It’s my understanding that LA center entered VFR/OTP for a U-2 in class E airspace above FL600, which caused an immediate dual-channel ERAM failure, which also propagated to DARC (our oh-gently caress-gently caress-gently caress backup hardware) through the flight plan processing interface. That error has since been fixed, but Miami center experienced a similar dual-channel/DARC failure caused by a different bug a few weeks afterwards.

slidebite posted:I always thought the deluge was more for sound suppression than heat? Either way cool as hell. It's both. The deluge system keeps acoustic waves from being reflected back into the booster (or the launch pad hardware) with enough energy to do damage, and it also absorbs some heat in the process. The giant geyser in the video is only there because the launch platform isn't in place, since most of that water would get sent through plumbing to various nozzles installed on the launch platform.

Is there a reason we don't see what's basically a wing on the top of a car? Like instead of roof racks, a flat (ish) platform in the shape of an aerofoil, slightly raised above the roof? Would it provide enough lift to improve fuel efficiency, or would it provide too much lift and make them less controllable? Would the downward force of an upside-down one help at all? Or would none of them really do anything? I know that roof racks are a major source of drag and reducing fuel efficiency, just wondering about ways around that.

Or would none of them really do anything? Force on the axles has quite a small impact on fuel economy. You won’t save anywhere near enough there to offset the inevitable increase in drag. If you have to have a roof rack, you can optimise its shape to create less drag, but adding drag to get lift is never a good idea (for fuel economy, on a ground vehicle).

Isn’t that the functional purpose of a spoiler, to push a car down to keep friction high between the tires and the road, allowing greater control?

Would it provide enough lift to improve fuel efficiency, or would it provide too much lift and make them less controllable? Would the downward force of an upside-down one help at all? Or would none of them really do anything? Cars are fighting against lots of different frictions. One of those is the rolling resistance due to downward force on the tires from the weight of the vehicle sure, but that one is effectively a linear relationship between speed and friction. It also pales in comparison to the major frictional killer: air resistance. Realize that to create lift you need motive force, and if youre using your motive force to both overcome air resistance and achiece lift, you're creating more friction. Some of it is offset by the loss of rolling resistance, sure, but as air resistance increases by the square of speed, the faster you go the more lift you create the more losses you create from air resistance.

Cool, thanks heaps guys, kind of what I suspected. edit: I guess I was kind of wondering if we can apply any of the advantages of hydrofoils on boats to cars, but I guess the answer is that water and air are two wildly different densities so it's a whole seperate thing, right? https://www.youtube.com/watch?v=sQaYRjAIbhs Bucky Fullminster fucked around with this message at 04:14 on Oct 25, 2018 |

This is going to sound trivial, but if you take the “put a wing on it to take weight off the wheels” idea to its extreme, you end up with an æroplane. Planes have never been accused of being economical.

Wings create a lot of drag. They work for race cars because the increase in speed they provide in turning more than makes up for the lost top speed in the straights (and/or prevent the car from taking off in the wind)

I can say with 100% certainty that the last thing I want in a ground vehicle is anything taking weight off the wheels. Friction is the thing that allows us to do nifty things like turn and stop, things which are cool and good to do in a vehicle that's on the ground. Look at the procedure for a short-field landing in most airplanes: deploy any lift spoilers you have and make sure the flaps are up. Otherwise you'll have an aircraft just on the edge of flying with no weight on the wheels and you can't do jack poo poo to slow it down or turn (though if your goal is to produce some lovely huge flat spots on tires, you've set yourself up wonderfully). I suppose that may be good for efficiency in theory, disregarding the added drag, which would probably kill any efficiency gains, but it would produce an absolutely terrifying driving experience, especially in anything not designed for aerodynamic stability.
