A new update from Robert as he continues his work on his liquid-fueled rocket, working towards an all up static test soon.
The test stand blast deflector for vertical testing is complete. It uses three 24 x 24 x 2 inch concrete pavers at 30 degree increments to deflect the exhaust horizontally down the flame trench in my test pit. The frame is made of 1.5 x 3/16 inch steel angle. A negative step of about 0.1 inches between pavers will hopefully minimize erosion on the leading edge of the downstream ones.
Roberts also goes into detail about some of the flight avionics and some engine maintenance.
His updates and work are very professional with loads of information, check out his site here.
