CRAZY Jet Engine Mod - ATA Air Brake

Issues of aircraft noise in the communities surrounding airports have long been a concern; however, developing noise mitigation methods for aircraft without decreasing performance or fuel economy has proven challenging. ATA’s EAB has been designed to address these challenges through the use of a deployable swirl vane mechanism to switch the operation of a turbofan engine nozzle from conventional mode to a “drag management” mode. In this mode, swirling outflow from the thrust-generating exhaust stream allows an aircraft to generate equivalent drag in the form of engine thrust reduction at a fixed fan rotor speed;

It’s mind-boggling how those moving parts withstand that amount of air flow pressure

[JackRLong]

Yeah, the first time a maintenance member screws up and has anything in that area when testing is gonna have a shit day

Why would this ever *replace* thrust reversers? Fundamentally different objectives - reduce thrust vs reverse thrust

[BrowithStoryCool]

What does this solve that simply turning the engines down to idle doesnt?

[davidyoung]

What happened to the KISS (Keep It Simple Stupid) mentality. Not to mention the increased number of things to go wrong there. And I don't see any form of redundancy. Otherwise....pretty cool!!

'Could see this potentially being useful for Naval Aircraft.

[OrenWasser]

it takes some time to change thrust from idle to full, . which is critical when landing. it might solve this issue

[Ausiedundan]

Is this like reinventing the wheel, with a square wheel?

[Gabriankle]

That IS quiet. Very little sound difference between deployed and stowed.

My Mom would love building engineering this stuff

[ronparrish]

Still like the original 737 200 original clam shell design simple looked neat and it worked

[Mallchad]

I don't understand the purpose of this, to reduce thrust?
Since when was that ever something we needed?

[skybreaker]

Does anybody have a 3d model of this that I can 3d print

So it wastes energy to steepen descent. Fan blades coupled to electric motor and batteries could steepen descent more and recover energy and likely make less noise. Joby aviation electric aircraft will prove this despite its smaller wing.

😮🙏 The simpler the system the Better & Safer as there will be Less Hardware & Software Complications ... 🙏🕯🌍✌🕊

Thise springs remind me if drum brakes.

All that would do is create a vortex. Silly and a waste of time and money.
