Why not put a generator inlet on the outside of the house and just get a normal (m -> f) power cable.

Good info, but it's too risky for the expensive Cybertruck. If you want to avoid the installation labor cost, consider getting the Powershare equipment and installing it yourself if possible. Doing it the right way will save lives and protect your Cybertruck from potential risks.

From what I'm hearing, one of the rocket engines malfunctioned (burn through). If not for the engine - which cannot be tested beforehand - the rocket probably would have flown just fine. It did lift off, so 'well done' to the team.

I have installed a generator inlet and interlock kit (see Amazon) and it was no more difficult than your 240V socket installation on the side of your house. Advantages - No widowmaker cable and no chance of back feeding the grid. If you have solar be sure to turn it off before connecting the truck.

Nice video, can you provide the link for male to male 240 volts Nema 14-50 cord you are using? So this works without all the requirements from Tesla as stated below TESLA - You need to have the Tesla Universal Wall Connector with Powershare Gateway installed in your home.

As a professional electrician, i would recommend you install a manual transfer switch with a 50a inlet. It is more exensive than a panel interlock kit, but it saves wear on your main breaker. I never turn a main breaker off, because when they are older, they will sometimes turn off and never turn back on. Do not use a widowmaker plug, and do not operate a backup generator (or in this case your cybertruck) without an interlock that prevents backfeeding the power grid. Peoples lives are more important than your convenience/not wanting to spend a few hundred bucks.

Hello. I am currently working on similar cold gas thruster systems as you did on my collage robotic team. -Which source did you use to design your nozzle diameters and what was your pipe diameter? -How big was your tank? Like how many liters did it have? And what was its pressure output. -What was the value of your initial pressure at the nozzle and did you use any regulators to reduce the initial pressure of the tank?

I think achieving thrust high enough to rip apart your test stand is a task failed successfully. Also, is that a TVC mount I see there?

@EvanLangphysicslang 2 жыл бұрын

You are right. This was one of the highest thrust level test I ran to date when it came apart. That is a TVC mount. This was a static test but here is a link to the TVC test. Large gap in content right now. Completely redesign parts and starting to use the flight hardware. Getting parts machined is talking a lot of time. kzbin.info/www/bejne/d3XHhq2fnZmroZI

How do you design a nozzle for a cold gas thruster?

@EvanLangphysicslang 2 жыл бұрын

Using the same equations and design for a normal rocket engine. It all starts with Isp, Mass flow, Thrust. Then you need to calculate all the other parameters.

@mrorange5881 2 жыл бұрын

How do you calculate thrust exactly when working with cold gas thrusters

@EvanLangphysicslang 2 жыл бұрын

Thrust is where it all starts. You pick a thrust, in this case, 50lb. Then you know the theoretical specific impulse for the gas you are using. In this case ~70s. Then you calculate the necessary mass flow. Once you know these three variables you start going through the rest of the rocket engine equations to obtain things such as your throat and nozzle exit diameters. Then you can calculate your plumbing sizes and what it will take to get the gas to flow at those Mass rates. During these tests I am measuring force with a load cell on the test stand. Log that data at 1kHz during the test.
