Can we fire a magnetic pulse at a fighter ? |
It can be done with a nuke . However can the energy required
be cut down by directing it at a flying jet fighter say at 30,000 ft?
On discovery channel it showed model helicopters falling out
of the sky in an instant when near a big impulse of magnetic power.

Well, other than you can't direct a magnetic field like an
electromagnetic and fighters don't normally fly at 30,000 feet...
On discovery channel it showed model helicopters falling out
of the sky in an instant when near a big impulse of magnetic power.
Model helicopters fly because of consumer grade electronics to
stabilize them. It is trivial to cause consumer grade electronics
to fail with EMI.
Prior to the invention of small gyro systems to keep them stable in
around 1970, model helicopters were nearly impossible to fly at all.
Real aircraft are totally different.

Is a gyro system really required? We got a helicopter
(a rather silly foam affair) with dual motors, a small
battery pack, and a tiltable (though not controllable)
top rotor. (The company is a recruiting firm and one has
to contact them for the remote control. Cute come-on.)
There's a jack for a power eliminator, presumably to charge
the battery pack, and a sticker declaring "49 MHz".
I don't expect it to fly forward all that well but it
should go up and down and spin (the second motor is hooked
to a tail rotor, though there's a nasty kink in the cable
that will probably allow it to vibrate itself silly).
How big would a gyro system need to be for such a model craft?
(Dimensions from nose to tail is about 15 inches or so; I've
not measured it though. Hard to say what the actual weight is
but it's not all that heavy.)
Real aircraft are totally different.
Aye! :-) For starters, the top rotor doesn't have plastic
"protector ringlets". :-)
Some of the newer models are interesting. Instead of the traditional
tail rotor they either direct the jet sideways (which will tend to
push the whole affair sideways but does compensate for torque) or
they put a cowling around the tail rotor, presumably to keep it from
getting stuck in the trees and crashing the craft.

Try to hover. Even landing will be more of a controlled crash than
a realistic landing.
A real RC helicopter will just hover with no control input once it is
trimmed out.
The gyros are really small. Google RC helicopters.
Back in the early 70's a friend of a friend was an ME with the obsession
to make RC helicopters fly like real helicopters. He and a group of
like minded people were the ones that came up with all the trick stuff
that makes it work. Beer and ***** sessions...

On real helicopters the cowling around the tail rotor is mostly for
aerodynamics. Notice that real helicopters have vertical stabilizers
which reduce the need for tail rotor force to compensate for torque
and to do turns at cruise.

I wouldn't know; we've not had it in the air. :-) Interesting,
nonetheless.
I used to hang around with a bunch in the early 80's during
my college days who flew model aircraft (most of them used
gasoline or diesel, if memory serves; one of them was a
modified glider). No helicopters, though.

I guess that MEMS accelerometers beats out an optical gyro, (sagnac), in
the short term.

These days micro accelerators are used in the most unexpected places.
There is a new game console, Nintendo wii, that has a remote with a 3 axis
sensor, so if you wave the remote, then the character on screen moves with it,
no buttons to press for direction:
http://wii.nintendo.com/controller.html
It uses this sensor:
http://www.analog.com/en/prod/0,2877,ADXL330,00.html
All this requires you to design some electronics, the advantage of using the
Graupner connection system (as in http://www.hobby-lobby.com/gyros.htm ) is
that you can simply add it in a 'chain'.
That system uses standard RC servos, these servos go to mid-position for
a 150ms pulse, <150 ms takes them one way, >150 ms the other.
When no pulses are present the servo stays in the last position.
Nice in case of a bad radio link...
So when you have for example tail rotor speed control, it is very
difficult to make the speed so the heli points in _one_ direction and
_keeps_ pointing in that direction, it will tend to rotate around one
way or the other.
When you add such a module and align it to detect rotation in the
horizontal plane, then it will supply a pulse width in such a way that
it stays aligned in the same direction....
But not only for helis, for example I have designed a small camera
position control, it directly interfaces to several servos, x, y...
Open source: http://panteltje.com/panteltje/pic/camc_pic/index.html
If you were on a war ship, and ships are _never_ steady, and wanted to
make a movie of a missile coming in... you could add such a sensor unit
to for example the x and y control.. just by plugging in.
And no matter how the sea was, the camera would stay put...
Same for a platform with a missile launcher of course.
Maybe some guys at Hezbolla will read that first prize too, and maybe
even have, the Internet police will jam into action (jam the right word? ;-) )
and no more model airplanes...... no more Nintendo Wii.. solder out
the sensor.... LOL
All technology can be used for the good and the bad, and the good is what
the winner defines.
I knew I should not have posted today, well, aiming at the white house
(see ) was not a bad idea in retrospect:
http://groups.google.com/group/sci.electronics.design/browse_frm/thread/15b0121e495ba0dd/62de3091d4d68156?lnk=gst&q=panteltje+V2+&rnum=2#62de3091d4d68156
I also looked up the word 'Serendipiy', and the associated stories.
I conclude that I live and design by 'serendipity'....
Or rather use what you get or collected on the way... use things in unexpected
ways in unexpected places...

The army has a small unmanned track vehicle with a rifle. It really

BTW, I couldn't see anything with ME.

Yea, I want to use the msp430 for heating control. Most of the money
goes into military it seems. Every publication now asks me if I do
military electronics now.
BTW, how do you like the PIC Development system? I have tools for the
hc11, but it is old and the msp430 looks so easy. (Easy is part of their
promo). I figured I couldn't go too wrong with the $20 starter kit.
I don't want to make a career of developing a microcontroller, it is
just part of a bigger project.
I'll cross this to sci.electronics.design and join that group.

'Sensitive to GPS jamming....', OK, nice, but we see again and again
that low tech guerilla tactics sometimes are more effective.
Good surface to air missiles, dispersed under civilian population.
anti tank... I dunno, I would _not_ put too much faith in high tech.
Maybe US will one day go 100% high-tech, rely on GPS and sat communications
100%, enemy shoots down or takes control of some mil satellites,
and US has lost a war?
A missile to bring down a sat is not _that_ a big deal, especially if
the sat is transmitting towards the battle field, just head for the
transmitter.
Maybe I am dreaming, but sats are expensive and expensive to launch,
so it may be worth the cost of such a missile.

Nice price $5.50@1k.
All this requires you to design some electronics, the advantage of using the
Graupner connection system (as in http://www.hobby-lobby.com/gyros.htm ) is
that you can simply add it in a 'chain'.
When I was a kid RC stuff used vacuum tubes. They have come a long way.
Oh yes, they have come a _very_ long way.
The army has a small unmanned track vehicle with a rifle. It really
bounces around while moving. I'm sure that is what they do for the
travel view.
BTW, I couldn't see anything with ME.
? My site? cameras are elsewhere atm...
Yea, I want to use the msp430 for heating control. Most of the money
goes into military it seems. Every publication now asks me if I do
military electronics now.
I have no experience with that chip, any micro should do for heating
control, even did it with a 8052.
BTW, how do you like the PIC Development system? I have tools for the
hc11, but it is old and the msp430 looks so easy. (Easy is part of their
promo). I figured I couldn't go too wrong with the $20 starter kit.
Well, I have MP lab, and I never use it.
I use Linux and picasm.... I never use a debugger, I wrote loads of software,
even a complete OS, a multitasking OS too, no debugger, only an oscilloscope
:-) to see if what I wrote worked.
Same for asm, C, etc.
noppp_lx as programmer..... just added code for the other PICs I use.
There is also gpasm gputils, several other pic open source packages for Linux.
MP lab is big, I think I borrowed some headers from it......
No GUI for me, just an xterm or 9..
Software is rather deterministic, if you keep some simple rules and know
how the hardware works, no need for debugger..... You can see what you did
wrong.
But how many people these days can write 100 lines of ASM that work first
time?
Hell MP lab and some other soft allows you to simulate your code....
How tyring.... Only a few instructions for a PIC, just get some basic
function working, make some asm libs for yourself..... and you are good to go.
I never simulate anything in PIC, just write the code, use a pin as test out,
get the subroutines or whatever working, connect it all together that is it.
Faster cheaper better.
I know many people do thing differently, for those:
<insert flames here>
<end flames>
I don't want to make a career of developing a micro controller, it is
just part of a bigger project.
I can only recommend the PICs, specially as Microchip has one for about
every application you can think of.
If you run out of speed use an FPGA.
I'll cross this to sci.electronics.design and join that group.
Best, Dan.
OK

On discovery channel it showed model helicopters falling out

A phased array of explosive EMP generators?

Short answer yes.
Directed energy weapons have been under development for a very long
time. Some of their experiments or trials have had disastrous results.
They are effective but are some ways from implementation.
This is all available by digging in public sources.

That's a damning indictment of Discovery Channel.
Do you believe everything you see on TeeeeVeeee ?
