I’d like to preface this post with the motivation and
significance behind this weekend’s launch. When this program began in August,
we sought a means to secure initial funding from the university to build
momentum. As I had done for water polo, we completed an application requesting
Co-Sponsorship from the OSU Student Government Association (SGA). A student on
the committee, Andrew Steadley, was thrilled with our goals and ambitions, and
he advocated to provide our team with the maximum amount of funding available at
the time, $1500. It is thanks to him that our program had the initial funding to get off the ground and build larger rockets.
On January 20th, 2017 Andrew suddenly passed away.
His roommates found him in his apartment, cause of death unknown. This was an
enormous shock to every student at OSU as he had touched so many students'
lives. Our rocketry team already had a big rocket in the works, and upon
hearing this news and remembering his support for our program, we decided to
name our upcoming rocket Steadfast
Steadley after him, honoring the faith he had in us.
Andrew’s favorite colors were blue and purple, and every
student in SGA can attest to Andrew’s purple suit that he wore to SGA
meetings and functions. Our team lead who handles our rocket’s paint jobs was
inspired by the night sky and Andrew’s favorite colors for the paint scheme on Steadfast Steadley. He did an amazing
job beginning at the bottom with a setting sun (also where the bright exhaust
trail would exit the rocket’s motor), blending yellow into red and purple to blue
to end with a starry black sky at the top.
Here is a video to a time-lapse of the partial assembly of Steadfast Steadley.
This is time-lapse video of the motor assembly for the flight.
For the launch of Steadfast
Steadley on February 11th, 2017 we flew the 15-pound rocket on
a 54mm Aerotech K700W motor. Three seconds after motor ignition, it achieved a
maximum velocity of 1,180 feet per second, or 805 miles per hour (1.05 times
the speed of sound). It reached apogee at 8515 feet (1.6 miles), smashing our
previous maximum altitude of 852 feet.
This is the footage of the launch as viewed from the launchpad. The force of takeoff did actually blast the GoPro backwards which worked out well as the camera continued to film the rocket's ascent.
We were unable to configure our GPS for this flight, so we
had to rely on ground eyes. One member of our team could track it with
binoculars, but the descending rocket disappeared behind the sloped fields. For
over an hour we searched from vehicles and heading out on foot over the corn
fields to no avail. A mile and a half from the launch site, I happened to spot
an orange parachute with binoculars while standing in the bed of a pickup
truck. Sure enough, we’d found it. No damage to the rocket, and after we
connected to a laptop, we determined the maximum altitude reading from our
altimeter. Having recovered Steadfast
Steadley, the launch was flawless and we were thrilled to have flown our
best rocket to date in memoriam of our friend, Andrew.
Great post Lucas and congratulations on a successful launch.
