【文/观察者网 熊超然】近日，在加拿大蒙特利尔参加国际民航组织（ICAO）第42届大会期间，尼日利 亚民航局局长克里斯·奥纳·纳乔莫（Chris Ona Najomo）告诉路透社，随着尼日利亚航空公司不断接收 更多飞机以扩充机队，以及尼中关系不断提升，尼日利亚民航局正在考虑为中国国产大飞机C919进行 适航认证。 路透社当地时间9月28日报道了这一消息，纳乔莫表示，尼日利亚民航局正在考虑为C919启动长达数月 的适航认证程序，以便该机型能在国内航线上运行。不过，他也提到，C919目前还没有得到西方监管 机构的认证验证。"我们正在研究这款飞机的认证问题。首先，这是我们必须着手的地方。" 尼日利亚航空公司NG Eagle（成立于2023年5月）首席执行官阿卜杜拉伊·艾哈迈德（Abdullahi Ahmed） 表示，该公司有意扩充目前仅有三架飞机的机队，并称如果中国商飞的客机获得适航认证且附带维修与 培训支持，他会予以考虑。 作为联合国专门机构，ICAO每三年举行一次大会。早在2022年10月，在C919获中国民用航空局颁发的 型号合格证后，尼日利亚航空部长就曾在参加当年的ICAO大会时透露，该国将考虑购买C919 ...

作为飞机的"心脏"，航空发动机的重要性不言而喻。但是，要研发一款航空发动机并实现批量服役绝非易事，必须确保其数万个零部件在各类工 况下尤其是在极端环境中稳定、安全、高效地协同工作。这对跨学科技术融合、材料和制造工艺精度、系统集成与控制、测试和适航认证均提出 了极为严苛的要求。 哪怕是航空制造技术领先世界的美国，研制一款航空发动机都免不了经历漫长周期——F135是F35隐身战斗机的发动机。F135从立项（1996年）到 交付第一台量产型F135（2009年）历经13年，但早期的量产型F135依然出现较多故障，直到2015年之后，F135的状态才逐渐稳定下来。因此，航 空发动机被誉为"工业皇冠上的明珠"。 长期以来，航空发动机几乎是欧美的绝对优势项目。相比之下，连日本和韩国这样的工业强国都缺乏先进航空发动机的生产能力，必须大批量进 口军用和民用航空发动机，印度、伊朗和东盟的相关技术储备更是几乎为零。那么，中国的航空发动机技术处于何种水平？我们可以从刚刚结束 不久的九三阅兵中寻找答案。 空中护旗梯队由直10武装直升机、直19武装直升机、直20通用直升机和直8L运输直升机组成。其中，直10搭载"涡轴9"（又名"玉龙" ...

Core Viewpoint - The eVTOL industry is experiencing significant progress in airworthiness certification, with companies like Xiaopeng Huitian and Muyu Tian Aviation making strides in obtaining necessary certifications for their aircraft models [1][3]. Certification Progress - Xiaopeng Huitian's "Land Carrier" flying vehicle (X3-F) had its production license application accepted on May 9, 2023, while Muyu Tian Aviation's AT1300 model's type certificate application was accepted on April 30, 2023 [1]. - The eVTOL aircraft must obtain three key certifications: Type Certificate (TC), Production Certificate (PC), and Airworthiness Certificate (AC) to be legally operated [2]. Industry Insights - The TC is considered the most challenging certification, typically taking 2-3 years to obtain, while the PC and AC are less difficult [3]. - Currently, only two companies, EHang and Fengfei Aviation, have successfully obtained TC, with EHang's EH216-S taking nearly three years for the process [3][4]. Commercial Operations - EHang and Fengfei Aviation have both obtained their PC after receiving TC, with EHang being the only company to hold all four certifications (AC, TC, PC, OC) in China [4]. - The first operational certificate (OC) was issued to EHang's subsidiary and a joint venture, allowing for low-altitude flight services, primarily for sightseeing and experience flights [5][6]. Future Outlook - The issuance of the OC marks a significant step towards the commercialization of low-altitude passenger services and urban air mobility [6]. - EHang plans to expand its operations to include urban commuting and eventually achieve fully autonomous low-altitude transportation services [6].

Core Viewpoint - Despite facing challenges such as insufficient capacity and potential supply chain disruptions due to trade tensions, China Commercial Aircraft Corporation (COMAC) is accelerating the internationalization of its products, with recent successes in the overseas market [2][3]. Group 1: C909 Aircraft Developments - The C909, a regional jet developed by COMAC, has made significant strides in international operations, with Chengdu Airlines wet leasing two C909 aircraft to VietJet Air in April, marking the entry of Chinese commercial aircraft into Vietnam [3][4]. - The C909, originally named ARJ21, has a range of 2,225 to 3,700 kilometers and is designed to accommodate 78 to 90 passengers, targeting short-haul regional routes [3]. - As of March 2025, nearly 300 orders for the C909 have been placed, with 162 aircraft delivered, operating 645 routes and serving 158 cities, transporting over 20 million passengers [3]. Group 2: International Expansion and Partnerships - VietJet Air, Vietnam's first private airline, aims to enhance its fleet capacity and regional route network through the wet lease of C909 aircraft, contributing to the growth of the Vietnamese aviation market [4]. - The C909 has been adopted by three foreign airlines in Southeast Asia, including TransNusa in Indonesia and Lao Airlines, which recently received its first C909 aircraft [5]. - The C909 has facilitated the opening of 15 routes in Southeast Asia, transporting over 250,000 passengers [5]. Group 3: C919 Aircraft and Future Prospects - The C919, another key product from COMAC, faces greater challenges in entering the international market compared to the C909, but there are signs of increasing interest from foreign airlines [6][7]. - COMAC is actively promoting the C919 through international exhibitions and demonstrations, with plans for further exposure in Southeast Asia [8]. - The C919 has received domestic certification and is expected to undergo further evaluations for international certifications, with significant orders already placed [9]. Group 4: Strategic Initiatives and Support - COMAC is establishing an Asia-Pacific office to enhance market services and technical exchanges, aiming to build relationships with international airlines and suppliers [11]. - The company is also collaborating with financial institutions to support the internationalization of its aircraft, with a focus on increasing production capacity to meet demand [10][12]. - Plans are in place to increase the annual production capacity of the C919 from 30 to 50 aircraft by 2025, with a new assembly facility under construction in Shanghai [11].
