In launch event on Friday, agency shared plans to test over US cities to see if it’s quiet enough by engaging ‘the people below’

Nasa has unveiled a one-of-a-kind quiet supersonic aircraft as part of the US space agency’s mission to make commercial supersonic flight possible.

In a joint ceremony with Lockheed Martin Skunk Works in Palmdale, California, on Friday, Nasa revealed the X-59, an experimental aircraft that is expected to fly at 1.4 times the speed of sound – or 925mph (1,488 km/h).

The aircraft, which stands at 99.7ft (30.4 metres) long and 29.5ft wide, has a thin, tapered nose that comprises nearly a third of the aircraft’s full length – a feature designed to disperse shock waves that would typically surround supersonic aircraft and result in sonic booms.

pretty neat that the image of the plane for the article is shot from so close that you can only see 1/3 of it, but to be fair it does include the screens of people's phones as they take a picture of the thing. kind of like going to a concert.

[-] Nudding@lemmy.world 9 points 10 months ago

Haha I wonder about the ungodly amount of fuel it burns.

The website blasted me in the ass with ads, while simultaneously begging for donations

[-] Marsupial@quokk.au 5 points 10 months ago

Yeah but with the pictures on the phones, we actually end up with more picture per picture with this method.

[-] conditional_soup@lemm.ee 3 points 10 months ago

Yo dawg, I heard you like pictures

It's proportions make it hard to frame it for an article headline picture. This is cropped to show a colorful array of the fun parts: cockpit, landing gear engine intake with a clear X-59. It's like trying to make a cover picture feature a pencil.

This other article uses a dramatic background to fill the space. It's from NASA though, so they're not limited to the conference. They don't have to have their own picture to say "I was there"

Please don't. We need to be reducing air travel, not increasing it. Go invent a quiet supersonic train or something.

[-] Swedneck@discuss.tchncs.de 11 points 10 months ago

the transatlantic railway is feeling less and less like a funny absurdist joke by the hour

[-] MrBusiness@lemmy.zip 3 points 10 months ago

Let's get started on the Snowpiercer too

[-] Narauko@lemmy.world 5 points 10 months ago

What is your plan for intercontinental travel? Increased ship travel, taking a week and burning massive amounts of crude fuel oil? Just cut off the Americas and Australia from Europe, Africa and Asia for non-commercial purposes? The supersonics have mostly been used for trans-atlantic and trans-pacific travel.

[-] llii@feddit.de 8 points 10 months ago

Less and more efficient airplanes. Supersonic aircraft will consume more fuel.

[-] MrBusiness@lemmy.zip 5 points 10 months ago

Let's get weird with blimps

These kinds of comments only say it’s wrong; they never make a valid contribution to finding a solution.

Now the fuel efficiency problem needs to be reckened with. The sonic boom was the main reason why supersonic planes were shelved but poor fuel efficiency was the other 800 pound gorilla in the room.

[-] BruceTwarzen@kbin.social 15 points 10 months ago

That's what we really need right now. Faster air travel for fewer people.

[-] LibertyLizard@slrpnk.net 6 points 10 months ago* (last edited 10 months ago)

But how else will the ultra-wealthy jet over to their summer homes in new Zealand when wet bulb temperatures exceed human survival in the Northern Hemisphere?

[-] AbouBenAdhem@lemmy.world 14 points 10 months ago

Pierce said the X-59’s job would be to “collect data from the people below, determine if that sonic thump is acceptable and then turn the data over to US and international regulatory authorities in hopes to then lift that ban”.

Why can’t commercial airlines fund the project, then? Why is NASA investing public money to deregulate private industry?

[-] GBU_28@lemm.ee 42 points 10 months ago

Huh? NASA is providing thought leadership to expand the possibilities of human travel, but has no interest in running a commercial airline.

Many technologies you use every day started as NASA research

The first A in NASA is aeronautics. They just do the science. I would say deregulation is a fairly strong word here. It's more like they'd be updating the laws to reflect modern tech.

[-] Artyom@lemm.ee 12 points 10 months ago

This is literally how every expensive R&D project gets done. Private companies won't dump this kind of money into good R&D, but the government will because they don't care about ROI.

[-] You999@sh.itjust.works 2 points 10 months ago

Except this ignores the existence of bell labs, you know the private R&D lab with ten Nobel prizes and a laundry list of inventions that quite literally shaped our modern world.

Deregulate is not the same as engineering a solution to solve the problem that was previously solved by regulations.

This is probably defense spending, tbh.

Looks to me like a climate change accelerator for rich people. Fewer people per flight, spending more fuel to go faster.

I would be disappointed if the prototype isn't nicknamed Pinocchio.

[-] Anticorp@lemmy.world 4 points 10 months ago* (last edited 10 months ago)

This is pretty amazing! This thing could take people from Los Angeles to NYC in 3 hours. The science behind the noise baffling is really cool.

[-] Aceticon@lemmy.world 3 points 10 months ago

Wouldn't suborbital flight be a lot more fuel efficient?

They are still in the prototype stage. If they can prove the physics on small planes, they can scale up for commercial ones.
