primarily including the urban heat island effect and the multidimensional physical environment of wind shear, downbursts, diversion winds, high-rise winds, sea breezes, rain, snow, frost, and so on, generated between densely packed buildings.
[0003] Due to the diverse types, functions, scales, and configurations of low-altitude aircraft, their flow and aerodynamic characteristics are sensitive to external environmental and meteorological factors. Flying through the complex flow fields of low-altitude airspace, characterized by diverse and unsteady wind patterns, scales, and intensities, these aircraft may encounter highly uncertain aerodynamic and flight control issues that are currently difficult to accurately predict, posing a significant challenge to safe flight. Currently, route planning primarily relies on meteorological monitoring and airspace control. Based on large-scale, low-precision meteorological monitoring, primarily using microwave weather radar, low-altitude aircraft in areas facing poor weather conditions face widespread grounding or detours. This crude management approach significantly reduces the efficiency of low-altitude operations. The ability to accurately predict the complex low-altitude airspace flow and environment and their impact on aircraft is fundamental and critical to the development, performance, and flight safety of low-altitude aircraft. Therefore, there is an urgent need to develop a refined safety boundary definition system to enable customized safe route planning for various aircraft with varying performance characteristics.

[0027] The embodiments of the present application solve the problem that current route planning lacks aircraft flight aerodynamic safety thresholds, and thus cannot complete customized, accurate and safe route planning, by integrating the aerodynamic parameters of low-altitude aircraft with refined meteorological information and comprehensively integrating various information considered in current route planning.

[0029] A customized low-altitude route safety system is being constructed that integrates aerodynamic parameters and meteorological information to enable personalized safe route planning for various aircraft with varying performance capabilities. This system consists of two key components. First, it aims to capture the detailed aerodynamic performance parameters of aircraft deployed at low altitudes. These parameters, known as the aerodynamic parameters of low-altitude aircraft, are the "genes" of the aircraft, determining its safety thresholds. Second, it aims to establish a localized, refined wind environment perception network to obtain real-time, detailed wind conditions within the region, providing aircraft with predictive wind conditions. Combined, these two components enable the precise construction of customized safe routes for different aircraft. This system, combined with multiple parameters such as airspace meteorological conditions, air traffic flow, airspace restrictions, terrain and building interference, and the locations of airports and take-off and landing points, along with algorithms such as high-precision positioning, computer vision, and spatial analysis, enables real-time planning and dynamic adjustments of airspace routes, effectively supporting customized, refined route safety planning.
