Is Airbus planning to modify the A321XLR’s belly fuel storage?

This is how Airbus tests the new A321XLR flight with passengers traveling nonstop.

The Airbus A321XLR is one of the most long-range commercial aircraft in the narrow-body class, having recently demonstrated a nonstop 13-hour flight. The Authority, on the other hand, is unsatisfied with certain elements of the aircraft, which are likely to make the aircraft unsafe for some reason.

The first 13-hour test flight of the A321XLR was successfully accomplished.

The FAA previously suggested that essential adjustments be made to the aircraft’s over-the-rear fuel storage during any crash landing since this might result in the risk of catching fire and unsafe over-crash landing.

EASA has now expressed its support for the FAA regulation and requested the required changes for flight safety.

According to the EASA document, which was released on D, “EASA identified the need to prescribe special detailed technical specifications (dubbed Special Conditions) to ensure adequate occupant protection against the risks of external fire and burn-through, fuel vapor ignition, and fuel tank explosion, as well as to ensure crashworthiness of this fuel tank so that no fuel is released in sufficient quantities to start a serious fire in an otherwise survivable crash event.”


Since Boeing expressed concerns to regulators, the design of the integrated tank with a capacity of 19.200 litres has been the focus of attention. If the tank was penetrated by some portion, the close closeness to the landing gear could constitute a hazard during a hard landing. Furthermore, with passengers seated directly on top of the tank, cold fuel could have an impact on cabin comfort. Because the fuel tank and passenger seats are in the same location, there is less time for evacuation during the crash.

The gasoline tank should be located in a specific aircraft fuselage location “that is not likely to collapse or rupture in a survivable crash event beyond the appropriate existing emergency landing conditions,” according to the agency.

Aurora Flight Sciences Unveils Innovative X-Plane Design

Aurora Flight Sciences Unveils Innovative X-Plane Design

Aurora Flight Sciences, a Boeing company, has recently completed the conceptual design review for a groundbreaking high-speed, vertical lift X-plane.

This aircraft, part of the Defense Advanced Research Projects Agency (DARPA) program called Speed and Runway Independent Technologies (SPRINT), aims to demonstrate key technologies and integrated concepts that combine high speed with runway independence.

Aurora’s design features a low-drag, fan-in-wing demonstrator integrated into a blended wing body platform. This innovative approach merges the agility of vertical take-off and landing (VTOL) with exceptional speed capabilities.

The team is focused on ensuring the program’s success by setting the stage for successful flight demonstrations, showcasing a transformative capability for air mobility and Special Operations Forces (SOF) missions.

New renderings of the fan-in-wing (FIW) demonstrator show three lift fans, a more refined composite exterior, and an uncrewed cockpit. The decision to use three lift fans simplifies the demonstrator, streamlining its path to flight testing. This FIW technology can be scaled to incorporate four or more lift fans to meet future aircraft requirements, potentially leading to a new family of systems.

Additionally, while the current demonstrator is uncrewed to facilitate testing and reduce risk, the FIW technology is fully adaptable to crewed aircraft. Aurora’s concept is designed to meet or exceed DARPA’s challenging program objectives. The blended wing body platform is capable of a 450-knot cruise speed, and the embedded lift fans with integrated covers enable a smooth transition from vertical to horizontal flight.

COMAC has initiated work on the C939, a new wide-body airliner. While design concepts have been formulated, it will still take several years before a prototype materializes, according to reports from the South China Morning Post, citing anonymous sources.

Initially intended to be a joint venture with Russia, plans were halted due to Russia’s decision to safeguard its copyrights and technological advancements within its borders. Consequently, collaboration between China and Russia on aircraft development was discontinued. Sources suggest that China is vigorously pursuing new avenues for the independent development of its own wide-body aircraft, crucial for accommodating larger passenger capacities and extended flight ranges.

Comac C939 competes with Boeing 777 and A350

Information regarding the program remains limited. COMAC has refrained from commenting on the development of the new aircraft type, stating that official announcements will be made in due course. Nevertheless, the C939 could potentially accommodate up to 390 passengers, positioning it to compete with the largest Boeing 777 and Airbus A350 aircraft.

In addition to the prospective C939, COMAC is already advancing with the development of another widebody aircraft, known as the C929. This aircraft is poised to rival the Boeing 787 and Airbus A330, boasting 280 seats and a range approaching 6,500 nautical miles.

Since obtaining certification in late 2022, the COMAC C919 has been operational, accumulating nearly 1,000 firm orders, predominantly from Chinese-owned airlines and leasing companies.

With multiple widebody aircraft in the pipeline, COMAC stands to achieve parity with the two leading international aircraft manufacturers. Boeing, with its 777 and 787 models, and Airbus, with the A330neo and A350, both have a comparable range of offerings. However, Boeing’s aircraft are encountering delays and production challenges despite substantial orders, while the A350 is performing commendably, though the A330neo’s order intake has not met initial projections.

How much does C919 cost?

China is under pressure to fulfill the current orders for the C919 aircraft, prompting plans to expand production facilities across various regions within the country. The aim is to ramp up production capacity for C919 planes to 150 aircraft annually over the next five years. The latest reports indicate that the C919 is priced around $99 million, comparable to the price of Boeing 737 Max and Airbus A320 aircraft, with expectations for further price reductions in the future.

While the C919 has yet to be certified in major aviation markets outside of China, only four have been delivered thus far. In the long term, COMAC’s widebody aircraft will vie for global competitiveness. One potential benefit of COMAC aircraft could be in reducing China’s reliance on Western aircraft manufacturers. However, this shift won’t happen immediately; the current delivery rate of four aircraft in nearly 18 months is not sustainable, and both Airbus and Boeing have established manufacturing facilities in China to cater to its sizable market.

Nevertheless, assuming COMAC addresses the issues impeding deliveries, there’s a plausible scenario where the manufacturer assumes a significant role, particularly as China’s aviation market continues to expand.

As the C939 progresses through its development stages, more details are expected to emerge. Comparisons between official specifications of the C929 and C939 will be noteworthy, as will the initial orders for each aircraft type. However, it’s anticipated that neither will undergo test flights or enter into service for several years.
