NOFBX use in Dragon?
« on: 03/06/2011 07:32 pm »
So, Max Vozoff is now pushing this via his involvement in ISP Systems, as noted during his Space Show appearance -

http://www.ispsllc.com/nofbx.html (very new site - in development)

 AIAA PDF....

Wonder if it has enough potential thrust to be used in Dragon Crew's landing thrusters, making it possible to lose the hypergolics in Dragon generally? 

Opinions?

A monopropellant with an Isp of 320-340s? Sounds like there might be military applications as an explosive with much higher energy density than TNT... :-)

Anything premixed with that kind of energy density will detonate if pushed hard enough. And we have seen from the scaled composites accident that even nitrous can detonate.

Well, another thing he mentioned is that the tech will go to ISS (pg 14) for testing in 2012 thus generating a flight history.

Have no idea if it can do the job, but I imagine if it can SpaceX would give it a look. Anything to make Dragon ops and turnaround smoother.

*If* this works, it would certainly solve some of the difficulties of liquid LAS and landing systems.

Certainly sounds too good to be true though...

If a thruster using the propellant has been fired someone could have filmed it.  Publishing that on YouTube will make a simple marketing tool.

A single large thruster able to form part of a LAS can be tested by itself.  That will permit any problems to be discovered and get it up to a suitably high TRL level.

Eh?  The video is on their website.  Here is an image from Mungas'  paper which was linked above.

It does sound too good to be true.  Monopropellant, Isp>300 sec, non-toxic, stable, low mass and complexity engines....

If this works as stated, it could be important to many systems beyond Dragon.  The paper says that they are "Working with 4 CCDev vehicle teams" already.
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

There's already a thread about NOFBX:
