【巴黎航展現場報導】位於法國的創新飛機製造商 VoltAero 在巴黎航展開幕前，正式公開其電動-混合動力區域型飛機 Cassio 330 的量產構型，標誌該機型邁入空氣適航認證與商業化製造的重要里程碑。
[Le Bourget | June 17, 2025] – France-based VoltAero has revealed the finalized production version of its Cassio 330 hybrid-electric aircraft, underscoring progress toward EASA certification and commercial deployment for sustainable regional aviation.

此次構型優化是VoltAero與歐洲航空安全局（EASA）密切合作的成果，符合其最新的CS-23標準，並降低整體設計的認證複雜度，落實實用可行的技術應用原則。
The updated configuration reflects extensive collaboration with the European Union Aviation Safety Agency (EASA), resulting in a simplified path to certification under the latest CS-23 rules.

「我們始終堅持務實路線，採用當下就能量產、可維修、適配現有機場的混合動力技術，讓區域航空更安靜、更乾淨。」VoltAero執行長Jean Botti表示。
“Our strategy remains clear: leveraging mature hybrid-electric technologies for aircraft that fit existing airport infrastructure and enable sustainable operations today,” said VoltAero CEO and CTO Jean Botti.

創新轉型：從並聯轉向序列式混合架構

量產版Cassio 330採用「序列式混合動力架構（series-hybrid architecture）」，兩具位於後機身的Safran ENGINeUS™智能電動馬達驅動螺旋槳，並由內部熱能引擎在巡航階段為電池充電。起飛與初段飛行階段完全採電力驅動，兼顧低噪音與零排放。
The production variant features a series-hybrid system with twin Safran ENGINeUS™ electric motors mounted aft, providing propulsion during taxi, takeoff, and climb, while a thermal engine recharges the batteries during cruise.

這與原先的並聯設計（引擎與馬達共驅單一螺旋槳）不同，大幅提升模組化與安全冗餘設計彈性。
This marks a shift from the earlier parallel-hybrid setup, improving operational safety, maintainability, and system modularity.

安全架構與雙冗餘系統設計

新架構將Cassio 330納入多引擎類別，使其具備商業營運潛力。除了雙電動馬達外，每具ENGINeUS™均具備雙繞組獨立供電設計（HEI功能），電池模組亦採雙獨立串聯設計，達到全面冗餘要求。
The multi-motor configuration classifies the aircraft as a twin-engine model under EASA, enabling commercial certification. Dual stator windings and redundant battery strings enhance safety and operational reliability.

T尾設計、新構型與乘客友善介面

在外觀上，新版Cassio 330改採T尾設計，取代原有雙尾樑架構，進一步減少螺旋槳失效造成的結構風險。機艙則維持原有6人座布局（1駕駛+5乘客），可模組化支援貨運、醫療轉運與公務航線用途。
Visually, the new T-tail replaces the earlier twin-boom design, reducing potential blade damage risks. Inside, the modular six-seat cabin remains, suited for passenger, cargo, medevac, and PSO route operations.

機艙前方配置大型側門，方便行動不便乘客上下機，特別針對偏鄉機場的公共服務航線所設計。
A forward cabin access door improves accessibility, especially on Public Service Obligation (PSO) routes to remote airports.

工業量產基地：擴張目標鎖定150架／年產能

Cassio 330將於VoltAero位於法國 Nouvelle-Aquitaine 地區 Saint Agnant 的新廠進行量產，該廠年產能規劃為150架，並將作為後續全球生產鏈的核心節點。
Production will take place at VoltAero’s new 2,400-square-meter factory in Saint Agnant, France, which will serve as the main hub for Cassio aircraft output, targeting a 150-aircraft annual rate.

目前，Cassio 330量產版的實體模型已在巴黎航展靜態展示區（Static Display B4）亮相，並同步展出混合電動推進系統的核心模組與飛控架構。
