5 Launch of a Handmade Aircraft

Launch of a Handmade Aircraft

Posted on June 21, 2011 by team

The space attracts all people with its mystery. And Russians are not an exception. During weekends some of them construct little aircrafts and launch them into the cosmos instead of ordinary walking or going to cinemas.

First of all, for the launching you need a weather balloon, or its analog – an old American military ball that was easier to get than a Russian balloon.  During the ascent the balloon is constantly widening  because of the decrease of atmospheric pressure, and at a certain height it will inevitably burst. The balloon may be filled with helium or hydrogen. Inert helium, unlike hydrogen, is safer, but hydrogen has to be used for record launchings because of its greater lifting capacity. The 40 liter container under pressure of 150 atmospheres contains 6 cubic meters of helium. One cubic meter has a lifting capacity of about 1.1kg. The more cubic meters of gas a balloon contains the more it can raise and the lower it bursts. By the way, it is important not to forget that the balloon weighs about 2 kg and this weight has also to be lifted.

    This is a pretty simple and easy to construct idea. It would be good for a school project. Reminds me of the Japanese balloon attacks on the US during WW2

    A. Bunka here. That is very very cool.

    A very creative way of getting high-altitude photos. I also liked the choice of 4x4s. Nissan Patrol and Land Rover.
