Rolls-Royce reaches new milestone building world’s largest aero-engine
Rolls-Royce reaches a new milestone as the world’s largest aero-engine build start : Rolls-Royce has officially started building the world’s largest aero-engine, UltraFan®, which will help redefine sustainable air travel for decades to come.
Work on the first module is underway at our dedicated DemoWorks facility in Derby, UK, and the demonstrator engine, which has a fan diameter of 140 inches, will be completed by the end of the year.
The engine is the basis for a potential new family of UltraFan engines able to power both narrowbody and widebody aircraft and deliver a 25% fuel efficiency improvement compared with the first generation of Trent engine. Performance improvement is crucial to achieving aviation sustainability.
100% Sustainable Aviation Fuel
Gas turbines will continue to be the bedrock of long-haul aviation for many years, and UltraFan’s efficiency will help improve the economics of an industry transition to more sustainable fuels, which are likely to be more expensive in the short term than traditional jet fuel. The first test run of the engine will be conducted on 100% Sustainable Aviation Fuel.

As the engine build starts, other key parts are already coming together for delivery to Derby. Work is underway on UltraFan’s carbon titanium fan system in Bristol, UK, and its 50MW Power Gearbox, which is powerful enough to run 500 family cars, in Dahlewitz, Germany.
UltraFan is part of Rolls-Royce’s IntelligentEngine vision – for example, each fan blade has a digital twin that stores real-life test data, allowing engineers to predict in-service performance.
When on test at Rolls-Royce’s new £90m Testbed 80 facility, data can be taken from more than 10,000 parameters, detecting the tiniest of vibrations at a rate of up to 200,000 samples per second. Data that helps us understand our engines and further improve them.
Key engineering features of the engine include:
- A new, proven, Advanced 3 core architecture, combined with our ALECSys lean burn combustion system, delivers maximum fuel burn efficiency and low emissions.
- Carbon titanium fan blades and a composite casing that reduce weight by up to 1,500lb per aircraft.
- Advanced ceramic matrix composite (CMC) components that operate more effectively in high-pressure turbine temperatures.
- A geared design that delivers efficient power for the high-thrust, high bypass ratio engines of the future.

FAA rolling out new technology at four US airports
The Federal Aviation Administration (FAA) is set to debut cutting-edge airfield surveillance systems at four prominent airports across the United States.
Austin-Bergstrom, Indianapolis, Nashville, and Dallas Love Field will spearhead the implementation of the Surface Awareness Initiative (SAI) by July 2024, marking a significant stride in runway safety enhancement efforts.
SAI revolutionizes air traffic controllers’ situational awareness by leveraging Automatic Dependent Surveillance – Broadcast (ADS-B) data. Through this innovative technology, controllers gain real-time and precise depictions of aircraft and vehicles navigating the entire airfield, irrespective of weather conditions.
Icons representing aircraft and ADS-B-equipped vehicles will populate an airport map, offering comprehensive coverage of runways, taxiways, hold ramps, and other critical areas.
This initiative is a pivotal component of the FAA’s accelerated surface safety portfolio, complementing other vital tools like Approach Runway Verification (ARV) and the Runway Incursion Device (RID). The proactive deployment of these technologies underscores the FAA’s unwavering commitment to fortifying runway safety and averting potentially hazardous incidents.
Beyond technological advancements, the FAA is taking multifaceted measures to bolster safety across the national airspace system. Initiatives include aggressive air traffic controller recruitment drives, enhancements to the Air Traffic-Collegiate Training Initiative, and the deployment of upgraded tower simulator systems in numerous facilities nationwide by the end of 2025.
Additionally, the FAA is fostering collaborative efforts through regular runway safety action team meetings and investing substantially in runway lighting and surface improvements at airports of varying sizes.

Boeing says 787 Dreamliner aircraft is safe
Boeing is standing firm on the safety and durability of its 787 Dreamliner aircraft despite mounting criticism and whistleblower allegations.
In response to concerns raised by whistleblowers and ahead of a congressional hearing, the aviation giant emphasized its rigorous testing protocols and asserted confidence in the integrity of its planes.
During a media briefing accompanied by a PowerPoint presentation, boeing aircraft
reiterated its confidence in the safety of both the 787 and 777 aircraft models. Senior engineers showcased extensive testing procedures aimed at refuting claims that approximately 1,400 Boeing planes may be afflicted by significant safety issues. The company addressed specific allegations, including concerns about gaps in manufacturing processes that could lead to premature fatigue failure over time.
The upcoming Senate hearing is expected to feature testimony from Boeing engineer Sam Salehpour, who has publicly criticized boeing airplanes safety practices and alleged retaliation for speaking out. Salehpour’s claims, currently under investigation by the FAA, include allegations of workers resorting to extreme measures during assembly, such as “jumping on pieces of the airplane” to align them.
Boeing officials stressed that thorough inspections of nearly 700 in-service Dreamliner jets revealed zero airframe fatigue findings, even after six and twelve years of heavy maintenance inspections. These results have been shared with the FAA, according to Boeing’s chief engineer, Steve Chisholm. He emphasized that the materials used in the construction of the 787 were specifically chosen for their resistance to fatigue and corrosion.
In response to Salehpour’s accusations of shortcuts in assembly processes, boeing planes
acknowledged instances where shims were not of the proper size and where areas did not meet skin-flatness specifications. However, the company dismissed claims of excessive force during assembly, stating that such practices were not part of their standard procedures.
