2019 Payload Pick-Up Challenge

This Year’s Game
In the Payload Pick-Up Challenge, student teams will design, build and fly an airplane that will pick up payload (in increments of 50g) prior to takeoff.
Team Rules
·        Each team may consist of up to 3 students.
·        Teams will compete in one of two divisions: Middle School (grades 6-9) or High School (grades 9-12).  Ninth grade students in schools that serve grades 9-12 will compete in the high school division. Otherwise, 9th graders will compete in the middle school division
·        There is no limit to the number of teams per school, but each team is limited to one airplane.
Event Parameters
·        Teams must bring one electric aircraft, the team’s visual display, and any tools necessary to repair or modify the airplane.
·        Supervisors will provide the flight circle (Starfish Education- LEAF Flight Circle Kit), specified payload (Eisco PH0258NSS/ PH0258MSS or PHZNW500SET) and other necessary items needed (safety cones, extension cords, etc.) to set up a flight circle.
·        The central tower will be wired using 20awg speaker wire. The line from the tower to the airplane measures 1.83m (6 feet) from cap to the tip of the alligator clips and the line from the cap to the power supply measures 3m (10 feet).  This dimension includes the height of the tower which is approximately 1m (38 inches).
·        Students must wear eye protection at all times when in the cordoned-off area. 
Airplane Design
·        Teams must use an electric motor (Kelvin #850647, #851950 or TeacherGeek #1821-70) and are limited to one motor per airplane. The motor must be installed in the airplane so as to be clearly visible to the judges on the day of the fly-off.
·        Teams may not modify the required motor (including, but not limited to, use of a gear drive).
·        Airplanes may have one wing with a wingspan of no more than 51cm (approximately 20 in).
·        Teams may construct a housing to hold the payload prior to pick-up.  Payload housing must be passive and no larger than 5cm (2 inches) in any direction.
·        No commercial kits or lighter-than-air materials may be used.
·        Teams may use any type of wheeled take-off and landing gear.
·        Teams may use any type of non-metallic propeller and/or hub and no metal may protrude from the front of the airplane.
·        Magnets may not be used.
·        Electricity to the motor will be supplied by a variable power source and central tower.
·        Leads will run from the motor to the tip of one of the plane’s wings to allow alligator clips and a safety hook to be attached quickly and easily.
·        Each team must clearly label their airplane with their team name and assigned number.
Flight Circle Parameters
·        The flight circle will be constructed with a central tower at the center of the circle with 1.83m leads (6 feet), creating a 3.66m (12 foot) flight circle diameter. Alligator clips and a safety hook will attach to the ends of the leads to allow teams to easily attach and detach each team’s airplane. 
·        Safety cones or stanchions will be placed around the perimeter of the flight circle.
Fly-Off Rules
·        Teams may make as many attempts as time allows, but no one attempt may exceed 2 minutes. 
·        Students will first demonstrate proof of concept by flying two or more consecutive laps without touching the ground.  All airplanes must start at the designated location, a pre-designated radius line marked by tape and labeled Start.
·        After a successful flight, the timer will be paused while students place the specified payload in the flight circle along a pre-designated radius line (marked by tape and labeled Payload).
·        Once payload is placed, the timer will resume.  Students may use the remaining time to attempt to pick up the specified payload.  Once it has been successfully picked up, the airplane must fly two successful laps carrying the payload. Upon a successful payload pick-up and flight, the timer will again be paused to add more weight to the specified payload and place it in the flight circle. Payload weight will increase in 50g increments. This procedure will continue until time runs out.
How to Win
Scores will be comprised of two parts for a total of 100 possible points:
Visual Display Score (40 points)
         Teams will submit their visual displays at team check-in on a 20” x 30” foam board. Visual displays on larger size boards will be disqualified.
         Information may only be displayed on the front of the board and may not hang over the edges.  Information hanging over the edges or on the back of the board will not be scored.
         Two judges will evaluate visual displays for completeness and quality using the provided score sheet.  Suggested components are: Team Number, Team Members, School/Organization, Design & Development, Scientific Principles, Testing Data, Problems Encountered, Conclusion, Material Resources, Working Drawings
         See the Visual Display Scoring Sheet for more details.
Airplane Performance Score (60 points)
   Teams will earn 10 points for flying their airplane as a proof of concept.
   Teams will earn an additional 5 points for each additional 50g of payload their airplane can pick up prior to take-off.
         Ties between teams will be broken by the highest-scoring Airplane Performance.
Notes to COAches
The majority of the work on all phases of the project is to be done by students.
·        Limit adult assistance to mentoring students, teaching principles applicable to the project, assisting in production of the report and drawings, overseeing manufacture of the project, performing any process that may pose a safety hazard to students, etc.
·        During the design and testing phase, guidance should be in the form of questions to promote creative thinking by the students.
