the rotating engine components subject to coriolis and centrifugal forces exhibit distinctive ice accretion characteristics when an aircraft operates under supercooled large droplet conditions. this study establishes the mathematical model of the ice accretion on rotating components of engine entry and considers the dynamic characteristics of terminal velocity， deformation， breakup， splash， and rebound of supercooled large droplets. the multiple reference frame method is employed to deal with the fluid flow and heat transfer under the rotating condition. a three-dimensional numerical simulation is conducted to investigate the droplet impingement and ice accretion characteristics of entry components， including the inlet lip， spinner， and fan blades. the simulation results at rotational speeds of 0， 2 000， and 4 100 r/min show that the ice accretion on the inlet lip moves towards the outer surface of the inlet lip from the inner surface as the rotational speed increases. moreover， the ice accretion on the blades is mainly concentrated at the blade root， and the ice accumulation decreases with the increase of rotational speed. the ice thickness on the inlet lip and spinner increases with increased rotational speed. the maximum ice thickness on the inlet lip and spinner under the rotational speed of 4 100 r/min increases by 0.27 and 2.46 times， respectively， compared to the stationary condition. this work can serve as a reference for developing subsequent anti/de-icing technology. ,in application scenarios such as smart cities， a single wireless communication technology cannot cover complex network environments， while different communication technologies cannot communicate with each other， making it impossible to take full advantage of different wireless communication technologies. therefore， we design a device that can communicate with multiple wireless communication nodes， which is called wireless heterogeneous communication modules （whcm）. whcm is used as a hub to build a communication heterogeneous mesh network （chmn）. chmn consists of nodes with multiple wireless communication protocols. we propose an ad hoc on-demand multi-path distance vector （aomdv） routing protocol based on chmn networks， named ch-aomdv. ch-aomdv is able to identify different types of communication protocols during the route initiation and path establishment process. it can also identify the communication distance， data transmission rate， energy and the load capacity of each node in chmn. simulations with ns-2 show that the performance of the chmn is better than that of the traditional network when the distribution density between nodes is higher in terms of packet delivery rate， average end-to-end delay， throughput rate and routing overhead. this work proposes a new method of implementing chmn and the corresponding routing protocol ch-aomdv. the proposed protocol is superior to the other three protocols， improves network lifecycle， throughput and packet delivery rate， and reduces node overhead and average end-to-end delay. the protocol is useful for chmn.
