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
https://www.ast.faa.gov/.
