Today's KNOWLEDGE Share:

Rolls-Royce has entered the final build phase for the world's largest aero-engine technology demonstrator, UltraFan, which provides a suite of technologies to support sustainable air travel. The demonstrator engine, with a fan diameter of 140 inches, is being completed at the company's facility in Derby, UK, prior to its first run on 100% Sustainable Aviation Fuel (SAF) later this year. It offers a 25% fuel efficiency improvement compared with the first generation of Trent engines!


Chris Cholerton, President — Civil Aerospace, Rolls-Royce, said, "Our UltraFan engine technology demonstrator is arriving just as the world is seeking transformative technology to deliver sustainability. We are now in the final build phase and we will perform the first test run on 100% sustainable aviation fuel later this year. The suite of technologies we are testing on the demonstrator will create opportunities to make improvements to our current fleet and provide a new capability for future propulsion systems.


Key engineering features of the engine include:

- Carbon titanium fan blades and a composite casing.

- A new, proven, Advance3 core architecture, combined with our ALECSys lean burn combustion system, to deliver maximum fuel burn efficiency and low emissions.

- Advanced ceramic matrix composite (CMC) components that operate more effectively at high pressures and temperatures.

- A geared design that delivers efficient power for the high-thrust, high bypass ratio engines of the future. The power gearbox has run at 64MW, an aerospace record.

Today's KNOWLEDGE Share:PLA BOTTLE

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

-

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio
