Egg Flight:
The Rules
1) Each student designs, builds, and flies their own airplane.
2) It must be heavier than air – no helium, NO hydrogen.
3) It must fly on its own. It cannot be thrown the distance.
It must fly the distance.
a. No catapults, etc.
b. Must produce its own lift
4) Egg must be treated as a human pilot.
a. No cooking, dipping in protective material, duct-taping, etc.
b. This prevents the concept of cutting out the center of a Frisbee and
securing the egg in the middle (think about it)
c. The egg must land with the airplane
5) No flames (including internal).
6) No liquids
7) If a propeller is used, it must pass the no blood, no bruise test.
8) Must be transported easily from home to school and pass easily through
doorways
9) Any test flights that are not conducted from the ground must be
supervised or approved by your parents.
10) You may get help from any available source.
a. Pay close attention to the posted after school help sessions!
b. Your aunt who is an engineer for Lockheed Martin is fair game.
Give her a call.
11) Recommendation: do not use balsa wood for hang glider frames
Closure
1) On flight day, students are given a flight window when they can do 10
flights from Kill Devil Hill ( the hill above the track, behind the school)
2) A data table must be kept for all of their flights.
3) Broken pilots may be replaced, but that must be recorded.
4) Flight grade:
100 % (3) is given to all students who have a minimum of three flights with an
average greater than or equal to 2:1 and the egg survives.
An additional 10% is given for each whole number increase in the glide ratio
a. 3:1 = 110% (3 1/3)
b. 4:1 = 120% (3 2/3)
c. 5:1 = 130% (4)
10 % deduction if the top three flights averaging between 1:1 and 2:1
20 % deduction if the top three flights average less than 1:1
10 % deduction if the egg breaks on ANY of the flights
