A study from Shandong Technology and Business University uses game theory to explore rural distributed photovoltaic (PV) development from a prosumer lens. It identifies village-PV enterprise collaboration as key to scaling adoption, highlights the need to balance self-consumption and grid capacity to avoid curtailment, and provides targeted policy guidance for rural energy transitions.

A research team from the Beijing Institute of Technology (BIT) and Yinhe Hangtian has achieved a major advance in orbit mechanics by developing an analytical method capable of directly predicting spacecraft trajectories under third-body gravitational perturbations. This work, recently published in the Chinese Journal of Aeronautics, resolves a long-standing challenge in celestial dynamics and provides a new theoretical tool for deep-space exploration and autonomous spacecraft control.

The wide-speed-range vehicles have attracted significant attention due to the exceptional performance in autonomous aerospace operations. In a recent innovative study published in the Chinese Journal of Aeronautics, a double swept waverider employing novel vortex-wave coupling technology has addressed the fundamental compromise between high-speed shockwave management and low-speed vortex lift utilization. By integrating basic flow field design with an Improved Multi-Objective Cuckoo Search algorithm, this configuration achieves breakthrough wide-speed-range performance, laying a critical foundation for the development of horizontal take-off and landing aerospace vehicles.

The notion of employing detonation to enhance aerospace propulsion systems has been explored for several decades. In a recent breakthrough, a novel detonation engine known as the Ram-Rotor Detonation Engine has emerged. This innovative engine integrates the processes of propellant compression, detonation combustion, and expansion within a single rotor, enabling it to markedly enhance propulsion efficiency across a broad range of flight Mach numbers.

A key challenge in parallel adaptive Cartesian grid generation is significant computational load imbalance during k‑d tree searches. A new Dynamic Partition Weight approach, published in the Chinese Journal of Aeronautics (https://doi.org/10.1016/j.cja.2025.103921), solves this by predicting each cell’s required k‑d tree iterations and performing intelligent load rebalancing. This method enables the generation of billion‑cell grids for complex aircraft models in less than a minute, offering a breakthrough for high‑fidelity CFD simulations.
