This week @ULSF we’ll meet the original, broad definition of “ULSF” as looking out at the world more than looking into our own group.  Following from @ULSF we see @Odyssey_Moon wishing everyone in the US a Happy Fourth.  @ClydeSpace sees young James Tiberius coming up through the classic apprenticeship.  And @AstroTek shares @MilesOBrien always loves a good lander flight test.  @NASA_Wallops wishes us a safe Independence Day with a historical note that on this day in 1945 they launched the first Tiamat research rocket.  As always, @AronSora is tweeting a universe of space ideas.

Alex @Csete has been pointing Gnu Radio + the USRP at NOAA satellites this week, great articles at OZ9AEC.

Lockheed XFV-1

For my own part, I’m still working on this
and learning OpenGL — instruments of study and work.  I’m happy to be gaining traction with OpenGL and making some (albeit minor) progress on the space
plane design study project
that all of this effort is primarily
pointed at.  This week I opened “elme”, electro-mechanical simulation
software project with “Prop”.  This is (the beginning of)
a variable pitch propeller using a helicopter style control plane for
vectored thrust.  A pair of these counter rotating will be used for atmospheric flight control, but reminds me of a very similar configuration used for thrust in the
Lockheed XFV-1 project.  My grandfather worked on the propeller pitch control gear set for this project.  Makes me  warm and fuzzy to find a variable pitch propeller in the position of a favored solution.
