safety research technical group,GSRTG）Civil aircraft accident system was risen to 1966 to 2009 whole world 3726
Meter is the results show that share 370 accidents related with fuel tank combustion explosion.It can be seen that, it is necessary to it is prevented using effective measures
Aircraft fuel tank fires.
Aircraft fuel tank upper space is full of flammable gas mixture, and inflammable, explosive feature seriously threatens aircraft
Safety, it is necessary to adopt an effective measure to reduce the probability of its combustion, outburst life, and reduce its extent of injury.System is protected in fuel tank
In, fuel tank explosion on fire can be prevented by reducing fuel tank upper gaseous phase space oxygen concentration, ensure passenger and aircraft safety.Reduce fuel oil
Case oxygen concentration can be used the gases such as inert gas such as nitrogen and carbon dioxide and carry out fuel tank inerting, and so that its oxygen content is reduced to can
Fire the limit or less.Currently, hollow-fibre membrane produces the airborne nitrogen inerting technology processed of nitrogen-rich gas（On-Board Inert Gas
Generator System, OBIGGS）It is that most economical, practical fuel tanker fires suppression technology.But OBIGGS technologies
There are still many problems, such as detach that membrane efficiency is low to lead to that aircraft panelty is big, seperation film entrance demand pressure height causes very
It can not be used on multi-model（Such as helicopter）, tiny film wire and infiltration aperture gradually block and air source in ozone lead to film properties
Cause fuel-steam to leak when decaying is serious, nitrogen-rich gas fills fuel tank and pollutes environment etc..
