Project Team Leader and the completed Reusable Helium Balloon
Worlds Largest Reusable Helium
Balloon Completed by Canadian Manned Space Flight Team -TORONTO December
2, 2004: – The Golden Palace.com Space Program Powered
by the da Vinci Project announced today that it has completed
construction and flight qualification of the “Worlds Largest
Reusable Helium Balloon” for its planned manned flights to space.
The balloon will carry the projects Wild Fire MK VI manned spacecraft
to its launch altitude of 70,000 feet (21,340 meters).
The Balloon was built by the team throughout the late Summer,
Fall. “It’s an incredible achievement said Brian Feeney Team Leader
of The Golden Palace.com Space Program Powered by the da Vinci
Project. It follows years of research and development by
the team with input from some of the most talented balloon design
and fabrication people on the planet”.
At no time in the program did we think this was something that
could not be accomplished. “It was a monumental undertaking. After
all the design, engineering and testing we hunkered down and built
it said Steven Davies Balloon Production Team Leader”. “Following
months of preparation we turned out the final flight balloon using
production equipment built by the project”.
“It’s like everything else in this project said Brian Feeney,
we’ve overcome barrier after barrier driving toward our goal of
private manned space flight”. We’re definitely moving toward a
first flight as early as feasible in 2005”. The projects goal of
putting the first Canadian manned spacecraft into space and only
the second private team ever is sound. Getting down to it and engineering,
testing and building the largest reusable balloon ever is typical
of the day to day tasks face by the team. “This team is the most
tenacious forward thinking group of volunteers ever assembled.
The 4014 lb balloon made from 4.5 mil thick custom extruded polyethylene
sheets, measures 152.7 feet in diameter and 200 feet in length
fully inflated. The volume is 3,698,167 cubic feet (104,615 cubic
meters) with a near record gross lift capability of 15,270 lbs
During the summer the project successfully built and flew to
40,000 feet a smaller balloon scaled to simulate all the flight
stresses. In the lab test sections of the final balloon were stress
tested to 1200 psi, twice the expected maximum stress loads. Balloon
section stress tests were carried out over 12 to 24 hour periods,
greatly exceeding the actual balloon float time of 2 hours per
“We didn’t stop there says Brian Feeney. As a precursor to building
the final balloon, we constructed a second 100,000 cubic foot test
balloon. This enabled us to perfect the manufacturing process as
well as provide an additional large balloon for field launch testing.
We even micrometer tested the thickness of every 400 foot gore,
every 12 inches, to be sure the material was within specification”.
Several additional elements are engineered into the balloon design
and recovery system to achieve the full reusability needed for
multiple flights to space.
