Aero-Dynamic Lubrication?

[akahenaton]

Are there any systems for Aerodynamic Lubrication?

LOL, I have heard of things resembling this concept. In underwater for example air bubbles swarming the submersible can reduce drag.

I did come up with an invention idea that is related here.

I wondered, if a person was do build a design correctly to create a plante that flies itself.

Lift is created by gaining speed through the air to create motion etc, and allow the air to pass over the wing structure to create the lifting effect etc...
Now, if one was to build such a plane where the engines were located in such a posistin that they provided substantial thrust of air over the fusilage even while the plane/flying machine was at rest relative to the ground, would it, could it fly, and even maybe hover?

For an example. If you take a plane and put it in a wind tunnel. And hold it from blowing backwards it will try to take off. Now, lets attatch a hypothetical engine that blows air through a vent to a high energy lifting wing structure of the fusilage and create some lift, and redirect the remaining air flow downwards to prevent undesired motion and add to the lift.

Whats the thoughts on this wild idea lol.

I'm not sure, but I believe that there are problems with laminar flow systems at high mach and certainly at ultra-sonic (mach 20 was mentioned above), both because of the the effect of heat on the surfaces not being able to maintain the tiny ribs (passive) and holes (active suction) necessary to create the laminar effect and the speed differential between the medium and the inducible vacuum sucking into the laminar holes. There's a ton of interesting research at NASA on this, and you could start here.

Whoosh!

arkain, you idea is startelingly similar to the system I've been working on for an RC plane I'm designing.

I missed the Mach 20 in all the EEEE's, moreover I didn't know about laminar flow breaking down at higher speeds. Fascinating Buffy; you know everything! Of course if GAHD is staying under the sound barrier with his model, a little micro-grooving might enhance performance.

The shh is out of wooshh...whoo,

GAHD, are going to ionize (if i am not mistaken, that is what russians were working on to reduce drag on their superhigh speed airplanes way back when, in the middle of the cold war) the air particles a few inches before the front of the plane to make the air tension sort of "break" before it actually hits the front surface of the plain?

I’m uncertain what akahenaton means by “aerodynamic lubrication”, but can guess at a couple of possibilities

• Lubricating fluid. The famous SR-71 used the fuel contained in its single-walled wings to redistribute heat from its hot leading edges to its cooler flat sections, allowing it to radiate frictional heat without melting its titanium leading edges. Due to this construction, the aircraft leaked fuel prior to flight, leading to one “cult myth” that this leakage was designed to persist during flight to produce evaporative cooling, another that it wetted the aircraft’s surfaces to make them “slicker”. Neither claim is true.
• Active aerodynamics. Several experimental aircraft have incorporated computer-controlled systems such as small movable panels and, pressure sensors, and air jets, to create a airfoil or other airframe component with less drag than its static shape would produce. It’s a promising technology, somewhat analogous to using mechanical vibration to reduce mechanical drag between surfaces.

Given that unmanned X-43 has reached nearly mach 10 in level flight, MACH 20!!! may not be as incredible a thought as it might seem at first glance.

No alex, nothing that far-out. More like redesign the harier. The exaust is in the wrong place!

i dont have any source other then my previous post, cuz this has been pretty secret information, but, it was that russians were developing the rechnology that will ionize the air about 2 meters in front of the plane thus decharging it before it hits the plane surface thus creating less friction and not melting all the special ceramic shielding... I heard that there were reports of Russian jets flying close to a border 16 times the speed of sound, and i beleive it was from some special on the science channel a long time ago...
but perhaps they were missusing information, the only real reference i found was this: http://www.astronautix.com/articles/energia.htm
which claims that 1/8 scale of Buran (russian shuttle that got launched from an airplane) weighing at 1400 kg was making suborbital flights at mach 16, so i first dont claim that russians did not succede in their ionizer development, and the flights were suborbital, so i dont claim mach 16 on an airplane, but i here deem it is probably possible, cuz it worked in suborbit almost 20 years ago...
