Schiebel completes heavy fuel acceptance tests for Royal Australian Navy.

Schiebel successfully completed the acceptance tests for the Royal Australian Navy (RAN) of its new Schiebel-designed heavy fuel S2 engine for its CAMCOPTER S-100 Unmanned Air System (UAS).

Building on 12 years of extensive experience developing engines for the CAMCOPTER S-100 system and the lessons learnt from extensive operations worldwide, Schiebel has engineered a new proprietary heavy fuel engine, the S2. Delivered as a next-generation replacement for the current propulsion unit, the S2 further increases the overall capability of the system. The enhancements offered by the S2 engine will enable the RAN to continue to expand their test and evaluation programme, examining advanced Vertical Takeoff and Landing (VTOL) UAS capabilities ahead of the Sea 129 Phase 5 Programme. This programme will select the future UAS capability for the RAN´s new Arafura Class Offshore Patrol Vessels (OPVs) as well as other ships.

Throughout the extensive tests, the CAMCOPTER S-100 system was equipped with a L3 Harris Wescam MX-10 real-time Electro-Optical/Infra-Red (EO/IR) camera, an Automatic Identification System (AIS), a L3 Harris Bandit transceiver and a Mode-S Automatic Dependent Surveillance Broadcast (ADS-B) transponder. This unique configuration provides the operators with the capability to locate and confirm the identity of vessels at sea, as well as transmitting the information in real-time to users equipped with RoverTM remote video terminals.

The new lightweight heavy fuel engine is initially cleared for JP-5 (F-44) and Jet-A1 fuels with other fuel types to be approved in future. Of significant note, this new engine increases the operational performance and maintainability of the S-100 and has sufficient capacity to meet anticipated future market growth needs.
