# 2. Founded 2016: Consolidating Aerospace Teaching and Research

According to the AAE Research Overview page^※, AAE was established in July 2016 with the aim of consolidating and leading the development of aeronautical and aviation engineering in Hong Kong. Since its founding, AAE has quickly become the largest department of its kind in Hong Kong and continues to rank among the top in research expertise.

The timing of AAE's establishment (2016) is worth noting — it falls between PolyU's landmark space achievements (the Chang'e-3 camera pointing system in 2013 and Chang'e-4 in 2019). Consolidating aerospace teaching and research into a standalone department gave PolyU a more concentrated academic vehicle in this strategic field. One clarification: Prof. Yung Kai-leung's instrument development team sits in the Department of Industrial and Systems Engineering (ISE), not in AAE — AAE and ISE are two parallel academic pillars in PolyU's space programme. The former provides the disciplinary home for aircraft and satellite engineering; the latter supplies precision instrument fabrication capabilities. Together they underpin PolyU's overall space research architecture (see aerospace-and-space.md).

Source strength: AAE's Research Overview page confirms the July 2016 founding and its status as the largest department of its kind in Hong Kong.

According to the PolyU Scholars Hub organisation page^※, AAE was originally established under the name "Interdisciplinary Division of Aeronautical and Aviation Engineering" — it first gathered aerospace specialists scattered across departments such as mechanical and electrical engineering under an "interdisciplinary division" structure, and was only later formally elevated to a standalone department. This path of "testing the waters as an interdisciplinary unit before formalising as a department" echoes the approach PolyU has used in recent years — "first establish a PAIR platform/research centre, then decide whether to upgrade it to a standalone department once it matures" (for PAIR's evolution, see pair-interdisciplinary-research.md).

Third-party rankings offer external validation of the department's academic standing. According to an AAE official press release^※, in the 2022 Global Ranking of Academic Subjects (GRAS), PolyU's "Aerospace Engineering" subject was ranked No. 1 in Hong Kong and No. 44 globally (announced 22 July 2022). It should be noted that GRAS is a specialised subject ranking with a different methodology from the better-known QS World University Rankings by Subject — in the QS World University Rankings by Subject 2026, PolyU falls under the broader category "Mechanical, Aeronautical & Manufacturing Engineering", where it ranks No. 53 globally (per QS public data). The two rankings use different statistical methods and are not directly comparable, but both point to AAE's international recognition in aerospace engineering.

The department's current head is Prof. Wen-Hua Chen, whose title, per the AAE website, is Chair Professor of Robotics and Autonomous Systems, serving as Interim Head while concurrently directing the aforementioned Research Centre for Low Altitude Economy — a sign that the department's leadership is closely tied to the emerging research direction of the low-altitude economy.

# 3. Six Research Areas

According to AAE's official materials, the department spans six major research areas, covering nearly the full spectrum of aerospace engineering "from the ground to space":

The six areas each have distinct emphases but interlock tightly: aerodynamics — the study of airflow around aircraft, and the starting point for designing any flying vehicle; structures and materials — determining whether an aircraft can withstand extreme loads without failure; propulsion and combustion — where the power comes from; flight mechanics and control — making the aircraft "obey commands"; satellite communications and navigation — extending the research frontier from the atmosphere into low Earth orbit, of which the 2026 LEO CNAV satellite payload is the flagship product (see leo-comm-nav-satellite-payload-2026.md). Aviation engineering is more applied, focusing on whole-aircraft systems and maintenance engineering. Together, these provide a systematic disciplinary foundation for PolyU's engagement with the nation's space programme.

# 4. Aviation Research Consortium and Advanced Facilities

# 4.1 Aviation Research Consortium

According to the Aviation Research Consortium page^※, AAE hosts an Aviation Research Consortium whose research covers airline operations, air traffic management, airline and airport operations management, air mobility, sustainable air transport systems, aviation safety and reliability, and human factors — directions oriented more towards "air transport and management", reflecting Hong Kong's practical needs as an international aviation hub. This research strand differs from the engineering mainline of "building aircraft/satellites"; it is closer to the day-to-day running of the aviation industry — from airport scheduling to flight safety management — the soft-power capabilities Hong Kong must continually invest in as an international aviation hub.

# 4.2 Advanced Facilities

According to AAE's materials, the department is equipped with a range of advanced experimental facilities, including:

• Supersonic wind tunnels: for high-speed aerodynamic research, used to verify aircraft aerodynamic characteristics under supersonic conditions;
• UAV test systems: supporting the design, test-flying and data collection of unmanned aerial vehicles;
• Materials manufacturing and testing platforms: for validating the strength and durability of aerospace materials.

These "hard-core" facilities ensure AAE's research and teaching go beyond theory into real experimentation and testing — consistent with PolyU's tradition of "learning by doing, application-oriented".

# 4.3 Research Centre for Low Altitude Economy

AAE also hosts the Research Centre for Low Altitude Economy, led by Prof. Wen-Hua Chen, focusing on low-altitude transport infrastructure planning, airspace design and reliable perception technologies for autonomous aircraft. The centre's establishment aligns with Hong Kong's recent policy push for the low-altitude economy (new economic forms using drones, eVTOLs and the like in airspace below 1,000 metres), and is technologically complementary to the LEO CNAV satellite payload that the AAE team is developing for 2026 (see leo-comm-nav-satellite-payload-2026.md) — the former addresses "how to fly", the latter "how to position and communicate".

# 5. Two Emerging Offshoots: RILA for Domestic Large Aircraft, RCUAS for Unmanned Systems

Over the past two years, AAE has added two interdisciplinary research platforms — one connecting to the "large aircraft" industry, the other deepening work on "unmanned systems" frontiers — and, notably, both are headed by the same professor. That itself is a clue worth recording.

# 5.1 COMAC–PolyU Research Institute for Large Aircraft (RILA)

According to a PolyU press release^※, PolyU and the Commercial Aircraft Corporation of China (COMAC) signed a cooperation agreement on 12 November 2024^※ to establish the "COMAC–PolyU Research Institute for Large Aircraft (RILA)". The agreement was signed by PolyU's Vice President (Research and Innovation), Prof. Christopher Chao^※, and COMAC Vice President Shen Bo, witnessed by PolyU President Prof. Teng Jin-guang, Dean of Engineering Prof. Wen Xiao-zhong, and COMAC Chairman He Dongfeng and Vice Chairman Yuan Guohua (per the PolyU press release). The institute aims to "promote the development of the large aircraft industry", focusing on key technical challenges in the development of domestically produced commercial aircraft and frontier new technologies (per the PolyU press release).

According to the RILA website "About Us" page^※, the institute's research scope covers the full lifecycle of large aircraft, with four focus areas:

RILA also undertakes joint research projects, patent applications and academic publications, and provides training for postgraduate students and researchers (per the RILA website). The institute's director is Prof. Chih-Yung Wen — the same person leading the LEO CNAV satellite payload project (see leo-comm-nav-satellite-payload-2026.md). RILA's establishment follows the same model as other "industry-academia research institutes" under PolyU's PAIR interdisciplinary research system (for its evolution, see institutes-and-labs.md), and marks a widening of AAE's industry engagement from "Hong Kong's local aviation operations" to "the nation's large aircraft industrial chain".

# 5.2 Research Centre for Unmanned Autonomous Systems (RCUAS)

According to the RCUAS website^※, the Research Centre for Unmanned Autonomous Systems (RCUAS) coordinates cross-faculty/department unmanned systems research at PolyU and coordinates internal and external collaborations, covering three major system categories: unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs) and unmanned underwater vehicles (UUVs). The centre's research directions include perception and navigation, multi-robot systems, embodied intelligence, large language models and trustworthy AI, and it has extended its research frontier into Space and Humanoid Robotics — exploring the application of intelligent robotic systems in extreme and unstructured environments such as space and disaster zones, including humanoid robots and exoskeleton systems (per the RCUAS website). The centre's director is again Prof. Chih-Yung Wen.

RCUAS's applied research has already translated into concrete industry-academia collaborations. According to PolyU Research and Innovation Office news^※, a PolyU team partnered with Meituan in January 2023 on a project titled "Vision Aided GNSS-RTK Positioning for UAV System in Urban Canyons", led by Dr. Weisong Wen. The project targets a specific pain point: in urban canyons lined with tall buildings, satellite signals are easily blocked, degrading UAV positioning accuracy. The team combined visual positioning with GNSS-RTK (Global Navigation Satellite System — Real-Time Kinematic) to improve the accuracy and reliability of UAV positioning in complex urban areas. Prof. Chih-Yung Wen commented on the project: 「这一项目能有效提升无人机系统在复杂城市峡谷中自主包裹配送的定位精度与可靠性」^※ ("This project can effectively improve the positioning accuracy and reliability of autonomous parcel delivery by UAV systems in complex urban canyons") (per PolyU news). This is a representative case of AAE's UAV research moving from "laboratory testing" to "real-world commercial scenario validation", and ties into the "how to fly" agenda of the Research Centre for Low Altitude Economy discussed in Section 4.

# 6. Talent Development: From Classroom to Hangar, to Space

AAE's undergraduate programme admits through the Aviation Engineering Scheme (e.g. JS3140), which, according to the programme page^※, covers streams such as Aviation Engineering / Air Transport Engineering. The curriculum spans from aerodynamics and propulsion systems to avionics and aircraft maintenance, and graduates are equipped for careers in aircraft maintenance engineering, aircraft component engineering and other aviation fields.

Hong Kong, as an international aviation hub (with major airports, airlines and maintenance bases), has steady demand for aviation engineering talent. AAE's graduates feed directly into this industry need — another instance of "PolyU disciplines answering Hong Kong industry needs".

In recent years, AAE's talent pipeline has extended from "aviation" to "space/low-altitude economy". Per the AAE website, in September 2026 the department will offer two new taught postgraduate programmes for the first time: MSc in Satellite Engineering and MSc in Low Altitude Economy — the former is the first programme of its kind in Hong Kong, covering satellite orbital dynamics and spacecraft system design; the latter focuses on low-altitude vehicle technologies, intelligent navigation and airspace traffic management. Both programmes sit in the same department as the research team behind the LEO CNAV satellite payload, creating a "research-led teaching" loop (see leo-comm-nav-satellite-payload-2026.md for details).

PolyU's Undergraduate Research and Innovation Scheme (URIS) also offers interested undergraduates the chance to join formal research projects under their supervisors; AAE topics in UAVs, composite materials and precision manufacturing are popular URIS directions. This forms a complete talent pipeline from undergraduate classrooms, through postgraduate programmes, to real research projects.

# 7. Placement in PolyU's Space Research Landscape

AAE mutually reinforces PolyU's space achievements and research platforms:

• AAE: the disciplinary home of aerospace (six research areas, wind tunnels, UAVs), directly building the LEO CNAV satellite payload, and hosting two new platforms, RILA and RCUAS (see Section 5 above);
• Precision engineering team (Department of Industrial and Systems Engineering, ISE): leading national deep-space exploration instrumentation (sampling systems, Mars camera — see aerospace-and-space.md);
• PAIR Research Centre for Deep Space Explorations (RCDSE): an interdisciplinary platform (see pair-interdisciplinary-research.md);
• InnoHK Cluster 3 (SEAM): covering sustainability, energy and space technology (see innohk-and-knowledge-transfer.md);
• State Key Laboratory of Ultra-precision Machining Technology: providing micron/nanometre-level precision manufacturing support for space instruments (see state-key-laboratories.md).

In a sentence: from air transport to deep-space exploration, from satellite payloads to the low-altitude economy, and on to domestically produced large aircraft and unmanned systems, PolyU has the department (AAE), the teams, the platforms and the outcomes in "aircraft and space" — a rare, complete aerospace landscape among Hong Kong universities; for the full timeline, see aerospace-program-overview.md.

# 8. Frequently Asked Questions (Q&A)

Q1: Is AAE the same group as PolyU's space instruments team (Prof. Yung's team)?

No. Prof. Yung Kai-leung's deep-space instrumentation team (camera pointing system, lunar surface sampling and encapsulation system, Mars camera) sits in the Department of Industrial and Systems Engineering (ISE), following the "precision instrument fabrication" route; AAE is a standalone department, following the "aircraft/satellite engineering" route. The two are parallel disciplinary pillars in PolyU's space programme. The 2026 LEO CNAV satellite payload is developed in-house by AAE, a separate project from the ISE team's deep-space instruments (for the detailed distinction, see aerospace-and-space.md).

Q2: What is COMAC, and why does PolyU want to cooperate with it?

Commercial Aircraft Corporation of China (COMAC) is the state-level enterprise developing large passenger aircraft in mainland China (such as the C919). The RILA partnership with COMAC, on the one hand, puts AAE's aviation engineering research directly in service of the actual needs of the national large aircraft industry (digital-intelligent manufacturing, predictive maintenance, etc.); on the other, it offers PolyU faculty and students a platform to participate in research and development across the domestic large aircraft's full industrial chain. It is another layer of cooperation, after the deep-space instrumentation collaborations, between PolyU and a state-level aerospace industry organisation.

Q3: What is the difference between the Research Centre for Low Altitude Economy and RCUAS?

Their research scopes overlap but with different emphases: the Research Centre for Low Altitude Economy focuses on low-altitude transport infrastructure planning and airspace design (i.e. "how to fly safely and in an orderly manner" — more policy- and systems-oriented); RCUAS focuses on the core technologies of unmanned systems themselves — perception, navigation, multi-agent coordination (i.e. "how the drone/robot itself is built" — more engineering- and algorithm-oriented). The two are complementary — RCUAS's technical outputs (such as the visual positioning technology from the Meituan project) can support the airspace operation solutions developed by the low-altitude economy centre.

Q4: AAE is ranked No. 1 in Hong Kong — does that mean it is the only department offering aerospace engineering in Hong Kong?

No. The Faculty of Engineering at the Hong Kong University of Science and Technology (HKUST) also offers an undergraduate aerospace engineering programme. AAE's "No. 1 in Hong Kong" is a result from the specific evaluation system of the GRAS subject ranking, reflecting the discipline's relative position under that particular ranking methodology — it does not mean it is the "only" programme on offer. For differences in specific curriculum design, please compare the two universities' official programme pages.
