China Missile Tech

It's basically the Russian hypercapitating torpedo but they intend it through the air.

Another way to look at it is they make bow shock on purpose. Bow shock is what happens to spaceships returning as well. It's actually exploited to require less heat shield on vehicles such as SpaceX starship and most space capsules. Basically as the vehicle hits the atmosphere it's going so fast that the air in front of it can't get out of the way. It ends up creating a little compression bubble and keeping the heat off of The Craft.

China intends the opposite if I understand correctly. Basically boil the air away with an ir lazer to reduce drag on the top.

This is the de facto illustration for explaining pressure on atmospheric reentry. But if you're trying to reduce trade it still applies. The laser in theory gives you the triangular shape but projected forward


Where the two concepts come together is this basically ends up forming a boundary layer bubble around and projected in front of the missile.Which should reduce the friction through the air.

I woudnt doubt their main problem is how the fuck do you power said laser without making a significantly larger vehicle. Followed by the secondary problem of flight control sans usual control surfaces. Which leaves something like rcs ports, spacex like fins or maybe something like a gimbled lazer on the front.

The theory on the last bit is choose where the air vaporizes in front to steer it.

Regardless of the specifics its a neat concept.

I wonder if this will actually be applied to submarines or torpedoes as well.

The other potentially nasty part of this is what happens to radio waves or radar waves when they encounter plasma? Off to Google radar return from plasma cloud.

Aka what does this do to our ability to sense an incoming plane or missile

The bad in detection:

So yes it does slightly make them harder to detect. 

The good in detection 

Although I would bet that today's phased array antennas and sensing systems could detect the plasma itself. But now I'm off in the land of speculation.

I do know  know there's also been a lot of developments in optical sensors and terahertz rf tech. I'm guessing it's well within the capabilities of today's military to detect the plasma cloud but I wouldn't expect anybody to give you a straight answer on that.

if they can do it with silicon they can definitely do it with geranium.

Lawn Tractor Snow Plow Electric Upgrade

Do you have a lawn tractor you use to plow snow? Ever wondered if you could make a manual snow plow attachment into a push button? A friend of mine had a riding lawn mower and snow plow blade attachment. Every winter he used the riding lawn mower to plow the driveway. The plow was a kit that bolted on the front of the lawn tractor and it had a mechanicaly actuated adjustable snow plow blade. The issue and this project came about when the arm to adjust the snow plow blade broke. I had just bought a mig welder. I had also watched linear actuators capable of handling 300lbs of force drop to $25 on ebay.  Here's what I came up with for converting a riding lawn mower snow plow into an electricity adjusted lawn tractor plow. Repair  The lawn tractor snow plow kit had seen better days. The fork that attaches it had bent /deflected and spread. I used a map gas torch and a bench vise to squeeze the tongs back and then welded some L channel angle iron on the sides. Less Play I also tack weld

CD Resistance Spot Welder

This post is for anyone interested in owning or building a CD welder. I wanted a reliable Resistive spot welder for lithium ion pack construction and or repair. I didn't want to spend 3k or buy from china. I decided to design and fabricate my own. Bellow is my first crack at a Mosfet Switched capacitive discharge mcu controlled spot welder. This post is a work in progress. If you've stumbled across in hoping to build your own cd welder feel free to ask questions in the comments section.  I'll provide any help I can.  My CD Spot Welder  Here's pics of the first working version from 2018
