Round 2 of Sketch Madness is underway! Go to www.thatjoescott.com/madness to vote!
Chemical rockets have made it possible for us to launch satellites into orbit and land humans on the moon, but if we want to go further, into the solar system and beyond, we'll need a different kind of engine, and NASA has recently partnered with DARPA to build a new nuclear thermal propulsion engine named DRACO. If successful, it could change the trajectory of our future in space.

The nerva project had a 100% tested working engine, using this concept. That was more than 40 years ago so with modern updates. There's two ways the engine can produce thrust. Either cleanly with no radiation leakage or leaving a wake of fallout. Also without any oxygen on board for fuel the design is very stable in comparison. They should have been flying many years ago.

@THX..1138 Год назад

NERVA was shut down for political reasons, otherwise it was basically ready for space when the program ended...IDK if the DRACO timescale is really feasible, but chances are high most of the engineering hurtles were completed with NERVA. In fact I wouldn't be surprised if the DARCO engine is almost a direct copy of NERVA as the design was well proven. So 4 years for a working prototype may not be impossible.

Hey Joe, just a note on specific impulse. It's not a time, it just simplifies to seconds when you cancel all the units. It's a measure of how much impulse (momentum) the rocket's fluid delivers per unit mass.

@oeliamoya9796 Год назад

Yeah but it helps laymen understand a rocket's comparative performance. The ol' apples to apples while not getting into how some rockets are optimized for sea level or in a vacuum and to use a rocket outside of it's optimal altitude will drastically affect the rocket's designed specific impulse. (Which is why rocket's destined for space but launched from sea level have 2-3 stages)

The nuclear advantage do not have to be shortening travel time only. There are other important factors too like the mass of your cargo and overall mass of your transfer stage including propellant. So you can use this advantage for 3 things: 1. Shorter travel time with the same mass of cargo and the same transfer stage (as you described) 2. Decrease the mass of transfer stage with the same cargo and the same travel time (reducing the cost because there is less mass to lift into orbit) 3. Increase the mass of the cargo with the same transfer stage and the same travel time (so more stuff can be transferred into Mars with the same transfer stage)

Ive always been obsessed with this, since I was introduced to rocket & space craft thru military aviation / weapons (navy & USAF). The concept of cat-obar systems. As wright flyer an others where launched like that, an high altitude to gain speed / energy. The tech for electrical energy systems has never been in the same sweet spot chemical propellants. Super conductors are probably the limiting factor now. (Besides fusion or fission So what if we used this on towers or silos? What would we gain? VLS on subs (compared to surface ships) have neumatic / hydraulic assistance to gain critical inertial energy to be fired under water. The thing with navy cat-obar systems is that you have limited distance and can withstand high g launch. A space craft (shuttle for exampe was like 3g iirc) With a rocket/SC you need to handle the conditions usually increasing mass, ... An on an on. So staging makes sense. The concept of rail launched vehicles are no longer theoretically (impossible). We can use basic neumatic / electromagnetic systems to launch. ( But from the moon or low gravity/ atmosphere/or in vacuum) I think boring tunnels or sub sea tracks but the biggest issue I've been working at is. How to gain an advantage for rn cost an complexity don't support real invitation. Is getting a track long enough (horizontal) to slowing gain velocity, (not to much as SC are not designed for low supersonic flight. You would hit max q probably before lift of (if you have to pivot vertically ) Star ship is probly the best vehicles to try as the launcher / tower has catobar Esq methodology. An stronger / resilient chassis. I would not see why assistance in any sorts would be used . Hopefully we can see 747 b-1 / c-5 Galaxy/ B-52 b-21 with a rail launched vehicles of sorts. If you luck up Terran space academy he has plenty of videos going over this concept in detail an many others related to this an much much much more !

@mikedodger7898 Год назад

@Dizzy Izzie thank you for a long and reasonable response. You touched on a few options that seem reasonable, such as the boring tunnel. Also, even though the power conversion may not be as effective as chemical, can you address the many other mitigating benefits? Less chemical reactions should (I'm guessing here) is more environmentally friendly and more sustainable. Also, with a long acceleration distance (some mining tunnels are quite deep, such as the Kola Superdeep Borehole that is just over 40,000 feet deep, or over 12 km) so with an acceleration of 3g to achieve escape velocity on Earth (11.2 km/s) it would take 26 seconds to travel 10km. I probably have many things seeing with this evaluation, but this seems reasonable.

Just a reminder, if u burn to get a high speed to get somewhere, you'd have to burn almost the same amount of fuel to get slow down (of course u can use parachutes and atmosphere, but they either don't always exist or is not enough). So even if chemical rockets can get to as high speeds, they don't have enough SI to slow down from that high speed.

@codymoe4986 10 месяцев назад

I highly doubt "they" would burn more fuel than what "they" need to slow down/return home... "They" are rocket scientists...

@justaguy6216 10 месяцев назад

@@codymoe4986 It's not about returning home. Let's say you sent 500L of fuel to get to about 13 km/s from Earth's orbit to have a straight bee line towards mars. You'd need to burn almost the same amount of fuel to slow down from 13km/s. Hence you need an efficient engine to burn for a LONG time to be able to do this. Mars does have a thin atmosphere so a portion of the deceleration can be done by it, but nowhere near enough. That's why most missions to mars don't make a bee line towards mars they use a hohmann transfer or something very close to it to save on a lot of fuel and ISP.

He also said, due to radiation, that you wouldn't want to be near once of them when they were producing power.

I was told there is at least one NERVA engine boxed up at Hanford in working order where it was sent after the program was canceled.

Being familiar with the NERVA program I met NASA's announcement with a hearty, "Well DUH!' I've been waiting for them to dust that off. As for ambitious timeline if they were starting from scratch I'd be more skeptical. They have a good base to work from, and with modern computer modelling and manufacturing it might be less hopelessly optimistic than we think. It all comes down to funding; I think if they can throw enough money at it they might be able to do it.

Surely containing a fusion reaction efficiently and carefully extracting energy out of it *and* getting more net out is *harder* than "simply" setting of the same reaction and throwing particles out one direction for propulsion, right? If I had to guess, we will get The Expanse-style propulsion sooner than commercial/economical fusion power (but I'm not doubting commercial fusion power - I'm saying propulsion could be even closer)

What we need is an engine consisting of a mass accelerator powered by a nuclear electric generator. To start with we can use a simple nuclear thermoelectric generator, but we need a lot more power than that. A mass accelerator, same concept as a high-energy particle accelerator, will minimize the amount of propellant used. When more powerful generators become available we add accelerator channels. We will have a craft that continuously pulls one gee yet.
