These include the issues of cooling the tightly-packaged Rocket engine, together with ensuring the volatile HTP (high test peroxide) doesn't decompose before it reaches the rocket chamber and--in effect--become a bomb.
In the take-off period, the rocket is the main source of engine thrust, most of the fuel reacted in the rocket chamber with the taken oxygen, due to the fuel rich stated of the rocket exhaust, there will be some unreacted fuel left.
The cross-section of the rocket chamber is rectangle with the area is 6 x 20 [mm.sup.2] and the length is 30 mm.
The pressure of the rocket chamber has reached about 0.55 MPa.
At this stage, the temperature inside the rocket chamber soars and ignites the rocket fuel, which sends out a long, thin, orange flame and produces thrust.
The initial runs of the Bloodhound supersonic car in South Africa will be driven by HTP acting as a monopropellant in the rocket chamber. Once the current land speed record is broken, the team will switch to the hybrid rocket to try to push the record over 1,000mph.
Because all this is in the same rocket chamber, the aircraft can take off and land in the same way as a conventional jumbo jet.
To achieve this, they installed precision shutdown ports on the rocket chamber that, when opened in flight, reduced the chamber pressure so abruptly that the propellant was snuffed out.
"We focused strongly on the injection systems of the rockets to produce the optimum distribution of liquid hydrogen and liquid oxygen to avoid combustion instability within the rocket chamber."
Liquid rocket fuels and the oxidizer are held separately in large tanks and then Fed into the rocket chamber, where they mix and burn.
