The Lab Liquid Sounds & # 39; University prepares for showdown of & # 39; March

From 1942, when Wernher von Braun launched a liquid propellant rocket & # 39; 2 tons (and deadly V2 missiles) in space, there were more than 5,000 rocket hike, many of NASA, some Chinese space agencies and Russian and, from SpaceX and other firms & # 39; commercial space.

But Liquid Sound Laboratory in & # 39; Ci Poly Pomona must be the first team based at the university to remove & # 39; over 45,000 feet and, in the future, in space.

CPP Liquid Rocket Lab PCMag was invited to meet & # 39; to & # 39; rocket team, Bronco, the team of its aerospace engineer and supervisor Dr. Frank Chandler, Assistant Professor in the College of Engineering to teach the Design & # 39; Aerospace, Propulsion and Dynamics of computational fluids .

"I take – [1950s] October Sky generation ", Professor Chandler told PCMag when we arrived." Inspired by the first Sputnik rocket to enter. I spent & # 39; 40 years in the aerospace industry, first at & # 39; Powerwell International, then Boeing, as were sharpening on the Apollo program. During that time I worked on several NASA programs, including the Space Shuttle, we support the mission, while an analysis sekwistra rocket launch, and make sure that will bring back astronaut increased. "

In Conference Room & # 39; the Engineering & # 39; Aerospace, we found on information from Dr. Chandler to team subset of & # 39; 70 members: Richard Picard, Alfredo Herrera, Tatsuya Danno, Colby Truong, Eric Gonzalez and Jesus David Montes all students studying Aerospace, engineering, math, or physics.

Then we all going at Building 13, which is the Structures Lab. It's a great building & # 39; hangar kind Stuffed rokitetiku equipment: tools, sensors, tubes, valves for transporting cryogenic fuel rocket, the nose cones, parachutes, the tail tail and raw materials ranging from wood to fiber -karbonju of & # 39; tech in & # 39; several workbenches.

Bronco 1 is f & # 39; present pieces as the team working on it. But in the full range, is & # 39; 15 feet tall, weighs 115 pound, has liquid methane fuel engine, aluminum / fiberglass "skin," swan ablative cooled Engine, and is funded by a gift & # 39; $ 1.67 million from.

Here are some of the players talking about their special responsibility on Bronco 1:

1 Bronco was through & # 39; various tests over the past year, including one earlier this year on the site & # 39; Launch Dry Lake Lucerne in & # 39; half the Mojave Desert, in & # 39; altitude & # 39; 2,848 feet.

"That night, the test team into & # 39; here quite late in the laboratory, making tests & # 39; before launch," said Alfredo Herrera. "Then we go about 4 a.m. in & # 39; Samra have made loans from College of Engineering. For purposes & # 39; safety, the rocket has been broken and we have assembled on site."

"The most vulnerable components going into & # 39; protective Pelican cases", added Richard Picard. "Others we wedge between ice chests in the back of the truck."

When they arrived in the desert & # 39; Mojave several hours later, the team dropped their fleet & # 39; vehicles came in & # 39; formation, each committee with a list of & # 39; own tasks. They worked for more than two hours until they were ready to launch uploading to departure.

"[We] went to the Rangemaster, said pad to which we will nidiedu it, put it on, set the altimeters and ran in & # 39; safe distance, "said Picard.

Satisfied that all safety checks have been made, the Rangemaster started the countdown and Bronco was one remove. Here video clip the day to win the team member Eric Gonzalez on his phone. If you are at work, turn your speakers bright.

"Then we all asked the parachute opened," said Tatsuya Danno. "You start to see it on the tip and then" pop & # 39; -It amazing feeling. "The parachute has a transmitter mounted GPS, so the team can & # 39; locate the rocket and bring it back to the lab.

Bronco 1 is constantly undergoing testing. "Our first will be the first" test & # 39; engine & # 39; hot fire ", explained David Jesus Montes. Each part of the rocket requires testing, and is easier and more effective to make each b & # 39; an isolated way."

"We need to ensure that our electronics can & # 39; handling cryogenic temperatures," said Gonzalez, "and the plumbing and all parties work with & # 39; correct way. The next test environment will be on campus, and take at least two dozen components, including solenoids, valves and run through which liquid nitrogen, to 286 missing [F] to ensure that nothing starts under those conditions. "

if you follow CPPLRL on Twitter, they will send updates from that test day and & # 39; debrief allowed.

After all, everything is aimed at one goal: the competition & # 39; & # 39 Launch; FAR Mars on 2 and 3 & # 39; March 2019. Backed by & # 39; jointly by the Mars Society (Denver) and Friends of rocketry enthusiasts (California) the desert Mojave, but nobody won the prize & # 39; $ 100,000.

"This is why the launch of & # 39; liquid rocket powered & # 39; over 45,000 feet is a serious and complex task," explained Professor Chandler. "But if any team can & # 39; to do so, in 2019, it is. This is a large group & # 39; engineers. I think it should all go to gradual school and I know that have great careers before them in aerospace . "
