Rocket science isn’t rocket science

Tandon students at Rogue Aerospace showcase the start to finish of a rocket launch.

Rockets don’t have to just be the toys that Elon Musk got bored of before he bought Twitter. Rogue Aerospace members, a team of rocket enthusiasts, launch rockets to bring their classroom learnings to life while earning certifications from the National Association of Rocketry.

Rogue Aerospace is one of Tandon School of Engineering’s Vertically Integrated Projects, research and innovation programs that apply multidisciplinary engineering skills to build or design products from self-driving technology to off-road race cars and rockets.

The Tandon MakerGarage, a workshop dedicated to VIP students, is the home of Rogue Aerospace. Miller and Xu design and build their rockets there before launch.

Rogue Aerospace has won awards and recognition from NASA and Northrop Grumman, a US defense contractor researching aerospace and aeronautics technology.

To receive NAR certifications, designers must successfully launch and recover their rockets. Designers package a timed parachute deployment system into the rocket’s body to slow the rocket’s descent. The motor generates lift during the launch and powers the ascent. The fins stabilize the rocket during ascent. Once the motor has exhausted all chemical fuel, the rocket coasts and continues to gain altitude until it hits apogee – the maximum altitude in its trajectory.

As soon as the rocket reaches apogee, a small and secondary parachute, known as the drogue, deploys before the main parachute so as to stabilize the descent and prevent the main parachute from tangling. On-board sensors and timers release the main parachute at an altitude predetermined by the designers. The rocket then lands and is ready for recovery.

On-board electronics such as altimeters and barometers help document flight data and determine parachute deployment.

Miller’s rocket reached an apogee of 3766 feet, approximately equivalent to three Empire State Buildings stacked on top of each other.

Data collected from Miller’s on-board electronics indicated that the rocket reached a maximum speed of Mach 0.8, approximately 627 mph or 1010 km/h. For reference, the top speed of a Boeing 747-400 is around Mach 0.85, about 652 mph or 1050 km/h.

Alex Miller and Alex Xu showcase their level two certifications after their successful launch.

“Although it took us a while to successfully launch both rockets, we both passed our level 2 [NAR certification],” Xu said. “I’m looking forward to launching more high-powered rockets and trying to move to level 3 in the future semesters.”
