    Pressure and temperature of water boiling in a heated container with a small hole

    I'm trying to build a mathematical model of something like Heron's Aeolipile: http://en.wikipedia.org/wiki/Aeolipile I'd like to know, based on a known heat flux, the pressure and temperature attained in the container. I assume as water boils, the control volume loses mass and energy, the...

    Garage Built Project

    I think the Icarus glider was featured in that movie where the girl flies an ultralight to lead geese in their migration. Her dad flew one into a tree if I remember correctly. I would say that something like that, a tube structrure and no engine is easy to build by amateurs...

    Human Powered Aircraft

    Will there ever be a marketable HPA? One that you can carry in your car/truck, bring it to a field and start flying on a nice calm day? Imagine how much cheaper and more accesible that would be than any powered aircraft or air-towed glider! I have some ideas on a radical VTOL HPA design but no...

    How to relate 2D airfoil Cd to 3D wing Cd

    I remember for an ideal wing it being around CL3D=0.9 CL2D? _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com

    you'll need an A&P license to work as a mechanic... _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com

    zero lift and induced drag

    for an entire aircraft, you will always have some form of induced drag, because you have to factor in the control surfaces which generate their own lift :) _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com

    Advice for new grad wanting to eventually be self employed

    I'd like to start a business somehow related to engineering and computers hopefully in my early 30s...or sooner. I'm gainfully employed right now but I'd like to be my own boss and work doing something I really feel close to. And have the freedom to do what I want when I want to. Hopefully it...

    Easy to be hired being a Foreign National?

    yeah, forgot to mention the OPT (optional practical training) year...which can lead to an H1B visa. _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com

    Easy to be hired being a Foreign National?

    Lumens, are there any companies from your home country operating in the US, or any large companies where knowing a foreign language (yours) might be useful? Also, you could try looking into a Masters degree in Engineering. You will probably be able to secure an assistantship,which will pay for...

    Knife edge

    to avoid a knife edge, you need to dimple the skins under the head of the countersunk fastener. _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com

    Modern jets scaled versions

    I don't know about the F18, but the F16 is fly by wire. You couldn't fly that plane with direct linked controls because it is very unstable. So scratch the F16. Say you went and built a scale F4, how would you learn to fly it? You'd have to first train in a swept wing jet trainer like the T38...

    Easy to be hired being a Foreign National?

    get married ASAP. without a green card, you are subjected to export regulations which prevent you from getting most jobs at big aerospace companies that are in any way related to defense. Not married, you require a work visa. to get a work visa, you need sponsorship, for which the smaller...

    NASA's constellation program

    Main point is, space can be accessed cheaper than what you are lead to believe by the current space program run by the military-industrial complex & NASA. _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com

    NASA's constellation program

    if Von Braun got on the boat, I'm sure OTRAG had some promise, even if it could be a case of him wanting to help a fellow German and promote a renaissance of German rocketry....btw I am not German :) _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com

    NASA's constellation program

    I'm not advocating a nuclear launcher. A nuclear engine should be spaceborne. There are methods to reduce the price of access to LEO which for some reason were never undertaken by the military-industrial complex, probably because they were interested in maintaining the status-quo of expensive...

    NASA's constellation program

    VSE is not going to get us to Mars. The technology for a safe, reasonably fast interplanetary trip is not chemical rockets. As long as nuclear rockets are not developed, along with a cheap launcher to put them in LEO, we are stuck in the cislunar universe...

    Reducing Induced Drag

    if I remember correctly, the tip chord should be around 0.9 of the root chord on a straight wing to best approximate an elliptical shape. _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com

    yes, it's hectobars. they use that a lot for some reason in Europe. _______________________________________ Scientific/Engineering Code Exchange: www.solvengineer.com
