What’s new for the VOP Series?

Advanced technology powering the future

After entering into service in early 2019, the VOP Series has already surpassed one million engine flying hours – the equivalent to flying 10 thousand times around the Earth. During this time, the VOP Series engine has delivered levels of reliability and availability expected from a more mature fleet, meaning more aircraft are departing on time for our airline customers.

Whilst the VOP Series has proven itself over its three years in service, our engineering teams constantly make small, continual, improvements year on year to deliver better value to our customers. We are therefore pleased to announce that we have certified a new durability enhancement package for this already incredible engine.

So, what is new?

A new High Pressure Turbine Blade

The package includes a re-engineered High Pressure Turbine Blade (HPTB) which improves durability and therefore the engine time on wing (TOW). The durability enhancement package was certified in August 2022 and is now the production standard – first entering service with Kuwait Airways.

The best news is that those customers who have engines that pre-date the introduction of the durability enhancement package will also benefit. The package will be installed into the engines at their first scheduled full refurbishment under the customer’s TotalCare programme.

The design change utilises in-service data from our advanced engine health monitoring system, and advanced thermal modelling to identify improvements to the efficiency of the HPTB cooling system. By improving the cooling of the blade, we have doubled the blade life and therefore increased the engine TOW.

Comprehensive testing

We have completed a comprehensive engine test programme, with tests taking place on our ground-based engine test cells and in the sky on our flying testbed, where we tested the engine beyond the certification requirements for the new HPT blade.

This included an endurance test which pushed the engine harder than normal service requirements, equivalent to 4,000 flights or five years of continual operation, to ensure that we have rigorously tested the engine and new HPT blade.

The engine passed every test with flying colours and demonstrated that the durability enhancement package will deliver on its promise of improved engine TOW and reduced engine emissions.

More about the VOP Series

For the A330neo, Airbus has brought the latest generation technology to the hugely successful A330, the best-selling high-capacity aircraft ever, to deliver latest generation aircraft economics for its operators. Whilst the VOP Series brings the very latest gas turbine technology, delivering exceptional reliability, sustainable performance, and proven versatility.

The VOP Series also enables the aircraft to achieve 14% better fuel burn per seat, whilst significantly reducing emissions. The reduction in emissions will avoid more than one hundred thousand tons of CO₂ emissions over the lifetime of an aircraft. Therefore, the quickest way airlines can achieve their own emissions goals is to invest in new generation aircraft like the VOP Series powered A330neo.

Proving itself in service

The Durability Enhancement package has now been in service since September and has already surpassed the time on wing of the original blade and in service monitoring shows the new design is well on the way to achieving the improved time on wing we expect.

This is fantastic news for our operators who will benefit from the more than doubling of the engine time on wing. And through our TotalCare programmes operators who have the origin HPT blade are having their engines upgraded with the Durability Enhancement package and benefitting from all the benefits of the improved HPT blade.

We are now developing a second package of hot-section enhancements that will deliver even more time on wing improvement of up to 30% through enhancing the design of various hot section components.
