Ventus 2cxa with FES

I have a question about the history of soaring... (I'm not asking a practical serious question.)

Has anyone tried and/or had any luck with a 'slow burn single use' solid rocket in a glider? It would have the advantage of high energy density, low drag and quick start. I suppose that it might melt something important if it were were mounted on the fuselage. What about a wing mount close to the root?

I know this idea sounds crazy, but a pop-up jet sustainer strikes me as only slightly less outrageous.

Germans did Me-163. I know that it had not an 'slow burn'
solid rocket, but it was liquid fuel, but still it was glider
with rocket engine

.....but never something you could call a 'safe ride'.

Cool video, though.

As for whether or not it is practical, ask the high altitude model rocket guys how much the spend on a "shot" for one of their rockets with not near enough propellant to launch a glider. Then go take a couple of tows and see which you would rather do. But it is an interesting thought.

IMHO it doesn't matter what kind of engine you have - at the
moment you reach for the start button of any motorised glider
you have to be 100% certain in your mind that it will not start
and have planned for that possibility. Then its nice when it does
start.

The actual probability of the engine not starting may vary
depending on the type and service status of the engine system
but the short term internal mental tool of 100% certainty of non-
starting should not.

(Even with the FES)

Perhaps the plan could be the same one you have for the wing spar
breaking, or a control rod disconnecting.
