ASPIRE II HYBRID MOTOR

The ASPIRE II Rocket makes use of a hybrid motor. Hybrid motors combine good features of both Solid and Liquid Fuelled rockets. They are controllable, semi storable, cheap and simple. They are based on the principle of a solid propellant and a liquid oxidiser.

The hybrid motor under development for ASPIRE II was originally designated the H100 motor (due to the fact that it uses 100 kg of propellant), but due to slight growth, is now known as the H1xx motor.

ASPIRE II SPECIFICATIONS (Provisional)

ASPIRE II THRUST PROFILE

T0 - T+5 seconds: Thrust at 8000 Newtons (Initial acceleration of +5G).

T+5 - T+65 seconds: Thrust at 4000 Newtons (This gives ASPIRE II a sustained burn which provides heavy acceleration at between 40 to 50 Km which accelerates the rocket to Mach 7.5).
