Internal combustion chamber porting

Post by Jutte » Sun Jul 26, 2009 7:10 am

Just looking through the Boeing patent for a bank of 'Pulse ejector thrust augumentor' bank -
you know the one proposed as a lifting unit.
The bit I found interesting is the proposed use of internal ports in the combustion chamber - apparently externally fed-
to create a 'boundary layer plenum' - have a look at US patent 6926231.
Any ideas of the 'why' behind this ?
Control of heat,introduction of starting air, the control and mixing of the fuel/air plug is a few of the things I thought of.
The whole patent covers just more that the Pulse jets - looks like they are also angling to have a air droppable
troop carrier deployed from a larger craft.Halo deployed gunships perhaps?
Any ideas?

Well some of what they say seems to indicate acoustic breathing control, but it seems more likely they took a page from Mesherschmidt In the thermodynamic area ( read as flame holder ) but have NO desire to sight the prior art....

You should take all of this as some what wild speculation. I am often wrong.

In the process of moving, from the glorified phone booth we had to the house we have.

No real time to work on jets, more space, no time.

Life still complicated.
