Unsolicited Proposal To Modify Shuttle External Fuel Tank

Abstract, Introduction Project Description
This unsolicited proposal asks as a research paper if construction changes
in the Space Shuttle External Fuel tank could resolve chronic foam problems
1. Foam insulation for external fuel tank to be created using single
common injection mold with a light weight metal matrix for support designed
to be pulled in place over the fuel tank.
2. A second variation would involve cutting the prefabricated foam
unit in half vertically and installing it by snapping it shut over the fuel tank
and locking it later.
3. A light metal matrix outside the complete foam unit it used to
support the outer skin of silicone seal which like the material used
commonly on roofs is sprayed on.
4. The proposed change created an inner foam protection surrounded
by a lightweight; waterproof; and resistant to ice silicone layer of silicone
seal which is extremely adhesive and I have found over 30 years
actually very difficult to remove once it dries.
5. If NASA or Lockheed Martin are interested in this concept I would
suggest a small model of the tank be constructed and tested in the windtunnel to approximate shuttle launch conditions.
6. The ultimate purpose of this research proposal is to add structural
support to the foam and create a highly durable silicone seal around the entire
structure to prevent materials flying off the external fuel tank
Management Approach Personnel, Costs, and Facilities
If the research idea herein was in favor the management NASA and Lockheed Martin would have to secure outside contractors to create the special molds;
metal support skeletons; and silicone spraying crews all of which are
commonly available throughout the United States. If your organizations
require me to act as consultant I would require transportation to your
offices on Greyhound; motel accomdations; food...
8. Other Matters
If NASA is willing there are some other modifications of possible modifications of Space Shuttle tile systems which might expand the life and use of the shuttle systems which could be introducted later. I have an extensive online resume which parties interested in knowing more about my backgound can consult
