Nike Corona: 2-stage Rocket (LDRS 25)

Edited video from an amateur rocket launch outside Amarillo Texas (LDRS 25) in June of 2006. The rocket featured is two stages, 17ft. tall, and weighs ~130lbs at takeoff. It has flown twice successfully to ~15.5 K ft and is now retired. The rocket motors are solid composite and manufactured by Cesaroni Technologies Incorporated (CTI). The rocket has dual redundancy electronics for all flight events (stage separation, stage ignition, drogue chute deployment and main chute deployment). The altitude, velocity, and acceleration values you see in the video were all recorded by an on board data logging flight computer. Enjoy, the rocket took about two years to design and build from scratch.

Very Cool! That's one of the best rocket videos I've ever seen. I was at LDRS 25 and I do remember your flight. Looking forward to seeing more videos. Keep up the good work.

@TheBayourat Thanks for the nice remarks! I'm glad you enjoyed the launch. Hopefully, I'll get back to building some new designs soon.

it looks something like a nike-ajax anti-aircraft interceptor missile back in the 1950s

@AHGlasher [Where did my first reply go?] You're right, he was indeed. The onboard electronics log all of this - typically redundant integrating accelerometer and barometric pressure sensor devices controlling the recovery system functions (separation at apogee and main chute deployment at low altitude), & upper stage ignition controlled by a preset timer triggered by the G forces from the first stage boost. These devices are available from various vendors serving the high power rocket market.

@AHGlasher [LATE REPLY] So he was, you're right. That's covered in the video description. All large rockets like this carry avionics, pyrotechnic delays like on smaller rockets is generally not used above "K" class motors. The avionics typically contain an integrating accelerometer and barometric pressure sensor to control recovery system functions and upper stage ignition typically by a preset timer triggered by liftoff acceleration. This was one of my favourite flights of the event.

sweet rocket nice job on the two stage...

[AHGlasher]

@gertnood I believe kevinlyman1 was asking how, not what, as in the equipment and/or calculations used to determine the 641.2 mph speed, 15,385' altitude and 6.722 G's attained.

I would like to know as well. 8c)

@jonalululy Almost. Just 126.8 mph shy... :)

[PeanutButterGtr]

Thumbs up if you counted down with mission control...!!!

[PeanutButterGtr]

Omg that was an AWESOME flight!!! Please post a 3 stager video soon!!!

[ctoney1992]

AWSOME!!!

Great work, one of the best Rockets i've ever seen. Keep it up!
