Orbital UAV, a manufacturer of integrated propulsion systems, and Animal Dynamics, an uncrewed aerial logistics company have agreed to explore initial concepts for heavy fuel engine systems applicable to Stork-STM, a heavy lift uncrewed aircraft system being developed by the latter. It will result in a highly performing, reliable and maintainable engine that will operate across the wide range of environmental conditions.

As well as powering Stork-STM vehicles, which are being developed for the UK, USA and other allied countries, this engine work will also power a sovereign Australian vehicle, Pelican, being developed in conjunction with Animal Dynamics and Omega Dev Group in Sydney.

Stork STM is an autonomous, heavy lift parafoil built from first engineering principles. It is a new autonomy solution designed to carry heavy cargo weighing 135kg up to 400km (the distance between London and Amsterdam). Operational beyond visual line of sight and able to take off and land across short distances on unprepared ground, it is ideally suited for military resupply, humanitarian aid and emergency response missions.

Orbital UAV's industry leading engine performance and proven ability to operate in extreme temperatures, from -30anddeg;C up to 49anddeg;C, will play a crucial role in the strategic deployment of Stork-STM, bringing a potential global operating domain to a vehicle designed to work in the harshest and most austere environments.

Orbital UAV's rapid in-house prototyping and cradle-to-grave product lifecycle capabilities enable the company to take an engine from concept and definition, through to full rate engine production and in-service support, and will help to accelerate the commercial deployment of Stork-STM.

“Animal Dynamics represents an exciting opportunity to take Orbital UAV's patented engine technology into the European market and expand our global reach,” says Todd Alder, CEO and managing director of Orbital UAV. “Stork-STM is a ground-breaking UAS, that will create a unique solution for the defence sector, and beyond.”

Kevin Allington, CEO of Animal Dynamics, adds: “Orbital represent our first choice to develop the best possible powertrain for our vehicle. We're confident our customers will be able to rely on their performant and reliable technology in the most difficult operating environments.”

“Orbital's world class engineering is another good reason for the Australian Defence Force to be confident that our Pelican UAV brings class leading performance and value for money,” says Blair Hickey CEO of Omega Dev.

Heavy fuel engine capability continues to be a growing requirement for the global UAS market. As more of the market's players look to meet this requirement, Orbital UAV's unique technology and industry leading engine performance continues to expand the Company's customer portfolio.

“The logistical and safety benefits of heavy fuel andndash; combined with Orbital UAV's patented technology and proven capability andndash; continue to drive our global growth opportunity,” says Alder. “We already have established contracts with prime contractors in the USA and our major Singapore defence customer. This opportunity with Animal Dynamics expands our global reach and builds on a number of other near-term opportunities.”
