“@JamesWorldSpace SpaceX & Boring Co engineers headed to Thailand tomorrow to see if we can be helpful to govt. There are probably many complexities that are hard to appreciate without being there in person.”
“Engineering is magic”
“@leechy3 @kausthav_ray @SpaceX SX 300 & soon SX 500. Kind of a modern version of Inconel superalloys. High strength at temperature, extreme oxidation resistance. Needed for ~800 atmosphere, hot, oxygen-rich turbopump on Raptor rocket engine.”
“@kausthav_ray @SpaceX Structures, engines, avionics, guidance & control software, new alloys, space lasers (ooh, maybe I shouldn’t have said that) …”
“SpaceX option package for new Tesla Roadster will include ~10 small rocket thrusters arranged seamlessly around car. These rocket engines dramatically improve acceleration, top speed, braking & cornering. Maybe they will even allow a Tesla to fly …”
“@unicorn @MacTechGenius @v_g_fischer @ConsumerReports Try adjusting tire pressure. Will ask Tesla engineering to investigate.”
“@annerajb @eli_schiff Good progress. Really proud of this design & SpaceX propulsion team. This engine is something special.”
“@JuBeBallin I just sent a note to Tesla service to take care of your car right away & our HVAC engineering lead to fix root cause”
“@ElecVehicleGuy @EVNewsDaily @Tesla Model 3 was designed for min engineering & tooling change for RHD. Note left/right symmetry. LHD for Europe & Asia first half of next year. RHD probably middle of next year.”
“@MacTechGenius That is true. Electric motors are far more reliable than combustion engines. You need an electric motor just to start a gas engine!”
“@DylanNeumann2 @Everman Exactly. Gasoline cars will be like steam engines — quaint, but not something you’d actually use to get around. Btw, I like steam engines & trains in general.”
“@amir About a year ago, I asked Doug to manage both engineering & production. He agreed that Tesla needed eng & prod better aligned, so we don’t design cars that are crazy hard to build. Right now, tho, better to divide & conquer, so I’m back to sleeping at factory. Car biz is hell …”
“@amir Can’t believe you’re even writing about this. My job as CEO is to focus on what’s most critical, which is currently Model 3 production. Doug, who I regard as one of the world’s most talented engineering execs, is focused on vehicle engineering.”
“@kerrbones @nextspaceflight Not enough ignition fluid to light the outer two engines after several three engine relights. Fix is pretty obvious.”
“Falcon Heavy engine plumes look like giant laser beams in this photo by rocketphotography https://t.co/d1RKdPTNj5 https://www.instagram.com/p/BfEHEiKgBiK/”
“Falcon Heavy launching from same @NASA pad as the Saturn V Apollo 11 moon rocket. It was 50% higher thrust with five F-1 engines at 7.5M lb-F. I love that rocket so much.”
“@Barnacules To be more inclusive, how about a "pick your tech level" setting. Could make the Tesla sound like horses (coconuts!), chariots, steam engines, gasoline cars, ...”
“@DiscoverMag That's a SpaceX engineer in there, not me”
“All systems go, except the movement trace of an upper stage engine steering hydraulic piston was slightly odd. Standing down to investigate.”
“@brandonr182 @sama Have you tried steam engines? They are amazing.”
“@rocketrepreneur Meant to say 200 AR for production vac engine. Dev will be up to 150. Beyond that, too much flow separation in Earth atmos.”
“Chamber pressure is almost 3X Merlin, so engine is about the same size for a given area ratio”
“SpaceX propulsion just achieved first firing of the Raptor interplanetary transport engine https://t.co/vRleyJvBkx”
“Important to note that this happened during a routine filling operation. Engines were not on and there was no apparent heat source.”
“Looks like early liquid oxygen depletion caused engine shutdown just above the deck https://t.co/Sa6uCkpknY”
“Turns out the landing was not as fast we thought, but still hard enough to destroy the primary airframe and accordion the engines”
“Upgrades underway to enable rocket to compensate for a thrust shortfall on one of the three landing engines. Probably get there end of year.”
“Looks like thrust was low on 1 of 3 landing engines. High g landings v sensitive to all engines operating at max.”
“@SpaceX There was a tiny glitch in the motion of an upper stage engine actuator. Probably not a flight risk, but still worth investigating.”
“@lukealization Max is just 3X Merlin thrust and min is ~40% of 1 Merlin. Two outer engines shut off before the center does.”
“Yeah, this was a three engine landing burn, so triple deceleration of last flight. That's important to minimize gravity losses.”
“@lukealization No physical changes to the engine. This thrust increase is based on delta qual tests. It is just tougher than we thought.”
“@Benzinga I didn't take anyone's car and never would. Car was actually allocated to engineering test (not by me) and inadvertently sold.”
“Maybe some debris ingestion. Engine data looks ok. Will borescope tonight. This is one of the outer engines.”
“Conducted hold-down firing of returned Falcon rocket. Data looks good overall, but engine 9 showed thrust fluctuations.”
“We are looking for hardcore software engineers. No prior experience with cars required. Please include code sample or link to your work.”
“Cause still unknown after several thousand engineering-hours of review. Now parsing data with a hex editor to recover final milliseconds.”
“@ID_AA_Carmack Rocket hits hard at ~45 deg angle, smashing legs and engine section http://t.co/PnzHHluJfG”
“@ID_AA_Carmack Before impact, fins lose power and go hardover. Engines fights to restore, but … http://t.co/94VDi7IEHS”
“Three engine F9R Dev1 vehicle auto-terminated during test flight. No injuries or near injuries. Rockets are tricky …”
“The gas generator is a small rocket engine that powers the turbopump, which produces 7000 horsepower & weighs 160 lbs”
“Engines are cycling cleanly w ground pneumatics. Replaced gas generator on engine 9 (center) as a precautionary measure.”
“Rocket engines are healthy, but cleaning turbopump gas generators will take another day. Aiming for Mon eve launch.”
“We called manual abort. Better to be paranoid and wrong. Bringing rocket down to borescope engines ...”
“If launch aborts, we will bring the rocket down for engine inspection, so probably a few days before next attempt”
“SuperDraco rocket engine fired at full thrust w a printed Inconel chamber. Used for Dragon escape & landing http://t.co/HjWEayLlBN”
“Engineers interested in working on autonomous driving, pls email autopilot@teslamotors.com. Team will report directly to me.”
“@arthurblake Turning recirc off, windows closed and the right film on rear glass usually works. Am asking HVAC engineering to investigate.”
“@bryanclarke physics + a broad range of engineering. Worth taking humanities courses too, particularly history.”
“Anyone interested in doing ultra hardcore vehicle engineering at Tesla, please apply!”
