The Plan
The team has identified some of the complications they envision from the
parameters of the project: All crafts must be powered by the same electric
motor, carry the identical payload, take-off in less than 300 ft. on grass,
and carry a radio control system with up to seven channels. Remember, each
team has the same set of requirements. Pearl team members plan to stabilize
their craft using reflexed camber line airfoils, a wing sweep and twist,
and additional winglets or flaps. They also believe the proper payload arrangement
will increase the stability of their vehicle, which is why they are opting
to use the wings for storage. The GPS, circuit board, electronics box, and
battery will all be placed inside the airfoils. The team is not using a
fuselage or a tail. Instead, the Pearl will feature two main spars for structural
support, a thin balsa wood skin, and a 4" x 14" cutout in back
of the wing for the propeller. A high-friction skid will be centered underneath
the wing
in lieu of landing gear or wheels.

| Team 1 believes following their
plan will allow the Pearl to take off in approximately 211 ft., substantially
less than the 300 ft. allowed in the mission requirements. With a final
take off weight projected at 6.26 lbs., the Pearl is heavier than the
other vehicles they studied in preparation for their initial design and
presentation. Can they do it? |
