The tetroon balloon
For a personal project
that we have to present for the baccalaureate exam, we got interested in
solar balloons for his economical and ecological aspect. What is a solar
balloon? It is a balloon whose envelope is made of a black plastic sheeting
absorbing most of the solar radiations.
To spare
time and for practical reasons we choose to build a tetrahedron that is cut
out in only one piece.
Taking into account the plastics we used, the line of our tetrahedron is
5.77m long, so its volume V is 22,7m3.
What is the
mass lifted by
a given balloon?
How could we optimize
this lifted mass? Origin and quality of the radiation
