Here
is a sort of repository for aerospace
school stuff.
Here
is a FORTRAN program that helps you cheat at Boggle (5x5
version). The zip file includes a blank word list, an instructional
txt file, and the FORTRAN source. Words can be
added with "Words.exe." One time this program found over 50 unique
four letter words in one 5x5 Boggle matrix. See if you
can beat that. Download boggle.zip
and decompress it with WinZip
or a similar utility.
If
you are mathematically inclined, the problem below might be
of interest to you. Anyone who independently solves at
least one part of it is eligible to receive an official Weed
Wacker Aviation Certificate of Genius email. The rules
are: no numerical solutions, and the solution process must
be shown. Try to solve the problem without referring
to published material. Submit solutions to
bjshowman@weedplane.com.
The
following problem is one that might be encountered when
studying the trajectories of guided missiles or airplanes
homing in on a specific point in space.
An
aircraft is homing in on a radio beacon with a cross
wind. The wind direction and speed are arbitrary and
fixed. The wind velocity is taken to be relative to
the radio beacon reference frame. The initial position
of the airplane can be anywhere except directly upwind or
directly downwind of the beacon. Assume that the airplane
flies at a constant true airspeed with the nose always
pointed toward the radio beacon. Find:
-
A
generalized geometric equation for the path of the
aircraft as it homes in on the beacon.
-
A
set of equations that describe the aircraft's position
at an arbitrary time.
