Rocket car

I have 2 pulse jets, They are jets, in that they need and burn air. A rocket has both fuel - solid or liquid - and the oxydiser so needs no air. Actually they work better in a vacuum.

Nitromethane is "almost" a monopropellant in chemical terms too. But once fuel and oxydiser are mixed and set solid it becomes a mono propellant! At least for our simple descriptive purposes. It may be a mixture but its still a monopropellant. Like a firework. They work without air etc.

Like the ones on the V1? They've got spring loaded flaps at the front so the fire goes the right way.

Are you thinking of a ram jet? (ah - there are non-valved pulse jets too, but the V1 is the one I think of normally).

cheers, clive

No, not at all. It's a homogeneous bipropellant. The chemistry is still the chemistry of a reaction between two things, even if you've physically mixed them.

But the normal usage of the terminology is solid fuel = both oxidiser and fuel are solid, hybrid = solid fuel with a liquid or gas oxidiser pushed through the fuel. You can argue that a hybrid is a solid fuel rocket if you want, but I think if you started going about calling hybrid rocket a solid fuel rocket, people would think you were a bit tapped.

Glad that we have someone posting to the group who appears to know what they are talking about!

I hope you are listening carefully. You might learn something.

Yes indeed, certainly makes a change after you posting s**te about it having been a rocket car :)

I'd class that as "old" not "tame".

Unless the engine is an Adour in which case it's old and tame despite the afterburner.

Everyone has something to learn, and I am certainly no exception.

Sorry, did it again; too many letters! "Overwhelming" basically means "too much".

Hope that helps.

Judging by his usage, I would say yes. He has a fair handle on the correct definition and conversational use.
