Tornado research Nebelwerfer

A new approach

It remains a problem to collect data from inside a tornado's funnel, due to the extreme forces present there.

Ground-mounted instrumentation can only reveal a limited amount, and there is then the problem of deploying it in the tornado's path without the researcfhers joining their instrumentation in an unplanned flight.

Loftable probes picked up by the tornado funnel are limited in the size and mass of instrumentation they can carry.

Ideally, a rocket would be used, but the extreme wind velocity would tumble and possibly destroy a fin-stabilised rocket.

There is an alternative design <link>

The advantage of the Nebelwerfer 41 is that it has a very smooth casing and is spin-stabilised. This means that it is much more resistant to any wind force acting to deflect it than a conventional rocket, while sparing the instrument package the huge and destructive acceleration of an artillery shell.

The projectile would be constructed as lightly as possible consistent with maintaining structural integrity, possibly using a ceramic-lined aluminium casing for the propellant. The nozzles could be formed from the same ceramic. Since the propulsion jets are angled away from the body, the instrument package at the rear would require very little protection.

The projectile would be specified as low-impact cold fallout. Besides, so much stuff gets flung around by a tornado that a small thing like a nebelwerfer is just a drop in the ocean.

The launcher is a simple tube and the units are reasonably directional. They could be mounted in fixed positions, with automatic triggering and/or remote controls, or vehicle-mounted as multiple arrays.

15 cm Nebelwerfer 41 https://en.wikipedi...5_cm_Nebelwerfer_41
The name Nebelwerfer is best translated as "smoke thrower". [8th of 7, Nov 24 2015]

       At first I thought that this was an idea that 8th had dictated while having a stroke but it turns out that nebelwerfer is a worghhbbffnnns

       He said "nebelwerfer", hehehe.

       How many nebels did these things werf, in the course of WWII?

       "Almost five and a half million 15 cm rockets and six thousand launchers were manufactured over the course of the war."

       //Almost five and a half million 15 cm rockets//   

       They would have worked for the N-Prize. The rockets (according to that Wikipedia page) had their motors in the top, with exit nozzles part-way down the body.   

       Therefore, they could have been stacked, end to end.   

       So, you could have a stack of, say, 50 of these things; fire up the bottom-most 25 as a first stage, then ditch those and fire up the next 12, etc, all the way to orbital orbit.

       " as lightly as possible consistent with maitaining structural integrity "   

       How is structural integrity maitained ?   

       Or, to quote the source documentation, how do you reinforce steel ?

       Maybe you could just make the probes small light pods with little helicopter beanies on top to fly though the tornado and map the winds and measure wind speed and temperature and moisture. And radio 3d mapping all at the same time while wifi transmits the data to a receiver in a bunker.

       Will they find the blackbox? Will it be orange? And ve all ask ourzelves vefer zey vill ever vinn ze Nebel priz.

       Wouldn't the data get destroyed when the nebelwefer explodes?
mitxela, Nov 25 2015
  

       No, it's transmitted by radio while the unit is in flight.
