LOR

Low Orbital Rocket




AIRLIFTING TO 121440 FEET;
*********************************************************************************




The CargoLifter AirCrane CL BCS1 is based on a balloon of 15 m in diameter for a maximum uplift of one (1) ton


http://www.cargolifter.com/products/aircrane/



(1) 3/4 tons to be airlifted.
3-4 balloons should do.

The balloons can get us this far = 23 mi
We need to get past this point = 99 mi

*********************************************************************************

Hybrid liquid/solid rocket.
N20 as a liquid oxidizer.
Hydroxyl-terminated polybutadiene as a solid fuel.

To even the flow of injected N2O into the engine a small Q-Series, 1.9cc 24V compressor is added to each 1 of the 10 N2O tanks. This will trickle psi into each tank as well as normal air...this will only work in atmosphere.( a larger compressor might be needed? )

total weight so far

789 lbs

WARNING: N2O flow may need to be increased with wider channels and increased PSI overall.

Pressurization for each tank is about 800psi which gives us a total of 8000psi.

THE FUEL;
*********************************************************************************





HTPB - Hydroxyl Terminated PolyButadiene R45

http://aeroconsystems.com/cart/motor-making-supplies/htpb-rubber/

This is the classic solid rocket motor binder!
Typical mixing ratio for best cure is 88% HTPB - 12% Papi 94 when mixed with Papi 94, a room temperature cure catalyst.

This is the classic solid rocket motor binder combination! Papi 94 is shipped in a container containing 415 grams of catalyst. This is enough curative to cure one gallon of HTPB.
