Rolls-Royce Launches Test Flights for Revolutionary Pearl 10X Engine

Rolls-Royce Launches Test Flights for Revolutionary Pearl 10X Engine

Rolls-Royce reports that the company’s dedicated Boeing 747 flying testbed has seen the successful start of the Pearl 10X, their newest aero engine designed for the business aviation industry.

Dassault, a French aircraft manufacturer, has decided to use this engine only to power their newest flagship, the Falcon 10X. As stated at last year’s Capital Markets Day, the commencement of flight testing represents a significant milestone for both Rolls-Royce and the Pearl 10X programme as the company concentrates on expanding in the business aviation industry.

The first Rolls-Royce engine to power a Dassault business jet is the Pearl 10X, the newest engine in the state-of-the-art Pearl engine family. The Pearl 10X was chosen by the French aircraft manufacturer as their new flagship model, demonstrating even more of Rolls-Royce’s dominance in the business aviation engine market.

Over the next few months, pilots and flight test engineers from Tucson, Arizona, USA, will put the engine through its paces. The flight test programme will comprise testing of the nacelle’s anti-icing system, in-flight relights, engine performance and handling checks at various speeds and altitudes, and fan vibration tests at various altitudes.


The new auxiliary gearbox, which enables higher additional power extraction, and the ultra-low emissions ALM combustor, which is compatible with 100% Sustainable Aviation Fuel (SAF), have undergone extensive testing as part of the ground-based development programme thus far. The engine will be the most potent business aviation engine in the Rolls-Royce lineup. It exceeded its intended thrust levels during the very first test run. With over 2,300 testing hours successfully completed on the Pearl 10X engine configuration as well as the Advance 2 demonstration, the programme is moving forward at a rapid pace.

With the most economical engine core available for business aircraft, the Advance2 engine, coupled with a high-performance low-pressure system, gives the Pearl 10X an exceptional thrust of over 18,000 lbf. With a 5% increase in economy over the previous generation of Rolls-Royce commercial aviation engines, the Pearl 10X



Boeing 777-9 Begins Certification Flight Testing with FAA Onboard

Boeing 777-9 Begins Certification Flight Testing with FAA Onboard

The 777-9 has commenced certification flight testing at Boeing Field in Seattle. This is a crucial step under the supervision of our regulator to certify the airplane and deliver it to customers worldwide.

Amidst Boeing’s current challenges, the B777X stands out as a project that could revitalize the brand. It is highly anticipated, and Boeing is keen to clear FAA certifications to release it as soon as possible.

The aircraft is two years behind its initial commitment date. During this time, the company has rigorously tested it under various conditions to ensure its readiness for commercial service.


Boeing has announced that the 777X will be used for both passenger and freighter services, depending on customer requirements.

Boeing’s 777X program has achieved a major milestone with the Federal Aviation Administration (FAA) granting approval to begin certification flight tests, marking a significant step towards the aircraft’s entry into commercial service.

The European Union granted approval for this merger in February, and Korean Air anticipates U.S. regulatory approval by the end of October.


Following Airbus’ breakthrough with Korean Air, Reuters reported in April that Korean Air was considering a new Boeing order focused on the 777X, an advanced version of the 777 mini-jumbo.

Boeing 777-9 First certification

The first certification flight test of the 777-9 took place on Friday evening, with FAA personnel onboard alongside Boeing’s pilots and flight test team.

According to The Seattle Times, the aircraft departed from Boeing Field shortly after 6 p.m. and landed nearly two hours later after flying along the Washington and Oregon coast.

The 777X, an upgraded version of the successful 777 twinjet, features new engines and carbon composite wings with folding wingtips to accommodate standard airport gates.


The first variant, the 777-9X, is designed to carry 426 passengers in a two-class configuration for long-haul international flights.

Boeing B777x total orders

Boeing has secured 481 orders for the aircraft, with Emirates being the largest customer, having ordered over 200 units. The planemaker has already built and stored 22 777X jets, with an additional six in various stages of assembly in Everett, Washington.

Boeing is close to finalizing a significant deal to sell approximately two dozen 777X jets to Korean Air, with an estimated value ranging from $4 billion to $6 billion, as reported by Reuters.


Industry sources suggest that the agreement could be concluded as early as the Farnborough Airshow in July. Korean Air, South Korea’s largest airline, has been in discussions about returning to Boeing for its long-haul aircraft needs.

The Boeing 777X vs A350 is one of the most popular comparisons among aircraft as of now. The Airbus A350 has been operating for more than eight years, and its promising performance helps airlines in terms of efficiency and customer satisfaction, particularly in noise and vibrations.

The next generation Boeing 777X can fulfill the same requirements, with 777x first delivery given to Emirates Airlines, the launch customer for this aircraft. It remains to be seen how the Boeing 777X vs Airbus A350 will compete against each other in the future.
