Mr. Jolly,
Thank you for the information you have shared with us.
I know of some nicely deserted mountain ranges down in South America
that will make great testing locations. Will need an inexpensive
virtual cockpit with real-time on-board video and instrumentation down-link.
Is there an online location where I may learn a bit more about this
project you are working on?
And, I would like to kindly ask another question if I may: would
there be any advantage(s) on using a RAM-Jet instead of a regular
turbine or rocket power for the purely fun purpose of reaching very high
speeds at a lower cost? I tend to think that the RAM-Jet would use
less fuel and allow better use of space and weight savings than a
turbine, therefore providing longer lasting flights at higher speeds.
I understand that even higher speeds may be achieved with rocket power
but I wonder about length of flight, range and "throttle" control (if
we are speaking of solid rocket power, I do not know about liquid or
gaseous rocket fuel).
Your input will be greatly appreciated (and anybody else who may want to
add something in this subject).
Thank you again.
Ron Piskulich

Ron,
You can achieve supersonic speeds with most of the Turbines now available
the
27 pound thrust range. The difficulty comes in matching the turbine to an
airframe. We have designed a target UAV with that potential. The quick
dimensions are 6 feet long 7" tube fuselage, and 34" span 9" chord wing. The
model would weigh 15 pounds at launch. As you can see this doesn't sound
like
much of a sailplane. Launching at a slope would require a zero launch rocket
booster to get to flying speed. If you want to go real fast I might suggest
that you forget about the DSing and build a high powered rocket boost
glider.
My son Chris is heavily involved in high powered rockets, and I am amazed at
the potential thrust from such a light, simple solution. Either way I would
suggest a visit to the optometrist and an autonomous stabilization unit. At
high speeds you can lose sight of them quickly. Have fun and get some
insurance. Larry Sounds like fun I want to see the video.
