Orbital to develop next generation UAS engine


PERTH, AUSTRALIA – Orbital is pleased to announce that it has been awarded a contract for
the development of a production engine for a small unmanned aerial system (SUAS). This
United States customer has provided 24/7/365 operations for customers worldwide and has
been delivering Intelligence, Surveillance and Reconnaissance (ISR) capabilities for both land
and maritime missions.
This initial design, development and validation contract of up to $4.5 million will be delivered
throughout 2013 and 2014. Prototype and initial low volume production engines will be
delivered from our existing Balcatta SUAS engine manufacturing facility in Western Australia.
This new engine will utilise Orbital’s FlexDITM Engine Management System (EMS). FlexDI
provides superior fuel preparation with very small fuel droplet size that enables a small spark
ignition engine to run on heavy fuels such as JP5 (naval operations) and JP8 (land based
operations) thus satisfying a U.S. Department of Defence initiative to eliminate gasoline fuels
for safety and logistic reasons – “the one fuel” policy. The system can also satisfy stringent
cold start, and other environmental conditions, required for SUAS applications, without the
need for any fuel pre-heating or other conditioning required by some competitive systems.
The program target is to develop a small engine package that will be durable, fuel efficient and
lightweight, all key factors to provide the desired range and payload capability. A further
advantage of the Orbital Technology is extended range compared to the standard engine
typically used in this class of SUAS; the improved fuel efficiency can increase the range on a
typical mission, or can allow increased payload. Both of these attributes are of critical
importance to the end customer.
Through this program, Orbital will expand its existing business in the SUAS market, a market
with R&D and procurement expenditures of around $5.2 billion per year increasing up to $11.6
billion over the next decade1
To support the anticipated growth in engine production, Orbital plans to develop engine
assembly, testing, and technical support facilities in the USA. This expansion is targeted for
2014-15 and will be based on market demand.

Mr Terry Stinson, CEO and Managing Director of Orbital comments: “Continuing from previous
contracts, the successful development and supply of these engines for this new customer will
position Orbital as the world leader in heavy fuel EMS for the small unmanned aerial systems
market. This is a good example of Australian innovation, and demonstrates Orbital’s
engineering and product development capabilities.”

“The small unmanned aerial systems market is an emerging market for Orbital and we look
forward to realising this potential.” added Mr Stinson.
