Tim, Bold Inquiry on A350 Engine: Rolls-Royce Assures Guaranteed Engine Performance

Airbus SE’s hopes of securing a sizable order at the Dubai Air Show were stopped by Emirates President Tim Clark, who declared that he would not purchase any more of the company’s flagship A350-1000 until engine performance issues were resolved.

Emirates Seeks Assurance on A350 Engine Performance

Clark told reporters during a press conference at the Dubai Air Show, “If they can do that at a maintenance cost per hour, that’s alright for us,” Emirates would order the aircraft.

In regions like the Middle East and India that are hot, dusty, and sandy, engines have unique difficulties. Monday’s opening of the week-long Dubai Airshow was dominated by Emirates’s order for ninety additional Boeing 777X aircraft powered by GE.

Earlier, the Qatar CEO expressed concerns about the poor paint peeling on the A350, raising airworthiness risks. Airbus subsequently addressed and resolved the issue. Now, the Emirates Chief is questioning the engine’s ability to withstand extreme heat, anticipating increased maintenance and downtime challenges.

R-R’s unique supplier engines ensure 2500 cycles

Rolls-Royce has responded, assuring the performance of the Trent XWB-97 engine with the following statement.

“The engine excels in benign operations but faces challenges in sandy, hot conditions, like many modern engines. Rolls-Royce is actively enhancing durability. Emirates considers ordering up to 50 A350-1000 only if R-R’s unique supplier engines ensure 2500 cycles on the wing before maintenance, a significant leap from the current Trent XWB-97 performance.”

Only Rolls Royce Holdings Plc is responsible for building the aircraft, and Clark claimed that until the next maintenance cycle, the engine on the aircraft does not meet the requirements of so-called time on the wing. According to Clark, Emirates is considering purchasing 35 to 50 A350s, which would supplement their current order of 50 A350s of the smaller -900 widebody model.

According to industry sources, Airbus saw a second significant order from Turkish Airlines slip off the show’s agenda when plans for an Emirates A350 order were put on hold for the time being.

Boeing has achieved a significant milestone by providing NASA with the second core stage of the Space Launch System (SLS) rocket.

This crucial component, crafted at NASA’s Michoud Assembly Facility (MAF), is set to propel the Artemis II crew into lunar orbit, marking humanity’s return to deep space after a 50-year hiatus.

The monumental Boeing-built rocket stage, the largest element of the Artemis II mission, will embark on a journey aboard the Pegasus barge, traveling 900 miles to NASA’s Kennedy Space Center.

Upon arrival, it will be meticulously integrated with other essential Artemis II components, including the upper stage, solid rocket boosters, and NASA’s Orion spacecraft within the iconic Vehicle Assembly Building. This intricate integration process is a vital step toward the eagerly anticipated Artemis II launch, slated for 2025.

“Boeing-built products helped land humankind on the moon in 1969, and we’re proud to continue that legacy through the Artemis generation,” remarked Dave Dutcher, vice president and program manager for Boeing’s SLS program. “Together, with NASA and our industry partners and suppliers, we are building the world’s most capable rocket and paving the way to deep space through America’s rocket factory in New Orleans.”

The delivery of Core Stage 2 marks a significant achievement in the evolution of the SLS rocket. Towering over 200 feet and powered by four RS-25 engines, this core stage, coupled with two solid-fueled booster rockets, will generate a staggering 8.8 million pounds of thrust. This immense power is crucial to launching Artemis II and future missions into the vast expanse of space.

The SLS rocket stands unparalleled in its capability to transport both crew and substantial cargo to the moon and beyond in a single launch. Its extraordinary capacity will facilitate the delivery of human-rated spacecraft, habitats, and scientific missions to destinations including the moon and Mars, ushering in a new era of space exploration.
