Airbus remains at the cutting edge of the aviation industry; leading the way in terms of innovation and progress. The desire to continuously improve technology is embedded within the heart of the company, which allows Airbus to constantly deliver proven new technological advancements that push the boundaries of what is possible. This means that all stakeholders can benefit from proven high quality improvements in design, manufacturing, operations and maintenance. Such advances include the introduction of full fly-by-wire flight controls technology, employing modern materials in its airframes, and developing cockpit designs that improve pilot workload and efficiency.
A350 XWB going that extra mile
The A350 XWB flight deck features maximum commonality with Airbus’ comprehensive market-leading product line. In the A350 XWB’s ‘front office’, its flight deck has been updated – built around an arrangement of six identical, interchangeable large displays. This is a continuation of Airbus’ philosophy for creating ergonomic flight decks that combine commonality and innovation.
Providing maximum commonality with Airbus’ other jetliner families, this flight deck configuration is fully aligned with the company’s unique Cross Crew Qualification concept – which gives pilots the possibility of transitioning from one Airbus aircraft type using digital fly-by-wire controls to another via difference training instead of full type rating training. In addition, the concept allows for full interchangeability of the A350 XWB flight deck’s large displays in cases of failure.
With its state-of-the-art Rolls-Royce Trent XWB engines, the A350 XWB is able to outperform competitors in terms of fuel economy, emissions and overall efficiency. These lightweight, three-shaft powerplants – the latest in Rolls-Royce’s Trent family – is produced using advanced manufacturing techniques for a lighter, more capable and highly efficient engine. It features high-tech materials, coatings, engine architecture, and cooling technologies – including a third-generation low-speed fan and contra-rotation operation.
With a single engine type for the complete A350 XWB jetliner family, the Trent XWB provides commonality across the product line – at thrust ratings of up to 97,000 lb. Additional benefits include module weight savings of 15 per cent, along with aerodynamic efficiency improvements through the use of compressor blisk (bladed disk) technology.
Revolutionary digital mock-up
The A350 XWB’s revolutionary digital mock-up is a ‘gamechanger’. Airbus has created a bridge between the virtual and real worlds with its A350 XWB digital mock-up, which provides a high-definition representation of the aircraft — right down to the smallest parts — on computer screens. It also reinforces Airbus’ role as an integrator, and capitalises on the company’s decades of experience from previous programmes.This very realistic digital version of the A350 XWB has literally changed the way aircraft are conceived, as it allows an accurate visualisation of where systems are located during design, how they are installed in production and what access is available for maintenance during the jetliner’s operational lifetime.
Embraer E-Jets E2 truly innovative
The Embraer E-Jet E2 family is a family of three narrow-body medium- range twin-engine jet airliners developed by Brazilian aerospace company Embraer, replacing the predecessor Embraer E-Jet family. The three variants share the same fuselage cross sections with different lengths and three different new wings, Pratt & Whitney PW1000G geared turbofans in two sizes, fly-by-wire controls with new avionics, and an updated cabin with 40 per cent enlarged baggage bins. Announced improvements per seat are 16 to 24 per cent lower fuel burn and 15–25 per cent lower maintenance costs. The E2 features a closed loop fly-by-wire control, which – according to Embraer – reduces weight, increases fuel efficiency, enhances control and increases safety by full envelope protection in all flight phases.
Analysts account the fuel savings of the now closed loop fly-by-wire control at 1.5 per cent because of design changes possible due to the enhanced flight stability and the resulting increased lift (lower tail downward force) and weight savings and drag reductions related to the 26 per cent reduction in the horizontal tail size. The E2 family has a new wing and landing gear In the E190-E2, of the 16 per cent better fuel burn, 11 per cent comes from the geared turbofan, 3.5 per cent from the improved aerodynamics of the new high aspect ratio wing and 1.5 per cent from the fly-by-wire, enabling a 250 ft horizontal stabiliser from 280 ft on the E190/ E195.
The E2 family has AHEAD-PRO, which is a computational web-based platform to continuously monitor the health of the fleet, providing timely maintenance information in a friendly and straightforward way. With AHEAD-PRO aircraft systems health condition is systematically assessed and unplanned maintenance of monitored systems is avoided by means of failures occurrence prediction. Moreover the activities of fault identification, troubleshooting and resources planning occur before the aircraft lands its destination, optimizing airline turnaround- time between flights. AHEAD-PRO offers functionalities to optimize all steps to execute Health Monitoring process in the airline, from data acquisition to time-to-failure prognosis.
THE NEW TECHNOLOGIES ARE CENTRED AROUND OPERATIONAL EFFICIENCY WHICH WILL FACILITATE IMPROVED SCHEDULE RELIABILITY AND PASSENGER SERVICES
E2’s advanced integrated avionics system provides exceptional situational awareness enhanced by large landscape displays and reduced pilot workload. Innovative technologies such as synthetic vision and advanced flight management support more fuel-efficient direct approaches to airports.
