AUSROC 4

Ausroc IV is presently
the final stage of the Ausroc Programs. It is a proposed micro-satellite
orbital launch vehicle to be constructed by clustering four Ausroc III
vehicles (as the first stage) around a fifth vehicle which forms the second
stage. The third stage is to be a solid fuel rocket motor. A significant
amount of design and other work for Ausroc IV has been undertaken since
1990 in parallel with Ausroc III.

In 1996 ASRI acquired
a number of Wedgetail third stage satellite launch vehicle motors from
overseas. These motors are ideally suited as the third stage of Ausroc
IV or as the second stage of a higher performance version of Ausroc III.
Development of a composite solid fuel propellant composition for the Wedgetail
motors (shown below) has been completed by Adelaide University.

Configuration

Preliminary discussions
with the UK based ASPIRESPACE organisation, which has similar objectives
and charter to ASRI, have resulted in positive steps being made towards
the collaborative development of Ausroc IV. Under the collaborative arrangement,
ASPIRESPACE will provide the complete second stage module and assistance
with the third stage hardware.
