The Idea
Three years ago, a group of seniors found a video from the
annual Birdman Competition held in Japan. In this competition,
private companies and organizations construct large gliders
and human powered aircraft, and see who can get them to
travel the farthest when pushed off a cliff overlooking
a harbor. Seeing this video inspired the seniors to construct
their own human powered airplane.
Research
They began by purchasing a radio-controlled airplane and
using the wing as a model to build their own scale wing.
Unfortunately, this wing had many problems, so rather then
working down a dead end; they began to talk to some people
from the Birdman Competition. The people they contacted
told them about a man named Dr. Paul MacCready, the first
person to ever successfully fly a human powered aircraft
in a "Figure 8," winning him the Kremer Prize from the British
Crown. After purchasing copies of Dr. Paul MacCready's biography
of the project and a video documenting his first plane,
the Gossamer Condor, the seniors finally had an opportunity
to meet Dr. MacCready and talk to him about building an
HPA. Dr. MacCready gave the seniors a copy of the blueprints
of the Condor, along with a lot of advice, and the stern
warning that HPAs aren't a good project for high school
students.
Work Begins
Using what knowledge they could, the seniors began work
on the airplane. They did a tremendous amount of fundraising
and PR work, getting several thousand dollars, which went
towards purchasing materials. By the end of the school year,
the HPA team had grown to include a group of sophomores
in addition to the existing seniors. This team had completed
the design of the airplane, working from the Condor blueprints
and then modifying them until they had their own, unique,
airplane. They worked tirelessly through the summer, until
early August, when they decided to make an attempt to fly
the still-incomplete airplane.
San Bernardino Airport
In August, the hottest month of the year, we moved almost
the entire Engineering Tech lab out to an open hangar at
the San Bernardino Airport, where we would attempt to complete
the plane and fly it. After working for seven days, we had
completed all of the wing sections and had them attached
to the fuselage. For the first time, the airplane started
looking like just that. Unfortunately, we discovered that
our tail section was far too heavy and that it would never
fly in its present state. Rather than just pack up and leave,
we decided to try to pull test the airplane. This involves
attaching a rope to a bicycle and pulling the plane at a
low speed to try and achieve lift. When we decided to try
the test, it was about six in the afternoon, and we were
all exhausted from working, but had renewed energy, thinking
we would see our creation get off the ground. Without discussing
the flight plan, we hastily started the test, pushing it
at about 10 miles per hour, much faster than we should have.
The plane definitely got lift- too much, in fact. With so
much lift, the left wing went into a stall, and the strain
on the wing caused one of the tubes to fail and bend. Hearts
broken, we tried to make a new wing section the next day,
but it just wasn't meant to be because that afternoon, a
sand storm rolled in and destroyed most of our wing sections.
Rebuilding
The following year was spent reorganizing the plane and
redesigning a lot of the problematic components. Being that
the remaining team members (the rest went off to college)
were all juniors, and previously the scrubs, there was a
lack of organization and leadership. We were able to talk
to a lot of people who have worked with airplanes, including
Paul Illian, a Boeing engineer working on a state of the
art HPA that he hopes will be the first to fly 100 miles
nonstop. By the end of the year, we had successfully redesigned
and rebuilt much of the plane. Currently, the plane is nearly
complete, for the second time. We are planning on taking
it out to March Air Force Base in Riverside over spring
break for another attempt at flying it.
