A Smoke Detection System for Manned Spacecraft Applications.

摘要

This report describes the development, from concept to hardware, of an open path optical system for detecting smoke in manned spacecraft. Studies were conducted on the nature of light scattering through smoke as well as the nature of the particle statistics in smoke. These studies resulted in the selection of the 2537A wavelength for smoke detection and the use of the 2537A/3129A ratio for discrimination from background particulates. Test results on the first laboratory unit constructed are included, and indicate that the concept is feasible and practicable. Present programs in this area are discussed in the Summary and Conclusions section of this report. (Author)
