AspireSpace is developing a range of hybrid motors, ranging from
small static test motors, up to large flight capable motors, for use in
the larger ASPIRE rockets which will fly first to space, and then to
orbit.
AspireSpace Hybrid Motor Static Test Firing (throttle tests) - Duration of test
firing - 60 seconds.
The current range of AspireSpace hybrid motors are the:
- H1 - This is the smallest of the Hybrid motors, and is
used as a rapid static testing prototype motor, to evaluate GOX and eventually LOX as the oxidiser.
- H2 - This is the first of the flight configuration Hybrid motors, developed by AspireSpace. The H2 hybrid motor is designed to be the workhorse hybrid motor,
and will be phased in as the standard propulsion system for the ASRV rockets. Designed to test reusability and in-flight throttling, as well as optimum port diameter, regression rates and other empirical data, the H2 hybrid motor will be tested with a range of oxidisers.

- H20 - The H20 hybrid motor is a 50,000 Newton seconds total Impulse Hybrid motor, using 20 kg of propellant. Initially developed as a
reusable static test motor, to allow testing of throttling, port length, and grain
configuration. It will in time be developed to flight configuration,
for use as a high altitude motor, with the steel combustion chamber being replaced with carbon composite.
- Status : Under Construction
- H1xx - The H1xx hybrid motor is a 330,000 Newton
seconds total impulse Hybrid motor, using 100 kg + of propellant. The H1xx will be the first
of the AspireSpace Cryogenic hybrid motors to be flight tested, as it will power the ASPIRE II rocket.
- Status : Design Frozen - awaiting funding
- H1000 - The H1000 hybrid motor is planned to be a 3,000,000 Newton
seconds total impulse Hybrid motor, using 1000 kg of propellant. The
H1000 will be the largest of the AspireSpace hybrid motors, and will be
used in the ASPIRE III sub-orbital rocket, and the AUSROC / ASPIRE
orbital rocket. It is currently in the design stage. Its detailed design
will be dependent on the results of the H100 static test motor firings, as well as the H2 and H20 motors.
