What is the micro hybrid, it is a small Hybrid rocket motor that is
D to E power.
The micro hybrid requires no additional ground support than the
standard Estes motor except the hex key that is supplied and a pair
of circlip pliers.
The Micro Hybrid is powered by ISI cream charger bulbs and hence
no expensive NOX tanks and specialist launch controller is required.
The Dimensions of the micro hybrid are 22mm 7/8" diameter by
153mm 6" long plus approx 10mm for the arming screw at the
front.
Depending on fuel grain you use they are high D to E power.
There is no thrust curve for the motor but theoretical values for
the new nylon fuel grain have been developed there are no values for
the paper grains the nylon details are below, this is based on the
standard injector and nozzle that comes with the kit but you can
request custom items with different size's as optional extras. I
hope to have some one put one on a test stand soon so will let you
all know the real world results.
21N for 0.87Second = 18.24Ns Injector diameter is 0.6mm
For the Micro hybrid you do not need an explosive's certificate
but you have to find a way to initiate it, I have used spare
Aerotech delay grains, Aerotech D24 fuel grains and black powder mixed with pva
( not currently legal in the uk ) and I guess
pyrodex would work as well which officially you don't require an
explosives certificate for but some area's do ask to see your explosives
certificate before they will sell you it! It has also been suggested
but not tested to use slow match fuse. One person has even used a
small electronic solenoid a 1.2mm needle and a small welding kit
oxygen bottle to deliver an oxygen rich atmosphere just before
ignition of an igniter similar to the way a Hypertec is lit but with
an igniter instead of the spark although a spark should work as
well.
Recommended Rockets Well any 24mm min diameter that can be
modified to take a 6.25" motor (the motor has a thrust ring)
and has an electronics bay.
I will only recommend recovery
electronics that I have had great success with. These being
Robert Galejs
magnetic apogee sensor.
and the
Perfect Flight Micro Alt
Both suppliers have shipped to the UK as both
are USA based but the Magnetic apogee sensor can now be purchased in
the UK.
