Project Title:
High Temperature Polymeric Venusian Research Balloons
94-1 09.13 3200
High Temperature Polymeric Venusian Research Balloons
Abstract:
Exploring the lower atmosphere of Venus with a nonmetallic research
balloon can be achieved with a new generation of high temperature,
liquid crystal polymeric materials. Foster-Miller will develop and
evaluate two balloon materials for use in the lower Venusian
atmosphere. We will use our extensive experience in the extrusion
of liquid crystal polymer films to produce an LCP film with optimal
orientation for a lightweight, high strength balloon material. In
addition, a fabrication procedure will be developed to produce a
novel fiber-reinforced, high temperature, liquid crystal
polymer/polyimide balloon material. Through a series of mechanical,
permeability, and chemical compatibility tests we will demonstrate
the materials' ability to withstand the high temperatures,
pressures and buffeting winds found in Venus' lower atmosphere. The
Phase I program will result in the successful fabrication of two
potential balloon materials, and the demonstration of the
materials' ability to survive the conditions found on Venus. The
more promising material will be selected for prototype development
in Phase II. The successful completion of the Phase II program will
provide NASA with a novel research balloon capable of exploring the
upper and lower atmospheres of Venus in a single mission.
The successful development of our proposed high temperature
research balloon material will provide NASA with the means to
thoroughly explore the upper and lower atmospheres of Venus.
Commercial applications of these materials may include earth
atmospheric research balloons and lightweight compact emergency
parachutes. Processing technology developed will also help in the
fabrication of liners for compressed natural gas, liquid natural
gas, and spacecraft propellant and gas storage tanks.
