One of the benefits of retirement and impending old age is the privilege of sitting in my easy chair and musing, and in doing so I think often of the contributions of Mr. Rolls and Mr. Royce to the West - especially their series of aviation piston engines of the 'thirties and 'forties - and of course, the remarkable series of gas turbine engines. One never knows from just where greatness will come; when seven-year-old Elon Musk was bombing around South Africa on his bicycle, did his parents ever imagine his place in the world? Doubt it.

Major hat tip to Rolls-Royce for their commitment to being the best.

“The company noted that the Trent XWB uses 15 percent less fuel than its first Trent engine and is capable of operating on 50 percent sustainable aviation fuel (SAF). ”. Why did the marketing people at RR ruin an otherwise good report with patronage to the enviro extremists? Note they mention nothing about the fuel consumption when using plants for fuel which people and livestock could otherwise eat. If it’s anything like ethanol, it’s terrible. Ethanol has only 70% of the energy per gallon compared to Mogas, which itself has slightly more than leaded Avgas. Eat plants, frack everywhere!

The average jet airliner burns one gallon of fuel per second. How many gallons were used to attain to 10 million hours? How many of those hours spent, were really necessary?

They are talking fleet operational hours, not hours of testing.

Yawn. Death, taxes, and Kent M whining every time an AVweb article mentions any attempt to take the long view in regards to the planet.
