Airfoil vs. Flat Wings?

I built a model airplane which is rubber band powered. At first I built the wing of the shape of an airfoil and I can assure you that the shape was perfect. When I tested the plane, it just kept on going and going straight with very high speed but never took off. I guessed that the weight was more. So, after removing the weight it still didn't take off. I then used just a flat piece of cardboard for the wing with a slight tilt, so that it would deflect the air downward and produce the upward thrust. I then tested the plane, and even though the wing was heavier than the airfoil one and the plane moved on the ground slower than before maybe due to increased drag and weight.....the plane took off just beautifully just after a few seconds of launch!!! I don't know what was the reason, the airfoil shape was perfect, the surface area of the both wings was same. I guess that flat wings produce more lift.....I doubt that the airfoil produced any lift at all, or maybe they require significantly higher airflow over them than flat tilted wings to produce a fair amount of lift...can you tell me what could be the reason?

how to make flaming wings for photos, using spark plug, gasoline and pipe?

I wanted to create a fire effect using some type of combustible set up to simulate firey wings for various photographic projects. I thought maybe making a twin metal tube design out of copper with many little holes and a ignition tap with a gas reservoir. but have to think of how to ignite it safely, how much gas to use without being too dangerous and the proper expansion of the pilot holes. The ignition system should be something simple and reusable, probably a spark plug and battery system. anyone have any ideas or advice on how to do this? thanks.

How to create wings for human flight?

All of us have seen humans fly in those triangle shaped gliders. How about creating wings that will do the job? Understood that it requires more than wind to propel it so flapping power could be harnessed.  I need designs and the physics(i.e How much area of wing is required to lift what mass of body and etc.) Please suggest solutions ASAP!

Real-Life X-Wing Set to Fly

No, really.Andy Woerner and his crazy rocketeer friends have built a 21-foot long X-Wing model that can actually fly. Yes, this is a real X-Wing powered by four solid-fuel rocket engines complete with radio-controlled moving wings. It blasts off in California next week, and we talked with Andy about the project, and how they expect it will do. The X-Wing model is huge. At 21 feet long and with a wingspan of over 19 feet it is, in fact, big enough to fly a kid in. However, knowing that it will be powered by solid-fuel rockets, they wouldn't put a kid, dog, monkey or Gizmodo editor inside, even if it uses three full parachutes to land.After drawing the plans using CAD software, Andy's team and his friends at Polecat Aerospace (with the help of RMS Laser and Aerotech Consumer Aerospace) used laser cutting to make the pieces out of Baltic Birch wood. They also used solid aluminum for some parts, like the rods which are the pivot point for the wings. full story with more pics

How to install LED eyes on a wooden lawn deco bird and power it with wings that move and rotate with the wind? Answered

We have a flamingo bird, a wooden lawn ornament (of course), called a "Whirlygig" by some, whose wings rotate when the wind picks up. I would like to know if there is a way to harness the energy from the rotating action of the wings to power a couple of LED lights used as the eyes on the bird. When the wind picks up, the wings begin to rotate very fast and at the same time, the LED eyes would glow brightly. The body of the bird is a flat piece of 3/4 inch wood so a 9 v battery wouldn't fit well and would interfere with the rotating wings. Could the rotating wings accommodate some sort of dynamo effect to power the LED eyes? What about some bare copper wires glued to the inside of the wings and a magnet glued to the body? With the rotating wings and copper wires, wouldn't there be enough voltage to power a couple of LEDs? A solar panel would be nice but we want the eyes to light up at night when the wind picks up. Any ideas?

500 Lb Thrust small jet engine? Answered

So the fun and crazy side of me has come out again and I have thought up some crazy plans for a jet powered wing suit.  I'm sure many of you have seen the swedish rocket man, he jumps out of planes with a small wing and 4 miniature jets strapped to his back.  That is cool and all, but I would like to look at building something a little more useful than fun, although I could imagine it would be a blast.  The idea is to design a large wing 8-12 feet.  It will be made extremely light, however extremely strong because the wing should be able to handle strong g-forces, tight turns along with possible above mach speeds (probably pushing the boundaries of sanity.  This will probably require a carbon fiber and aluminum structure while requiring a rigid wing surface as apposed to the lighter plasticy flexible covering used by smaller aircraft.  This wing will be able to take off and land, eliminating the requirement of a plane to haul it up and then also not necessarily requiring a parachute (one will be worn at all times)  The wing I imagine will not be any lower that hip height and will also have a v-tail for more control.  Now my question is if anyone knows of a small jet engine that exists and would fit this project,  It would also be possible to fit two, one on the underside of each side.  I am looking for 500 to 1000 lbs of thrust and they need to be very small, and lightweight.  Do any engines of this type exist.  I also may be out of my mind expecting to take off with that amount of thrust,  I just don't imagine the whole thing to weigh more than 200 lbs plus me weighing just under 200 lbs.  So 500 would ideally allow for vertical take off, however it would probably not be practical.  Would an engine with this amount of thrust be suitable for my needs or would I need 1000 to 1500 lbs of thrust.  One big goal is for the wing to be very efficient so I don't want to be wasting fuel, however it would be nice to be able to fly quickly for some local entertainment.  Maybe I would throw on some solar panels for the electronics as well. EDIT....... I found this http://jetbeetle.com/JB_body_products.htm This engine seems pretty substantial, would one or two of these be capable of doing what is needed here?

How does the Bernoulli effect affect the ground effect?

I have been wondering about how ekronoplans work with consideration of the Bernoulli effect. Ekranoplans such as the Caspian Sea Monster often have there engines or propellers pointing on a downward angle, this is to push as much air under the wings as possible, in doing this they are forcing the air into a constriction being the wing and the ground, now why doesn't this cause a vacuum pulling the craft down?

Rotating Powered Display for GEEK swag

OK, Ill admit it, I'm a nerd.  I'm a Star Wars fan, and I got a new den that I want to geek out. I have a museum-quality X-wing fighter that I want to display on a counter top (&&&).  The piece has a display base, and a acrylic post that the model sits on - and through which three wires go up into the model and illuminates the outer engines, and numerous cockpit fiber-optic display bits.  It is uber-cool to look at in the dark. 8-) But I want to fab a custom display base that ROTATES so the model does a slow 360 revolution over, say, a minute or so.  But I also want to KEEP the lights. So, my puzzle is this.. How can I fab POWER RINGS, so that my model can display its lights as it revolves? -Or- Is there any way I can hack some kind of cheapo commercial wireless power conduction thing, so that I dont really NEED hard wires at all.  I can rig some rechargeable battery pack onto the rotating display base, and something that transmits the power on the table-top base (that doesnt rotate).  To be clear, the motor that does the rotation OF the base I can wire directly to the wall, But for the LEDs built into the model, I figure I need maybe 40mW of DC power that I want transferred to the batteries on the top to juice the model while turned on. I get this idea from my Wii wireless controller recharger.  I only have to put the controllers onto a special plate plugged in to the wall when not being used, and they recharge.  With this, SOMEHOW, power is getting to the batteries in the charger *without* being directly wired to the charging adapter. Anyway, since everyone on this site is a genius, I know the can give me an idea or two.

Noob Q about inverter for an ornithopter

I was looking in the back of my Jameco catalog the other day and they listed a product called "Muscle wire". It's apparently a nickel-titanium alloy that shrinks as it heats up. It occurred to me that I could flap ornithopter wings with it (a really small ornithopter). I was trying to figure out how I could switch voltage from one pair of wires (the flap UP wires) to the other pair of wires (the flap DOWN wires) without a microchip. I came up with something I'm sure wouldn't work involving a couple transistors, a diode and a cap. Today on wikipedia I figured out that what I was doing was something close to an inverter.So here's the question: Anyone know of a simple switching circuit that runs on a/c power and does not have square-wave switching characteristics?I'll keep researching this myself, but sometimes 'tis quicker to ask the big-brained and kind hearted (you know who you are).

555 timeout troubles?

Evening all,  This is most likely a very basic problem but for the life of me I can't find the solution. The project: auto folding wing mirrors (see below) http://www.lexusownersclub.co.uk/forum/index.php?app=core&module;=attach&section;=attach&attach;_id=6108 The problem: for some reason my alarm logic is the opposite way round, most likely due to the removal of my motion sensor due to it tripping my alarm when locked. Now I have modified the circuit shown in the PDF to remove TR2 and R4 so the I/P to the 555 is kept high by the 12v alarm signal. I have a pot between pin 2 and ground so I can adjust the pull down point as the alarm signal only drops to 9.7V and, obviously, the 555 needs logic high or low. So, having adjusted the pull down point, I find that the 5 second timeout, which worked when I first built the circuit as per the PDF, no longer switches the O/P off.  So so what am I doing wrong or is it just best to us a picaxe to do all of this as I code write up the code in half an hour or so. thanks

Robot Pegasus design possible? Answered

Ok, so I have another idea that will most likely never get anywhere due to my lack of funds/it not being possible.           What if I made a magnetic track somewhat like a maglev and had a robotic pegasus with electromagnets in its feet. It would also be an ornithopter to get it farther than a few inches off the ground. I would have the magnetic track to have it hover a few inches off the ground for about a minute before and after takeoff to make it less likely to crash on landing and give a minute to text the mayor to not worry about any upcoming pegasus sightings above or around town before taking off.           What kind of horsepower engine would I need to power the wings enough to get sufficient lift (at least 15-20 feet)? And would the electromagnet buffer before landing be significant enough to at least lessen the impact so it doesn't maim/kill you if you crash?           The electromagnets don't seem to me like they would work, but it would still be fun just to hover it to show it off without flying up 20-30 feet and worry about falling. Also, would it make it too heavy to fly if I put in an extra motor to make it walk/run so it doesn't have to be flying to move? I don't really expect this to be within my budget, but it would still be cool.

Record Solar Powered Flight

UK-built solar-powered plane has set an unofficial world endurance record for a flight by an unmanned aircraft.The Zephyr-6, as it is known, stayed aloft for more than three days, running through the night on batteries it had recharged in sunlight.The flight was a demonstration for the US military, which is looking for new types of technology to support its troops on the ground.Craft like Zephyr might make ideal platforms for reconnaissance.They could also be used to relay battlefield communications.Chris Kelleher, from UK defence and research firm QinetiQ, said Unmanned Aerial Vehicles (UAVs) offer advantages over traditional aircraft and even satellites."The principal advantage is persistence - that you would be there all the time," he told BBC News. "A satellite goes over the same part of the Earth twice a day - and one of those is at night - so it's only really getting a snapshot of activity. Zephyr would be watching all day." The latest flight was conducted at the US Army's Yuma Proving Ground in Arizona.The Zephyr flew non-stop for 82 hours, 37 minutes.That time beats the current official world record for unmanned flight set by the US robot plane Global Hawk - of 30 hours, 24 minutes - and even Zephyr's own previous best of 54 hours achieved last year.However, the Yuma mark remains "unofficial" because QinetiQ did not involve the FAI (Federation Aeronautique Internationale), the world air sports federation, which sanctions all record attempts.The US Department of Defense funded the demonstration flight under its Joint Capability Technology Demonstration (JCTD) programme. The 30kg Zephyr was guided by remote control to an operating altitude in excess of 18km (60,000ft), and then flown on autopilot and via satellite communication.It tested a communications payload weighing approximately 2kg.At first sight, the propeller-driven Zephyr looks to be just another model aircraft, and it is even launched by hand. But this "pilotless" vehicle with its 18-metre wingspan incorporates world-leading technologies.Its structure uses ultra-lightweight carbon-fibre material; and the plane flies on solar power generated by amorphous silicon solar arrays no thicker than sheets of paper. These are glued over the aircraft's wings.To get through the night, the propellers are powered from lithium-sulphur batteries which are topped up during the day."A lot of effort has gone into power storage and light-weighting the systems," explained Mr Kelleher. "Lithium sulphur is more than double the energy density of the best alternative technology which is lithium polymer batteries. The engineers from the Farnborough-based company are now collaborating with the American aerospace giant Boeing on a defence project codenamed Vulture.This would see the biggest plane in history take to the sky, powered by the sun and capable of carrying a 450-kilo (1,000lb) payload.US commanders say the design must be able to maintain its position over a particular spot on the Earth's surface uninterrupted for five years.
