Videos of Cybertruck towing SpaceX rocket engine!! 🦾

Sorry to say, but I think that's actually a giant bbq and they rounded up all the chickens so we would stop measuring their truck.

What i actually think this is is a leak that is hinting at the CT getting a rocket booster add option. At 270 tons of thrust and the right angle, you surely can achieve flight.

Are you trying to be funny or just becoming a troll?

RIP shoulder.

I'm not sure I want to be behind a Raptor. Did you see what it did to the concrete?

What concrete?..... get it?

CAUTION: WORTHLESS INFORMATION CALCULATED QUICKLY WITH A VERY JET LAGGED BRAIN. (Sorry if I didn’t carry the 1 or something)

So for fun (yeah, I’m a nerd) I looked at public data on the Raptor3 engine. The weight of the Raptor2 has been reported at 3,500# of weight. the R3 thrust has been demonstrated (so far) at 590,000# thrust at SL. If we assume the trailer (as mentioned above) is ~2K# as well as the cradle, and a ~7k# CT, and fill the bed with 3,500# of fuel (good for 2.5 seconds of 100% thrust) would give you almost 33Gs of acceleration. Now, provided you could figure out a way to not shred the CT and its occupants apart and kill any living being inside, and not accounting for aerodynamic drag (cuz I don’t have a reliable cd, and at these numbers, who cares) you are looking at a speed of somewhere around 1750+mph. All in 2.5 seconds. Mach 2.33 in a standard atmosphere. Which looked pretty close to that video of the CT pulling away at the light.

I don’t think it matters if you are in front or behind the engine at that point.

At that point you don't even need wings. You could probably control the pitch by just accelerating or stepping on the brakes, the roll by leaning left or right and the yaw by opening a window. Done. you have a flying truck. probably want solid fuel source to prevent sloshing around.

If you scrub the video quickly forward and backward just after the 12:00 mark you can get a great sense on range of travel for air suspension. Goes from lifted high to pretty low fairly quick.

Great catch. Looks like nine seconds or so from high to low.

I always liked the SABRE powered Skylon concept, and have always wondered if there's less if a brute force method of getting to orbit.

I’m waiting for Kerbal 2.0 to come out for the Mac, I’ve got enough Mac horsepower at the house to really do something with it.

Skylon and Sabre are an interesting concept. SSTO is the holy grail right now. But there are massive hurdles in the way. I was involved with the X-31 NASP for a while, I’ve seen enough and done enough to realize someone is going to need to come up with a stroke of genius to solve the issues we are facing. The laws of physics are a real bee-otch, there is just no way around them.

That being said, I’m reminded of a discussion Elon had about the Starship. In explaining what the Starship could do for the costs of going to space (and the beauty of the Falcon booster) he said; “Imagine what an airline ticket would cost if the planes could only be used for one flight, and then they were done.” And then you could see the wheels turning in his mind. He then said; “There’s no reason Starship couldn’t fly from the US to like, Singapore as a regular service in about 45 minutes.” And he quickly changed the subject. Think on that for a moment…

There are hundreds of trucks at the work site.

The amount of pollution from Starship doing that would be pretty horrendous and might max out our budget for orbital flights. I would hate to see a world tinged in smog from reentry plasma.

Most trucks can tow just about anything off public streets. EV vehicles even more. Just limited by hitch capacity and low speed steering and stopping control, but judging by the trailer tires I doubt it weighs more than 14,000 lbs.

Actually many EVs out there actually tow less than their ICE compatriots. While EVs have high immediate motor torque, ICE vehicles may have more wheel torque due to gearing. They can also ride a clutch to get things moving on an incline. Of course you could slap a low range gearbox to an EV but manufacturers seem reluctant to do that.

I’m going to take it that you have never been around a launch site, or been around really expensive, really large, really heavy stuff being moved around.

When a satellite is being loaded on a plane there are at least half a dozen trucks involved. Only 1 is doing the actual towing, but you’ve got trucks on the side, behind, in front, all on the radio keeping an eye on the payload, the road, dogs running around (heard that once!) everything is watched. I have no doubt this was the same thing. The CT driver was being flooded with information so that they could move that very valuable asset safely. Ever notice a true wide load on the freeway? See all the extra trucks around it? They aren’t there in case the Semi takes a dump!

This is just all kinds of wrong.
