and now for your regularly scheduled aeronautical insanity: who needs one tail rotor when you can have four?



quote:

Bell has revealed a groundbreaking new electric anti-torque system in development for its commercial helicopter line, one that promises enhancements to safety and operating cost, as well as a reduction in noise compared to an aircraft with a conventional tail rotor.

The electrically distributed anti-torque (EDAT) system is composed of four small fans within a tail rotor shroud in an offset two-by-two pattern. Each of the rotors contains four blades, and they are powered by four separate motors, with the electrical energy provided through generators driven by the turbine engines.

“In a nutshell, we removed all of the conventional mechanical anti-torque components — which is gearboxes, driveshafts and tail rotor hub and blades — and replaced it with four electric motors and fans,” Eric Sinusas, program director of light aircraft at Bell, told Vertical. “They are fixed-pitch blades and they’re changing rpm constantly.”

The system has been installed on a Bell 429 demonstrator aircraft at Bell’s facility in Mirabel, Quebec, and began flight testing on May 23, 2019. Since then, the program has completed about 25 flight hours, with the aircraft gradually expanding its flight envelope.

...
The system’s anti-torque fans are controlled through pedals, as with yaw control in a traditional helicopter, but the link between the pedals and the motors is entirely electric “fly-by-wire” — all mechanical linkages and the control tubes of a conventional system have been removed. Other than the tail rotor and the control mechanisms, the demonstrator aircraft is unchanged to accommodate the system, using a conventional main rotor, engine, and airframe.
...
“We were looking at what are the customers demanding for aircraft? . . . And safety is obviously always at the top of the list,” he said. “This [system] certainly meets those [requirements] and it has some interesting features that conventional rotors don’t with redundancy, and when the aircraft on the ground, the electric fans are not rotating at all.”

The redundancy is extensive, with the aircraft capable of still producing a level of anti-torque thrust even if three of the four fans become inoperable.

When something that looks so oddly clumped together, you instantly know for sure there will never be a fully mature version of it. It might be a dead end or it might trigger a revolution in helicopters, but that particular config will not be long for this world.

So, here is the thing. If we do one big one, we gotta find someone to make the motor. Then getting it certified is going to be a pain in the rear end because we'll have to figure out failure mode. But we do have these smaller off the shelf motors we can use today. We just need like 3 of them. Ok, gently caress it, put 4 back there and lets see if we can make it work.

Dear diary, I got another erection today at work. SO embarrassing, but kinda hot. The CO asked me to fix up his dress uniform. I had stayed late at work to move his badges 1/8" to the left and pointed it out this morning. 1SG spanked me while the CO watched, once they caught it. Tomorrow I get to start all over again...

Well, the main thing in Boeing was that at some point they had a excellent understanding of manufacturing and engineering aircraft - and they understood that all the practices, and workers, and methods that went along with that were necessary. The way to keep making money was via quality and innovation: both because modern airliners demand the quality for both marketing and prudential reasons, and because thanks to those prudential concerns made safetly and its attendant regulations very important. At some point the finance bros came in with their one-size-fits-all wrecking ball and choose short term profits by producing products faster and cheaper. They got cheaper, less skilled workers, they kept insisting automated processes were fine when by the old standards they weren't and were costing extra compared to the older processes, they hollowed out the RnD-engineering base, they stopped giving a poo poo about programming practices, they played the federal regulator for a fool, they got employees to lie, etc etc. In a consumer company, like cars or something, people would figure out that the cars were lovely and for the most part stop buying them. But in airliners, you can't do that for very long until something dramatic happens, and so here we are, with a type of Boeing grounded permanently after killing two planeloads of people.

The thing that keeps this from happening at airbus is the same thing that once worked at Boeing: valuing those practices I outlined above. Because this is a god-cursed election year, I'm sure lots of people will want to valorize/villainize Boeing being privately owned, but I think most people ITT know really big aerospace is so closely linked with government that it is the tyranny of small differences between Boeing and Airbus's structure. So yeah, this is not happening at Airbus as far as I know, but it could.

On Heli safety, my last foray into them was in highlands of PNG through fog and not a lot of visibility,. The area had a few recent tribal murders and the mountains were alive with itchy bush-knives. And here I was more annoyed at how long it took for the pilot to take the doors off so I could hang out the side when flying in some dangerous air over dangerous ground.

After the last few years of Boeing software quality, it’s somewhat reassuring that the SLS software is being built by NASA.

https://www.nasa.gov/sites/default/files/files/FlightSoftware.pdf

Apparently there were parts of Boeing who felt that the “Green Run” tests (instrumented rocket core in test stand flies the entire launch sequence) amounted to “workmanship testing” and we’re hoping they could convince NASA to abbreviate them somewhat.

Flight software is still titled Flight Computer Application Software (FCAS) though. With its testing counterpart Green Run Application Software (GRAS). Hopefully it won’t have to save the day.
