<strong>WVU</strong> ENGINEERING AND MINERAL RESOURCES Volume 3 Issue 1<br />

Microgravity Team Takes Flight<br />

By Shainna Sticklen<br />

Tristan Wolfe was one <strong>of</strong> our students<br />

who got to experience weightless flight<br />

last summer at NASA in Houston, Texas.<br />

Students (left to right) Thilanka Munasinghe, Brad Palmer, Jason Gross, Tyler-Blair<br />

Sheppard, Kevin McCrea, <strong>and</strong> Curtis Groves conducted an experiment in microgravity<br />

at the Kennedy Space Center.<br />

While some students played on the<br />

beach, members <strong>of</strong> the <strong>WVU</strong><br />

Microgravity Research Team spent<br />

part <strong>of</strong> last summer’s break conducting inflight<br />

experiments in zero gravity. Led by<br />

mechanical <strong>and</strong> aerospace engineering<br />

pr<strong>of</strong>essors Donald Gray <strong>and</strong> John Kuhlman,<br />

one team headed to NASA in Houston,<br />

Texas; the other went to the Kennedy Space<br />

Center in Fort Lauderdale, Florida, to work<br />

with the Zero Gravity Corporation.<br />

The NASA team included Adam Feathers,<br />

Jackie Grimes, Jason Gross, Kerri Phillips,<br />

Tyler-Blair Sheppard, <strong>and</strong> Tristan Wolfe.<br />

The Kennedy Space Center team included<br />

Curtis Groves, Kevin McCrea, Thilanka<br />

Munasinghe, Brad Palmer, Tyler-Blair<br />

Sheppard, <strong>and</strong> Justin Smith.<br />

The students wrote proposals for their<br />

research projects, then designed, built, <strong>and</strong><br />

tested the experiments before taking them<br />

on board. Once in flight, to create<br />

microgravity, the aircrafts engaged in steep<br />

climbs following by dramatic free falls to<br />

create 25-second intervals <strong>of</strong> near-zero<br />

gravity. The process was repeated more<br />

than 30 times, giving the teams time to get<br />

used to the weightless environment <strong>and</strong> to<br />

conduct their experiments.<br />

The NASA team was investigating whether<br />

there would be a circular hydraulic jump in<br />

microgravity, <strong>and</strong> was attempting to predict<br />

where this would occur. “It would be useful<br />

to know where the jump occurs so it can be<br />

avoided on electrical cooling equipment.”<br />

said Phillips. “In fact, there was a jump, <strong>and</strong><br />

we were able to locate it.”<br />

The Kennedy Space Center team<br />

constructed tanks to study pool boiling in<br />

microgravity. “If you are cooling something<br />

in space, you need to create some type <strong>of</strong><br />

force to pull the vapor bubbles to the<br />

surface,” said Groves.<br />

Weightlessness was different than she<br />

expected, said Phillips.<br />

“The first time you actually feel it, you feel a<br />

drop in your stomach,” she said, “but that<br />

only happens the first time. It feels very<br />

different than you expect.”<br />

This was the project’s seventh year, <strong>and</strong>,<br />

according to Kuhlman, many past<br />

participants in this project have gone on to<br />

successful careers in aerospace <strong>and</strong><br />

aeronautics.<br />

“It is very gratifying to see how students<br />

grow from this experience, in terms <strong>of</strong> their<br />

confidence, communications skills, <strong>and</strong><br />

career goals,” he said.<br />

For the students, the experience was the<br />

opportunity <strong>of</strong> a lifetime. “It was impressive<br />

to meet <strong>WVU</strong> graduates who are working<br />

in the space program, sitting at mission<br />

control,” said Wolfe.<br />

The project is funded through the<br />

Mechanical <strong>and</strong> Aerospace <strong>Engineering</strong><br />

Department, the NASA West Virginia Space<br />

Grant Consortium, <strong>and</strong> the dean’s <strong>of</strong>fice.<br />
