Systeme Solaire has continued to work on the research, design and development of re-usable rocket engines for consumer and aerospace rocketry. Our company philosophy revolves around a commitment to constantly upgrade and improve our products with more lightweight materials and weight saving designs. When the SS67B-1 was completed in 1994, our goal was to begin improving it. We wanted a version that was lighter, more powerful, more versatile, less costly, and easier to launch and recover. Our efforts led to the development of the SS67B-2, and now, the SS67B-3!
The SS67B-3 has several improvements over previous versions. The kit includes a separate casing for increased flight stability, lower engine weight, increased performance, fewer parts (oxidizer tank and fuel tank have been incorporated into one assembly) and is easier to fuel and assemble.
Improvements over the B-2
The safest fuel/oxidizer combination there is!
The oxidizer and fuel are loaded into separate reservoirs before launching. However, to demonstrate the safety of the propellants, the flask to the left is filled with oxidizer (50% Hydrogen Peroxide) and the fuel (gasoline). The combination does not mix due to the difference in densities (ie. similar to when water and oil are mixed). The propellants will not ignite even when in contact with each other (ie. non-hypergolic) and will stay separated!
NO expensive propellant ground support needed!!
Both propellants are liquid at atmospheric pressure. As a result, a small funnel (included in kit) is all you need to load the propellants on the ground. Simply bring the propellants to the launch site in different containers and load the fuel and oxidizer reservoirs by pouring them into their respective chambers! There are no special tanks, fittings, pumps or any other type of equipment required!!
Ground support control included!
To ignite the engine, an ignition control circuit is included! Two timers inside the panel control the ignition sequence. The first timer allows you to move to a safe distance before an ignition is attempted (60 seconds) while the second timer engages the igniter and opens the servo operated valve three seconds later. Power for the circuit is supplied by two 6 volt lantern batteries (not included) or a larger 12 volt source.

SS67B-3 Engine Specifications:
Thrust: 260 Newtons (57.2 lbs)
As with the B-1, The SS67B-3 works on the principle of using a pressurized
gas stored in a high pressure reservoir to force liquid propellants into the
combustion chamber (the pressurized gas is released with a high flow servo actuated
valve). Once in the combustion chamber, the propellants are ignited and the hot
gases are forced through the "convergent-divergent" nozzle producing the thrust.
The propellants are stored in separate reservoirs but consist of one assembly.
Ignition occurs with the help of an ignition circuit.
Once ignition occurs and the 9 second burn is complete, the nose cone
separates from the rest of the assembly due to the drag force of the air
on the fins and casing. The parachute (housed in the nose cone) is pulled
out by the umbilical cord still attached to the engine. Altimeter actuation
of an ejection charge can of course be used as an alternative.
