How fast will the Tesla Roadster be? How do the Tesla Roadster cold gas thrusters work? How much will the Tesla Roadster weigh? What will the Tesla Roadster's 0-60 be? How about braking distance, or cornering grip? Will the Tesla Roadster be able to fly? Using everything that's been stated about the Tesla Roadster Space X Thruster package, we'll deep dive into how the system works and what sort of performance metrics you can expect to see as a result.
The Tesla Roadster will use an electric air pump, powered by the main battery, to compress air into a composite over-wrapped pressure vessel (COPV). The COPV will deliver highly compressed air (~10,000 PSI) to around 10 cold gas thrusters integrated around the vehicle. This cold gas thrusters will allow for incredible acceleration, braking, cornering, and potentially even the ability to fly.

    This is merely a distraction. Who really will drive like this? Perhaps as a stunt. The more practical matter with EVs is they cannot sustain high speeds for any sort of distance and hence will never compete in Le Mann or Dakar rally or any distance race until such time as they can have much shorter recharge times. I will be much more interested to get a rocket fast charge time, so I don't have to twiddle my thumbs an hour while my one ton battery recharges. Then maybe I can take a Roadster and race it in a real race against ICE/hybrids and compete.

    Your math could be flawed. Unfortunately this will require a little Aeronautical Engineering and the understanding of ground effect. It will take much less Force to lift the car then you have calculated. This is due to the "ground effect." Think of a Hovercraft. I e the thrust as much less than you have calculated. I have 15 years in the aeronautical industry. You must calculate for ground effect to get the correct thrust

    The truth is they can pretty much get it to accelerate as fast as they damn well please. It's just a tradeoff of boost time vs boost thrust. Air at 10,000 psi has a density of ~830 kg/m^3. A 500 L tank would be huge so assume ~400 kg of air onboard. Choked flow comes out around 300 m/s. So they have ~60m/s of delta-v onboard. Use it fast or use it slow.

  • Bill Kong
    Bill Kong16 dager siden

    700 m/s Isp is very optimistic. Gas generally can't be supersonic in itself. And adiabatic cooling means the exhaust from a 10,000 psi to RT decompression is going to be mega cold. 70s probably requires some amount of heating.

    Although it, in theory, could lift itself up, not all of that power would be useable in the acceleration, only 40% would, looking at the proposed number of thrusters. Cornering wise, I suppose you would only need to use the extra push if you went over the limit part way around the corner.

    So this thing should weight almost exactly the same as the bugati chiron which dose 0-60 in 2.4 seconds and the tesla dose it in 1.9 so its safe to say this car should have at least 1500 hp

  • Brendan Divall
    Brendan DivallMåned siden

    Thanks for the explanation, but why have you not considered that the 0-60 time of 1.9 seconds is with the rockets employed? Unless you can get the coefficient of tyre/tarmac friction above 1.0 (necessitating ultra sticky tyres & tarmac, and/or downforce) the calculated minimum time would be ca. 2.8s

    Air at 10,000 psi is about 32 lb/ft^3. Assuming you use a regulator and design the nozzle to work most efficiently at say 2,000 psi you can run the rockets until the tank pressure is 2,000 psi. Air at 2,000 psi has a density of about 10 lb/ft^3. Assuming a 0.25 m^3 (9 ft^3) tank and converting to metric you have 130 kg of air at 10,000 psi and 40 kg of air at 2,000 psi, so you can do the rocket boost for up to 3 seconds. Theoretically, they could use larger nozzles and exhaust the air in 1/3 the time and give you way higher thrust. I bet this thing could do 0-60 faster than a top fuel dragster if they wanted to. Obviously you wouldn't want to put the average human through more than say 3g's for health reasons but technically 6g's or more is possible for a human to withstand. I can't wait to see this thing in action. I've been in a model S P90D and even that was kinda uncomfortable for me during a 0-60 due to the g-force. It would take some getting used to.

    @PhotoGeorge No Kool-Aid. The physics works and they have the means to do it, so I am hopeful it will happen and be as cool as can be. Tesla makes fun products.

    Are we assuming the 1.9s to 60mph doesn’t include the thrust from the rocket? It’s hard to imagine a car accelerating to 60mph in 1.1s, it would be incredible to witness. I also had another thought. When the pump is sucking in air, could that be used to suck the car to the road? A bit like the F1 Fan car.

    The acceleration isn't limited by torque, it's limited by tire grip. You can't realistically work out the weight without knowning the tire details. Also, the range increase comes from a lighter car and significantly better aerodynamics, not just a bigger and more efficient battery. It's likely to weigh around 1800kg judging by competitor's cars.

  • Michael Kangas

    I think that the calculation of the wheel-based acceleration is suspect. Just because the wheel torque can produce a certain force at the wheel's surface doesn't mean that all of that force is available for acceleration: it's going to be friction-limited. Justifying an acceleration greater than g would require factoring in aerodynamically generated normal forces.

    Problem at 11:45, You just made the assumption that the *number* of rockets pointing out the back are the same as the number of rockets pointing down, as though there is only ONE pointing down when clearly that would not be the case, you would need to divide by the number of rockets pointing down to determine what it is for one rocket then multiply by the number pointing out the back [and that is assuming all thrusters are the same].
