I share the concern over the "start with a rifle" phenomena, and we do already have one and a half(filthy bread-eaters!) of the things, but a carbine for the cavalry and navy would be really very very convenient...
Ehh, stuff it, throw in an incendiary warhead and I am all over those rockets!
Half-tempted to take things way-too-far and suggest a recoiless rifle...
Maybe some rifling on the rockets themselves? Does anyone here have any rocketry knowledge that suggest that inducing spinning on an unguided rocket is a bad thing?
Fire Sparrow
A 30mm* rocket with external rifling and and an updated propellant mixture permitting it to fly without wings. It uses a simple payload of a lard and rice-alcohol mixture*** in a clay bottle
which is heated to combustion by a conductive rod running the length of the rocket**. It is launched from a reusable steel tube trailing a Y-shaped prong behind it and holding a crank-adjustable
bipod underneath for precise controls when braced against the ground, but can also be launched from an under-arm grip in emergencies.
* I intend something small, I assume that the crow is larger than 30mm and like the idea that we already produce 30mm tubes for our muskets, but ehh...
*** So, we could probably look into quicklime or phosphorus or something that would be more effective, but this should be sticky and flammable and patriotic. Also I want to try to be somewhat restrained somewhere in the design so it isn't completely insane)0-0(.
** Probably impossible to actually get this to work, the rocket propellant really isn't designed to work as a heating device. So I am mostly counting on enthusiasm to override sense...
)0-0( I am, of course, completely insane, so if this is to be taken seriously, someone else should formalise up an alternative!
