Federal Aviation Administration 

Results of FAA Nitrous Oxide BLEVE 

Characterization Testing 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

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 (N2O) 

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/.
