Wondered why NASA wanted to borrow my old Honda SS50... never did get it back
That thing was a real head turner... did have a small backfire issue though. But had no mirrors so i couldn't see what was going on ____________________ A2 Passed 18/6/10 |

google thrust in to hp,
regardless of a moving rocket, which you can get a hp measurement from (weight speed etc) if something doesn't move, its not doing any work (from a physics point of view)
if its not doing any work, then there is no hp/kw value
it does how ever have a inertia value, much like a rock sitting on the ground does
i didnt make up the laws of physics
you could say "what a potential 22 million hp looks like" ____________________ the humans are dead

If you listen to the voiceover, he actually notes that all the sand heaped around the firing area will have been turned to glass. Presumably passing briefly through a stage of being really soft sandstone...
The "no movement = no horsepower" point would be valid, if we were thinking purely in terms of the metal part of the rocket as a whole, as if it were an electric motor or petrol engine. If they don't turn, then regardless of the internal forces, they are generating no motive power (though there's probably plenty of thermal power being dissipated, which is not really the same thing, but one can be converted into the other and is measured using the same units).
However in this case, there IS stuff moving. The rocket exhaust. The rocket motor has no moving parts other than its outer shell, the burning rocket fuel, and the exhaust. It is propelled into the sky by the newtonian laws of thermodynamics, the burning fuel exerting force in all directions but only having one escape route. So it shoots out the bottom, and pushes the rocket upwards (at a much lower speed, at least at first, as it is heavy; but eventually much faster as the drag forces on the rocket are much lower than on the exhaust gas).
Now bring the rocket onto the ground and fasten it very securely to the landscape, then light it. It does not move, but the exhaust gas still does. It shoots out the back the same as before, but the portion of it's exerted force that would otherwise have gone into moving the rocket along is instead donated to its own momentum. So it blasts out the back slightly faster than it otherwise might have done, with an instantaneous dissipated power of almost 30 million watts... of which an unknown amount is heat, and light, and noise...
If you put your bike on a dyno, the body of the machine doesn't go anywhere, but the engine is still generating and using power (the pistons are going up and down, the crank and cam are spinning, air is being pumped in and exhaust is being pumped out), which is being transmitted to the wheel (gearbox input, output shafts, final reduction, chain and sprockets in motion), and that wheel is producing a certain amount of power in order to spin the roller against the drag of the dynamo (electrical generator) inside the dynamometer.
The engine and transmission through to the wheel are very close analogues, in this case, for the burning rocket fuel. Right down to how the engine will spin the wheel somewhat faster than what is actually attainable on the road, if it is allowed to rev that far.
Also: WHOOOOAAAAAAAAAAA DUUUUUUUDE
Why do we bother with diggers, TNT and borers when we could just mine for things or cut tunnels in mere minutes by this method? |
