|Experimental 2400 lbs thrust solid fuel rocket motor static test (2011-06-17) |
Successful static test of a 152mm (6 inch) diameter rocket motor. 49907 nsec total impulse (P7371). 2400 lbs. max thrust. 1656 lbs average thrust. Burn time 6.76 sec. Burn rate .24 in/sec. Isp 235. June 17, 2005 Black Rock Desert, Nevada. Normal speed video followed by video slowed to 1/4 speed. Thermite igniter brings motor up to pressure almost instantly. Motor was undamaged by firing, reloaded and flown a few months later.
|Experimental Solid & Hybrid Rocket Motor Static Tests March 20, 2004 (2011-06-17) |
Several 24, 29 and 38mm experimental solid fueled rocket motors are tested on an instrumented test stand and a nitrous oxide hybrid rocket is fired using salami as a fuel grain
|Experimental solid fuel rocket motor 11 second burn time (2011-06-17) |
Successful static test of a 4.5 inch (114mm) diameter solid fueled rocket motor. D-slot grain. 11 second burn time! M700.
|Failure of 2400 lbs thrust rocket motor in flight at Balls 2005 (2011-06-17) |
Flight test of a 6 inch diameter 2400 lbs thrust solid rocket motor. Rocket weight at takeoff = 145 lbs. Motor was designed for a two stage 220 lbs rocket, but rocket was not ready in time and a lighter weight single stage airframe was substituted. As a result, the thrust to weight ratio was 16 to 1 (too high) instead of a more sane 10 to 1. Recovered flight data indicated acceleration exceeded 40 g's. Propellant grains collapsed under the high acceleration causing the chamber pressure to exceed the max design pressure of the motor case. The forward closure failed, ejecting the forward bulkhead and separating the airframe. The rocket tumbled end over end at ~Mach 2, and the resulting aerodynamic loads shredded it into pieces which fall and impact the desert.

|Failure of 4.5 inch solid rocket motor in flight (2011-06-17) |
4.5 inch (114mm) diameter solid rocket motor with a D-slot grain fails in flight. The grain was recovered and the cause of the failure was over pressurization of the motor case due to the D-slot grain not being completely inhibited by the spiral wound phenolic casting tube. The spiral grooves in the casting tube allowed the flame front to burn on the backside of the grain, increasing the burning surface area (and chamber pressure) beyond the design limits of the motor. Rocket was a full scale model of an ARCAS HV. Balls Experimental Rocket Launch Black Rock Desert Nevada Sept. 19, 2005
|Geoff's ARLISS rocket has a successful flight (2011-07-13) |
Geoff's ARLISS rocket has a successful flight on an Aerotech M1419 a deploys a payload for Japanese engineering students. Black Rock Desert, Nevada September 2002
|Hybrid Rocket Flight to 21000 ft. (2011-07-13) |
A 4 inch diameter rocket with a hybrid motor burning nitrous oxide and ABS plastic is successfully flown to 21000 ft. and recovered. Black Rock Desert, Nevada
|Hybrid rocket motor powered ARLISS rocket (2011-07-13) |
A successful flight and recovery of Geoff's ARLISS rocket on a hybrid motor burning Nitrous Oxide and an ABS plastic fuel grain. Main parachute deploys just in time.

|Large V2 rocket crashes at LDRS XX (2011-06-22) |
A large scale model of a V2 rocket has a scale like flight during LDRS XX at Lucerne Dry Lake, CA.
|P rocket motor CATO at BALLS (2011-06-22) |
A 6 inch diameter "P" solid fueled rocket motor has a Catastrophic Failure at Takeoff (CATO) at the BALLS launch Black Rock Desert, Nevada
|Project High Jump at BALLS 2011 (2011-12-08) |
Boosted Dart Project at BALLS 2011 Rocket Launch. Motor casing burn through, dart airframe seperates from tail cone, Recovery harness seperates, Booster comes in ballistic, Interstage lands under parachute. All parts landed down range.
|Supersonic Carbon Fiber Rockets (2011-06-30) |
Two Carbon Fiber rockets are successfully flown and recovered on experimental solid fueled rocket motors. One is 1.5 inches in diameter and the other is 2.25 inches in diameter, both exceed the speed of sound. The 2.25 inch rocket is recovered with melted paint from the "evil speed" Black Rock Desert, Nevada
|The Best Rocket Launch Ever 2006 (2011-06-28) |
A small private launch held at the Black Rock Desert Summer 2006. 6 inch OD ARLISS Rockets successfully flown on experimental 114mm N and 98mm M motors. A 3 inch minimum diameter rocket flown twice in same day to Mach 2 and 24000 ft on 7000 Nsec M motors. Really old motors from manufacturers long gone out of business. Perfect flying weather, great friends, successful flights on experimental rocket motors, dinner and drinks at Bruno's = the best rocket launch ever.
|Two M Motor Failures at LDRS XX (2011-06-22) |
A solid fuel M Motor flies out of control randomly around the launch pad while spectators run and watch. It is immediately followed by a hybrid "M" motor rocket failure. The hybrid motor is a blowdown type which causes a "buzzing" vibration that spoofs the avionics into triggering the ejection charge and deploying the parachute early while under boost. LDRS XX Lucerne Dry Lake, CA
|Unstable "P" motor rocket flight (2011-07-13) |
Large rocket has stability issues. Powered by solid fuel "P" motor
