Past...Present..Future...Plans (updated)

Past:
On March 5th we watched Garvey space have a perfect flight.
We tested a commercial GPS and out stainless printed motor.

The Motor had cat pack issues,
The peroxide has to flow through the cat pack and not around it.
This is done by adding rings that look like piston rings and expand out against the barrel of the cat pack area and block flow that wants to go around the outside. I disassembled the pack tonight and I had 4 anti channeling rings in the pack. The top ring was fine, the second ring was a bit distorted, the 3rd was badly burnt and thinned and the last one came out in tiny bits. I'm going to try stainless C clips as anti channeling baffles and we will see how that goes.


The GPS stopped updating the moment the motor lit.


Present:
I'm going to use some tougher stainless snap rings as anti channeling baffles.

Today I received my 2nd version of a GPS front end board and hopefully will get to try it this weekend. (rakon grm8652 integrated GPS front end )

The Max2769 eval board is due in on Friday if UPS is to be believed.


Future:
This Saturday we will try firing the small stainless printed motor with modified anti channeling baffles in the cat pack.

Some time in April we might get our first test tank under the Tank development process with we are doing jointly with microcosm.

I have high hopes to have a high dynamics GPS to actually fly by the next FAR outing the first Saturday in April.


My current Plan of record:

1)Work on the small 3D printed motors both stainless and aluminum until I have a viable 3rd stage motor.

2)In parallel work on high dynamics GPS and IMU integration using HPR rockets to test,

3)Tank development continues. (my involvement with this is limited until testing is needed)


4)When I have the high dynamic gps/imu working add some small canard control fins to the
HPR test rocket and see if we can control the trajectory.
This may possibly be done with vanes in the exhaust instead of canard fins.


5)Combine steps 1-4 to see if we can fly a small rocket to 100Km.
