To assess the HET-450 high-power Hall thruster aiming at SSPS, a Particle in Cell (PIC) based model is built to simulate the interplay of discharge voltage, gas flow rate et al with the thruster discharge performance. To test the PIC simulation results, a high-power Hall thruster test platform is constructed for thruster characterization. By comprehensive simulation, the scope of electrical and mechanical operation is determined to match the thruster configuration. From simulation, the atomic density, electrical field and electron temperature distributions inside the thruster discharge channel are clarified and therefore the ionization and acceleration dynamics of thrust formation is discussed. In addition, the model is able to figure out the discharge current and thrust output for any operation conditions and therefore measurement of the thruster performance is carried out using the test platform to verify the model reliability. The results of discharge current and thrust obtained from simulation and experiment agree well to each other. The simulation results show that the discharge voltage varying from 300 V to 500 V raises the ionization efficiency and increases the discharge current, thrust and anode efficiency. However, for the discharge voltage over 500 V, the thruster walls are overheated, due to high ion flux on the thruster walls and resultant high ion recombination rate. Once the wall overheating occurred, the working fluid utilization and therefore the anode efficiency decreased. Thruster performance optimization based on simulation gives that the thruster can output 2.1 N of thrust and as high as 60% of anode efficiency using 500V of discharge voltage and 80mg/s of flow rate, which indicates that the HET-450 design scheme works well.</div></div>","PeriodicalId":101177,"journal":{"name":"Space Solar Power and Wireless Transmission","volume":"3 1","pages":"Pages 10-18"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147553319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laser Wireless Power Transfer (LWPT) technology, with its advantages including long transmission distances and high power, presents a promising solution for energy supplementation. Nevertheless, in flight environments, LWPT systems encounter multiple challenges—spillover losses arising from beam spot-to-photovoltaic (PV) array mismatch due to varying transmission distances and electric mismatch losses caused by non-uniform irradiation induced by changes in UAV attitude. This paper develops a “transmitter-beam distribution-PV array” coupled model to simulate the optical-thermal-electrical multi-physics coupling characteristics of the PV array, considering varying transmission distances, pointing errors, and attitudes. Furthermore, a zoom system based on a dynamic beam waist adjustment method is proposed to optimize the beam waist radius for varying transmission distances, thereby effectively reducing spillover loss. Results indicate that the zoom system improves cut-off efficiency and extends the effective power transmission range compared to a fixed-focus system. While the received power loss from normal deviation follows the expected geometric cosine law, the study reveals that the radial deviation angle significantly exacerbates electrical mismatch. When the radial deviation angle reaches a maximum of 45°, the mismatch loss rate attains 32%, leading to a 13.74% decrease in output power due to non-uniform sub-module activation. Under pointing error conditions (20 mm, 45°), system efficiency decreased by 48%. The findings of this study are valuable for achieving efficient power transfer for UAV-based LWPT systems.</div></div>","PeriodicalId":101177,"journal":{"name":"Space Solar Power and Wireless Transmission","volume":"3 1","pages":"Pages 50-65"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147553315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
