This plane was designed last year in the first term, for flying in Maths 1A
lectures in the Cockroft Lecture Theatre, New Museums Site.
It can be thrown very hard and has a nice flat trajectory, but is by no
means an out-and-out dart. It also has the benefit that it is very easy to
fly - you can just pick it up off the floor and chuck it.
Notes on contruction
In terms of constrution it is slightly more awkward than Plane No. 1 to build.
It has a different beginning, but the same ending folds as Plane No. 1.
Use a piece of A4 paper (297mm*210mm) to make this plane. Crease the
horzontal fold, then the standard start with the diagonal folds, but
only crease these.
Fold so the edge of the paper and the previous folds meet. Make sure that
the folds go right to the middle of the left hand edge of the piece of
paper.
The vertical crease should be made last, as it must intersect the two
diagonal creases and the horizontal crease.
Same as for Plane No. 1. If the previous creases are strong then this
should be obvious. The two flaps that go 'inside' will have to lie on
top of each other as they both cross over the horizonal fold line. It
doesn't matter which lies on top.
This is a tricky fold. The 'inside flaps' are folded inside the large
triangle on the left of the paper. For each side in turn, it is
easier to unfold the other side to give you room to make the fold.
As a guideline, make the fuselage about 2cm deep, and the vertical flaps
about 3cm. Again, these folds need to be parallel otherwise the lift
of the plane will be affected.
Notes on throwing
Fold the aeroplane so that the angles between the fuselage and wings, and the
wings and the flaps are both 90 degrees. Hold just behind the slight bulge
in the fuselage (about 9cm from the front of the plane), aim at your lecturer
(preferable the back of his head) and throw hard. This plane excels in
lecture theatres for over 300 people.
