Rocket Science… it’s a BLAST!
For over a decade, I have been teaching the physics of model rocketry at Eastern Arizona College. The basic rocketry workshop covers the physics of rocket flight. The advanced class, using engineering concepts, is a "design, build from scratch, and fly" program, building on the concepts presented in the basic class. During one launch, a four stage "egg crate" was launched. We recovered the payload intact - a hen's egg. Several other advanced rockets put the hen's egg in orbit -- at least we didn't find them... The two stage rocket uses a booster stage consisting of a cluster of "D" or “E” rocket motors which launches the payload, a hen’s egg, to above 1,100 feet and as much as 3,500 feet.
Joe, a student from Eastern Arizona College, is preparing
to launch! As an advanced rocketry student he received his
Level 1 certification by the National Association of Rocketry.
His certification rocket was 9 feet tall and went over 2,200
feet high. It was recovered intact by a two stage parachute
recovery system -- ready to fly again... For those students
of rocketry he used an "I" engine -- 64 times more powerful
than the "C" engines used by the beginning rocketry class.
