Form 9.B Project Summary

Proposal Number: 08.05-3550

Project Title: Propellant Leak Detection System(709CR2067)

Technical Abstract (Limit 200 words)

Current liquid leak detection methods rely on electrically coupled analyzers which in fact analyze for vapor already present in the environment. A passive, non-invasive technique which detects leaks AT THE SOURCE would speed up the leak detection process, decrease the total leakage, and decrease the hazards associated with ignition sources in proximity to the propellant and worker exposure. Mainstream proposes the use of fluorescent leak detection, the compounds being specifically designed to the fuel so as not to degrade the performance of the system. This is possible since many compounds we have identified for use in these systems are actually performance improvers, and the concentrations needed to produce a fluorescent signature are only fractions of a percent. The detector light and compounds are patent-pending technologies of Mainstream for related applications, and the transference of the innovative systems to advanced propellant systems is the next natural progression. Phase I will optimize and match these compounds for specific advanced propellant systems, and Phase II will package the entire system into prototype, field-use design for prove-out testing by NASA.

Potential Commercial Applications (Limit 200 words)

The development of a passive, non-invasive leak detection technology has applications in the commercial and government space launch industry, in addition to commercial and military aircraft. This technology will increase safety during missile launch, servicing, and handling of volatile fuels. A detector such as this could also be used as part of a fuel "tag" program, and in assisting the development of new, advanced commercial jet fuels.
