Results of FAA Nitrous Oxide BLEVE Characterization Testing

Action

Notice Of Public Teleconference.

Summary

This notice announces a public teleconference to share with the public results of recent FAA sponsored testing of nitrous oxide (N 2 O) characteristics. Nitrous oxide is an important oxidizer to developers of some commercial reusable launch vehicles. A potential hazard in nitrous oxide storage and handling is a Boiling Liquid Expanding Vapor Explosion (BLEVE), which results from a sudden loss of pressure in a tank containing nitrous oxide stored under pressure above its normal boiling point. The FAA's Office of Commercial Space Transportation sponsored tests of liquid-phase nitrous oxide at NASA's White Sands Test Facility to empirically determine the superheat limit temperature for nitrous oxide, and to demonstrate that a BLEVE would not occur if the liquid is maintained at temperatures below this superheat limit temperature.

Meeting Information: The teleconference is scheduled for Thursday, February 28, 2013, from 1:00-2:30 p.m. Eastern Standard Time. The presentation and call-in number will be posted one week in advance at http://www.ast.faa.gov/.
