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.

The invention provides a motorcycle generating load adjusting system which comprises an engine rotating speed sensor, an accelerator sensor, a storage battery, a controller and a voltage stabilization control device, the voltage stabilization control device comprises a communication port, a power input port and a power output port, and the power input port and the power output port are electrically connected with the controller, a generator and the storage battery respectively; the voltage stabilization control device receives engine rotating speed information and accelerator opening degree information transmitted by the controller through the communication port, and converts an induction power supply generated by the generator into a charging power supply of the storage battery, and the charging power supply corresponds to a power generation load; when the voltage stabilization control device judges that the engine rotating speed information falls into a rotating speed interval and the starting speed of the accelerator opening degree information is larger than or equal to the threshold acceleration speed, the voltage stabilization control device reduces the charging power supply so as to reduce the power generation load.

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.

This invention discloses a control method for a piston cooling spray hook, relating to engine control technology. The method involves acquiring the engine's oil pressure and temperature, and combining these to obtain a first oil flow requirement for the oil pump. A second oil flow rate for the piston cooling spray hook is calibrated based on the engine's real-time throttle opening, and the change in oil flow rate of the piston cooling spray hook is obtained based on the change in the second oil flow rate. This change in oil flow rate is then superimposed on the first oil flow requirement to obtain a target flow requirement. Finally, the oil pump is controlled to output an oil flow rate consistent with the target flow requirement. This invention achieves coordinated control of the oil pump flow rate and the piston cooling spray hook flow rate, ensuring lubrication and cooling functions are met under high loads, while reducing oil flow rate and decreasing the driving power of the oil pump under low loads.
