The application discloses a kind of vehicle operating mode transfer planning methods for fuel consumption optimization, comprising: step 1: according to vehicle relevant test operating mode acquisition driving data;Step 2: each variable in the historical data obtained is filtered as different dimensions and is clustered into partitions;Step 3: according to the information extraction of each zone divided by cluster, the relationship and transfer cost of each zone are obtained from continuous operating mode data;Step 4: according to the relationship between each zone, the operating mode transfer directed graph is constructed, and all the minimum cost transfer paths between different initial and final regions are obtained;Step 5: according to the current operating mode and target operating mode information, the region selected by each operating mode in the path is selected as the same as the minimum cost path in step 4 as the optimal transfer path;The operating mode information in the historical data is divided into regions, then each region is regarded as a vertex in the directed graph, the transfer cost between regions is regarded as the distance between each vertex, and the vehicle operating mode transfer path planning is changed into the shortest path search of directed graph.

This invention discloses a performance optimization method for a blade-tip jet hybrid propulsion system based on thermodynamic cycle planning, belonging to the field of aerospace hybrid propulsion technology. The method decomposes the design goals of high power-to-weight ratio and low fuel consumption of an aircraft propulsion system into optimization goals for the system's thermodynamic cycle parameters; identifies key parameters affecting cycle power and thermal efficiency, including compressor pressure ratio, turbine pressure ratio, rotor centrifugal pressure ratio, and blade-tip jet Mach number; collaboratively designs these strongly coupled key parameters and calculates system performance based on component models and energy conservation relationships; compares the calculated system power-to-weight ratio and fuel consumption with the optimization goals, and iteratively optimizes and adjusts component parameters until the optimization goals are met. This invention overcomes the limitations of traditional unidirectional engine design, achieving multi-level utilization and full recovery of system energy, and effectively solves the problem that traditional propulsion systems cannot simultaneously achieve high power-to-weight ratio and low fuel consumption.

This invention relates to the field of aviation technology, specifically to a fuel level monitoring and alarm method for civil aircraft based on ACARS and ADS-B. This method extracts the master flight path from historical ADS-B data, obtains real-time remaining fuel and historical fuel consumption for each flight phase using ACARS data, and calculates the estimated flight time by matching the current flight position with the master flight path. This allows for accurate estimation of remaining fuel at the destination airport, triggering an alarm when the remaining fuel falls below a set threshold. This invention eliminates reliance on airline computer plans and air traffic control flight plans, improves fuel level prediction accuracy by fusing historical and real-time data, reduces false alarms and missed alarms, and supports airports in developing ground support plans in advance. It is applicable to fuel level safety monitoring during civil aircraft flight.
