i buy a lot of random motorcycle parts on ebay, because there's nowhere else you can go "yeah I need the passenger pegs from a 1992-1997 VFR750" and have any luck also used tools -- lots of good things there strange russian electronic devices most recently a digital piano basically, it's great for weird odds and ends that you can't find just anywhere and where it doesn't matter if they're used

Lots of European countries have an extra yellow phase after red, before green, to let people get ready. It's incredibly stupid. America does traffic lights the right way. Random fun fact: I learned this about Euro traffic signals after I had some British students in my Arduino class, which has as one of its first projects "use six LEDs and a button to simulate an intersection with a pedestrian-controlled signal." I thought the kids were just loving it up until I noticed a pattern among all the exchange students and went and looked it up

i'd imagine they also wouldn't have quite as bad a reputation if their rebuttal to nader's book hadn't been to tap his phones, try to get him in bed with hookers, and dig up dirt on his family members they certainly wouldn't have quite as bad a reputation if they hadn't been so blatant about the above that they had to admit to all of it in a public senate hearing all those jokes about GM being run by thugs came from somewhere

san francisco's tap water is so pure they don't even have to filter it. comes straight from the hetch hetchy reservoir in yosemite and they add chlorine and put it in your pipes, that's it. so naturally everyone only drinks filtered water.

FMguru posted:they still really dont know what the maximum speed was on those things. every pilot had a personal max speed but they all think they could have gotten another 20 or 50 or 75 km/hr out of the thing if they had to. same with max altitude yeh. the engines were ramjets, which use the aircraft's forward motion to compress the intake charge, so the upper limit on its speed is "the intake cones/wing leading edges/cockpit windows just melted" rather than anything to do with the plane running out of power

i see your best sr-71 story and raise you the other best sr-71 story e: gonna quote the meat of it because everyone needs to read it quote:We got a little lower, and I pulled the throttles back from 325 knots we were at. With the gear up, anything under 275 was just uncomfortable. Walt said we were practically over the field-yet; there was nothing in my windscreen. I banked the jet and started a gentle circling maneuver in hopes of picking up anything that looked like a field. Meanwhile, below, the cadet commander had taken the cadets up on the catwalk of the tower in order to get a prime view of the fly-past. It was a quiet, still day with no wind and partial gray overcast. Walter continued to give me indications that the field should be below us but in the overcast and haze, I couldn’t see it. The longer we continued to peer out the window and circle, the slower we got. With our power back, the awaiting cadets heard nothing. I must have had good instructors in my flying career, as something told me I better cross-check the gauges. As I noticed the airspeed indicator slide below 160 knots, my heart stopped and my adrenalin-filled left hand pushed two throttles full forward. At this point we weren’t really flying, but were falling in a slight bank. Just at the moment that both afterburners lit with a thunderous roar of flame (and what a joyous feeling that was) the aircraft fell into full view of the shocked observers on the tower. Shattering the still quiet of that morning, they now had 107 feet of fire-breathing titanium in their face as the plane levelled and accelerated, in full burner, on the tower side of the infield, closer than expected, maintaining what could only be described as some sort of ultimate knife-edge pass.

fishmech posted:the sr-71 was explicitly designed to reduce radar cross-section, why would they have not thought about it??? the sr-71 was never hard to detect and everyone on all sides knew it. the three main things people talk about as reducing the plane's rcs (the iron-bearing paint, the chines, and the canted tails) were implemented for heat management, mach-tuck prevention and high-alpha (landing) performance, and increased yaw control, respectively. none of those were intentionally implemented to try and reduce RCS because the plane is spewing a mile-long trail of disturbed heated air that, at 80,000 feet, shows up like a searchlight on a radar scope. the main reason the sr-71 could escape radar locks is because the systems in use through the early 1970s weren't able to acquire, track, and engage a target moving as quickly as the sr-71 before it went out of range. but please pull more stuff from whatever is the first google result that supports your beliefs

Yeah. Back in the day the same was true of surface-to-air missiles. Even if they could find the plane, hand it off from the long range search site to the missile base, track the plane until it got in range, launch the missile, switch to guidance mode, and fly the missile to the target while keeping the plane in the line of sight...well by the time the missile got to 80,000 feet it would be in a tail chase and out of fuel at an altitude where the control surfaces barely work so the Blackbird would just have to turn a bit and be a mile to the side in 1.8 seconds. [quote="fishmech" post="481087880, reducing that cross section would be an ongoing goal from the mid 50s because of this, eventually resulting in knowledge learned being applied to "true" stealth aircraft like the nighthawk [/quote] The F-117's stealth features were based on a theory of electromagnetic wave propagation published by a Russian mathematician in the 1970s.

silence_kit posted:I’m unfamiliar with the history here, but I feel like Notorious b.s.d.’s point regarding there not being enough computing horsepower to solve Maxwell’s equations numerically back then is relevant. I suspect that to actually be able to do a careful design of an aircraft’s shape to reduce radar cross-section, numerical solution of Maxwell’s equations is required. More or less, yeah. IIRC when the HAVE BLUE project started (in the mid-70s) they still didn't have anything capable of getting a full simulation of radar diffraction in three dimensions. The Russian paper proposed an approximate solution to the problem based on surface edges, and Lockheed engineers were able to expand that into a program that could calculate the RCS of a set of flat polygons. That's why the F-117 looks like it do. Later developments let the technique be generalized to any shape, given enough computer power, which is why the B-2, F-22, and F-35 all have smooth rounded surfaces.

cool startup feel posted:remember that time he used his wife as a breeding sow and then divorced her for a younger woman? quote:As we danced at our wedding reception, Elon told me, "I am the alpha in this relationship." I shrugged it off, just as I would later shrug off signing the postnuptial agreement, but as time went on, I learned that he was serious. He had grown up in the male-dominated culture of South Africa, and the will to compete and dominate that made him so successful in business did not magically shut off when he came home. This, and the vast economic imbalance between us, meant that in the months following our wedding, a certain dynamic began to take hold. Elon's judgment overruled mine, and he was constantly remarking on the ways he found me lacking. "I am your wife," I told him repeatedly, "not your employee."
