I've
always thought that rocket gliders were the biggest challenges. There are
really very few. Most of the favorites (Crusader Swing-Wing, Scissor Wing
Transport, Citation Bomarc, Trans-Wing, Deltie, Soaring Eagle, Mach-10,
Mini-Dactyl, SST Shuttle, Swift, Nighthawk, etc,) are boost gliders
which use a pop-pod which is ejected. The most simple of these favorites
like the X-24 Bug, etc still eject the engine casing. The only true
Rocket Gliders I can think of are the Estes Tomcat, Edmonds ECEE, and
some competition models. Competition models generally use nose mounted
engines with burn string activation for either sliding wings and/or
control surface activation. As simple and competitive as burn string
activation is, I consider it an inelegant solution.
The Falcon eXtending Tail Rocket Glider uses the ejection charge to extend move
the CG backwards and also activate the aileron. A moving control surface
on the tail isn't really necessary, but I'm concerned about getting a straight
boost.
My original design criteria:
1) True Rocket Glider.
2) 15 degrees minimum wing dihedral.
3) Scalable to 13 mm engines for A / 1/2A RC competition.
4) Constructed from readily available parts
5) Quick prep - No burn string. "Plug and Play"
I have some initial sketches for a Generation II XTRG which will be called the "Raptor."
