Airbus prepares for its first megawatt-class hydrogen fuel-cell engine flight-test demonstrator

A brand-new, zero-emission aeroplane that will be in service by 2035 could use an architecture of hydrogen-powered fuel cells with cryogenic storage. In less than four years, Airbus is already on schedule to design, construct, and demonstrate such a megawatt-class propulsion system.

While these concepts explore various size categories, aerodynamic layouts and propulsion system architectures, they all have one thing in common: they are hydrogen-fuelled. Three of them have engines which use hydrogen combustion to drive their gas turbines – similar to the way that turbofans and turboprops burn kerosene today, but without the latter’s CO2 and particulate emissions.

Meanwhile, a fourth ZEROe concept aircraft, representing a high-wing 100-seat regional airliner, features six eight-bladed propellers attached to engine pods – a configuration recently patented by Airbus. While outwardly resembling turboprop powerplants, these pods actually contain hydrogen fuel cells which produce electricity as the result of an electro-chemical reaction to power electric motors. It is in this context that Airbus has been conducting feasibility studies and laboratory tests to realise a fully working megawatt-class fuel-cell engine and demonstrator which could be tested in flight by the middle of this decade – around 2026.

For this proof-of-concept demonstrator, liquid hydrogen from the cryogenic tank is converted into a gaseous state. It is then distributed to the fuel cell via supply lines running from the tank and through an external ‘stub’ aerodynamic and load-bearing support structure to the engine pylon interface.

The overall concept which the teams settled on was to make the minimum amount of structural modification inside the A380. just reinforcing two frames of the fuselage and then fitting this stub externally. Then fitting a specially adapted pylon to attach the structure of the pod onto this stub. Overall it will be able to support high sustained static and dynamic loads.

Pakistan’s Ambitious Plan to Acquire and Produce Chinese FC-31 Stealth Fighter

Pakistan’s Ambitious Plan to Acquire and Produce Chinese FC-31 Stealth Fighter

Pakistan is embarking on an ambitious endeavor to bolster its air defense capabilities with the acquisition and potential local production of the Chinese FC-31 stealth fighter jet.

Talks are reportedly underway between the Pakistan Air Force (PAF) and the Shenyang Aircraft Corporation, the developer of the FC-31, signaling a significant leap forward for Pakistan’s military aviation prowess.

The FC-31, a mid-sized, twin-engine fifth-generation fighter, promises advanced air combat capabilities, including stealth technology that surpasses anything currently in the PAF‘s fleet. With plans to retire the JF-17 production line by 2030, the FC-31 could emerge as the new flagship aircraft, offering unmatched performance and versatility.

Experts speculate that Pakistan’s interest in the FC-31 could also signal broader implications for the international market. As China develops both land and carrier versions of the FC-31, analysts foresee it becoming a cost-effective alternative to pricier options like the F-35, potentially challenging the dominance of the US aerospace industry and reshaping global strategic rivalries.

Adding complexity to the deal is China’s push for the WS-13 engine, previously rejected for the JF-17 but now under consideration for both the FC-31 and future JF-17 variants. Engine standardization could streamline logistical and maintenance processes for the PAF, further enhancing the appeal of the FC-31.

While negotiations continue, the success of the FC-31 acquisition and local production hinges on several factors, including the outcome of the WS-13 engine discussions. Pakistan’s pursuit of the FC-31 comes amidst its eagerness to replace its aging fleet, with previous attempts to upgrade its F-16s by the United States due to geopolitical pressures.

Amidst these developments, Pakistan previous interest in the Turkish-made Kaan fifth-generation fighter underscores its eagerness to replace its aging fleet. Despite previous attempts to secure upgrades for its F-16s from the United States, Pakistan’s quest for advanced aerial capabilities has led it to explore alternative avenues, with the FC-31 emerging as a promising contender in its pursuit of air superiority.

Airbus presents new Wingman concept at ILA Berlin Airshow

Airbus presents new Wingman concept at ILA Berlin Airshow

At the prestigious ILA aerospace trade show in Berlin, Airbus Defence and Space made waves by introducing its pioneering Wingman concept, marking a significant leap forward in military aviation technology.

Teaming up with Helsing, Europe’s leading defense AI and software company, Airbus showcased a framework cooperation agreement aimed at revolutionizing the realm of artificial intelligence (AI) in defense.

Airbus Wingman

The Wingman concept represents a paradigm shift in aerial warfare, introducing unmanned platforms equipped with advanced AI capabilities to augment the capabilities of manned combat aircraft. Pilots in command aircraft such as the Eurofighter command these autonomous drones, positioning them to undertake high-risk mission tasks that would traditionally pose a significant threat to manned-only aircraft.

Central to the Wingman concept is Manned-Unmanned Teaming, wherein manned aircraft serve as “command fighters,” retaining ultimate control over mission decisions while delegating tactical tasks to unmanned systems. This synergistic collaboration promises to enhance mission flexibility, increase combat mass, and minimize risk exposure for pilots, thereby bolstering overall operational effectiveness.

The capabilities of the Wingman extend across a diverse spectrum of mission profiles, ranging from reconnaissance and target jamming to precision strikes against both ground and aerial targets. Equipped with advanced sensors, connectivity solutions, and a diverse array of armaments, the Wingman stands poised to redefine the operational landscape of modern air forces.

While the Wingman model showcased at ILA Berlin represents the pinnacle of current technological innovation, it also serves as a catalyst for future design iterations. As with any pioneering concept, refinement and evolution are inevitable, with each generation of the Wingman poised to push the boundaries of aerial warfare even further.

MQ-28 Ghost Bat

Boeing introduced the MQ-28 Ghost Bat, an unmanned combat aerial vehicle (UCAV), which made its maiden flight in February 2021. Developed by Boeing Australia, the MQ-28 leverages artificial intelligence to serve as a force multiplier for manned fighter jets.

The Ghost Bat is engineered to operate in tandem with existing military aircraft, enhancing and extending the capabilities of airborne missions. This cost-effective UCAV is designed to work as an intelligent teammate, complementing and amplifying the effectiveness of manned operations in various mission profiles.

The United States Air Force (USAF) has unveiled the first photographs of the Northrop Grumman B-21 Raider bomber in flight.

These images were captured during test flights conducted by the B-21 Combined Test Force at Edwards Air Force Base, marking a significant milestone in the development of this sixth-generation aircraft.

Currently undergoing flight tests in California, the B-21 Raider represents the next generation of stealth bombers. With an estimated cost of around $700 million per aircraft, the B-21 Raider is poised to become a crucial component of the USAF’s arsenal for conventional Long Range Strike missions.

According to Air Force briefings, the B-21 Raider will form part of a comprehensive family of systems, encompassing Intelligence, Surveillance, and Reconnaissance capabilities, electronic warfare, communication systems, and more. Notably, the bomber will be nuclear-capable and adaptable for both manned and unmanned operations.

It boasts the flexibility to deploy a wide array of stand-off and direct-attack munitions, ensuring versatility in various combat scenarios. One of the B-21’s distinguishing features is its extensive integration of digital technology, as highlighted in discussions held during a Senate Armed Services Committee hearing.

Designed with an open systems architecture, the B-21 Raider is built to swiftly incorporate emerging technologies, ensuring its effectiveness against evolving threats over time. The B-21 Raider is slated to replace the aging B-1 Lancer and B-2 Spirit bombers, bolstering US national security objectives and providing reassurance to allies and partners worldwide.
